Hydrogen Technology

Hydrogen-electric powertrains: adaptable to suit multiple aircraft platforms.

Environmental impact of aviation

Aviation Emissions

1.9% of all greenhouse gas emissions

CO2 Emissions

2.5% of CO2 emissions

Radiative Forcing

3.5% of the net global warming effect

If aviation does nothing, it is forecast that the industry will represent 24% of global carbon emissions by 2050.

We won’t let that happen.

Why choose hydrogen aircraft for zero-emissions aviation

Zero CO2 Emissions

Hydrogen has 3 x the energy density of conventional aviation fuel and produces zero CO2 emissions – the most credible solution for aviation.

Easier & Cheaper

Gaseous hydrogen offers lower range potential than liquid but is easier and cheaper to make available in numerous small airfields by 2026.

1/10th Energy Density

Batteries have 1/10th energy density of conventional aviation fuel​.

More Beneficial Than Hybrid

Hybrid-Electric solutions can be beneficial in cars, but the added weight means their adoption in aircraft results in minimal CO2 benefit​.

Comparison of Sustainable Technology Solutions

Hydrogen is the best long term solution to decarbonise aviation.

Our Solution - Hydrogen Technology

Phase 1 - Prove

Phase 1 of our roadmap is “Project Fresson” – the conversion of a Britten-Norman Islander 9-seat aircraft from conventional fossil fuel to that of gaseous hydrogen propulsion.

This development is set to deliver the world’s first fully certified, truly green, passenger-carrying aircraft using hydrogen fuel cell technology.
