Accounting Policies [Abstract]
DESCRIPTION OF ORGANIZATION, BUSINESS OPERATIONS AND BASIS OF PRESENTATION	NOTE 1. DESCRIPTION OF ORGANIZATION, BUSINESS OPERATIONS AND BASIS OF PRESENTATION Organization and General Tortoise Acquisition Corp. II (the “Company”) is a blank check company incorporated as a Cayman Islands exempted company on July 24, 2020. The Company was incorporated for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities that the Company has not yet identified (the “Initial Business Combination”). All activity for the period from July 24, 2020 (inception) through December 31, 2020 relates to the Company’s formation and its preparation for the initial public offering (the “Initial Public Offering”), which is described below, and since the closing of the Initial Public Offering, the search for a prospective acquisition target for an Initial Business Combination. The Company will not generate any operating revenue until after the completion of its Initial Business Combination, at the earliest. The Company will generate non-operating income in the form of income earned on investments on investments in the Trust Account (as defined below). The Company has selected December 31 as its fiscal year end. The Company’s sponsor is Tortoise Sponsor II LLC, a Cayman Islands limited liability company (the “Sponsor”). The registration statement for the Initial Public Offering was declared effective on September 10, 2020. On September 15, 2020, the Company consummated the Initial Public Offering of 34,500,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units, the “Public Shares”), including 4,500,000 Units that were issued pursuant to the underwriters’ exercise of their over-allotment option in full, at $10.00 per Unit, generating gross proceeds of $345.0 million, and incurring offering costs of approximately $19.5 million, inclusive of approximately $12.1 million in deferred underwriting commissions (see Note 5). Simultaneously with the closing of the Initial Public Offering, the Company completed the private sale of 5,933,333 warrants at a price of $1.50 per warrant (the “Private Placement Warrants”) in a private placement (the “Private Placement”) to TortoiseEcofin Borrower LLC, a Delaware limited liability company (“TortoiseEcofin Borrower”) and an affiliate of the Sponsor, generating gross proceeds to the Company of approximately $8.9 million (see Note 4). Upon the closing of the Initial Public Offering and the Private Placement, $345.0 million ($10.00 per Unit) of the net proceeds of the Initial Public Offering and certain of the proceeds of the Private Placement were placed in a trust account at J.P. Morgan Chase Bank, N.A. (the “Trust Account”), located in the United States, with Continental Stock Transfer & Trust Company acting as trustee, and will be invested by the trustee only in United States “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 of the Investment Company Act which invest only in direct U.S. government treasury obligations, as determined by the Company, until the earlier of: (i) the completion of an Initial Business Combination and (ii) the distribution of the Trust Account as described below. The Company’s management has broad discretion with respect to the specific application of the net proceeds of its Initial Public Offering and the sale of Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating an Initial Business Combination. The Company’s Initial Business Combination must be with one or more operating businesses or assets with a fair market value equal to at least 80% of the net assets held in the Trust Account (net of amounts disbursed to management for working capital purposes and excluding the amount of any deferred underwriting discount held in trust) at the time the Company signs a definitive agreement in connection with an Initial Business Combination. However, the Company will only complete an Initial Business Combination if the post-combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act. The Company will provide the holders of the Public Shares (the “Public Shareholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of an Initial Business Combination either (a) in connection with a shareholder meeting called to approve the Initial Business Combination or (b) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of an Initial Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Shareholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be $10.00 per share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations). The per-share amount to be distributed to Public Shareholders who redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriters (as discussed in Note 5). These Public Shares were recorded at a redemption value and classified as temporary equity upon the completion of the Initial Public Offering, in accordance with Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” In such case, the Company will proceed with an Initial Business Combination if the Company would have net tangible assets of at least $5,000,001 upon such consummation of the Initial Business Combination and a majority of the shares voted are voted in favor of the Initial Business Combination. If a shareholder vote is not required by law and the Company does not decide to hold a shareholder vote for business or other legal reasons, the Company will, pursuant to the amended and restated memorandum and articles of association which were adopted by the Company in connection with the consummation of