Unlike petroleum, it can be easily generated from renewable energy sources. It is also nonpolluting, and forms water as a harmless byproduct during use. Yet it is so difficult to store that its use as a fuel has been limited.

A gram of hydrogen gas occupies about 11 liters (2.9 gallons) of space at atmospheric pressure, so for convenience the gas must be intensely pressurized to several hundred atmospheres and stored in a pressure vessel. In liquid form, hydrogen can only be stored under cryogenic temperatures. These options are not practical for everyday use.

The solution to these difficulties is storage of hydrogen in hydride form. This method uses an alloy that can absorb and hold large amounts of hydrogen by bonding with hydrogen and forming hydrides. A hydrogen storage alloy is capable of absorbing and releasing hydrogen without compromising its own structure.

GfE Gesellschaft für Elektrometallurgie mbH-An essential element for an environmentally friendly energy supply of the future is the use of hydrogen as an energy source. GfE has developed alloys that are able to store hydrogen chemically as hydrides. In this way, hydrogen can be stored safely. These hydride tanks are particularly used as the energy supply for PEM fuel cells.

Successful tests series have been conducted with forklift trucks, boats, scooters and laptops powered such storage systems.

The sale of our materials as well as the sale of complete storage systems is the responsibility of our joint venture company, HERA. www.herahydrogen.com
