Debt Disclosure [Abstract]

Debt

2021 Bond Issuance

On April 15, 2021, on behalf of Gevo NW Iowa RNG, LLC, the Iowa Finance Authority ("the "Authority") issued $68,155,000 of its non-recourse Solid Waste Facility Revenue Bonds (Gevo NW Iowa RNG, LLC Renewable Natural Gas Project), Series 2021 (Green Bonds) (the "2021 Bonds") for NW Iowa RNG. The bond proceeds are being used as a source of construction financing alongside equity from the Company. The bonds were issued under a Trust Indenture dated as of April 1, 2021 (the "Indenture") between the Authority and Citibank, N.A. as trustee (the "Trustee"). The 2021 Bonds mature April 1, 2042. They initially bear interest at 1.50% per annum during the Initial Term Rate Period, (as defined in the Indenture) payable semi-annually on January 1 and July 1 of each year. The bonds are supported by a $71.2 million irrevocable direct pay letter of credit (the "Letter of Credit"), which expires April 4, 2024 (unless terminated earlier), and was issued by Citibank, N.A. The Trustee will draw sufficient amounts on the Letter of Credit to pay the principal and interest until the first mandatory tender date of April 1, 2024. The bonds are callable and re-marketable on or after October 1, 2022. If the bonds have not been called and re-marketed by the first mandatory tender date the Trustee may draw on the Letter of Credit to repay the bonds in their entirety at the purchase price. Gevo deposited $71.2 million with Citibank, N.A. as restricted cash to secure any amounts drawn under the Letter of Credit. As of March 31, 2022, no amounts have been drawn under the Letter of Credit.

Gevo anticipates re-marketing the 2021 Bonds in the fall of 2022 under revised terms that will include a long-term maturity date and be non-recourse to Gevo. Upon a successful remarketing, Gevo anticipates that the Letter of Credit, the associated reimbursement agreement and the associated pledge of cash will be terminated, with a concurrent release of the restricted cash securing the Letter of Credit.

The 2021 Bonds were issued at a premium of $0.8 million, and debt issuance costs were $3.0 million. The bond debt is classified as long-term debt and is presented net of the premium and issuance costs, which are being amortized over the life of the bonds using the interest method. As of March 31, 2022, the premium balance, and debt issuance cost net of amortization were $0.6 million and $2.1 million, respectively.

Restricted cash and cash equivalents. The Company’s restricted cash and restricted cash equivalents consists of unused proceeds from the issuance of the 2021 Bonds, and are restricted for the purpose of constructing NW Iowa RNG projects as well as amounts pledged and assigned to Citibank, N.A. in its capacity as provider of the Letter of Credit as collateral for the reimbursement obligations of Gevo.

The proceeds from issuance of the 2021 Bonds are maintained by the Trustee under the Indenture and are released to the Company only to pay costs of the construction of NW Iowa RNG. The Company has used $53.0 million for the project. As of March 31, 2022, unused bond proceeds of $15.2 million are included in restricted cash classified as current since the proceeds will be distributed within 12 months. We expect all construction invoices will be received and paid, and the remaining unused bond proceeds will be released to reimburse Gevo by the end of the second quarter of 2022.

As of March 31, 2022, $71.2 million is held in restricted cash as collateral for the Letter of Credit. The Company is entitled to receive interest income on the restricted cash.

The restricted cash held by the Trustee is made up of the following (in thousands). Numbers are stated since inception and as of March 31, 2022:

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

Accounting standards define fair value, outline a framework for measuring fair value, and detail the required disclosures about fair value measurements. Under these standards, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in the principal or most advantageous market. Standards establish a hierarchy in determining the fair market value of an asset or liability. The fair value hierarchy has three levels of inputs, both observable and unobservable. Standards require the utilization of the highest possible level of input to determine fair value.

Level 1 – inputs include quoted market prices in an active market for identical assets or liabilities.

Level 2 – inputs are market data, other than Level 1, that are observable either directly or indirectly. Level 2 inputs include quoted market prices for similar assets or liabilities, quoted market prices in an inactive market, and other observable information that can be corroborated by market data.

Level 3 – inputs are unobservable and corroborated by little or no market data.