the Initial Public Offering (the “Amended and Restated Memorandum and Articles of Association”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (the “SEC”) and file tender offer documents with the SEC prior to completing an Initial Business Combination. If, however, shareholder approval of the transaction is required by law, or the Company decides to obtain shareholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. Additionally, each Public Shareholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. If the Company seeks shareholder approval in connection with an Initial Business Combination, the holders of the Founder Shares (as defined in Note 6) prior to the Initial Public Offering (the “Initial Shareholders”) have agreed to vote their Founder Shares and any Public Shares purchased during or after the Initial Public Offering in favor of an Initial Business Combination. In addition, the Initial Shareholders have agreed to waive their redemption rights with respect to their Founder Shares and Public Shares in connection with the completion of an Initial Business Combination. Notwithstanding the foregoing, the Amended and Restated Memorandum and Articles of Association provide that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 20% or more of the Public Shares, without the prior consent of the Company. The Company’s Sponsor, executive officers and directors have agreed not to propose an amendment to the Amended and Restated Memorandum and Articles of Association that would affect the substance or timing of the Company’s obligation to provide for the redemption of its Public Shares in connection with an Initial Business Combination or to redeem 100% of its Public Shares if the Company does not complete an Initial Business Combination, unless the Company provides the Public Shareholders with the opportunity to redeem their Public Shares in conjunction with any such amendment. If the Company is unable to complete an Initial Business Combination within 24 months from the closing of the Initial Public Offering, or September 15, 2022 (or 27 months from the closing of the Initial Public Offering, or December 15, 2022, if the Company has executed a letter of intent, agreement in principle or definitive agreement for an Initial Business Combination within 24 months from the closing of the Initial Public Offering) (the “Combination Period”), the Company will (a) cease all operations except for the purpose of winding up, (b) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its income taxes (less up to $100,000 of interest to pay dissolution expenses and net of taxes payable), divided by the number of then outstanding Public Shares, which redemption will completely extinguish the Public Shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (c) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the board of directors, dissolve and liquidate, subject in the case of clauses (b) and (c), to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. The Initial Shareholders have agreed to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete an Initial Business Combination within the Combination Period. However, if the Initial Shareholders should acquire Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete an Initial Business Combination within the Combination Period. The underwriters have agreed to waive their rights to their deferred underwriting commission (see Note 5) held in the Trust Account in the event the Company does not complete an Initial Business Combination within the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will only be the $10.00 per share initially held in the Trust Account. In order to protect the amounts held in the Trust Account, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (a) $10.00 per Public Share and (b) the actual amount per Public Share held in the trust account as of the date of the liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have vendors, service providers (except the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. Proposed Business Combination As more fully described in Note 7, on February 7, 2021, the Company entered into a Business Combination Agreement (the “Business Combination Agreement”) with SNPR Merger Sub I, Inc., a Delaware corporation and wholly owned subsidiary of the Company (“First Merger Sub”), SNPR Merger Sub II, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company (“Second Merger Sub”), and Volta Industries, Inc., a Delaware corporation (“Volta”), pursuant to which First Merger Sub will merge with and into Volta (the “First Merger”), with Volta surviving the First Merger as a wholly owned subsidiary of the Company (the “Surviving Corporation”), and the Surviving Corporation will subsequently merge with and into Second Merger Sub (the “Second Merger”) with Second Merger Sub surviving the Second Merger as a wholly owned subsidiary of the Company (the “Proposed Business Combination”). The announcement of the Proposed Business Combination and related agreements were filed with the SEC on a Form 8-K on February 8, 2021. Completion of the Proposed Business Combination is subject to the satisfaction of the conditions stated in the Business Combination Agreement. Liquidity and Capital Resources As of December 31, 2020, the Company had approximately $0.9 million in its operating bank account and working capital of approximately $1.2 million. Through December 31, 2020, the Company’s liquidity needs have been satisfied through a payment of $25,000 