ZeroAvia, a company with operations in the US and UK, says retrofitted 19-seat aircraft, powered by hydrogen fuel cells, is the most cost-effective way for regional commercial operators to introduce zero emission flying in the next few years.
It says retrofitting larger aircraft like the 50-seat and 70-seat ATR is feasible but would require liquid hydrogen whereas 19-seat aircraft could be powered by compressed hydrogen, ZeroAvia’s business development and project manager, Julian Renz, tells Smart Aviation APAC.
Compressed hydrogen stores less energy, than liquid hydrogen, but still produces sufficient energy to power a 19-seat aircraft, says Renz.
He says hydrogen pressurized at 350-bar is the sweet spot in space usage and in the next few years can power aircraft up to and including 19-seaters at a cost competitive price as compared to jet fuel - Link
