UK-based Electric Aviation Group (EAG) has launched a new subsidiary for developing megawatt-class fuel cell stack systems for its 90-seater hydrogen airliner called Hydrogen Hybrid-Electric Regional Aircraft (H2ERA).

The Smart Megawatt Stack (SMS) Fuel Cell Systems subsidiary will be engaged in the development of fuel cell stack systems that can be used for aerospace and non-aerospace applications.

This megawatt-scale fuel cell stack system will comprise four and six fuel cell stacks with a capacity to deliver 7MW to 8MW of power.

In addition to aircraft, the system can be deployed in heavy trucks, ships and trains.

EAG CEO Kamran Iqbal said: “The megawatt-scale fuel stack system to be developed by this new venture is yet another key step to make EAG’s aircraft a reality.

“Our aircraft and its enabling technologies will become a blueprint for future larger and smaller green aircraft. It is the foundation to secure a leading share in the sustainable mass transportation market.”

H2ERA will be equipped with 2MW electric motors, which is being developed by a joint venture (JV) between EAG and the UK’s University of Nottingham (UoN) called hydrogen hybrid-electric propulsion systems (H2EPS) Limited.

The agreement between EAG and the University of Nottingham was signed last month. H2ERA is expected to start operations in 2030. 

At the time of entering the partnership, the University of Nottingham, Research & Knowledge Exchange pro-vice-chancellor Dame Jessica Corner said: “The University of Nottingham has world-leading expertise in Electric Propulsion Systems development and this partnership is a great opportunity for UoN to deliver long-standing impact that demonstrates our commitment to developing technologies for environmental sustainability by developing and commercialising products with the potential of creating wider societal benefits, decarbonising the aviation sector and creating world-leading electric propulsion capabilities in the UK.”