of expenses on behalf of the Company by the Sponsor in exchange for the issuance of the Founder Shares, the loan of approximately $181,000 from the Sponsor pursuant to the Note (as defined in Note 4) and the proceeds from the consummation of the Private Placement not held in the Trust Account. The Company fully repaid the Note on September 21, 2020. In addition, in order to finance transaction costs in connection with an Initial Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, provide the Company Working Capital Loans (as defined in Note 4). As of December 31, 2020, there were no amounts outstanding under any Working Capital Loan. Based on the foregoing, the Company’s management believes that the Company will have sufficient working capital and borrowing capacity to meet its needs through the earlier of the consummation of an Initial Business Combination and one year from the date of this report. Over this time period, the Company will be using these funds for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Initial Business Combination.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying financial statements of the Company have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC. Emerging Growth Company As an emerging growth company, the Company may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. This may make comparison of the Company’s financial statement with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist of a cash account in a financial institution which, at times, may exceed the Federal Depository Insurance Corporation coverage limits of $250,000, and any cash held in Trust Account. At December 31, 2020, the Company had not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. Financial Instruments As of December 31, 2020, the carrying values of cash, prepaid expenses, accounts payable, and accrued expenses approximate their fair values due to the short-term nature of the instruments. Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. There were no cash equivalents as of December 31, 2020. Offering Costs Associated with the Initial Public Offering Offering costs consisted of legal, accounting, underwriting fees and other costs incurred that were directly related to the Initial Public Offering. These costs were charged to shareholders’ equity upon the completion of the Initial Public Offering. Class A Ordinary Shares Subject to Possible Redemption The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Class A ordinary shares subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Conditionally redeemable Class A ordinary shares (including Class A ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A ordinary shares are classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, at December 31, 2020, 32,901,830 Class A ordinary shares subject to possible redemption are presented as temporary equity, outside of the shareholders’ equity section of the Company’s balance sheet. Net Loss Per Ordinary Share The Company complies with accounting and disclosure requirements of ASC Topic 260, “Earnings Per Share.” Net loss per ordinary share is computed by dividing net loss by the weighted average number of ordinary shares outstanding during the period. The Company has not considered the effect of the Public Warrants (as defined below) and the Private Placement Warrants to purchase an aggregate of 14,558,333 Class A ordinary shares in the calculation of diluted earnings per share, since their inclusion would be anti-dilutive under the treasury stock method. The Company’s statement of operations include a presentation of income per share for ordinary shares subject to redemption in a manner similar to the two-class method of income per share. Net loss per share, basic and diluted for Class A ordinary shares is calculated by dividing the investment income earned on the Trust Account of $0 for the period from July 24, 2020 (inception) through December 31, 2020 by the weighted average number of Class A ordinary shares outstanding for the period. Net loss per share, basic and diluted for Class B ordinary shares is calculated by dividing the net loss of approximately $364,000, less income attributable to Class A ordinary shares, by the weighted average number of Class B ordinary shares outstanding for the period. Income Taxes ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s only major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2020. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is considered an exempted Cayman Islands company and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the periods presented. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. Recent Accounting Pronouncements Management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s financial statements.

INITIAL PUBLIC OFFERING On September 15, 2020, the Company consummated the Initial Public Offering of 34,500,000 Units, including 4,500,000 Units that were issued pursuant to the underwriters’ exercise of their over-allotment option in full, at $10.00 per Unit, generating gross proceeds of $345.0 million, and incurring offering costs of approximately $19.5 million, inclusive of approximately $12.1 million in deferred underwriting commissions. Each Unit consists of one Class A ordinary share and one-fourth of one redeemable warrant (“Public Warrant”). Each whole Public Warrant will entitle the holder to purchase one Class A ordinary share at an exercise price of $11.50 per share, subject to adjustment (see Note 6).

