GE Research has been selected to receive $2.9 million to design, manufacture and test a composite tank capable of carrying 20 kg (44 lb.) of liquid hydrogen.
A study by German aerospace center DLR also shows that further reductions in climate impact are possible by switching to hydrogen as an aviation energy source.
GKN Aerospace, Marshall, and Parker Aerospace have signed an MOU to partner on development of a liquid hydrogen fuel system for future zero-emission aircraft.
