Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
ORGANIZATION AND DESCRIPTION OF BUSINESS | ORGANIZATION AND DESCRIPTION OF BUSINESS Energy Vault Holdings, Inc., which together with its subsidiaries is referred to herein as “Energy Vault” or the “Company”, is a grid-scale energy storage company that is driving a faster transition to more pervasive renewable power by solving the intermittence issues that are inherent to the most prevalent forms of renewable power, solar and wind. The Company’s mission is to provide energy storage solutions to accelerate the global transition to renewable energy. Energy Vault was originally incorporated under the name Novus Capital Corporation II (“Novus”) as a special purpose acquisition company in the state of Delaware in September 2020 with the purpose of effecting a merger with one or more operating businesses. On September 8, 2021, Novus announced that it had entered into a definitive agreement for a business combination (the “Merger Agreement”) with Energy Vault, Inc. (“Legacy Energy Vault”) that would result in Legacy Energy Vault becoming a wholly owned subsidiary of Novus (the “Merger”). Upon the closing of the Merger on February 11, 2022 (the “Closing”), Novus was immediately renamed to “Energy Vault Holdings, Inc.” The Merger between Novus and Legacy Energy Vault was accounted for as a reverse recapitalization in accordance with United States Generally Accepted Accounting Principles (“GAAP”). See Note 3 - Reverse Capitalization for more information. Throughout the notes to the consolidated condensed financial statements, unless otherwise noted, the “Company,” “we,” “us,” or “our” and similar terms refer to Legacy Energy Vault and its subsidiaries prior to the consummation of the Merger, and Energy Vault and its subsidiaries after the consummation of the Merger. |

Accounting Policies [Abstract] | |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements have been prepared on an accrual basis of accounting in accordance with GAAP and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2022. The condensed consolidated balance sheet as of December 31, 2022, included herein, was derived from the consolidated financial statements of the Company as of that date. These unaudited interim condensed consolidated financial statements, in the opinion of management, reflect all adjustments necessary to present fairly the Company’s financial position as of June 30, 2023 and the Company’s results of operations and comprehensive loss, convertible preferred stock and stockholders’ equity activities, and the cash flows for the three and six months ended June 30, 2023 and 2022. The results for the three and six months ended June 30, 2023 are not necessarily indicative of the results to be expected for the year ending December 31, 2023 or for any interim period or for any other future year. Principles of Consolidation These unaudited interim condensed consolidated financial statements include Energy Vault Holdings, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. If the Company has a variable interest in an entity, an assessment is performed to determine if that entity is a variable interest entity (“VIE”), and if so, if the Company is the primary beneficiary of the VIE. The assessment of whether an entity is a VIE requires an evaluation of qualitative factors and, where applicable, quantitative factors. These factors include: (i) determining whether the entity has sufficient equity at risk, (ii) evaluating whether the equity holders, as a group, lack the ability to make decisions that significantly affect the economic performance of the entity, and (iii) determining whether the entity is structured with disproportionate voting rights in relation to their equity interests. The Company has determined that it is not the primary beneficiary of any VIEs in which it has a variable interest as of June 30, 2023. Emerging Growth Company Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (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 consolidated 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. Use of Estimates The preparation of the condensed consolidated financial statements, in conformity with GAAP requires management to make estimates an d assumptions that affect the amounts reported in the unaudited interim condensed consolidated financial statements and accompanying notes. The Company evaluates its assumptions on an ongoing basis. The Company’s management believes that the estimates, judgment, and assumptions used are reasonable based upon information available at the time they are made. Significant estimates made by management include, among others, revenue recognition, stock-based compensation, and valuation of warrant liability. Due to the inherent uncertainty invol ved in making assumptions and estimates, changes in circumstances could result in actual results differing from those estimates, and such differences could be material to the Company’s consolidated financial condition and results of operations. Segment Reporting The Company reports its operating results and financial information in one operating and reportable segment. Our chief operating decision maker, which is our chief executive officer, reviews our operating results on a consolidated basis and uses that consolidated financial information to make operating decisions, assess financial performance, and allocate resources. Concentration of Credit Risk Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, accounts receivable, and customer financings receivable. Risks associated with cash and cash equivalents and restricted cash are mitigated by banking with creditworthy institutions. Such balances with any one institution may, at times, be in excess of federally insured amounts.

