DOE, DOT, USDA, and EPA released an updated implementation
framework for the outgoing Administration's Sustainable
Aviation Fuel (SAF) Grand Challenge. The Grand Challenge called for
3 billion gallons of domestic SAF production by 2030, and 35
billion gallons by 2050.
The roadmap identifies a number of "gaps" that need to
be bridged in order for the goals to be achieved. These include
building more certainty in SAF supply chains, and expanding the
availability of purpose-grown feedstocks.
The report also calls for using existing ethanol and petroleum
industry infrastructure to quickly scale up SAF. Thus, the report
wisely calls for both new resources and the optimization of
existing resources to decarbonize the SAF supply chain.
