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.