Reverse Recapitalization [Abstract] | |
REVERSE RECAPITALIZATION | REVERSE RECAPITALIZATION On February 11, 2022, in connection with the Merger, the Company raised gross proceeds of $235.9 million , including the contribution of $40.9 million of cash, net of redemptions, held in Novus’ trust account from its initial public offering and an aggregate purchase price of $195.0 million from the sale and issuance of common shares in a private placement (“Private Investment in Public Equity” or “PIPE”) at $10.00 per share. The Company and Novus incurred in aggregate approximately $44.8 million in transaction costs, consisting of underwriting, legal, and other professional fees, of which $24.2 million was recorded to additional paid-in-capital as a reduction of proceeds and the remaining $20.6 million was expensed immediately upon the Closing. The aggregate consideration paid to Legacy Energy Vault stockholders in connection with the Merger (excluding any potential Earn-Out Shares), was 106.2 million shares of the Company’s common stock, par value $0.0001 after giving effect to the exchange ratio of 6.7735 (the “Exchange Ratio”). The total net cash proceeds to the Company were $191.1 million. The following transactions were completed as part of the Merger: • All issued and outstanding shares of Legacy Energy Vault convertible preferred stock were canceled and c onverted into a total of 85.7 million shares of Energy Vault common stock; • Each issued and outstanding share of Legacy Energy Vault common stock was canceled and converted into a total of 20.4 million shares of Energy Vault common stock; • Each outstanding vested and unvested Legacy Energy Vault common stock option was converted into options exercisable for shares of Energy Vault common stock with the same terms except for the number of shares exercisable and the exercise price, each of which was adjusted by the Exchange Ratio; • Each outstanding and unvested Legacy Energy Vault restricted stock unit (“RSU”) was converted into RSUs for shares of Energy Vault common stock with the same terms except for the number of shares, each of which was adjusted by the Exchange Ratio; and • Each outstanding vested and unvested Legacy Energy Vault restricted stock award (“RSA”) was converted into RSAs for shares of Energy Vault common stock with the same terms except for the number of shares, each of which was adjusted by the Exchange Ratio. The Merger was accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, Novus was treated as the acquired company for financial reporting purposes. The reverse recapitalization accounting treatment was primarily determined based on the shareholders of Legacy Energy Vault having a relative majority of the voting power of Energy Vault and having the ability to nominate the majority of the members of the Energy Vault Board, senior management of Legacy Energy Vault comprise the senior management of Energy Vault, and the operations of Legacy Energy Vault prior to the Merger comprise the ongoing operations of Energy Vault. Accordingly, for accounting purposes, the financial statements of the combined entity upon completion of the Merger represent a continuation of the financial statements of Legacy Energy Vault with the Merger being treated as the equivalent of Legacy Energy Vault issuing shares for the net assets of Novus, accompanied by a recapitalization. The net assets of Novus were recognized at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Merger are presented as those of Legacy Energy Vault and the accumulated deficit of Legacy Energy Vault has been carried forward after Closing. All periods prior to the Merger have been retroactively adjusted using the Exchange Ratio for the equivalent number of shares outstanding immediately after the Closing to effect the reverse recapitalization. The number of shares of common stock issued following the consummation of the Merger was as follows (in thousands): Shares Legacy Energy Vault stock (1) 106,172 Novus public shares (2) 4,079 Novus sponsor shares (3) 3,975 PIPE shares 19,500 Total shares of Energy Vault common stock issued as part of the Merger 133,726 __________________ (1) Excludes 9.0 million common shares issuable in earn-out arrangements as they are not issuable until 90 days after the Closing and are contingently issuable based upon the Company’s share price meeting certain thresholds. (2) Excludes 14.7 million warrants issued and outstanding as of the Closing of the Merger which includes 9.6 million public warrants and 5.2 million private warrants held by the Novus Sponsor. |

The Company utilizes a probability-of-default (“PD”) and loss-given-default (“LGD”) methodology to calculate the allowance for expected credit losses for each customer by type of financial asset. Due to the Company’s limited operating history and lack of loss history, the Company derived its PD and LGD rates using average historical rates for corporate bonds as published by Moody’s. The Company uses PD and LGD rates that correspond to the customer’s credit rating and period of time in which the financial asset is expected to remain outstanding. |

FAIR VALUE MEASUREMENTS | FAIR VALUE MEASUREMENTS Carrying amounts of certain financial instruments, including cash, accounts payable, and accrued liabilities approximate their fair value due to their relatively short maturities and market interest rates, if applicable. The Company categorizes assets and liabilities recorded or disclosed at fair value on the consolidated balance sheet based upon the level of judgment associated with inputs used to measure their fair value. The categories are as follows: • Level 1 —Inputs which included quoted prices in active markets for identical assets and liabilities. • Level 2 —Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 —Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. The Company’s financial assets and liabilities measured at fair value on a recurring basis were as follows as of June 30, 2023 and December 31, 2022, respectively (amounts in thousands): Level 1 Level 2 Level 3 Total Assets (Liabilities): Derivative asset — conversion option (1) $ — $ — $ 1,025 $ 1,025 Warrant liability (2) — — (2) (2) __________________ (1) Refer to Note 8 - Convertible Note Receivable for further information.

