Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business and Basis of Presentation	Nature of Business and Basis of Presentation Description of Business Hyzon Motors Inc. (“Hyzon” or the “Company”), headquartered in Honeoye Falls, New York, is commercializing its proprietary heavy-duty fuel cell technology through manufacturing and retrofitting heavy-duty hydrogen fuel cell electric vehicles (“FCEVs”) in the United States, Europe, and Australia. In addition, Hyzon builds and fosters a clean hydrogen supply ecosystem with leading partners from feedstocks through production, dispensing, and financing. The Company is majority-owned by Hymas Pte. Ltd. (“Hymas”), a Singapore company, which is majority-owned but indirectly controlled by Horizon Fuel Cell Technologies PTE Ltd., a Singapore company (“Horizon”). Business Combination and Basis of Presentation The accompanying unaudited interim consolidated financial statements and related disclosures have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) pursuant to the requirements and rules of the SEC regarding interim reporting. Certain notes or other information that are normally required by U.S. GAAP have been omitted if they substantially duplicate the disclosures contained in the Company’s annual audited consolidated financial statements. Accordingly, the unaudited interim consolidated financial statements should be read in connection with the Company’s audited consolidated financial statements and related notes included in the Company’s amended Annual Report filed on Form 10-K/A for the year ended December 31, 2021. The Company’s unaudited interim consolidated financial statements include the accounts and operations of the Company and its wholly owned subsidiaries including variable interest entity arrangements in which the Company is the primary beneficiary. All intercompany accounts and transactions are eliminated in consolidation. In the opinion of management, the accompanying unaudited interim consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation for the periods presented. Results of operations reported for interim periods presented are not necessarily indicative of results for the entire year or any other periods. On July 16, 2021 (the “Closing Date”), legacy Hyzon Motors Inc. and now named Hyzon Motors USA Inc., (“Legacy Hyzon”), consummated the transactions contemplated by the Business Combination Agreement and Plan of Reorganization (the “Business Combination”), dated February 8, 2021, with Decarbonization Plus Acquisition Corporation (“DCRB”) to effect a business combination between DCRB and Legacy Hyzon with DCRB Merger Sub Inc., a wholly owned subsidiary of DCRB, merging with and into Legacy Hyzon, with Legacy Hyzon surviving the merger as a wholly owned subsidiary of DCRB. On the Closing Date, DCRB changed its name to “Hyzon Motors Inc.” and Legacy Hyzon changed its name to “Hyzon Motors USA Inc.” The Business Combination was accounted for as a reverse recapitalization in accordance with U.S. GAAP, with no goodwill or other intangible assets recorded and the net assets of Legacy Hyzon consolidated with DCRB at historical cost. Under this method of accounting, DCRB is treated as the “acquired” company for financial reporting purposes. Accordingly, the equity structure has been retrospectively adjusted in all comparative periods up to the Closing Date, to reflect the number of shares of the Company's common stock, $0.0001 par value per share issued to Legacy Hyzon's stockholders in connection with the reverse recapitalization. As such, the shares and corresponding capital amounts and earnings per share related to Legacy Hyzon common stock prior to the Business Combination have been retroactively restated as shares reflecting an exchange ratio of 1.772 (the “Exchange Ratio”). Liquidity The Company generated net income of $38.8 million and $30.0 million for the three and six months ended June 30, 2022, respectively. The Company incurred net losses of $9.7 million and $18.1 million for the three and six months ended June 30, 2021, respectively. Retained earnings amounted to $9.1 million and accumulated deficit amounted to $26.4 million as of June 30, 2022 and December 31, 2021, respectively. Net cash used in operating activities was $68.9 million and $19.5 million for the six months ended June 30, 2022 and 2021, respectively. On July 16, 2021, the Company received $509.0 million in cash, net of redemption and transaction costs as a result of the Business Combination. As of June 30, 2022, the Company has $363.9 million in unrestricted cash and cash equivalents and $5.0 million in restricted cash. Restricted cash is pledged as security for letters of credit or other collateral amounts