The carrying value and fair value, by fair value hierarchy, of the Company's financial instruments at March 31, 2022, and December 31, 2021, respectively, are as follows (in thousands):


			Fair Value Measurements at March 31, 2022

There were no transfers to or from Level 3 in the three months ended March 31, 2022.

For the 2021 Bonds, the fair values are estimated using the Black-Derman-Toy interest rate lattice framework. The effective maturity of the 2021 Bonds was assumed to be April 1, 2024 (three years from issuance) with repayment of 100% of principal on that date. The impact of the Company's optional redemption feature, effective October 1, 2022, is appropriately captured by the Black-Derman-Toy interest rate lattice. The carrying values and estimated fair values of the 2021 bonds as of March 31, 2022, are summarized as follows:


	March 31, 2022
	Carrying Value		Estimated Fair Value

2021 Bonds	$	68,155	$	66,657

The Company has not elected the fair value option for any of its instruments.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities.

Commitments and Contingencies	Mar. 31, 2022
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal matters. From time to time, the Company has been, and may again become, involved in legal proceedings arising in the ordinary course of its business. The Company is not presently a party to any litigation and is not aware of any pending or threatened litigation against the Company that it believes could have a material adverse effect on its business, operating results, financial condition or cash flows. Indemnifications. In the ordinary course of its business, the Company makes certain indemnities under which it may be required to make payments in relation to certain transactions. As of March 31, 2022, the Company did not have any liabilities associated with indemnities. In addition, the Company, as permitted under Delaware law and in accordance with its amended and restated certificate of incorporation and second amended and restated bylaws, in each case, as amended to date, indemnifies its officers and directors for certain events or occurrences, subject to certain limits, while the officer or director is or was serving at the Company’s request in such capacity. The duration of these indemnifications, commitments, and guarantees varies and, in certain cases, is indefinite. The maximum amount of potential future indemnification is unlimited; however, the Company has a director and officer insurance policy that may enable it to recover a portion of any future amounts paid. The Company accrues for losses for any known contingent liability, including those that may arise from indemnification provisions, when future payment is probable. No such losses have been recorded to date. Environmental liabilities. The Company’s operations are subject to environmental laws and regulations adopted by various governmental authorities in the jurisdictions in which it operates. These laws require the Company to investigate and remediate the effects of the release or disposal of materials at its locations. Accordingly, the Company has adopted policies, practices and procedures in the areas of pollution control, occupational health and the production, handling, storage and use of hazardous materials to prevent material environmental or other damage, and to limit the financial liability which could result from such events. Environmental liabilities are recorded when the Company’s liability is probable, and the costs can be reasonably estimated. No environmental liabilities have been recorded as of March 31, 2022. In February 2022, an incident occurred at one of the anaerobic digesters that is part of NW Iowa RNG that resulted in the accidental discharge of a mixture of water and manure into the environment. We promptly notified the Iowa Department of Natural Resources (the "DNR") and began mitigation work to minimize the impact of the discharge. The DNR has issued a notice of violation in connection with the discharge. In April 2022, two separate incidents occurred at two of the anaerobic digesters that are part of NW Iowa RNG that resulted in the accidental discharge of very small amounts of water and manure into the environment. The DNR has issued notices of violation in connection with the two discharges. There is a possibility that the DNR will initiate an enforcement action with respect to the discharges described above that could result in a monetary sanction being levied against Gevo for the accidental discharges. We do not believe that any such monetary sanctions would be material to the Company.

Segment Reporting [Abstract]

Segments

The Company's chief operating decision maker is provided with and reviews a monthly executive package which separately identifies its business segments based on the nature of the products and services offered through each of its consolidated legal entities. In January 2021, the Company began to separately identify the Renewable Natural Gas Segment in the monthly executive package. As such, the Company has determined that it has three operating segments: (i) Gevo segment; (ii) Agri-Energy segment; (iii) Renewable Natural Gas segment. Transactions between segments are eliminated in consolidation.

