French electric aircraft manufacturer, Beyond Aero, has taken a significant step towards commercializing the BYA-1, the first certified hydrogen-electric light jet designed for zero-emissions aviation with affordable maintenance costs. The company aims to deliver the BYA-1 by 2030, featuring a battery-free hydrogen fuel cell system and two electric engines for redundancy. With a 2.4MW fuel cell stack capacity and a range of 800 nautical miles, the aircraft prioritizes safety with strategically placed hydrogen tanks and electric ducted fans for improved efficiency. Beyond Aero's powertrain for the BYA-1 boasts 90% fewer moving parts, streamlining maintenance and operation and reducing costs by up to 55%. The company projects hydrogen fuel to be a cost-efficient option compared to sustainable aviation fuels, making it attractive for the aviation industry's energy transition. While hydrogen propulsion technology faces challenges, companies like Beyond Aero, Universal Hydrogen, and Airbus are investing in its potential for the future of green aviation.