established by the Company for certain lease obligations, corporate credit cards, and other contractual arrangements. The Company’s restricted cash is included within Other assets in the unaudited interim Consolidated Balance Sheets. As an early stage growth company, the Company expects to continue to incur net losses in the near term. As the Company commenced its internal restructuring effort in 2022, the primary focuses are the advancement of its proprietary fuel cell technology and development and commercialization of single heavy duty commercial vehicle platform in each region by leveraging third party contracted manufacturers. Until the Company can generate sufficient revenue from product sales, retrofit services or lease arrangements to cover operating expenses, working capital and capital expenditures, the Company will need to raise additional capital. The Company expects to fund cash needs through a combination of equity and debt financing, including lease securitization, strategic collaborations, and licensing arrangements. If the Company cannot raise additional funds when needed, our financial condition, business, prospects, and results of operations could be materially adversely affected. These financial statements have been prepared by management in accordance with U.S. GAAP and this basis assumes that the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. These financial statements do not include any adjustments that may result from the outcome of this uncertainty. As of the date of this Quarterly Report on Form 10-Q, management believes that the Company’s existing financial resources will be sufficient to execute its operating priorities for the next 12 months following the issuance date of these unaudited interim financial statements. As of March 31, 2023, unrestricted cash, cash equivalents, and short-term investments were approximately $210 million. Risks and Uncertainties The Company is subject to a variety of risks and uncertainties common to early-stage companies with a history of losses and are expected to incur significant expenses and continuing losses for the foreseeable future. The risks and uncertainties include, but not limited to, further development of its technology, marketing and distribution channels, further development of its supply chain and manufacturing, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, and the ability to secure additional capital to fund operations. Reclassifications Certain items previously reported in specific financial statement captions have been reclassified to conform to the current presentation in the consolidated financial statements and the accompanying notes.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue The Company recognized negligible revenue and $2.9 million in sales of hydrogen fuel cell systems in the United States, sales of FCEVs in China, and retrofit services in Europe for the three and six months ended June 30, 2022, respectively. The Company did not recognize any revenue for the three and six months ended June 30, 2021. In accordance with ASC 606, the Company is required to evaluate customers’ ability and intent to pay substantially all of the consideration to which the Company is entitled in exchange for the vehicles transferred to the customer, i.e., collectability of contracts with customers. The customer in China, to which the Company delivered 62 FCEVs in 2021, is a special purpose entity established in response to China’s national hydrogen fuel cell vehicle pilot program. While in the Company’s estimation the customer has strong business plans and management teams, in consideration of the customer’s limited operating history and extended payment terms in their contracts, the Company determined the collectability criterion is not met with respect to contract existence under ASC 606, and therefore, an alternative method of revenue recognition has been applied to the arrangement. The $2.5 million of revenue recognized under this arrangement in the six months ended June 30, 2022 is equal to the remaining consideration received after satisfying local government VAT obligations, as such amounts are non-refundable and the Company has transferred control of the 62 FCEVs to which the consideration relates and has stopped transferring goods or services to the customer. The Company will continue to monitor the customer and evaluate the collectability criterion as of each reporting period. The total cost of FCEVs delivered to the customer in China was recorded within Cost of revenue in the Consolidated Statements of Operations and Comprehensive Income (Loss) in 2021 since control of such FCEVs was transferred to the customer prior to December 31, 2021. Contract