General Motors, the Office of Naval Research and the U.S. Naval Research Laboratory are cooperating to incorporate automotive hydrogen fuel cell systems into the next generation of Navy unmanned undersea vehicles, or UUVs.

Hydrogen fuel cells convert high-energy hydrogen efficiently into electricity, resulting in vehicles with greater range and endurance than those powered with batteries. Under the ONR’s Innovative Naval Prototype program for Large Displacement UUVs, energy is a core technology in the Navy’s goals for vehicles with more than 60 days endurance.

The Naval Research Laboratory recently concluded an evaluation of a prototype UUV equipped with a GM fuel cell at the heart of the vehicle powertrain. The tests were conducted in pools at the Naval Surface Warfare Center in Carderock, Md.

“Our in-water experiments with an integrated prototype show that fuel cells can be game changers for autonomous underwater systems,” said Frank Herr, ONR’s department head for Ocean Battlespace Sensing. “Reliability, high energy, and cost effectiveness — all brought to us via GM’s partnering — are particularly important as Navy looks to use UUVs as force multipliers.”

“The collaboration with the Navy leveraged what we learned in amassing more than 3 million miles of real-world experience with our Project Driveway fuel cell program,” said Charlie Freese, executive director of GM Global Fuel Cell Activities. “Our customers will benefit from additional lessons we learn about the performance of fuel cells in non-automotive applications that will be useful in GM’s drive to offer fuel cells across consumer markets.”