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	NOTE 4. RELATED PARTY TRANSACTIONS Founder Shares On July 29, 2020, the Sponsor paid an aggregate of $25,000 for certain expenses on behalf of the Company in exchange for issuance of 7,187,500 Founder Shares. In September 2020, the Company effected a share capitalization of 1,437,500 Founder Shares, resulting in the Sponsor holding an aggregate of 8,625,000 Founder Shares. All shares and associated amounts have been retroactively restated to reflect the share capitalization. The holders of the Founder Shares agreed to forfeit up to an aggregate of 1,125,000 Founder Shares, on a pro rata basis, to the extent that the option to purchase additional units is not exercised in full by the underwriters, so that the Founder Shares would represent 20% of the Company’s issued and outstanding shares after the Initial Public Offering. The over-allotment option was exercised in full on September 11, 2020; thus, these shares are no longer subject to forfeiture. The holders of the Founder Shares have agreed, subject to limited exceptions, not to transfer, assign or sell any of their Founder Shares until the earlier to occur of: (a) one year after the completion of the Initial Business Combination and (b) subsequent to the Initial Business Combination, (i) if the last reported sale price of the Company’s Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the consummation of the Initial Business Combination, and (ii) the date on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the Company’s shareholders having the right to exchange their ordinary shares for cash, securities or other property. Private Placement Simultaneously with the closing of the Initial Public Offering, the Company completed the private sale of 5,933,333 Private Placement Warrants at a price of $1.50 per Private Placement Warrant to TortoiseEcofin Borrower, generating gross proceeds to the Company of approximately $8.9 million. Each Private Placement Warrant is exercisable for one whole Class A ordinary share at a price of $11.50 per share. A portion of the proceeds from the sale of the Private Placement Warrants were added to the proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete an Initial Business Combination within the Combination Period, the Private Placement Warrants will expire worthless. The Private Placement Warrants will be non-redeemable for cash and exercisable on a cashless basis so long as they are held by TortoiseEcofin Borrower or its permitted transferees. TortoiseEcofin Borrower and the Company’s officers and directors agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Warrants until 30 days after the completion of the Initial Business Combination. Related Party Loans On July 29, 2020, the Sponsor agreed to loan the Company up to $600,000 to be used for the payment of costs related to the Initial Public Offering pursuant to a promissory note (the “Note”). The Note was non-interest bearing, unsecured and due upon the closing of the Initial Public Offering. The Company borrowed approximately $181,000 under the Note and repaid the Note in full on September 21, 2020. In addition, in order to finance transaction costs in connection with an Initial Business Combination, the Sponsor, certain of the Company’s officers and directors or any of their respective affiliates may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes an Initial Business Combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that an Initial Business Combination is not completed within the Combination Period, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans, but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. The Working Capital Loans would either be repaid upon consummation of an Initial Business Combination, without interest, or, at the lender’s discretion, up to $1.5 million of such Working Capital Loans may be convertible into warrants of the post-combination company at a price of $1.50 per warrant. The warrants would be identical to the Private Placement Warrants. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. As of December 31, 2020, the Company had no borrowings under the Working Capital Loans. Administrative Services Agreement Pursuant an Administrative Services Agreement between the Company and Tortoise Capital Advisors, L.L.C. (“Tortoise Capital Advisors”), dated September 10, 2020 (the “Administrative Services Agreement”), the Company agreed to pay Tortoise Capital Advisors a total of $10,000 per month for office space, utilities and administrative support. Upon completion of the Initial Business Combination or the Company’s liquidation, the agreement will terminate. During the period from July 24, 2020 (inception) through December 31, 2020, the Company incurred $36,667 in expenses for these services, which is included in administrative expenses – related party on the accompanying statement of operations. No amount was due as of December 31, 2020. In addition, the Sponsor, the Company’s officers and directors or any of their respective affiliates will be reimbursed for any out-of-pocket expenses incurred in connection with activities on the Company’s behalf such as identifying potential partner businesses and performing due diligence on a suitable Initial Business Combination. The Company’s audit committee will review on a quarterly basis all payments that were made by the Company to the Sponsor, the Company’s officers or directors or any affiliates of the Company or the Company’s officers or directors. Any such payments prior to an Initial Business Combination will be made using funds held outside the Trust Account.