Balances Contract liabilities relate to the advance consideration invoiced or received from customers for products and services prior to satisfying a performance obligation or in excess of amounts allocated to a previously satisfied performance obligation. The current portion of contract liabilities is recorded within Contract liabilities in the Consolidated Balance Sheets and totaled $2.1 million and $10.9 million as of June 30, 2022 and December 31, 2021, respectively. The long-term portion of contract liabilities is recorded within Other liabilities in the Consolidated Balance Sheets and totaled $6.0 million and $1.0 million as of June 30, 2022 and December 31, 2021, respectively. As part of efforts to exit certain customer contracts, the Company refunded $1.3 million to customers in the third and fourth quarters of 2022. Remaining Performance Obligations

Investments, Debt and Equity Securities [Abstract]
Investments in Equity Securities	Investments in Equity Securities The Company owns common shares, participation rights, and options to purchase additional common shares in certain private companies. On a non-recurring basis, the carrying value is adjusted for changes resulting from observable price changes in orderly transactions for identical or similar investments in the same issuer or an impairment. Included in Gain (loss) on equity securities in the unaudited interim Consolidated Statements of Operations and Comprehensive Income (Loss) for the six months ended June 30, 2022 is a $12.5 million gain related to the equity investment in Raven SR, Inc. (“Raven”). The investment in Raven’s common shares and options were initially accounted for at cost of $2.5 million. In March 2022, there was an observable change in price of Raven’s common shares. The change in observable price of Raven’s common shares also results in a remeasurement of the investment in Raven’s options as of the date that the observable transaction took place. The fair value of the investment in Raven’s common shares was determined based on observable market prices of identical instruments in less active markets and is classified accordingly as Level 2 in the fair value hierarchy. Due to certain anti-dilution rights included in the options held by the Company, the fair value was determined utilizing a Monte-Carlo simulation model. Accordingly, this was determined to be a Level 3 measurement in the fair value hierarchy. The most significant assumptions in the model included the transaction price of the underlying common shares at the transaction date, expected volatility, risk free rate, and certain assumptions around the likelihood, size, and timing of potential future equity raises by Raven. As of March 31, 2022, the period end in which the observable change in price occurred, the Company determined the fair value of the investment in Raven’s common shares and options to be $6.5 million and $8.5 million, respectively. Additionally, included in Gain (loss) on equity securities in the unaudited interim Consolidated Statements of Operations and Comprehensive Income (Loss) for the three and six months ended June 30, 2022 is a $2.4 million impairment loss related to the Company’s investment in Global NRG H2 Limited (“NRG”), a New Zealand corporation, equal to the initial cost basis. In accordance with ASC 321, Investments - Equity Securitie s (“ASC 321”), the investment in NRG does not have a readily determinable fair value and is measured at cost minus impairment, which requires the Company to evaluate on an ongoing basis whether an investment has been impaired based on qualitative factors. The Company impaired NRG due to the investee’s lack of progress in developing its plans and operating performance. The following table summarizes the total carrying value of held securities, measured as the total initial cost plus cumulative net gain (loss) (in thousands): June 30, December 31, Total initial cost basis $ 4,948 $ 4,948 Adjustments: Cumulative unrealized gain 12,530 — Cumulative impairment (2,448) — Carrying amount, end of period $ 15,030 $ 4,948 The following table summarizes unrealized gain and impairment recorded in Other income (expense) in the unaudited Consolidated Statements of Operations and Comprehensive Income (Loss), which are included as adjustments to the carrying value of equity securities (in thousands): Three Months Ended Six Months Ended 2022 2021 2022 2021 Unrealized gain on equity securities $ — $ — $ 12,530 $ — Cumulative impairment (2,448) — (2,448) — Total unrealized gain and impairment on equity securities $ (2,448) $ — $ 10,082 $ —

