At least 60 companies are now involved in the research and development of fixed-wing electric aircraft, according to BloombergNEF. The consultancy Roland Berger estimates there are 100 electric aviation programs in development around the world. Medium- and long-haul aviation (flights over two hours) accounts for roughly 73% of aviation emissions. With electric aviation companies trying to line up production, the bottlenecks could get worse, Islam says. As aviation companies look to decarbonize, sustainable aviation fuel (SAF) — an umbrella term for substitutes to fossil-based kerosene — has emerged as a greener alternative to conventional jet fuel.
