Abstract
A hydrogen fuel storage composition is prepared by mixing and reacting, on an atomic proportion basis, one part of an alkali metal selected form the group of lithium, sodium or potassium with eight to 24 parts of carbon under conditions of temperature and pressure such that a fully-reacted alkali metal intercalated graphitic carbon composite is formed. When suitably prepared, such a composite can reversibly absorb ten percent or more of its weight of hydrogen gas.
