Abstract

Hydrogen seems to possess all the characteristics to store the excess of electrical energy produced during off-peak periods. Hydrogen energy storage plants could be environmentally non-polluting, easy to place, not sensible to load variation, unbounded in size, efficient and safe. These last two features seem to contradict one another. An option that could give a reliable solution is the storage of hydrogen in metal hydride and the storage of oxygen as a liquid. Such a choice is probably the safest one to make and allows the achievement of efficiencies comparable to those obtainable with gaseous storage of both electrolytic products. The power consumption for H2and O2storage is only 3% of the total energy stored and the charging ratio approaches the values obtained with hydro-pumped storage plants. © 1997 International Association for Hydrogen Energy.
