Defense

Silent, low-signature and long range power for drones

Compact, lightweight fuel cell power with a low acoustic and thermal signature, for critical missions on land, in the air and at sea

Drones need better stealth  

Drones are now a major part of defense and surveillance missions. They demand power for long-distance flight with limited detection - in a compact format. Existing solutions have constraints on range, duration and detection, forcing compromises on thermal footprint or endurance.

EH Energy for defense

EH Energy supplies fuel cell stack and power systems at the heart of hydrogen defense platforms, from unmanned aircraft and ground systems, to marine and expeditionary power. Our compact, patented stacks with a scalable form factor deliver market-leading power density and endurance and convert hydrogen electrochemically for a low acoustic and thermal signature. Because our fuel cells can be modified quickly through our proprietary automated production, we tune stacks to each platform’s power, weight, endurance and altitude targets and take them from prototype to fielded fleet as a true partner.