Receivables [Abstract] | |
CONVERTIBLE NOTE RECEIVABLE | CONVERTIBLE NOTE RECEIVABLE In October 2021, the Company entered into a convertible promissory note purchase agreement with DG Fuels, LLC (“DG Fuels”) and purchased a promissory note with a principal balance of $1.0 million (“DG Fuels Tranche 1 Note”). In April 2022, the Company purchased an additional promissory note from DG Fuels with a principal balance of $2.0 million. (“DG Fuels Tranche 2 Note”) (collectively, the “DG Fuels Note”). The convertible promissory note is recorded in other assets in the condensed consolidated balance sheets. The maturity date of the DG Fuels Note is the earlier of (i) 30 days after a demand for payment is made by the Company at any time after the two year anniversary of the date of issuance of the note; (ii) the four year anniversary of the date of issuance of the note; (iii) five days following a Financial Close (“Financial Close” means a project finance style closing by DG Fuels or its subsidiary of debt and equity capital to finance the construction of that certain biofuel facility currently under development by DG Fuels), or (iv) upon an event of default determined at the discretion of the Company. The DG Fuels Note has an annual interest rate of 10.0%. The Company intends to hold and convert the DG Fuels Note into the equity securities issued by DG Fuels in its next equity financing round that is greater than $20.0 million at a 20% discount to the issuance price. The principal balance and unpaid accrued interest on the DG Fuels Note will, at the option of the Company, convert into equity securities upon the closing of such next equity financing round. The discounted conversion rate in the DG Fuels Note is considered a redemption feature that is an embedded derivative, which requires bifurcation and separate accounting at its estimated fair value under ASC 815 – Derivative and Hedging . The embedded derivative upon the purchase of the DG Fuels Tranche 1 Note was an asset of $0.4 million and the embedded derivative upon the purchase of the DG Fuels Tranche 2 note was an asset of $0.7 million. The estimated fair value of the derivative instruments was recognized as a derivative asset on the condensed consolidated balance sheets, with an offsetting discount to the DG Fuels Note. The Company amortizes the discount on the Note into interest income using the effective interest method. The Company recognized interest income from the DG Fuels Note of $0.1 million and $0.2 million for the three and six months ended June 30, 2023 and $0.1 million for the three and six months ended June 30, 2022. Interest income related to the amortization of the debt discount was $50 thousand and $0.1 million for the three and six months ended June 30, 2023 and $22 thousand and $30 thousand for the three and six months ended June 30, 2022, respectively. At each reporting period, the Company remeasures this derivative financial instrument to its estimated fair value. The change in the estimated fair value is recorded in other income, net in the consolidated statement of operations and comprehensive loss. For the three and six months ended June 30, 2023 and 2022, ther e was no change in the fair value of th e embedded derivative. A reconciliation of the beginning and ending asset balance for the embedded derivative in the DG Fuels Note is as follows (amounts in thousands): Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 Beginning of period $ 1,025 $ 350 $ 1,025 $ 350 Additions — 675 — 675 Change in fair value — — — — End of period $ 1,025 $ 1,025 $ 1,025 $ 1,025 The Company has determined that DG Fuels is a variable interest entity and that the Company has a variable interest in it through the DG Fuels note. The Company is not the primary beneficiary of DG Fuels, and thus is not required to consolidate DG Fuels. The Company’s maximum exposure to loss related to DG Fuels is limited to the Company’s investment of $3.0 million. |

Equity [Abstract] | |
WARRANTS | WARRANTS Upon the Closing of the Merger, the Company assumed 9.6 million Public Warrants and 5.2 million Private Warrants. Each whole warrant entitled the holder to purchase one share of the Company’s common stock at an exercise price of $11.50 per share, subject to adjustments. The warrants became exercisa ble on March 13, 2022, and at that time were scheduled to expire on February 11, 2027, which represents five years after the Closing. The Company filed a Registration Statement on Form S-1 on March 8, 2022, related to the issuance of an aggregate of up to approximately 14.7 million shares of common stock issuable upon the exercise of the Public and Private Warrants, which was declared effective by the SEC on May 6, 2022. All Public Warrants were exercised or redeemed during 2022. There were no Public Warrants outstanding as of June 30, 2023 and December 31, 2022. There has not been any Private Warrant activity since the Closing of the Merger and there were 5.2 million Private Warrants outstanding as of June 30, 2023, December 31, 2022, and June 30, 2022. The following table summarizes the Public Warrant activity for the three and six months ended June 30, 2022 (in thousands): Three Months Ended June 30, 2022 Six Months Ended June 30, 2022 Number of Public Warrants at beginning of period 9,583 — Warrants assumed upon Closing of Merger — 9,583 Warrants exercised (683) (683) Number