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the six months ended June 30, 2022, the Company recorded a net discrete tax expense of $0.5 million primarily associated with the establishment of a deferred tax liability that is not expected to offset available deferred tax assets. The Company did not record a provision for income taxes for the three months ended June 30, 2022, because the Company generated tax losses. The Company did not record a provision for income taxes for the three and six months ended June 30, 2021 because the Company generated tax losses. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company assesses all available evidence, both positive and negative, to determine the amount of any required valuation allowance within each taxing jurisdiction. Full valuation allowances have been established for the Company’s operations in all jurisdictions. As of June 30, 2022, and December 31, 2021, the Company had net deferred tax assets of approximately $31.8 million and $23.0 million, respectively, each of which was fully offset by a valuation allowance.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company follows the guidance in ASC 820, Fair Value Measurement . For assets and liabilities measured at fair value on a recurring and nonrecurring basis, a three-level hierarchy of measurements based upon observable and unobservable inputs is used to arrive at fair value. The Company uses valuation approaches that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels: • Level 1 inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. • Level 2 inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. • Level 3 inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date. As of June 30, 2022, and December 31, 2021, the carrying amount of accounts receivable, prepaid expenses and other current assets, accounts payable, and accrued liabilities approximate estimated fair value due to their relatively short maturities. The following tables present information about the Company’s assets and liabilities that are measured at fair value on a recurring basis and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value (in thousands): As of June 30, 2022 Level 1 Level 2 Level 3 Total Assets: Cash equivalents $ 100,000 $ — $ — $ 100,000 Liabilities: Warrant liability – Private Placement Warrants $ — $ 5,290 $ — $ 5,290 Earnout shares liability — — 34,424 34,424 As of December 31, 2021 Level 1 Level 2 Level 3 Total Liabilities: Warrant liability – Private Placement Warrants $ — $ 15,228 $ — $ 15,228 Earnout shares liability — — 103,761 103,761 Cash Equivalents The Company’s cash equivalents consist of short-term, highly liquid financial instruments that are readily convertible to cash with original maturities of three months or less. As of June 30, 2022, the Company has $100.0 million invested in money market funds. Earnout to Common Stockholders The fair value of the earnout shares was estimated by utilizing a Monte-Carlo simulation model. The inputs into the Monte-Carlo pricing model included significant unobservable inputs. The following table provides quantitative information regarding Level 3 fair value measurement inputs: June 30, December 31, Stock price $ 2.94 $ 6.49 Risk-free interest rate 3.0 % 1.2 % Volatility 95.0 % 90.0 % Remaining term (in years) 4.04 4.54 The following table presents the changes in the liabilities for Private Placement Warrants and Earnout for the six months ended June 30, 2022 (in thousands): Private Placement Warrants Earnout Balance as of December 31, 2021 $ 15,228 $ 103,761 Change in estimated fair value (9,938) (69,337) Balance as of June 30, 2022 $ 5,290 $ 34,424 The Company performs routine procedures such as comparing prices obtained from independent sources to ensure that appropriate fair values are recorded.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Proceedings The Company is subject to, and may become a party to, a variety of litigation, other claims, suits, indemnity demands, regulatory actions, and government investigations and inquiries in the ordinary course of business. The assessment as to whether a loss is probable or reasonably possible, and as to whether such loss or a range of such loss is estimable, often involves significant judgment about future events, and the outcome of litigation is inherently uncertain. The Company accrues for matters when we believe that losses are probable and can be reasonably estimated. As the outcome of individual matters is not predictable with assurance, the assessments are based on the Company’s knowledge and information available at the time; thus, the ultimate outcome of any matter could require payment substantially in excess of the amount being accrued and/or disclosed. The Company is party to current legal proceedings as discussed more fully below. Shareholder Securities