Zero Avia recently conducted what is claimed to be the first ever electric-powered flight of a commercial-scale aircraft in the UK, piloting the new version of its hydrogen fuel cell powertrain from its base at Cranfield Airport. A hydrogen-electric powertrain offers the same zero-emission potential of a battery-electric option, but has a much more promising energy-to-weight ratio, making it viable for commercial operations at a much larger scale and in a shorter time frame, says ZeroAvia. Additionally, its hydrogen-electric powertrain is projected to have lower operating costs due to the high cost of battery cycling in typical high-utilisation regional aircraft.
