Research

Devices that convert chemical energy from a fuel into electricity through an electrochemical reaction, producing minimal emissions.

Crucial components for storing hydrogen, either as compressed gas or supercooled liquid, which are necessary for powering hydrogen-based vessels.

Cryogenically stored hydrogen maintained at -253°C in a vacuum-insulated tank, offering 2.8 times more energy density than gaseous hydrogen for aviation applications.
