Octopus Hydrogen will supply renewable hydrogen to ZeroAvia's research and development center at Cotswold Airport, delivering some of the first clean hydrogen to the UK southwest.

A hydrogen fuel cell aviation demonstration project involving a 250–300 nautical mile test flight. The main test is planned for summer in Orkney, Scotland.

ZeroAvia's comprehensive initiative integrating renewable hydrogen production with zero-emission flight operations, including refueling infrastructure and aircraft testing.

An electric propulsion system incorporating high-efficiency proprietary inverter and motor technology, designed for hydrogen-electric aviation.

A scaled-up version of ZeroAvia's powertrain, planned to be 2 MW and utilize liquid hydrogen, targeting larger aircraft.

A zero-emission aircraft propulsion system powered by hydrogen fuel cells, designed to deliver equivalent performance to conventional aircraft engines at substantially lower operating costs. Planned for commercial supply to aircraft operators and manufacturers starting in 2022.