COMMITMENTS AND CONTINGENCIES	NOTE 5. COMMITMENTS AND CONTINGENCIES Registration and Shareholder Rights The holders of the Founder Shares, Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans (and any Class A ordinary shares issuable upon the exercise of the Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans and upon conversion of the Founder Shares), and any Class A ordinary shares held by the Initial Shareholders, the Sponsor and TortoiseEcofin Borrower at the completion of the Initial Public Offering or acquired prior to or in connection with the Initial Business Combination, are entitled to registration rights pursuant to a registration rights agreement. The holders of these securities are entitled to make up to three demands that the Company offer such securities in an underwritten offering. These holders also have certain “piggy-back” registration rights with respect to certain underwritten offerings the Company may conduct. The Company will bear the expenses incurred in connection with the registration of such securities. Underwriting Agreement The Company granted the underwriters a 45-day option to purchase up to 4,500,000 additional Units at the Initial Public Offering price of $10.00 per Unit, less the underwriting discounts and commissions. The underwriters exercised the over-allotment option in full on September 11, 2020. The underwriters were entitled to an underwriting discount of $0.20 per Unit, or $6.9 million in the aggregate, paid upon the closing of the Initial Public Offering. In addition, $0.35 per Unit, or approximately $12.1 million in the aggregate, will be payable to the underwriters for deferred underwriting commissions. The deferred fee will become payable to the underwriters from the amount held in the Trust Account solely in the event that the Company completes an Initial Business Combination, subject to the terms of the underwriting agreement. Deferred Legal Fees Associated with the Initial Public Offering The Company entered into an engagement letter to obtain legal advisory services, pursuant to which the Company’s legal counsel agreed to defer half of their fees until the closing of the Initial Business Combination. As of December 31, 2020, the Company recorded an aggregate of $150,000 in connection with such arrangement as deferred legal fees in the accompanying balance sheet. Forward Purchase Agreement The Company entered into a forward purchase agreement (the “Forward Purchase Agreement”), pursuant to which the Company may elect, in its sole and absolute discretion, to offer CIBC National Trust Company (“CIBC National Trust”) the opportunity to purchase forward purchase units, consisting of one Class A ordinary share (the “Forward Purchase Shares”) and one-fourth of one redeemable warrant (the “Forward Purchase Warrants”), where each whole redeemable warrant is exercisable to purchase one Class A ordinary share at an exercise price of $11.50 per share (the “Forward Purchase Units”), and, if CIBC National Trust accepts such offer, it commits to purchase at least a minimum aggregate amount equal to either (a) 10% of the gross proceeds from a private placement that may close simultaneously with the closing of the Initial Business Combination or (b) 10% of the gross proceeds from the Initial Public Offering (the “Minimum Aggregate Amount”), and up to a maximum aggregate amount of $100,000,000 of Forward Purchase Units at a price per unit equal to the public offering price (the “Maximum Aggregate Amount”). The Forward Purchase Shares will be identical to the Class A ordinary shares included in the Units sold in the Initial Public Offering and the Forward Purchase Warrants will have the same terms as the Public Warrants, except the Forward Purchase Shares and the Forward Purchase Warrants will be subject to transfer restrictions and certain registration rights. The funds from the sale of the Forward Purchase Units may be used as part of the consideration to the sellers in the Initial Business Combination, and any excess funds may be used for the working capital needs of the post-transaction company. The Forward Purchase Agreement is subject to conditions, including CIBC National Trust specifying the amount of Forward Purchase Units between the Minimum Aggregate Amount and Maximum Aggregate Amount (the “Specified Amount”) it wishes to purchase after the Company notifies CIBC National Trust of its intention to offer CIBC National Trust the opportunity to purchase Forward Purchase Units. The Company may specify, in its sole and absolute discretion and at any time prior to or after CIBC National Trust has indicated its Specified Amount, an amount below the Specified Amount that the Company is willing to sell to CIBC National Trust. CIBC National Trust may choose to accept the Company’s offer to purchase the Forward Purchase Units entirely within its sole discretion. Accordingly, if CIBC National Trust does not accept the Company’s offer to purchase the Forward Purchase Units, it will not be obligated to purchase the Forward Purchase Units. In connection with the Company entering into the Business Combination Agreement, the Company entered into a subscription agreement with CIBC National Trust pursuant to which CIBC National Trust agreed to purchase, subject to the satisfaction of applicable closing conditions, shares of our Class A Common Stock (as defined in Note 7). As a result, on February 8, 2021, the Company delivered a notice to CIBC National Trust stating that it will not elect to offer CIBC National Trust the opportunity to purchase Forward Purchase Units pursuant to the Forward Purchase Agreement. Risks and Uncertainties Management continues to evaluate the impact of the COVID-19 pandemic and has concluded that, while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations and/or search for a target company and the closing of an Initial Business Combination, the specific impact is not readily determinable as of the date of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Stockholders' Equity Note [Abstract]
