CAeS is an agile and entrepreneurial company with whole aircraft concept design and UK CAA aircraft. We are a Design Organisation (DOA) and aircraft Production Organisation (POA) with capability/approvals. We are based on Cranfield (commercial & research) Airport with direct access to Cranfield University research capabilities & facilities.
Battery-only electric propulsion is zero-emission but very limited in range due to regulatory reserve requirement.
Battery-turbogenerator hybrid provides adequate range but emits CO2 for the majority of flight (after 10 minutes).
Hydrogen fuel cell propulsion allows adequate range (including regulatory reserve) with zero emissions.
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.
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:
Our H2 fuel cell system offers zero emissions for the entire duration of the flight and provides a much larger range compared to alternatives.
