GKN Leads UK Group Developing Hydrogen Propulsion For Sub-Regional Aircraft
Initially, H2GEAR will power aircraft with up to 19 seats, but it could be further developed for larger airliners later.

GKN Aerospace is to lead a collaboration between industry and academia to develop a new hydrogen propulsion system for small “sub-regional” aircraft. Initially, the H2GEAR system will power new and existing aircraft seating up to 19 passengers, but the aerospace group says it could subsequently be scaled up for use on larger airliners.

The UK-based project is backed by an evenly-shared £54 million ($73 million) joint investment by GKN, along with its partners and the government’s Department for Business, Energy and Industrial Strategy (BEIS). Program partners include fuel cell specialist Intelligent Energy, electric motors and control systems group Aeristech, Newcastle University, the University of Manchester, and the University of Birmingham.