and Derivative Litigation Three related putative securities class action lawsuits were filed between September 30, 2021 and November 15, 2021, in the U.S. District Court for the Western District of New York against the Company, certain of the Company’s current and former officers and directors and certain former officers and directors of DCRB (Kauffmann v. Hyzon Motors Inc., et al. (No. 21- cv-06612-CJS), Brennan v. Hyzon Motors Inc., et al. (No. 21-cv-06636-CJS), and Miller v. Hyzon Motors Inc. et al. (No. 21-cv-06695-CJS)), asserting violations of federal securities laws. The complaints generally allege that the Company and individual defendants made materially false and misleading statements relating to the nature of the Company’s customer contracts, vehicle orders, and sales and earnings projections, based on allegations in a report released on September 28, 2021, by Blue Orca Capital, an investment firm that indicated that it held a short position in the Company’s stock and which has made numerous allegations about the Company. These lawsuits have been consolidated under the caption In re Hyzon Motors Inc. Securities Litigation (Case No. 6:21-cv-06612-CJS-MWP), and on March 21, 2022, the court-appointed lead plaintiff filed a consolidated amended complaint seeking monetary damages. The Company and individual defendants moved to dismiss the consolidated amended complaint on May 20, 2022, and the court-appointed lead plaintiff filed its opposition to the motion on July 19, 2022. The court-appointed lead plaintiff filed an amended complaint on March 21, 2022, and a second amended complaint on September 16, 2022. Briefing regarding the Company and individual defendants’ anticipated motion to dismiss the second amended complaint has been stayed pending a scheduled, non-binding mediation among the parties. There is no assurance that the mediation will proceed as scheduled, or that, if mediation occurs, any or all parties will reach a settlement. Between December 16, 2021, and January 14, 2022, three related shareholder derivative lawsuits were filed in the U.S. District Court for the Western District of New York (Lee v. Anderson et al. (No. 21-cv-06744-CJS), Révész v. Anderson et al. (No. 22-cv-06012-CJS), and Shorab v. Anderson et al. (No. 22-cv-06023-CJS)). These three lawsuits have been consolidated under the caption In re Hyzon Motors Inc. Derivative Litigation (Case No. 6:21-cv-06744-CJS). On February 2, 2022, a similar shareholder derivative lawsuit was filed in the U.S. District Court for the District of Delaware (Yellets v. Gu et al. (No. 22-cv-00156)). On February 3, 2022, a similar shareholder derivative lawsuit was filed in the Supreme Court of the State of New York, Kings County (Ruddiman v. Anderson et al. (No. 503402/2022)). On February 13, 2023, a similar shareholder derivative lawsuit was filed in the Delaware Court of Chancery (Kelley v. Knight et al. (C.A. No. 2023-0173)). These lawsuits name as defendants the Company’s current and former directors and certain former directors of DCRB, along with the Company as a nominal defendant, and generally allege that the individual defendants breached their fiduciary duties by making or failing to prevent the misrepresentations alleged in the consolidated securities class action, and assert claims for violations of federal securities laws, breach of fiduciary duties, unjust enrichment, abuse of control, gross mismanagement, and/or waste of corporate assets. These lawsuits generally seek equitable relief and monetary damages. With the exception of the recently filed action in the Delaware Court of Chancery, each of the shareholder derivative actions has been stayed or the parties have jointly requested that it be stayed pending a decision regarding the anticipated motion to dismiss in the consolidated securities class action. On March 18, 2022, a putative class action complaint, Malork v. Anderson et al. (C.A. No. 2022-0260- KSJM), was filed in the Delaware Court of Chancery against certain officers and directors of DCRB, DCRB’s sponsor, and certain investors in DCRB’s sponsor, alleging that the director defendants and controlling shareholders of DCRB’s sponsor breached their fiduciary duties in connection with the merger between DCRB and Legacy Hyzon. The complaint seeks equitable relief and monetary damages. On May 26, 2022, the defendants in this case moved to dismiss the complaint. On August 2, 2022, the plaintiff filed an amended complaint. Defendants filed a motion to dismiss the amended complaint on August 15, 2022. Between January 26, 2022 and August 22, 2022, Hyzon received demands for books and records pursuant to Section 220 of the Delaware General Corporation Law from four stockholders