SHAREHOLDERS’ EQUITY	NOTE 6. SHAREHOLDERS’ EQUITY Class A Ordinary Shares Class B Ordinary Shares Ordinary shareholders of record are entitled to one vote for each share held on all matters to be voted on by shareholders. Holders of Founder Shares will have the right to elect all of the Company’s directors prior to the Initial Business Combination. On any other matter submitted to a vote of the Company’s shareholders, holders of the Class A ordinary shares and holders of the Founder Shares will vote together as a single class on all matters submitted to a vote of the Company’s shareholders except as required by law or stock exchange rule. The Founder Shares will automatically convert into Class A ordinary shares at the time of the Initial Business Combination on a one-for-one basis (subject to adjustment for share sub-divisions, share dividends, reorganizations, recapitalizations and the like), and subject to further adjustment as provided herein. In the case that additional Class A ordinary shares, or equity-linked securities, are issued or deemed issued in excess of the amounts sold in the Initial Public Offering and related to the closing of the Initial Business Combination, the ratio at which Founder Shares shall convert into Class A ordinary shares will be adjusted (unless the holders of a majority of the outstanding Founder Shares agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of Class A ordinary shares issuable upon conversion of all Founder Shares will equal, in the aggregate, on an as-converted basis, 20% of the sum of the total number of all ordinary shares outstanding upon completion of the Initial Public Offering plus all Class A ordinary shares and equity-linked securities issued or deemed issued in connection with the Initial Business Combination (excluding any shares or equity-linked securities issued, or to be issued, to any seller in the Initial Business Combination). In connection with the Company entering into the Business Combination Agreement, subject to the closing thereof, the Sponsor and the Initial Shareholders agreed to waive the anti-dilution rights set forth in the Amended and Restated Memorandum and Articles of Association Preference Shares Warrants The warrants have an exercise price of $11.50 per share, subject to adjustments, and will expire five years after the completion of an Initial Business Combination or earlier upon redemption or liquidation. In addition, if the Company issues additional Class A ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of the Initial Business Combination at an issue price or effective issue price of less than $9.20 per share of Class A ordinary shares (with such issue price or effective issue price to be determined in good faith by the board and, in the case of any such issuance to the Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the Newly Issued Price. The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants and the Class A ordinary shares issuable upon exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of an Initial Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. Once the warrants become exercisable, the Company may redeem the outstanding warrants for cash (except as described herein with respect to the Private Placement Warrants): ● in whole and not in part; ● at a price of $0.01 per warrant; ● upon a minimum of 30 days’ prior written notice of redemption; and ● if, and only if, the last sale price of Class A ordinary shares equals or exceeds $18.00 per share (as adjusted for share sub-divisions, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders. The Company will not redeem the warrants for cash unless a registration statement under the Securities Act covering the Class A ordinary shares issuable upon exercise of the warrants is effective and a current prospectus relating to those Class A ordinary shares is available throughout the 30-day redemption period, except if the warrants may be exercised on a cashless basis and such cashless exercise is exempt from registration under the Securities Act. Commencing 90 days after the warrants become exercisable, the Company may redeem the outstanding warrants for Class A ordinary shares: ● in whole and not in part; ● at a price equal to a number of Class A ordinary shares to be determined by reference to an agreed table based on the redemption date and the “fair market value” of Class A ordinary shares; ● upon a minimum of 30 days’ prior written notice of redemption; and ● if, and only if, the last sale price of Class A ordinary shares equals or exceeds $10.00 per share (as adjusted per share sub-divisions, share dividends, reorganizations, recapitalizations and the like) on the trading day prior to the date on which the Company sends the notice of redemption to the warrant holders. The “fair market value” of Class A ordinary shares shall mean the average reported last sale price of Class A ordinary shares for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants. In no event will the Company be required to net cash settle any warrant. If the Company is unable to complete an Initial Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless.

The announcement of the Proposed Business Combination and related agreements were filed with the SEC on a Form 8-K on February 8, 2021. Completion of the Proposed Business Combination is subject to the satisfaction of the conditions stated in the Business Combination Agreement. Prior to the effective time of the First Merger (the “Effective Time”), the Company will domesticate (the “Domestication”) as a Delaware corporation in accordance with Section 388 of the Delaware General Corporation Law (the “DGCL”) and the applicable provisions of the Companies Act (2020 Revision) of the Cayman Islands (the “Companies Act”).

