An aircraft propulsion system powered entirely by fuel cells rather than conventional combustion engines or hybrid battery-electric systems.

A hydrogen fuel cell powertrain uses a fuel cell stack to convert hydrogen and oxygen into electricity through an electrochemical reaction, which then powers electric motors to drive the vehicle, emitting only water vapor and heat at the point of use. Within the Cummins–Tata Motors collaboration, hydrogen fuel cells are part of the low- and zero-emission technology portfolio, and Tata has already demonstrated hydrogen fuel cell buses as part of its zero-emission public transport initiatives.[2]

Aircraft propelled by hydrogen fuel, examined in three design configurations: turbofan, turboprop, and blended wing. These represent zero-emission alternatives to conventional jet fuel-powered aircraft.

A joint research initiative between Air New Zealand and Airbus to explore the integration of hydrogen-powered aircraft into commercial aviation operations in New Zealand. The project involves analyzing operational impacts and developing a decarbonization roadmap.

Development of a hydrogen fuel cell-powered regional aircraft based on a Dash 8-300 testbed, equipped with a megawatt-class H2 fuel cell powertrain. The aircraft uses fuel cells without hybrid battery architecture.

Universal Hydrogen's first commercial product configuration, a conversion kit for ATR 72-600 regional airliners to enable hydrogen fuel cell propulsion.

A next-generation aircraft design featuring four 2-megawatt electric propulsion engines powered by hydrogen fuel cells and two liquid hydrogen tanks, designed as a stepping stone to unlock key technologies rather than a final commercial product.

A conversion kit for ATR 72-600 regional airliners to enable hydrogen fuel cell propulsion, representing Universal Hydrogen's first commercial product configuration.

A hydrogen fuel cell-powered regional aircraft based on a Dash 8-300 airframe, equipped with a megawatt-class H2 fuel cell powertrain. The aircraft eliminates hybrid battery architecture to reduce weight and lifecycle costs.
