Derivative Instruments and Hedging Activities Disclosure [Abstract]
Brookfield SAFE	Brookfield SAFE On October 2, 2022, the Company entered into the Brookfield SAFE. Under the Brookfield SAFE, the Company agreed to issue to Brookfield the right to certain shares of its capital stock, in exchange for the payment of $50,000 (the “Initial Purchase Amount”). The Brookfield SAFE is legal form debt. As a result of the Business Combination, the Brookfield SAFE can be converted into a maximum number of shares of 5,000,000. Management has elected to apply the Fair Value Option ("FVO") under ASC 825, Financial Instruments. As the Brookfield SAFE is accounted for under the FVO, the Brookfield SAFE is classified as a mark-to-market liability. On the fifth anniversary of the Brookfield SAFE, LanzaTech is required to repay in cash the Initial Purchase Amount less any Non-Repayable Amount (the “Remaining Amount”), as well as interest on such Remaining Amount of 8.0 percent, compounded annually. For each $50,000 of aggregate equity funding required for qualifying projects presented to Brookfield in accordance with the Brookfield Framework Agreement (discussed below), the Remaining Amount will be reduced by $5,000 (such cumulative reductions the “Non-Repayable Amount”) and converted into LanzaTech Shares at $10.00 per share, which was the share price paid by the PIPE investors in the Business Combination. Interest on the corresponding amount will be forgiven. Each project presented must meet certain criteria in order to be considered a qualifying project. Additionally, Brookfield may, at any time at its option, convert all or a portion of the Initial Purchase Amount less any amount that has already been converted or repaid into shares of LanzaTech capital stock at the same $10.00 per share price. The Brookfield SAFE has not yet converted as a qualifying financing has not yet occurred and no qualified project investments have been presented to Brookfield as of December 31, 2024. As of December 31, 2024 and 2023, the fair value of the Brookfield SAFE was $13,223 and $25,150 respectively and was recorded within Brookfield SAFE liability on the consolidated balance sheets. On February 14, 2025, the Company and Brookfield terminated the Brookfield SAFE and all rights and obligations, and concurrently entered into a Loan Agreement as defined in Note 19 - Subsequent Events. The Framework Agreement, as described below remains in full effect. Brookfield Framework Agreement On October 2, 2022, LanzaTech entered into a framework agreement with Brookfield (the “Brookfield Framework Agreement”). Under such agreement, LanzaTech agreed to exclusively offer Brookfield the opportunity to acquire or invest in certain projects to construct commercial production facilities employing carbon capture and transformation technology in the U.S., the European Union, the United Kingdom, Canada or Mexico for which LanzaTech is solely or jointly responsible for obtaining or providing equity financing, subject to certain exceptions. LanzaTech agreed to present Brookfield with projects that over the term of the agreement require equity funding of at least $500,000 in the aggregate. With respect to projects acquired by Brookfield, LanzaTech is entitled to a percentage of free cash flow generated by such projects determined in accordance with a hurdle-based return waterfall. Brookfield has no obligation under the Brookfield Framework Agreement to invest in any of the projects. There had been no investments in projects as of December 31, 2024 or 2023.