Gevo segment. The Gevo segment is responsible for all research and development activities related to the future production of SAF, commercial opportunities for other renewable hydrocarbon products, such as hydrocarbons for gasoline blendstocks and diesel fuel; ingredients for the chemical industry, such as ethylene and butenes; plastics and materials; and other chemicals. The Gevo segment also develops, maintains and protects its intellectual property portfolio, provides corporate oversight services, and responsible for development and construction of our Net-Zero projects.

Agri-Energy segment. The Agri-Energy segment is currently responsible for the operation of the Company’s Luverne Facility, development and optimization of the production of isobutanol, ethanol and related products.

Net loss Per Share

3 Months Ended

Mar. 31, 2022

Earnings Per Share [Abstract]

Net loss Per Share

Basic net loss per share is calculated based on the weighted average number of common shares outstanding for the period. Diluted net loss per share is calculated based on the assumption that stock options and other dilutive securities outstanding, which have an exercise price less than the average market price of the Company's common shares during the period, would have been exercised on the later of the beginning of the period or the date granted and that the funds obtained from the exercise were used to purchase common shares at the average market price during the period. None of the Company's stock options or other dilutive securities are considered to be dilutive in periods with net losses.

The effect of the Company’s dilutive securities is calculated using the treasury stock method and only those instruments that result in a reduction in net income per common share are included in the calculation. Diluted net loss per share for the three months ended March 31, 2022 and 2021 excluded 1,751,170 and 220,099, respectively, of common stock equivalents because the effect of their inclusion would be anti-dilutive or would decrease the reported net loss per share.

Basic and diluted net loss per share is calculated as follows (net loss in thousands):

Revenues from Contracts with Customers and Other Revenues	3 Months Ended

Revenue from Contract with Customer [Abstract]
Revenues from Contracts with Customers and Other Revenues	Revenues from Contracts with Customers and Other RevenuesThe Company's limited revenues are derived from two development-scale plants: (i) the South Hampton Facility and (ii) the Luverne Facility. These revenues are from customer contracts for ethanol sales and related products and hydrocarbon revenues, which include SAF, isooctene, and isooctane. These are sold mostly on a free-on-board, shipping point basis (recognized at a point in time), are independent transactions, do not provide post-sale support or promises to deliver future goods, and are single performance obligations. Historically, grant revenues consisted of governmental and cooperative research grants, while other revenue includes consulting services and short-term leases for certain storage facilities at the Luverne Facility. For the quarters ended March 31, 2022 and 2021, there were no variable revenues and as of March 31, 2022 and December 31, 2021, there were no remaining unfulfilled or partially fulfilled performance obligations. The Company does not offer explicit or implicit price concessions, so it records the revenue and trade receivables at 100% of the transaction price. Since all amounts are provided and due in less than one year, the Company elects to not record a financing component.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Stock-Based Compensation

3 Months Ended

Mar. 31, 2022

Equity [Abstract]

Stock-Based Compensation

Equity incentive plans. In February 2011, the Company’s stockholders approved the Gevo, Inc. 2010 Stock Incentive Plan (as amended and restated to date, the "2010 Plan"), and the Employee Stock Purchase Plan (the "ESPP").

The 2010 Plan provided for the grant of non-qualified stock options, incentive stock options, stock appreciation rights, restricted stock awards, restricted stock units and other equity awards to employees and directors of the Company. On June 9, 2021, with approval of stockholders at the 2021 Annual Meeting of Stockholders, the 2010 Plan was amended and restated, which increased the number of shares of common stock reserved for issuance under the 2010 Plan to a total of 22,980,074. At March 31, 2022, 7,717,026 shares remained available for awards under the 2010 Plan.

Restricted common stock and non-qualified stock option activity during the three months ended March 31, 2022, consisted of the following:


Period	Total Number of Restricted Shares Issued		Total Number of Non-qualified Stock Options Granted	Vesting Periods Years

January 1, 2022 to March 31, 2022	(340,502)	(1)	—	N/A



Total	(340,502)		—

(1)Includes shares of common stock cancelled related to the unvested restricted stock awards.

ESPP. The offering periods for the ESPP are from January 1 to June 30 and from July 1 to December 31 of each calendar year. The Company has reserved 190 shares of common stock for issuance under the ESPP, of which 190 shares as of March 31, 2022, are available for future issuance. The purchase price of the common stock under the ESPP is 85% of

the lower of the fair market value of a share of common stock on the first or last day of the purchase period. There were no purchases of common stock under the ESPP during the three months ended March 31, 2022 or 2021.

