Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Organization and Business Operations	1. Description of Organization and Business Operations Organization and General Sentinel Energy Services Inc. (the “Company”) was incorporated in the Cayman Islands on June 5, 2017. The Company was formed as a blank check company for the purpose of effecting a merger, amalgamation, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended (the “Securities Act”), as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). The Company is also a “smaller reporting company” as defined in the Exchange Act of 1934, as amended (the “Exchange Act”). On December 28, 2018, the Company changed its jurisdiction of incorporation from the Cayman Islands (“Sentinel Cayman”) to the State of Delaware (“Sentinel Delaware”), as described further below (the “Domestication”) and continued to be named Sentinel Energy Services Inc. As a result of the Domestication, the securities of Sentinel Cayman converted into securities of Sentinel Delaware, such that Sentinel Cayman’s issued and outstanding Class A ordinary shares (the “Class A ordinary shares”) and Class B ordinary shares (the “Class B ordinary shares”) automatically converted by operation of law into one share of Class A common stock (“Class A common stock”) and Class B common stock (“Class B common stock”), of Sentinel Delaware, respectively. Similarly, each of Sentinel Cayman’s outstanding units and warrants automatically converted by operation of law, on a one-for-one basis, into Units (as defined below) of Sentinel Delaware and warrants, including the Private Placement Warrants and Public Warrants (each as defined below) to acquire the corresponding number of shares of Class A common stock, respectively. Accordingly, all references to the Company’s capital stock both before and after the Domestication are referred to as shares of “common stock” in this filing. At September 30, 2021, the Company had not yet commenced operations. All activity through September 30, 2021 relates to (1) the Company’s formation and issuance of the Founder Shares (as defined in Note 4), (2) the Public Offering (as defined below) and sale of warrants in a private placement to our Sponsor (the “Private Placement Warrants”) which closed in November 2017, (3) the subsequent a search for a business combination candidate, including activities in connection with an announced and subsequently terminated proposed business combination and (4) liquidation activities, including liquidation of the Trust Account (as defined below), following the Company’s inability to consummate a business combination prior to the November 7, 2019 deadline under the Company certificate of incorporation (the “Charter”). The Company has not generated any operating revenues since inception. The Company generated non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the Public Offering and sale of Private Placement Warrants until November 2019. The Company intended to finance its initial business combination with proceeds from the Company’s initial public offering (the “Public Offering”) of the Company units (“Units”) and the sale of the Private Placement Warrants. Each Unit consisted of (A) one share of the Company’s Class A common stock, par value $0.0001 per share (the “Public Shares”), and (B) one-third of one warrant exercisable to purchase one share of the Company’s Class A common stock (each whole warrant, a “Public Warrant”), and from the Company’s private placement sale of warrants exercisable to purchase one share of Company’s Class A common stock (each, a “Private Placement Warrant”) to the Sentinel Management Holdings, LLC (the “Sponsor”). Upon the closings of the Public Offering and the sale of the Private Placement Warrants, approximately $345,000,000 was placed in a trust account (the “Trust Account”). The Company was not able to consummate a business combination prior to the November 7, 2019 deadline under the Company’s Charter. As a result, the Company commenced the liquidation of the Trust Account, which then had a balance of approximately $355,500,000, and returned the funds held therein to its public stockholders by redeeming 100% of the Public Shares in accordance with the Charter. During the liquidation period, the Company and the holders of the Public Warrants also executed an amendment to the Warrant Agreement, dated as of November 2, 2017, by and between the Company and Continental Stock Transfer & Trust Company, which automatically converted the Public Warrants into the right to receive $0.02 per whole Public Warrant, payable in cash. The redemption of the Public Shares and the conversion of the Public Warrants completely extinguished the public stockholders’ rights in the Company. In addition, the Sponsor forfeited the Private Placement Warrants as a result of the Company being unable to consummate a business combination prior to the deadline in its Charter. In connection with the redemption of the Public Shares, each stockholder received approximately $10.30 per share on November 18, 2019. The Company withheld approximately $1,350,000 from the distribution. In April 2020, the Company paid the income tax liability for the year ended December 31, 2019 of $259,284 and, following payment of distribution settlement expenses of $100,351, the Company distributed the remaining $1,152,035 to its public stockholders on May 4, 2020 for a distribution of approximately $0.03 per share. The Trust Account was subsequently closed with no balance remaining. In December 2019, the Company paid $225,990 in connection with the conversion of the Public Warrants. Following the redemption of the Public Shares, the conversion of the Public Warrants and the forfeiture of the Private Placement Warrants, there were no Units, Public Shares, Public Warrants or Private Placement Warrants outstanding. Additional shares of Class A common stock were subsequently issued and shares of Class B common stock remain outstanding. For more information on additional issuances, see Note 4. Initial Business Combination The Company’s management had broad discretion with respect to the specific application of the net proceeds of the Public Offering, although substantially all of the net proceeds of the Public Offering were intended to be generally applied toward consummating an initial business combination. The Charter and the prospectus that the Company filed in connection with the