Stockholder Support Agreement In connection with the execution of the Business Combination Agreement, the Company entered into a Stockholder Support Agreement (the “Stockholder Support Agreement”) with Volta and certain shareholders of Volta pursuant to which such shareholders agreed to vote all of their shares of Volta’s Class A common stock, par value $0.001 per share (“Volta Class A Common Stock”) and shares of Volta’s Class B common stock, par value $0.001 per share (“Volta Class B Common Stock” and, together with the Volta Class A Common Stock, the “Volta Common Stock”) and shares of Volta’s preferred stock (“Volta Preferred Stock”) in favor of the approval and adoption of the Proposed Business Combination and related transactions (the “Proposed Transactions”), including agreeing to execute a written consent within forty-eight hours of a registration statement on Form S-4 filed by the Company becoming effective. Additionally, such shareholders have agreed, among other things, not to, prior to the Effective Time (a) transfer any of their shares of Volta Common Stock and Volta Preferred Stock (or enter into any arrangement with respect thereto), subject to certain customary exceptions or (b) enter into any voting arrangement that is inconsistent with the Stockholder Support Agreement. Lock-Up Agreement In connection with the execution of the Business Combination Agreement, the founders of Volta entered into a Lock-Up Agreement with the Company and Volta pursuant to which they have agreed, subject to certain customary exceptions, not to effect any (a) direct or indirect sale, assignment, pledge, hypothecation, disposition, loan or other transfer, or entry into any agreement with respect to any sale, assignment, pledge, hypothecation, disposition, loan or other transfer, with respect to any shares of the Company’s domesticated Class A common stock (the “Class A Common Stock”) or domesticated Class B common stock (the “Class B Common Stock”) held by them immediately after the Effective Time, including any shares of Class A Common Stock or Class B Common Stock issuable upon the exercise of options or warrants to purchase shares of Class A Common Stock or Class B Common Stock held by them immediately following the closing of the Proposed Transactions (the “BCA Closing”) or (b) publicly announce any intention to effect any transaction specified in clause (a), in each case, until the date that is the earlier of (i) one year after the BCA Closing and (ii) the earlier to occur of, subsequent to the BCA Closing, (x) the first date on which the last reported sale price of the Class A Common Stock equals or exceeds $12.00 per share (as equitably adjusted for share sub-divisions, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30 trading-day period commencing at least 150 days after the BCA Closing and (y) the date on which there is consummated a subsequent liquidation, merger, share exchange or other similar transaction which results in all of the Company’s stockholders having the right to exchange their shares of Class A Common Stock for cash, securities or other property. The Company’s bylaws after the BCA Closing will include transfer restrictions on its securities issued to the investors of Volta in connection with the First Merger for a period of six (6) months after the BCA Closing. Sponsor Letter In connection with the execution of the Business Combination Agreement, the Company entered into a letter agreement with Volta, the Sponsor and the other holders of the Founder Shares pursuant to which, among other things, the Sponsor and each other holder agreed to (a) waive the anti-dilution rights set forth in Article 17.3 of the amended and restated memorandum and articles of association, (b) comply with the non-solicitation provisions in the Business Combination Agreement and (c) vote all of the Company’s ordinary shares held by them in favor of the adoption and approval of the Business Combination Agreement and the Proposed Transactions. Subscription Agreements In connection with the execution of the Business Combination Agreement, the Company entered into separate subscription agreements (collectively, the “Subscription Agreements”) with a number of investors (each, a “Subscriber” and collectively, the “Subscribers”), pursuant to which the Subscribers agreed to purchase, and the Company agreed to sell to the Subscribers, an aggregate of 30,000,000 shares of Class A Common Stock (the “Private Placement Shares”), for a purchase price of $10.00 per share and an aggregate purchase price of $300,000,000, in a private placement. The closing of the sale of the Private Placement Shares pursuant to the Subscription Agreements will take place on the date of, and at a time immediately prior to or substantially concurrently with, the BCA Closing and is contingent upon, among other customary closing conditions, the consummation of the Proposed Transactions. The purpose of the Private Placement is to raise additional capital for use by the combined company following the BCA Closing. Pursuant to the Subscription Agreements, the Company agreed that, within 30 calendar days after the consummation of the Proposed Transactions, it will file with the SEC (at the Company’s sole cost and expense) a registration statement registering the resale of the Private Placement Shares (the “Private Placement Resale Registration Statement”), and to use commercially reasonable efforts to have the Private Placement