Stock-based compensation expense. The Company records stock-based compensation expense during the requisite service period for share-based payment awards granted to employees and non-employees.

Our stock-based compensation is classified as either an equity award or a liability award in accordance with generally accepted accounting principles. The fair value of an equity-classified award is determined at the grant date and is amortized on a straight-line basis over the vesting life of the award. The fair-value of a liability-classified award is determined on a quarterly basis through the final vesting date and is amortized based on the current fair value of the award and the percentage of vesting period incurred to date.

The following table sets forth the Company’s stock-based compensation expense for the periods indicated (in thousands):

Stock option award activity. Stock option activity under the Company’s stock incentive plans and changes during the three months ended March 31, 2022, were as follows:


	Number of Options	Weighted-Average Exercise Price (1)		Weighted-Average Remaining Contractual Term (years)	Aggregate Intrinsic Value

Options outstanding at December 31, 2021	4,739,940	$	5.14	9.6	$	—

(1) Exercise price of options outstanding range from $4 to $99,300 as of March 31, 2022. The higher range is related to historical stock reverse splits.

No stock options vested during the three months ended March 31, 2022. As of March 31, 2022, the total unrecognized compensation expense, net of estimated forfeitures, relating to stock options was $16.6 million, which is expected to be recognized over the remaining weighted-average period of approximately 3.6 years.

Restricted stock. Non-vested restricted stock awards and the changes during the three months ended March 31, 2022, were as follows:


	Number of Shares	Weighted-Average Grant-Date Fair Value

Outstanding at December 31, 2021	7,094,785	$	3.93

Non-vested at March 31, 2022	6,754,283	$	4.01

The total fair value of restricted stock that vested during the three months ended March 31, 2022, was nil. As of March 31, 2022, the total unrecognized compensation expense, net of estimated forfeitures, relating to restricted stock awards was $19.4 million, which is expected to be recognized over the remaining weighted-average period of approximately 2.9 years. As of March 31, 2022, we had recorded a liability of $1.0 million for earned and unvested liability-classified restricted stock awards based on the fair value of our common stock as of March 31, 2022.

Leases, Right-of-Use Assets and Related Liabilities

Leases [Abstract]

Leases, Right-of-Use Assets and Related Liabilities

The Company is party to an operating lease contract for the Company’s office and research facility in Englewood, Colorado, that expires in January 2029. The lease contains an option to extend the lease which management does not reasonably expect to exercise, so it is not included in the length of the term. The Company also has one production line piece of equipment with an operating lease that expires in 2024. As of March 31, 2022, right-of-use assets under operating leases totaling $2.2 million are included in "Operating right-of use assets," and related lease liabilities totaling $2.3 million ($0.4 million in current and $1.8 million in long-term) are included in the Consolidated Balance Sheets.

The Company also has four finance leases for land under arrangements related to NW Iowa RNG. Under these contracts, the Company leases land from dairy farmers on which it has built three anaerobic digesters, related equipment and pipelines to condition raw biogas from cow manure provided by the farmers. The partially conditioned biogas will be transported from the three digester sites to a central gas upgrade system located at the fourth site that will upgrade the biogas to pipeline quality RNG for sale. These leases expire at various dates between 2031 and 2050. Since the Company adopted the practical expedient, all amounts paid to the lessor under these arrangements for cow manure and non-lease services are classified as lease payments and are included in the calculation of the right-of-use assets and lease liabilities. This results in significantly higher right-of-use assets and lease liabilities than if the Company did not elect this practical expedient. The Company also has one office equipment finance lease, which expires in 2025. As of March 31, 2022, right-of-use assets under finance leases totaling $26.9 million are included in "Finance right-of-use assets," and related lease liabilities totaling $21.4 million ($4.0 million in current and $17.4 million in long-term) are included in the Consolidated Balance Sheets.