Public Offering provided that the Company had 24 months after the closing of its Public Offering, or until November 7, 2019, to complete a business combination. During the period since the Company’s Public Offering, the Company diligently searched for a business to combine with in a transaction that would generate value for the Company’s stockholders; however, over the same period, the energy sector experienced significant headwinds, which increased the challenges faced by the Company in sourcing a compelling target business. Despite the Company’s best efforts, it was not able to consummate a business combination prior to the November 7, 2019 deadline under its Charter. As a result, the Company commenced the liquidation of the Trust Account and returned the funds held therein to its public stockholders by redeeming 100% of the Company’s Public Shares in accordance with the Charter, which together with the conversion of the Public Warrants extinguished the public stockholders’ rights in the Company. Underwriting Discount Upon closing of the Public Offering, the Company paid an underwriting discount of 2.0% of the per Unit offering price to the underwriters with an additional fee (the “Deferred Discount”) of 3.5% ($12,075,000) of the gross offering proceeds payable upon the Company’s completion of an initial business combination. The underwriters were not entitled to any interest accrued on the Deferred Discount. In accordance with the terms of the underwriting agreement entered into in connection with the Public Offering, the underwriters forfeited any rights or claims to the Deferred Discount because the Company was unable to consummate an initial business combination by the November 7, 2019 deadline under its Charter. Liquidity In connection with the Company’s assessment of going concern considerations in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Update (“ASU”) 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern , Pursuant a commitment letter from the Sponsor, the Sponsor intends to financially support the Company sufficient for the Company to satisfy its working capital needs until at least November 15, 2022. For additional information, see the information under the captions “Advances from Related Parties,” “Promissory Note Payable – Sponsor,” “Contributions from Related Party” and “Administrative Support Agreement” in Note 4.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed financial statements of the Company are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the accounting and disclosure rules and regulations of the Securities and Exchange Commission (the “SEC”), and reflect all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the financial position as of September 30, 2021 and the results of operations and cash flows for the periods presented. Certain information and disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations. Interim results are not necessarily indicative of results for a full year. The accompanying unaudited condensed financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Annual Report on Form 10-K filed by the Company with the SEC on March 31, 2021. Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the JOBS Act, and it 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, 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 stockholder 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 a 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 (i) not an emerging growth company or (ii) 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. 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 expenses during the reporting periods. Actual results could differ from those estimates. 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 credit limit of $250,000. At September 30, 2021 and 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. Risks and Uncertainties Management continues to evaluate the impact of the COVID-19 pandemic on the industry and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position and results of its operations, 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. Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures 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. The Company had no cash equivalents as of September 30, 2021 and December 31, 2020. Net Loss Per Share of Common Stock Net loss per share of common stock is computed by dividing net loss applicable to the shares of common stock by the weighted average number of shares outstanding for the periods. As a result of the redemption of Public Shares in November 2019, for the three and nine months ended September 30, 2021 and 2020, the Class A shares have no specific redemption rights. As a result, net loss per common share is calculated by dividing the net loss by the weighted average number of Class A and Class B shares outstanding for the periods. Income Taxes The Company follows the asset and liability method of accounting for income taxes under FASB ASC Topic 740, Income Taxes FASB Topic ASC 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. There were no unrecognized tax benefits as of September 30, 2021 and December 31, 2020. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties at September 30, 2021 and 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 subject to income tax examinations by major taxing authorities since inception. The Company may be subject to potential examination by federal, state, and city taxing authorities in the areas of income taxes. These potential examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions, and compliance with federal, state, and city tax laws. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. During the three and nine months ended September 30, 2021 and 2020, the Company recorded income tax expense of $0. Subsequent Events The Company evaluates subsequent events and transactions that occur after the balance sheet date for potential recognition or disclosure. Any material events that occur between the balance sheet date and the date that the unaudited condensed financial statements were issued are disclosed as subsequent events, while the unaudited condensed financial statements are adjusted to reflect any conditions that existed at the balance sheet date. Recent Accounting Pronouncements The Company’s management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have an effect on the Company’s financial statements.

