1.9% of all greenhouse gas emissions
2.5% of CO2 emissions
3.5% of 'effective radiative forcing' - a better measure
If aviation does nothing, it is forecast that the industry will represent 24% of global carbon emissions by 2050.
Industry is now committing to decarbonisation.
Hydrogen has 3 x the energy density of conventional aviation fuel and produces zero CO2 emissions – the most credible solution for aviation.
Gaseous hydrogen offers lower range potential than liquid but is easier and cheaper to make available in numerous small airfields by 2026.
Batteries have 1/10th energy density of conventional aviation fuel.
Hybrid-Electric solutions can be beneficial in cars, but the added weight means their adoption in aircraft results in minimal CO2 benefit.
Hydrogen is the best long term solution to decarbonise aviation.
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.
Conversion of 9-seat Britten- Norman Islander to hydrogen fuel cell propulsion
£7.1m grant-funded by Aerospace Technology Institute (ATI) through to producing aircraft systems demonstrator in 2023.
We aim to deliver a commercial product by 2026.

It is imperative to decarbonise aviation cost-effectively. CAeS strongly believe that H2 fuel cell
systems offer key commercial benefits over the alternatives.
H2 fuel cell systems offer:
World’s first regulatory-certified, zero emissions commercial aircraft
2026 – 9 Passengers
Conversion of existing airframes to liquid H2 for extra performance
2028 – 10 to 19 Passengers
New aircraft design, optimised for zero emissions
2032 – 20 to 50 Passengers
New aircraft design, optimised for zero emissions
2035 + 50 to 100 Passengers
