Liquid Hydrogen for Flight: The Dawn of Zero-Emission Aviation
The aviation industry stands at the cusp of a transformative shift as liquid hydrogen emerges as a leading contender in the race toward decarbonized flight. Once the realm of concept studies and laboratory experiments, liquid hydrogen-powered aviation is now advancing rapidly, driven by a convergence of technological breakthroughs, strategic partnerships, and growing regulatory and societal pressure to achieve net-zero emissions by 2050.
Understanding Elastomer Compatibility with Sustainable Aviation Fuels
As the aviation industry intensifies its push toward decarbonization, sustainable aviation fuels (SAFs) have emerged as a vital pathway. These fuels promise up to 80% lifecycle CO2 emissions reductions over conventional Jet A fuel. However, SAFs differ significantly in chemical composition, particularly in their lack of aromatic compounds—an absence that raises critical compatibility questions for existing aircraft fuel systems, specifically for elastomeric seals such as O-rings.
Net Zero Aviation: SAF and Hydrogen Innovations Ahead
Fully formulated SAF, in contrast, mimics conventional aviation fuel in both composition and performance. It includes aromatics and all necessary hydrocarbons, making it a true drop-in fuel without requiring any modifications to aircraft. ASTM is currently developing standards to allow aircraft to operate on 100% fully formulated SAF, with completion expected by 2030.
Blazing a Sustainable Trail in Aviation: Introducing SAF
The aviation industry stands at the forefront of addressing climate change, striving to meet ambitious carbon neutrality goals by 2050. A critical element in this transformation is the adoption of Sustainable Aviation Fuel (SAF), a cleaner alternative to conventional jet fuel. Over the years, flight and ground tests using both blended and unblended SAF have demonstrated its potential to reshape aviation’s environmental footprint.
Two Emerging Exciting Green Projects in North Dakota and Minnesota
Sustainable Aviation Fuel is essential to the future of the aerospace industry, as it offers the opportunity to continue to build that industry with relatively few changes required in their entire regime – which one would have to agree is indeed very complex. The key difference here is that SAF fuel generally no longer comes from the petroleum industry but rather from the biomass industry.
SAF and Hydrogen Fuel Applications in Aerospace – Part 2
Airbus aims to bring to market the world’s first hydrogen-powered commercial aircraft by 2035. To achieve this, they have proposed the ZEROe project, which will explore a variety of configurations and technologies and prepare the ecosystem that will produce and supply the needed hydrogen. Airbus’ ZEROe program will use four original concepts.