who state they are investigating whether to file similar derivative or stockholder lawsuits, among other purposes. On May 31, 2022, one of these four stockholders represented that he had concluded his investigation and did not intend to file a complaint. On November 18, 2022, a second of the four stockholders filed a lawsuit in the Delaware Court of Chancery (Abu Ghazaleh v. Decarbonization Plus Acquisition Sponsor, LLC et al. (C.A. No. 2022-1050)), which was voluntarily dismissed shortly thereafter on December 1, 2022. On February 13, 2023, a third of these four shareholders filed a derivative lawsuit in the Delaware Court of Chancery (Kelley v. Knight et al. (C.A. No. 2023-0173)). The complaint asserts claims for breach of fiduciary duty and generally alleges that the individual defendants breached their fiduciary duties by making or failing to prevent misrepresentations including those alleged in the consolidated securities class action and the report released by Blue Orca Capital. As with the previously filed shareholder derivative lawsuits, the complaint seeks equitable relief and monetary damages. On April 18, 2023, the Company received a demand for books and records pursuant to Section 220 of the Delaware General Corporation Law from a stockholder seeking to investigate possible breaches of fiduciary duty or other misconduct or wrongdoing by the Company's controlling stockholder, Hymas Pte. Ltd. ("Hymas"), Hyzon's board of directors (the "Board") and/or certain members of Hyzon's senior management team in connection with the Company's entrance into (i) an equity transfer agreement (the "Equity Transfer") with certain entities affiliated with the Company, and (ii) the share buyback agreement with the Hymas (the "Share Buyback" and, together with the Equity Transfer, the "Transactions") as reported by the Company in its Form 8-K filed on December 28, 2022. The above proceedings are subject to uncertainties inherent in the litigation process. The Company cannot predict the outcome of these matters or estimate the possible loss or range of possible loss, if any at this time. Government Investigations On January 12, 2022, the Company received a subpoena from the SEC for production of documents and information, including documents and information related to the allegations made in the September 28, 2021 report issued by Blue Orca Capital. The Company received two additional subpoenas in connection with the SEC’s investigation on August 5, 2022 and August 10, 2022. On October 31, 2022, the U.S. Attorney’s Office for the Southern District of New York (“SDNY”) notified the Company that it is also investigating these matters. The Company is cooperating and will continue to cooperate with these and any other regulatory or governmental investigations or inquiries. The Company cannot predict the ultimate outcome of the SEC and the SDNY investigations or inquiries. It is not possible to accurately predict at this time when matters will be completed, the final outcome as a result of those investigations or inquiries, what if any actions may be taken by the SEC or the SDNY, or the effect that such actions may have on our business, prospects, operating results and financial condition, which could be material. Customer and Supplier Dispute From time to time, the Company is subject to various commercial disputes or claims with its customers or suppliers. In January 2023, Duurzaam Transport B.V. and H2 Transport B.V., both private limited companies in the Netherlands and customers of the Company’s European subsidiary, Hyzon Motors Europe B.V. (“Hyzon Europe”), filed an attachment with the local Dutch court. The initial attachment claimed that Hyzon Europe was liable for liquidated and consequential damages stemming from Hyzon Europe allegedly not delivering trucks as contracted. The initial attachment placed a lien on the assets of Hyzon Europe. Following the attachments, Duurzaam Transport B.V. and H2 Transport B.V. initiated proceedings on the merits in February 2023. Eventually, the dispute was settled without any party admitting liability, and the Company made a payment of €2.1 million (approximately $2.2 million in USD) in April 2023 . Regardless of outcome, such proceedings or claims can have an adverse impact on the Company because of legal defense and settlement costs, the Company’s obligations to indemnify third parties, diversion of resources, and other factors, and there can be no assurances that favorable outcomes will be obtained. Based on the early-stage nature of these cases, the Company cannot predict the outcome of these currently outstanding customer and supplier dispute matters or estimate the possible loss or range of possible loss, if any.

