The Engineer Q&A: Green skies ahead

In-Depth

Leading voices from across aviation share their thoughts on how the sector can decarbonise and what the future of air travel will look like.

Mike Durham, Chief Technical Officer at Hybrid Air Vehicles

Riona Armesmith, Chief Technical Officer, Magnix

Dr Mark Bentall, Head of Technology Operations, Airbus

Sergey Kiselev, VP Europe, ZeroAvia

RA: At Magnix, we are developing world leading electric propulsion systems for the commercial aviation market. We are agnostic of the power source or aircraft platform and our products are well suited to both retrofit of existing aircraft and to clean sheet aircraft designs.

SK: ZeroAvia is the leading innovator in zero emission propulsion for aviation, based at a growing facility at Cotswold Airport in Kemble and in Hollister, California. We are doing this by developing hydrogen-electric powertrains, which use low carbon hydrogen in a fuel cell system to generate electricity, which in turn is used to power aircraft without any emissions besides water vapour. While Sustainable Aviation Fuels (SAFs) are limited in availability and still generate harmful climate emissions, and current and expected battery technologies do not meet the weight-sensitive performance needs of aerospace, hydrogen-electric solutions are able to provide the energy density required to accelerate truly zero emission flight.
