2023-05-02Unleaded aviation gasoline
Swift Fuels, a West Lafayette, Indiana-based company, presented on unleaded aviation gasoline at the Aviation Noise & Emissions Symposium 2023 at UC Davis. The company markets two premium unleaded avgas products: UL94, sold since 2015 with FAA STC approval and ASTM D7547 certification, and a forthcoming high-octane 100R formula. These fuels are designed as lead-free alternatives to conventional aviation gasoline, with approvals from both engine and airframe original equipment manufacturers. -
2023-03-05Aircraft Size Comparison – A320, A321, and Transcontinental/Transatlantic H2 Aircraft
The image compares four narrow-body aircraft configurations: the conventional Airbus A320 and A321, alongside two hydrogen-powered concept variants labeled 'Transcontinental H2' and 'Transatlantic H2.' The H2 variants show large cylindrical hydrogen fuel tanks visible in the aft fuselage section, illustrating how liquid hydrogen storage would be integrated into the A320/A321 airframe for medium- and long-range zero-emission flight. -
2023-01-23House Bill 1505 – Alternative Jet Fuel Industry in Washington
Washington House Bill 1505 (2023) aims to promote the production and use of sustainable aviation fuels (SAF) by establishing tax incentives, clean fuel credits, and research initiatives to grow the alternative jet fuel industry in the state. The bill defines 'alternative jet fuel' as lower-carbon fuels that can be blended with conventional jet fuel without modifying aircraft engines or existing infrastructure. Beyond reducing greenhouse gas emissions, the legislation highlights improved air quality benefits for airport workers and communities surrounding airports like Sea-Tac. -
2022-11-29Power of hydrogen – aircraft maintenance demonstration
Rolls-Royce technicians in high-visibility safety gear work on a jet engine mounted on a test stand bearing the Rolls-Royce logo and text referencing 'power of hydrogen' and 'decarbonise aviation.' This appears to be related to Rolls-Royce's hydrogen combustion engine testing program. -
Rolls-Royce tests a jet engine running on hydrogen
By Theo Leggett Business correspondent, BBC News In a windswept corner of a military site on Salisbury Plain a small aircraft jet engine is undergoing tests that could one day lead to huge changes within the aviation industry. The engine itself is almost completely conventional. It is a Rolls-Royce AE-2100A gas turbine, a design used -
2021-08-17Burien Airport Committee agenda and draft minutes, August 17, 2021
The Burien Airport Committee held virtual meetings in July and August 2021 to discuss issues related to Seattle-Tacoma International Airport and its surrounding community. Key topics included a presentation on the Sustainable Airport Master Plan (SAMP) covering 20 years of airport facility development, a briefing on Burien's Climate Action Plan, and an upcoming presentation on alternative jet fuels from Washington State University's ASCENT program. The committee also discussed zoning and land use near the airport and provided updates on the SEA Stakeholder Advisory Round Table (StART). -
2021-02-17Reducing emissions, contrails and climate impact from aviation – Highlights from recent aircraft campaigns
A 2021 seminar by DLR researcher Christiane Voigt examines how aviation contributes to climate change through CO2 emissions, contrail cirrus clouds, and NOx gases, with contrail cirrus identified as the largest single warming factor at 57.4 mW m⁻². The presentation outlines strategies to reduce aviation's climate footprint, including the use of alternative fuels, lean combustion technology, and contrail avoidance routing. Findings draw on data from recent aircraft measurement campaigns and observed emission reductions during the 2020 COVID-19 lockdown. -
2017-06-01Environment and sustainability programs
Seattle-Tacoma International Airport's Environment and Sustainability Programs outline the airport's efforts to become the greenest, most energy-efficient airport in North America across four key areas: air quality and emissions reduction, green transportation, waste reduction and recycling, and water and wildlife management. Initiatives include providing pre-conditioned air and electricity at gates to cut aircraft engine greenhouse gas emissions by over 40,000 metric tons, transitioning vehicles to cleaner energy sources, and working toward recycling 60 percent of solid waste by 2020. The airport also actively manages 160 acres of wetland habitat, uses avian radar to protect wildlife, and has relocated more than 800 birds to reduce hazards to aircraft.
