A collaboration has marked a significant step in increased energy efficiency for the US Navy after evaluating the viability of using fuel cells in its underwater vessels.
General Motors (GM), the Office of Naval Research (ONR) and the US Naval Research Laboratory have been undertaking experiments to incorporate automotive hydrogen (H2) fuel cell systems into the next generation of Navy unmanned undersea vehicles (UUVs).
As part of the project, the Naval Research Laboratory has recently completed the evaluation of a prototype UUV with a GM fuel cell at the heart of the vehicle powertrain, marking a key step in the development of an at-sea prototype.