Resale Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) 60 calendar days (or 90 calendar days if the SEC notifies the Company that it will review the Private Placement Resale Registration Statement) following the BCA Closing and (ii) the tenth business day after the SEC notifies the Company that the Private Placement Resale Registration Statement will not be reviewed or will not be subject to further review. Also, in January 2021, in connection with the Proposed Transactions, the Company engaged Barclays Capital Inc. (“Barclays”) and Goldman Sachs & Co LLC (“Goldman” and, together with Barclays, the “Placement Agents”) pursuant to an engagement letter to act as co-placement agents in connection with the potential sale of its equity-linked securities to one or more financial investors. An aggregate fee of 3.0% of the gross proceeds received by the Company from a sale of the securities in such offering (or $9.0 million) will be payable to the Placement Agents, subject to the completion of the offering. The Company also engaged Barclays under such engagement letter to act as the Company’s financial advisor and capital markets advisor in connection with the Proposed Transactions, and the Company agreed to pay a fee of $3.0 million to Barclays for such services, subject to the consummation of the Proposed Transactions. The Company evaluated subsequent events and transactions that occurred after the balance sheet date through March 19, 2021, the date the financial statements were issued. Other than as described herein, the Company did not identify any other subsequent events that would have required adjustment or disclosure in the financial statements.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying financial statements of the Company have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC.
Emerging Growth Company	Emerging Growth Company As an emerging growth company, the Company may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. This may make comparison of the Company’s financial statement with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist of a cash account in a financial institution which, at times, may exceed the Federal Depository Insurance Corporation coverage limits of $250,000, and any cash held in Trust Account. At December 31, 2020, the Company had not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.
Financial Instruments	Financial Instruments As of December 31, 2020, the carrying values of cash, prepaid expenses, accounts payable, and accrued expenses approximate their fair values due to the short-term nature of the instruments.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. There were no cash equivalents as of December 31, 2020.
Offering Costs Associated with the Initial Public Offering	Offering Costs Associated with the Initial Public Offering Offering costs consisted of legal, accounting, underwriting fees and other costs incurred that were directly related to the Initial Public Offering. These costs were charged to shareholders’ equity upon the completion of the Initial Public Offering.
Class A Ordinary Shares Subject to Possible Redemption	Class A Ordinary Shares Subject to Possible Redemption The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Class A ordinary shares subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Conditionally redeemable Class A ordinary shares (including Class A ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A ordinary shares are classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, at December 31, 2020, 32,901,830 Class A ordinary shares subject to possible redemption are presented as temporary equity, outside of the shareholders’ equity section of the Company’s balance sheet.
Net Loss Per Ordinary Share	Net Loss Per Ordinary Share The Company complies with accounting and disclosure requirements of ASC Topic 260, “Earnings Per Share.” Net loss per ordinary share is computed by dividing net loss by the weighted average number of ordinary shares outstanding during the period. The Company has not considered the effect of the Public Warrants (as defined below) and the Private Placement Warrants to purchase an aggregate of 14,558,333 Class A ordinary shares in the calculation of diluted earnings per share, since their inclusion would be anti-dilutive under the treasury stock method. The Company’s statement of operations include a presentation of income per share for ordinary shares subject to redemption in a manner similar to the two-class method of income per share. Net loss per share, basic and diluted for Class A ordinary shares is calculated by dividing the investment income earned on the Trust Account of $0 for the period from July 24, 2020 (inception) through December 31, 2020 by the weighted average number of Class A ordinary shares outstanding for the period. Net loss per share, basic and diluted for Class B ordinary shares is calculated by dividing the net loss of approximately $364,000, less income attributable to Class A ordinary shares, by the weighted average number of Class B ordinary shares outstanding for the period.
Income Taxes	Income Taxes ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s only major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2020. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is considered an exempted Cayman Islands company and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the periods presented. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s financial statements.