Public Offering Private Placement Warrants [Abstract]
Public Offering and Private Placement Warrants	3. Public Offering and Private Placement Warrants In November 2017, the Company closed its Public Offering of 34,500,000 units at a price of $10.00 per Unit, with gross proceeds of $345,000,000 from the sale of Units. The closings occurred on November 7, 2017 with respect to 30,000,000 Units and on November 9, 2017 with respect to 4,500,000 Units related to the exercise of the underwriters’ overallotment option. During the liquidation period, the Company and the holders of its Public Warrants executed an amendment to the Warrant Agreement, dated as of November 2, 2017, between the Company and Continental Stock Transfer & Trust Company, to automatically convert each of the Company’s all of the outstanding Public Warrants into the right to receive $0.02 per whole Public Warrant, payable in cash. In December 2019, the Company paid $225,990 to its warrant holders in connection with the conversion of the Public Warrants. Simultaneously with the closing of the Public Offering on November 7, 2017, the Sponsor purchased an aggregate of 5,333,333 Private Placement Warrants at a price of $1.50 per whole warrant ($8,000,000 in gross proceeds) in a private placement. Simultaneously with the closing of the overallotment, the Company consummated the private placement of an additional 600,000 Private Placement Warrants to the Sponsor, generating additional gross proceeds of $900,000. The Company paid an underwriting discount of 2.0% of the per Unit offering price to the underwriters at the closing of the Public Offering, with the Deferred Discount payable upon the Company’s completion of an initial business combination. The Deferred Discount was payable to the underwriters from the amounts held in the Trust Account solely in the event the Company completed its initial business combination. In accordance with the terms of the underwriting agreement entered into in connection with the Public Offering, the underwriters forfeited any rights or claims to the Deferred Discount because the Company was unable to consummate an initial business combination by the November 7, 2019 deadline under its Charter. Following the redemption of the Public Shares, the conversion of the Public Warrants and the forfeiture of the Private Placement Warrants, there were no Units, Public Shares, Public Warrants or Private Placement Warrants outstanding. Additional shares of Class A common stock were subsequently issued and shares of Class B common stock remain outstanding. For more information on additional issuances, see Note 4.

Related Party Transactions [Abstract]
Related Party Transactions	4. Related Party Transactions Founder Shares In June 2017 prior to the Public Offering, the Sponsor entered into an Amended and Restated Securities Purchase Agreement, for the purchase of 14,375,000 shares of Class B common stock (the “Founder Shares”) for $25,000, or approximately $0.002 per share. The Sponsor is a portfolio company of CSL Capital Management, L.P., an energy services-focused private equity fund. Following the redemption of the Public Shares, the conversion of the Public Warrants and the forfeiture of the Private Placement Warrants noted above, the only securities of the Company outstanding were the Founder Shares. The Founder Shares are identical to the shares of Class A common stock that were included in the Units sold in the Public Offering except that (1) holders of the Founder Shares have the right to vote on the election of directors prior to an initial business combination, (2) the Founder Shares are subject to certain transfer restrictions, as described in more detail below, (3) holders of the Founder Shares entered into letter agreements with the Company pursuant to which they agreed to waive their redemption rights with respect to any Founder Shares held by them in connection with the completion of an initial business combination, (4) the Founder Shares will automatically convert on a one-for-one basis into shares of Class A common stock at the time of an initial business combination and (5) the Founder Shares are subject to registration rights, as described below. In August 2017, the Sponsor surrendered 5,750,000 shares of its Class B common stock for no consideration to adjust its holdings to an expected 20% of the Company’s combined outstanding shares of Class A common stock and Class B common following the Public Offering, resulting in the Sponsor holding an aggregate of 8,625,000 Founder Shares. In October 2017 and April 2018, the Sponsor transferred 37,500 Founder Shares to Marc Zenner and Jon A. Marshall, respectively, both of whom were independent directors of the Company at the time, at the original purchase price. Each of the Sponsor and Messrs. Zenner and Marshall subsequently agreed to forfeit 90% of their Founder Shares when the Company was unable to consummate a business combination prior to the deadline in its Charter, resulting in the Sponsor currently holding 855,000 Founder Shares and each of Messrs. Zenner and Marshall owning 3,750 Founder Shares. As a result, the total number of Founder Shares outstanding as of September 30, 2021 is 862,500. Transfer Restrictions The terms applicable to the Founder Shares provide that, subject to limited exceptions, the Sponsor may not transfer, assign or sell any of the same until the earlier to occur of: (A) one year after the completion of the initial business combination or (B) subsequent to the initial business combination, (x) if the last sale price of the Company’s Class A common stock equals or exceeds $12.00 per share (as adjusted for share splits, 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 initial business combination, or (y) the date on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the Company’s stockholders having the right to exchange their common stock for cash, securities or other property. The Sponsor transferred the portion of its Founder Shares noted above to Messrs. Zenner and Marshall in accordance with those terms or pursuant to a waiver thereof. Registration Rights The holders of Founder Shares that may be issued equity securities of the Company upon conversion of working capital loans may be entitled to registration rights (in the case of the Founder Shares, only after conversion of such shares to shares of Class A common stock) pursuant to a registration rights agreement, by and between the Company, the Sponsor and Mr. Zenner. The registration rights include certain demand and “piggyback” rights. However, the registration rights agreement provides that the Company will not permit any registration statement filed under the Securities Act to become effective until termination of the applicable lock-up period for the securities to be registered. The Company will bear the expenses incurred in connection with the filing of any such registration statements. Advances from Related Parties During the three months ended September 30, 2021 and 2020, the Sponsor or an affiliate of the Sponsor incurred certain administrative expenses on behalf of the Company in the amount of $0 and $495, respectively. During the nine months ended September 30, 2021 and 2020, the Sponsor or an affiliate of the Sponsor incurred certain administrative expenses on behalf of the Company in the amount of $3,730 and $6,531, respectively. As of September 30, 2021 and December 31, 2020, the outstanding balance on the expenses paid on the Company’s behalf was $0 and $0, respectively. The Company repaid the $3,730 incurred in the nine months ended September 30, 2021 to the Sponsor using cash on hand. During the nine months ended September 30, 2020, the Sponsor advanced $1,832,134 to fund ongoing operations of the Company. These advances were due on demand and were non-interest bearing. During that same time period, the $4,211,777 outstanding in Sponsor advances, including the amount advanced in the nine months ended September 30, 2020, was converted into or treated as a capital contribution for which a total of 421,177 shares of Class A Common Stock of the Company was issued to the Sponsor at a conversion price of $10.00 per share. For additional information on the conversion and capital contribution, see Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations–Liquidity and Capital Resources. The Sponsor has made no subsequent advances. As of September 30, 2021 and December 31, 2020, the outstanding balance on the advances was $0. Promissory Note Payable - Sponsor On March 1, 2019, the Company issued a convertible promissory note (the “Convertible Promissory Note”) in the amount of up to $1,500,000 with the Sponsor to fund the Company’s ongoing expenses. The Convertible Promissory Note does not bear interest and all unpaid principal was due and payable in full on the earlier of November 7, 2019 or the consummation of an initial business combination by the Company. The Sponsor had the option to convert any amounts outstanding under the Convertible Promissory Note into warrants of a post-business combination entity to purchase shares, at a conversion price of $1.50 per warrant. On March 31, 2020, the Sponsor converted the $999,640 outstanding into 99,964 shares of Class A Common Stock of the Company at a conversion price of $10.00 per share. All unpaid principal under the Convertible Promissory Note was due and payable in full on the earlier of November 7, 2019 or the consummation of an initial business combination by the Company by the deadline specified in its Charter. As a result, the Convertible Promissory Note is no longer available to the Company as a source of financing and no amount has been outstanding thereunder since March 31, 2020. As of September 30, 2021 and December 31, 2020, the outstanding balance on Convertible Promissory Note was $0. Contributions from Related Party On May 15, 2020, the Sponsor paid $25,000 to the Company in exchange for the issuance of 2,500 shares of Class A common stock to the Sponsor. On August 7, 2020, the Sponsor paid a $197,687 capital contribution to the Company in exchange for the issuance of 19,769 shares of Class A common stock. On December 15, 2020, the Sponsor paid a $75,000 capital contribution to the Company in exchange for the issuance of 7,500 shares of Class A common stock. Together, these contributions during the fiscal year ended December 31, 2020 totaled $297,687, in exchange for which the Company issued 29,769 shares of Class A common stock to the Sponsor. As of December 31, 2020, there were 550,911 shares of the Company’s Class A common stock outstanding, all of which are held by our Sponsor. In May 2021, the Company received an advance of $35,000 from the Sponsor to fund ongoing operations and expenses. The amount advanced by the Sponsor was treated as a capital contribution in exchange for which the Company issued to the Sponsor 3,500 shares of the Company’s Class A common stock at $10.00 per share on May 3, 2021. Administrative Support Agreement Commencing on the date the Units were first listed on the Nasdaq Capital Market, the Company agreed to pay an affiliate of the Sponsor up to $10,000 per month for office space, utilities and secretarial and administrative support. Since the Company was unable to complete its initial business combination prior to the November 7, 2019 deadline in the Charter, pursuant to the Administrative Support Agreement, the Company ceased paying these monthly fees. The Administrative Support Agreement, however, remains in place for the benefit of the Company. The Company did not incur any expenses under the administrative service agreement for the three and nine months ended September 30, 2021 and 2020.

