A new process for storing hydrogen may solve the major problem of how to store and transport the fuel of the future.
Researchers at the Technical University of Denmark have developed a simple, cheap process which is being further developed and commercialized by Amminex A/S. Hydrogen is stored as ammonia in common salt. Ammonia is hydrogen combined with nitrogen from the air. Once the hydrogen is converted to ammonia it is stored in the salt material until needed. The salt block is safe and not subject to explosion or leakage. The amount of hydrogen stored in a block the size of a auto gas tank can fuel a ordinary car for a 600 km trip. This is the first method of safely storing hydrogen that compares to ordinary gasoline in energy density. A catalyst releases the hydrogen as needed. Refuel the salt block by absorbing a new load of ammonia. For further information, see articles at Amminex: A 2007 slide show pdf in english everything else seems to be from 2005.