Related Party Transactions	Related Party Transactions Horizon IP Agreement In January 2021, the Company entered into an intellectual property agreement (the “Horizon IP Agreement”) with Jiangsu Qingneng New Energy Technologies Co., Ltd. and Shanghai Qingneng Horizon New Energy Ltd. (together, “JS Horizon”) both of which are subsidiaries of the Company’s ultimate parent, Horizon. In September 2021, Jiangsu Horizon Powertrain Technologies Co. Ltd. (“JS Powertrain”) was an added party to the agreement. Pursuant to the agreement the parties convey to each other certain rights in intellectual property relating to Hyzon’s core fuel cell and mobility product technologies, under which Hyzon was to pay JS Horizon and JS Powertrain a total fixed payment of $10.0 million. The full $10.0 million has been paid, $6.9 million was paid in 2021 and the remaining $3.1 million was paid in February 2022. Related Party Payables and Receivables Horizon Fuel Cell Technologies and Related Subsidiaries Hyzon utilizes Horizon and its subsidiaries to supply certain fuel cell components. The Company made a deposit payment to Horizon in the amount of $5.0 million in March 2021, and additional deposit payments totaling $4.4 million in 2022 to secure fuel cell components, which are included within Prepaid expenses and other current assets in the unaudited interim Consolidated Balance Sheets. Certain employees of Horizon and its subsidiaries provide research and development, staff training, and administrative services to the Company. Based on an analysis of the compensation costs incurred by Horizon and an estimate of the proportion of effort spent by such employees on each entity, an allocation of approximately $0.2 million and $0.5 million was recorded in the Company’s unaudited interim Consolidated Statements of Operations and Comprehensive Income (Loss) related to such services for the three months ended June 30, 2022, a nd 2021, respectively.

Income (Loss) per share	Income (Loss) per share Basic net income (loss) per share is computed by dividing net income attributable to shareholders of Hyzon by the weighted-average number of common shares outstanding during the reporting period. Diluted net income per share is computed similarly to basic net income per share, except that it includes the potential dilution that could occur if dilutive securities were exercised. The following table presents the information used in the calculation of the Company’s basic and diluted net income (loss) per share attributable to Hyzon common stockholders (in thousands, except per share data): Three Months Ended Six Months Ended 2022 2021 2022 2021 Net income (loss) attributable to Hyzon $ 41,999 $ (9,421) $ 35,476 $ (17,568) Weighted average shares outstanding: Basic 248,056 166,249 247,999 166,225 Effect of dilutive securities 10,209 — 10,773 — Diluted 258,265 166,249 258,772 166,225 Net income (loss) per share attributable to Hyzon: Basic $ 0.17 $ (0.06) $ 0.14 $ (0.11) Diluted $ 0.16 $ (0.06) $ 0.14 $ (0.11) The weighted average number of shares outstanding prior to Business Combination were converted at the Exchange Ratio. Potentially dilutive shares are excluded from the computation of diluted net income (loss) per share when their effect was antidilutiv e.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Orten Business Combination Cancellation In June 2022, the Company entered into an agreement with the intention of acquiring 100% of outstanding ownership in Orten Betriebs GmbH and subsidiaries, and Orten Electric Trucks GmbH (collectively “Orten”). Subsequently, in September 2022, the Company terminated the agreement. As a result of the termination, the Company transferred consideration of €8.5 million (approximately $8.4 million in USD) to Orten consisting of €6.1 million (approximately $6.1 million in USD) in cash and €2.4 million (approximately $2.3 million in USD) in vehicle inventory. Raven SR S1 LLC In December 2022, the Company entered into an agreement with Chevron New Energies and Raven, to invest in Raven SR S1 LLC. Raven SR S1 LLC intends to develop, construct, operate and maintain a solid waste-to hydrogen generation production facility located in Richmond, California. The Company invested $8.5 million at closing, and the remaining $1.5 million will be paid in 2023 for an approximate 20% ownership in Raven SR S1 LLC. The Company accounted for the agreement as an equity method