Liebherr and GM to Develop HYDROTEC Fuel Cell-based Electrical Power Generation System

Arun Sivasankaran - : Jun 21, 2021 - : 1:34 am

General Motors and Liebherr-Aerospace will collaborate on development of a HYDTROTEC hydrogen fuel cell technology-based electrical power generation system for aircraft applications.

The demonstrator will be based on GM’s HYDROTEC hydrogen fuel cell technology. The construction and testing of the demonstrator will take place in a specialized laboratory multi-system integration testing at Liebherr-Aerospace in Toulouse (France). The demonstrator will incorporate GM’s  fuel cells, HYDROTEC power cube and fuel cell system, along with the GM’s controls and models.

Fuel cells offer the advantages of lower emissions and lower noise than conventional aircraft operation. GM’s fuel cell business benefits from decades of investment in engineering and manufacturing expertise with high volume processes that can bring economies of scale to fuel cell production.

“Aircraft are a great litmus test for the strength and versatility of our HYDROTEC fuel cells,” said GM Executive Director – Global HYDROTEC Charlie Freese. “Our technology can address customer needs in a wide range of uses – on land, sea, air or rail, and this collaboration with Liebherr could open up new possibilities for aircraft, transitioning to alternative energy power sources.”

“The change from the conventional to a hydrogen technology-based electrical power generation system means major systems modifications on board the aircraft that could result in better, more efficient performance of the plane. This we want to prove and test thoroughly,” said Francis Carla, Managing Director and Chief Technology Officer, Liebherr-Aerospace & Transportation SAS. “The advantage of GM’s HYDROTEC fuel cell technology is that it has shown promise in extensive automotive and military programs, where it has shown to be reliable from the engineering and manufacturing perspectives. We are developing low emissions aerospace solutions.“