of Public Warrants at end of period 8,900 8,900 The Public Warrants were classified as Level 1 measurements from the Closing of the Merger through the date they were redeemed as the Public Warrants had an adequate trading volume to provide reliable indication of value. The Private Warrants were classified as Level 2 from the Closing of the Merger through the Public Warrant redemption date of August 1, 2022 because the Private Warrants had similar terms to the Public Warrants. Upon the ceasing of trading of the Public Warrants on August 1, 2022, the fair value measurement of the Private Warrants transferred from Level 2 to Level 3 and the Company uses a Black Scholes model to determine the fair value of the Private Warrants. The primary significant unobservable input used to evaluate the fair value measurement of the Company’s Private Warrants is the expected volatility. A significant increase in the expected volatility in isolation would result in a significantly higher fair value measurement. The Private Warrants were val ued at less than $0.01 per warrant a s of June 30, 2023. As of June 30, 2023 and December 31, 2022, the Company’s warrant liability for its Private Warrants was $2 thousand.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies) | 6 Months Ended |
Jun. 30, 2023 | |
Accounting Policies [Abstract] | |
Basis of Presentation | Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements have been prepared on an accrual basis of accounting in accordance with GAAP and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2022. The condensed consolidated balance sheet as of December 31, 2022, included herein, was derived from the consolidated financial statements of the Company as of that date. These unaudited interim condensed consolidated financial statements, in the opinion of management, reflect all adjustments necessary to present fairly the Company’s financial position as of June 30, 2023 and the Company’s results of operations and comprehensive loss, convertible preferred stock and stockholders’ equity activities, and the cash flows for the three and six months ended June 30, 2023 and 2022. The results for the three and six months ended June 30, 2023 are not necessarily indicative of the results to be expected for the year ending December 31, 2023 or for any interim period or for any other future year. |
Principles of Consolidation | Principles of Consolidation These unaudited interim condensed consolidated financial statements include Energy Vault Holdings, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. If the Company has a variable interest in an entity, an assessment is performed to determine if that entity is a variable interest entity (“VIE”), and if so, if the Company is the primary beneficiary of the VIE. The assessment of whether an entity is a VIE requires an evaluation of qualitative factors and, where applicable, quantitative factors. These factors include: (i) determining whether the entity has sufficient equity at risk, (ii) evaluating whether the equity holders, as a group, lack the ability to make decisions that significantly affect the economic performance of the entity, and (iii) determining whether the entity is structured with disproportionate voting rights in relation to their equity interests. The Company has determined that it is not the primary beneficiary of any VIEs in which it has a variable interest as of June 30, 2023. |
Use of Estimates | Use of Estimates The preparation of the condensed consolidated financial statements, in conformity with GAAP requires management to make estimates an d assumptions that affect the amounts reported in the unaudited interim condensed consolidated financial statements and accompanying notes. The Company evaluates its assumptions on an ongoing basis. The Company’s management believes that the estimates, judgment, and assumptions used are reasonable based upon information available at the time they are made. Significant estimates made by management include, among others, revenue recognition, stock-based compensation, and valuation of warrant liability. Due to the inherent uncertainty invol ved in making assumptions and estimates, changes in circumstances could result in actual results differing from those estimates, and such differences could be material to the Company’s consolidated financial condition and results of operations. |
Segment Reporting | Segment ReportingThe Company reports its operating results and financial information in one operating and reportable segment. Our chief operating decision maker, which is our chief executive officer, reviews our operating results on a consolidated basis and uses that consolidated financial information to make operating decisions, assess financial performance, and allocate resources. |
Concentration of Credit Risk | Concentration of Credit Risk Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, accounts receivable, and customer financings receivable. |
Recently Adopted Accounting Pronouncements | Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . ASU 2016-13 amended the impairment model to improve financial reporting by requiring earlier recognition of credit losses on certain financial assets. This standard replaces the previous incurred loss impairment model that recognized losses when a probable threshold was met, with a requirement to recognize lifetime expected credit |
