A Hydrogen ICE Vehicle Powered by Ovonic Metal Hydride Storage

Among the various alternative fuels, hydrogen is the only fuel, which is clean and sustainable. More importantly, if hydrogen is produced from renewable resources, virtually no CO₂ emissions are produced.

Texaco Ovonic Hydrogen Systems (TOHS) has converted a gasoline internal combustion engine (ICE) hybrid vehicle to a hydrogen vehicle using its advanced metal hydride storage. Compared to its gasoline counterpart, the converted vehicle demonstrated a reduction in CO₂ tailpipe emission of 220 grams per mile.

Ovonic metal hydride hydrogen storage systems consist of three critical elements: (1) an advanced metal hydride alloy, (2) an efficient heat exchanger and (3) a lightweight fiber wrapped pressure container. A 50 liter Ovonic metal hydride storage vessel installed in the vehicle provides a storage capacity of 3 kg hydrogen and a driving range of 130-150 miles.
