- Ensure tax credits like the 45Z clean fuel production credit, 45Q carbon capture tax credit, and 40B sustainable aviation fuel tax credit are awarded using the U.S. Department of Energy’s Argonne Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation (GREET) model, so that American farmers and biorefiners can contribute to the creation of a vibrant market for SAF.
- Approve the Adopt GREET Act, which would require the U.S. Environmental Protection Agency (EPA) to update its lifecycle analysis model to account for all of the emissions reductions achieved by using bioethanol.
- Enact their own sustainable aviation fuel tax credits in order to incentivize production.
What Is Sustainable Aviation Fuel (SAF)?
SAF is broadly defined as any fuel used in planes that is derived (in whole or in part) from renewable resources. Under the Inflation Reduction Act (IRA), to qualify as SAF, the fuel must achieve at least a 50% GHG emission reduction compared to base jet fuel.
How Is Sustainable Aviation Fuel Made?
Farm-based feedstocks are the only sources of clean, renewable energy available in large enough volumes to deliver on our SAF decarbonization goals. In a novel process called ethanol-to-jet (ETJ), ethanol is dehydrated into ethylene and then fed through a series of other chemical processes that eventually yield sustainable jet fuel.
What Impact Would Growth Energy’s Policy Priorities Have on Consumers, the Economy, or the Environment?
Major airlines across the globe and here in the U.S. have made commitments to (and investments in) SAF. President Biden’s Sustainable Aviation Fuel Grand Challenge aims to produce enough low-carbon jet fuel to slash aviation emissions by half in 2050. The ethanol industry is best positioned to deliver SAF at commercial scale.
With current technologies, farm-based feedstocks – including ethanol and corn oil – are the primary source of clean, renewable energy that can be used to produce volumes large enough to meet the demand. As a result, harnessing the U.S. ethanol industry – which at 17.4 billion gallons per year accounts for over 80% of biofuel production in the U.S. – will be necessary to achieve U.S. goals for decarbonizing the aviation sector.