The following table presents the (a) costs by lease category and (b) other quantitative information relating to the Company’s leases (in thousands):

Variable lease cost (2)	115		39

Total lease cost	$	1,359	$	243

(1)$0.6 million and $0.4 million of amortization and interest expense for the three months ended March 31, 2022 and 2021, respectively, were capitalized as part of construction in progress, for related finance lease liabilities of $23.0 million and $0.6 million, respectively. The accumulated capitalized amounts of $3.0 million are included in "Property, plant and equipment, net" in the Consolidated Balance Sheets as the related NW Iowa RNG facilities were still under construction on March 31, 2022. Since these leases include approximately 75% fuel supplies, when the RNG facilities reach 60% production (expected in the second or third quarter of 2022), these capitalized amounts will be moved to inventory, and as units are sold they will be expensed through cost of goods sold.

(2)Represents amounts incurred in excess of minimum payments, including payments for common area expenses under our office and research facility lease, and additional amounts due under our NW Iowa RNG leases based on the number of cows maintained by the owners above the minimum required by the contracts of the respective facilities.

Nature of Business, Financial Condition and Basis of Presentation	3 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business, Financial Condition and Basis of Presentation	Nature of Business, Financial Condition and Basis of Presentation Nature of business. Gevo, Inc. (Nasdaq: GEVO) ("Gevo" or the "Company," which, unless otherwise indicated, refers to Gevo, Inc. and its subsidiaries), a Delaware corporation founded in 2005, is a growth-oriented company with the mission of solving greenhouse gas emissions for those sectors of the transportation industry that are not amenable to electrification or hydrogen. The Company is focused on transforming renewable energy into energy-dense liquid hydrocarbons that can be used as renewable fuels, such as sustainable aviation fuel ("SAF"), with the potential to achieve a “net-zero” greenhouse gas ("GHG") footprint. The Company uses the Argonne National Laboratory’s GREET (Greenhouse gases, Regulated Emissions, and Energy use in Transportation) model (the "GREET Model") to measure, predict and verify GHG emissions across the life-cycle of its products. The “net-zero” concept means Gevo expects that by using renewable and substantially decarbonized energy sources, drop-in hydrocarbon fuels can be produced that have a net-zero, full life cycle footprint measured from the capture of renewable carbon through the burning of the fuel. Gevo's primary market focus, given current demand and growing customer interest, is SAF. The Company believes it also has commercial opportunities for other renewable hydrocarbon products, such as (i) hydrocarbons for gasoline blendstocks and diesel fuel, (ii) ingredients for the chemical industry, such as ethylene and butenes, and (iii) plastics, materials and other chemicals. The Company believes it has the technology and know-how to convert various carbohydrate feeds through a fermentation process into alcohols and then transform the alcohols into renewable fuels and materials. While the Company expects its first major capital deployments to focus on the production of SAF, Gevo recognizes that there are opportunities to operate in several different markets, and it will pursue those opportunities when appropriate based on customer interest, access to capital and expected investment returns. Gevo currently operates a wholly-owned development plant in Luverne, Minnesota (the "Luverne Facility"). The Luverne Facility was originally constructed in 1998 and is located on approximately 55 acres of land, which contains approximately 50,000 square feet of building space. Our Luverne Facility is a scale up and development site. Gevo intends to use the Luverne Facility to prove our processes, process concepts, unit operations and for other purposes in order to optimize feedstocks and the processes used for producing hydrocarbons from alcohols. Gevo's renewable natural gas ("RNG") project ("NW Iowa RNG") owned by Gevo NW Iowa RNG, LLC, will generate RNG captured from dairy cow manure supplied by three dairies located in Northwest Iowa totaling over 20,000 milking cows. Animal manure can be digested anaerobically to produce biogas, which is then upgraded to pipeline quality gas referred to as RNG. Gevo NW Iowa RNG, LLC intends to sell RNG to the California market through an agreement with BP Canada Energy Marketing Corp. and BP Products North America Inc. (collectively, "BP"). Our dairy farm partners realize a variety of benefits including improved operational and environmental compliance options. These services facilitate long-term relationships with project hosts that may serve as a source for future projects and relationships. Gevo believes that RNG has potential to displace fossil-based natural gas used in the future production of net-zero hydrocarbon manufacturing facilities, providing the benefit of lowering the carbon intensity of hydrocarbon fuels. In 2021, we began construction on NW Iowa RNG under a self-perform project delivery format. We completed most of the construction efforts at the end of 2021, and in January 2022, we began the process of commissioning the project. NW Iowa RNG is expected to be completed within budget. All digesters are currently in the start-up phase and are expected to reach steady production levels in the second quarter of 2022. When fully operational, NW Iowa RNG is expected to generate approximately 355,000 MMBtu of RNG per year. We also operate a demonstration facility in Silsbee, Texas in partnership with South Hampton Resources, Inc. (the "South Hampton Facility"), from which the Company produces limited volumes of SAF and liquid hydrocarbon fuel. Ultimately, the Company believes that the attainment of profitable operations is dependent upon future events, including, but not limited to (i) the successful development of the Company's initial Net-Zero Project (the "Net-Zero 1 Project") and future projects for the production of energy dense liquid hydrocarbons using renewable energy and our proprietary technology; and (ii) the achievement of a level of revenues adequate to support its cost structure. Basis of presentation. The unaudited consolidated financial statements of the Company (which include the accounts of its wholly-owned subsidiaries Gevo Asset, LLC, Gevo RNG HoldCo, LLC, Gevo NW Iowa RNG, LLC, Gevo Net-Zero HoldCo, LLC, Gevo Net-Zero 1, LLC, and Agri-Energy, LLC (“Agri-Energy”)) have been prepared, without audit, pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all information and footnotes required by accounting principles generally accepted in the United States (“GAAP”) for complete financial statements. These statements reflect all normal and recurring adjustments which, in the opinion of management, are necessary to present fairly the financial position, results of operations and cash flows of the Company as of, and for the three months ended, March 31, 2022, and are not necessarily indicative of the results to be expected for the full year. These statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included under the heading “Financial Statements and Supplementary Data” in Part II, Item 8 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. The financial statements at December 31, 2021, have been derived from the audited financial statements as of that date. For further information, refer to our audited financial statements and notes thereto included for the year ended December 31, 2021 (the "2021 Annual Report"). Reclassifications. The Company reclassified certain prior period amounts to conform to the current period presentation, including the categorization of depreciation and amortization on the Consolidated Statements of Operations. These reclassifications had no impact on total revenues, total cost of goods sold, total operating expenses, net loss or stockholders' equity for any period.

