An aviation startup has developed an aircraft powertrain that uses hydrogen for fuel, eliminating harmful emissions
Spotted: Aviation accounts for 12 per cent of global transportation carbon emissions, but it is also one of the fastest-growing sectors in transportation. Aeroplane emissions are released at high altitudes and have up to four times the impact of ground-based emissions. Yet the elimination of flying, which would bring an end to industries such as tourism which employ hundreds of millions of people, is out of the question at this time.
California-based company, ZeroAvia, is working on a solution. They have developed what they claim is the world’s first practical, emission-free, hydrogen-fueled aviation powertrain. The company was founded by cleantech entrepreneur, Val Miftakhov, and received £5.3 million in UK government funding to develop the technology through the test flight stage.
Initially, ZeroAvia plans to replace the piston engines in propeller aircraft with its new hydrogen powertrain, which includes hydrogen fuel cells, electric motors and gas storage. The goal is to enable smaller aircraft to fly for between 300 and 500 miles on hydrogen alone. This would also allow the economical use of smaller local airports for regional travel.
According to Miftakhov, hydrogen-based aircraft is also more economical than turbine engines, with greater efficacy, lower maintenance and cheaper engines to operate.
