The Washington State Department of Transportation (WSDOT) Aviation Division has launched the Sustainable Aviation Grant program, aiming to support sustainable aviation initiatives. The program focuses on funding projects related to electric ground equipment, hydrogen electrolyzers, storage solutions, hangar charging technology, and mobile battery charging technology. Eligible applicants for this grant program include airport authorities, cities, counties, federally recognized Indian tribes, individuals, political subdivisions, or public corporations that own and operate public-use airports in the Washington Aviation System Plan. The application deadline for the program is August 16, and applicants must provide necessary supporting documentation along with airport aid grant assurances. WSDOT will assess project proposals based on diverse criteria, emphasizing environmental benefits for overburdened communities and vulnerable populations, reducing reliance on fossil fuels, mitigating the adverse impacts of aviation-related emissions, and fostering innovation in sustainable aviation technology. Following the evaluation process, WSDOT will compile a prioritized list of projects recommended for funding, which will be presented to the state legislature. Grant awards are slated to be distributed post-July 1, 2025, reflecting a positive step towards fostering sustainable aviation practices in Washington State.
