On February 16, 2023, Representative Randy Feenstra (R-IA) introduced a legislative package that includes bills regarding researching the potential of biofuels to power jet engines and developing a commercially viable fuel cell system for cars and trucks powered exclusively by biofuels. The package includes:

• The Comparison of Sustainable Transportation (COST) Act would direct the Comptroller General of the U.S. Government Accountability Office (GAO) and the U.S. Secretary of Energy to compare the financial and environmental costs between replacing the entire federal gasoline-powered fleet with either electric vehicles or E-85 capable flex-fuel cars and trucks;
• The Biojet Fuel Research Act would direct the Federal Aviation Administration (FAA) to establish a working group focused on identifying research and development needs to produce biojet fuel. The working group would consist of the Bioenergy Technologies Office of the U.S. Department of Energy (DOE), the U.S. Department of Agriculture (USDA), biorefinery stakeholders, agriculture research universities, and others; and
• The Biofuel Cell Research Act would direct the DOE Secretary to establish a research, development, and demonstration program for a commercially viable fuel cell system that uses biofuels as the main fuel source.

Feenstra introduced similar legislation in the 117th Congress.
