Abstract

1503850 Energy storage employing metal hydrides UNITED STATES ENERGY RESEARCH & DEVELOPMENT ADMINSTRATION 23 July 1976 [19 Aug 1975] 30848/76 Heading C1A [Also in Divisions C7 and F4] A method for storing energy comprises: (a) heating a first "metal" hydride 16 to an "effective decomposition temperature", said hydride having a decomposition pressure of 100 to 2280 mm of Hg at temperatures of from 100‹ to 300‹ C. and a standard heat of formation of 12 to 17 kilocalories per mole of hydrogen, whereby said hydride absorbs thermal energy and decomposes to form a first hydridable "metal" and hydrogen gas; (b) contacting the hydrogen gas with a second hydridable "metal" 22 while maintaining said second metal at a temperature below the "effective decomposition temperature" of the "metal" hydride being formed, thereby forming a second "metal" hydride, said second hydride having a decomposition pressure of from 760 to 2280 mm Hg at a temperature of 0‹ to 25‹ C. and a standard heat of formation of from 25 to 75% that of said first "metal" hydride per mole of hydrogen, whereby thermal energy is released as said hydride is formed; and (c) recovering said thermal energy. The stored energy may be released by: (d) cooling the first hydridable "metal" to a temperature below the "effective decomposition temperature" of the first "metal" hydride; (e) supplying heat to the second "metal" hydride to maintain said hydride at an "effective decomposition temperature" whereby said "metal" hydride absorbs thermal energy and decomposes to form a second hydridable "metal" and hydrogen gas; (f) contacting the hydrogen gas with the first hydridable "metal" while maintaining the first "metal" at a temperature below the "effective decomposition temperature" of the hydride being formed, thereby forming a "metal" hydride and releasing thermal energy; and (g) recovering said thermal energy. The term "metal" pertains not only to single metals but also to suitable alloys. The "effective decomposition temperature" is the temperature at which the "metal" hydride to be decomposed releases hydrogen gas at a usable rate. The first metal hydride may be heated indirectly using a solar energy collector 10 and a heat transfer loop 12, or directly either in a sealed container acting as a flat plate collector irradiated by sunlight, or by residual heat in stack gases. The first "metal" hydride may be MgNiH 4 . The second "metal" hydride may be LaNi 5 H 6-7 , SmCo 5 H 2À5 or FeTiH 1À95 .
