Advancing the production and use of alternative jet fuels in Washington.

SB 5601 creates a new office within Washington state to coordinate research, development, and deployment of alternative jet fuels and renewable hydrogen. It establishes a competitive grant program to fund infrastructure like blending facilities, rail spurs, and fuel handling equipment - excluding land acquisition or permitting costs - and requires annual reporting on funded projects. The bill mandates reports on feedstock availability (particularly biomethane) for fuel production by 2026 and directs collaboration with tribes, agencies, and industry groups. Directly affecting state agencies, project developers, and renewable fuel producers, it focuses on advancing clean aviation fuels through public-private partnerships and infrastructure investment.