investment with a cost basis determined by the funding date capital contribution. The subsequent payment will add to the overall cost basis of the investment when paid. Divestiture of Hyzon Guangdong In December 2022, the Company sold all of its equity interest in Hyzon Motors Technology (Guangdong) Co., Ltd. (“Hyzon Guangdong”) to Hymas for approximately $3.1 million in cash, subject to certain adjustments. As a common control transaction, the difference of $0.5 million between the consideration received and the book value is expected to be recognized in the Company’s additional paid-in-capital during the three months ended December 31, 2022. Subsequent to the divestiture, Hyzon Guangdong changed its name to Guangdong Qingyun Technology Co. Ltd. (“Guangdong Qingyun”). Additionally, together with the execution of the Hyzon Guangdong divestiture, the Company entered into a share buyback agreement and repurchased approximately 3.8 million shares of common stock from Hymas in exchange for approximately $6.4 million in cash. In April 2023, Guangdong Qingyun paid $3.3 million to the Company to settle intercompany balances and Hymas paid the Company $3.1 million related to the Hyzon Guangdong divestiture. Nasdaq Deficiency Notice In February 2023, the Company received a Staff Determination from the Listing Qualifications Staff of Nasdaq notifying the Company that unless the Company requests an appeal, trading of the Company's Class A common stock and warrants will be suspended from The Nasdaq Capital Market at the opening of business on February 14, 2023, and a Form 25-NSE will be filed with the SEC. On February 10, 2023, the Hearings Panel granted the Company a 15 calendar day stay of delisting, and will notify the Company within this 15 calendar day period whether the Company’s request for a stay pending the hearing will be granted. The date for the delisting hearing was March 16, 2023. At the hearing, the Company presented its plan to regain compliance with Nasdaq Listing Rule 5250(c)(1) and requested the continued listing of its securities on The Nasdaq Capital Market pending such compliance. In March 2023, the Company received a letter from the Hearings Panel indicating that the Hearings Panel granted the Company’s request for continued listing until May 15, 2023, in order to allow the Company to regain compliance with the periodic filing rule. On April 6, 2023, the Company received an additional Staff Determination (the “Additional Staff Determination”) from the Staff notifying the Company that, because the Staff did not receive the Company’s Form 10-K for the year ended December 31, 2022, the Company does not comply with Nasdaq’s Listing Rules for continued listing, thus constituting an additional basis for delisting the Company’s securities from The Nasdaq Capital Market. The Additional Staff Determination further notified the Company that the Hearings Panel will consider this matter in their decision regarding the Company’s continued listing on The Nasdaq Capital Market, and that the Company should present its views with respect to this additional deficiency to the Hearings Panel in writing no later than April 13, 2023. On April 13, 2023, the Company filed its response to the Additional Staff Determination. Delaware Court of Chancery Section 205 On February 13, 2023, the Company filed a petition under the caption In re Hyzon Motors Inc., C.A. No. 2023-0177-LWW (Del. Ch) in the Delaware Court of Chancery pursuant to Section 205 of the Delaware General Corporation Law (“DGCL”), which permits the Court of Chancery, in its discretion, to validate potentially defective corporate acts due to developments regarding potential interpretations of the DGCL stemming from the Court’s recent decision in Garfield v. Boxed, Inc., 2022 WL 17959766 (Del. Ch. Dec. 27, 2022). On March 6, 2023, the Court of Chancery granted our petition, holding that any defects that may have existed with respect to the conduct of the Special Meeting of Shareholders held on July 15, 2021 to approve the increase in the Company’s authorized share capital were ratified as of the meeting. The Company continues to believe that, notwithstanding the relief the Delaware Court of Chancery granted to the Company under Section 205, at the time of DCRB Shareholder Meeting on July 16, 2021, the increase in the Company’s authorized share capital was validly approved by DCRB’s shareholders under Delaware law.