Basis of presentation	Basis of presentation. The unaudited consolidated financial statements of the Company (which include the accounts of its wholly-owned subsidiaries Gevo Asset, LLC, Gevo RNG HoldCo, LLC, Gevo NW Iowa RNG, LLC, Gevo Net-Zero HoldCo, LLC, Gevo Net-Zero 1, LLC, and Agri-Energy, LLC (“Agri-Energy”)) have been prepared, without audit, pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all information and footnotes required by accounting principles generally accepted in the United States (“GAAP”) for complete financial statements. These statements reflect all normal and recurring adjustments which, in the opinion of management, are necessary to present fairly the financial position, results of operations and cash flows of the Company as of, and for the three months ended, March 31, 2022, and are not necessarily indicative of the results to be expected for the full year. These statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included under the heading “Financial Statements and Supplementary Data” in Part II, Item 8 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. The financial statements at December 31, 2021, have been derived from the audited financial statements as of that date. For further information, refer to our audited financial statements and notes thereto included for the year ended December 31, 2021 (the "2021 Annual Report").

The Company reclassified certain prior period amounts to conform to the current period presentation, including the categorization of depreciation and amortization on the Consolidated Statements of Operations.

Subsequent Events [Abstract]
Subsequent Events	Subsequent EventsIn April 2022, Gevo signed an amendment to its Fuel Supply Agreement with Rock River Jerseys, LLC ("RRJ") to reimburse RRJ for part of the cost to install and operate covers for the lagoons at the RRJ dairy. This will allow Gevo to optimize efficiencies and could significantly improve the carbon intensity score at NW Iowa RNG. The Company's estimated share of the total capital cost for the improvements is approximately $1.9 million. The installation is expected to be completed early in the third quarter of 2022.
