Abstract:
A process for the reversible storage of hydrogen, comprising bringing an alloy of alkaline metal and silicon into contact with gaseous hydrogen leading to the formation of the hydride or corresponding hydrides, comprises the use of at least one balanced system that corresponds to the formula: MXMSi MXMSiHn where M is selected from among Li, Na, or K and in which atomic ratios XM take on the following values: XLi=1 1≦XNa≦3 1≦XK≦2 n is the number of hydrogen atoms corresponding to the stoichiometry of the hydride or formed hydrides. or to the formula MSiXSi MSiXSiH2XSi+1 where M is selected from among Li, Na, or K and in which the atomic ratio XSi=Si/M takes on a value of 1 to 4.