Accounting Policies, by Policy

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed financial statements of the Company are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the accounting and disclosure rules and regulations of the Securities and Exchange Commission (the “SEC”), and reflect all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the financial position as of September 30, 2021 and the results of operations and cash flows for the periods presented. Certain information and disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations. Interim results are not necessarily indicative of results for a full year. The accompanying unaudited condensed financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Annual Report on Form 10-K filed by the Company with the SEC on March 31, 2021.
Emerging Growth Company	Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the JOBS Act, and it 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, 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 stockholder 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 a 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 (i) not an emerging growth company or (ii) 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.
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 expenses during the reporting periods. Actual results could differ from those estimates.
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 credit limit of $250,000. At September 30, 2021 and 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.
Risks and Uncertainties	Risks and Uncertainties Management continues to evaluate the impact of the COVID-19 pandemic on the industry and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position and results of its operations, 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.
Financial Instruments	Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures
Cash and Cash Equivalents	Cash and Cash Equivalents
Net Loss Per Share of Common Stock	Net Loss Per Share of Common Stock Net loss per share of common stock is computed by dividing net loss applicable to the shares of common stock by the weighted average number of shares outstanding for the periods. As a result of the redemption of Public Shares in November 2019, for the three and nine months ended September 30, 2021 and 2020, the Class A shares have no specific redemption rights. As a result, net loss per common share is calculated by dividing the net loss by the weighted average number of Class A and Class B shares outstanding for the periods.
Income Taxes	Income Taxes The Company follows the asset and liability method of accounting for income taxes under FASB ASC Topic 740, Income Taxes FASB Topic ASC 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. There were no unrecognized tax benefits as of September 30, 2021 and December 31, 2020. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties at September 30, 2021 and 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 subject to income tax examinations by major taxing authorities since inception. The Company may be subject to potential examination by federal, state, and city taxing authorities in the areas of income taxes. These potential examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions, and compliance with federal, state, and city tax laws. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. During the three and nine months ended September 30, 2021 and 2020, the Company recorded income tax expense of $0.
Subsequent Events	Subsequent Events The Company evaluates subsequent events and transactions that occur after the balance sheet date for potential recognition or disclosure. Any material events that occur between the balance sheet date and the date that the unaudited condensed financial statements were issued are disclosed as subsequent events, while the unaudited condensed financial statements are adjusted to reflect any conditions that existed at the balance sheet date.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The Company’s management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have an effect on the Company’s financial statements.

The Charter and the prospectus that the Company filed in connection with the Public Offering provided that the Company had 24 months after the closing of its Public Offering, or until November 7, 2019, to complete a business combination. During the period since the Company’s Public Offering, the Company diligently searched for a business to combine with in a transaction that would generate value for the Company’s stockholders; however, over the same period, the energy sector experienced significant headwinds, which increased the challenges faced by the Company in sourcing a compelling target business.
