Claims40
A process for reversibly absorbing hydrogen, wherein a metal-nitrogen compound or a metalloid-nitrogen compound further comprising a dopant is contacted with a hydrogen containing atmosphere, at a temperature and under a hydrogen pressure which permits hydrogen absorption.
A hydrogen reservoir containing a metal-nitrogen compound or a metalloid-nitrogen compound combined with a dopant that bears absorbed hydrogen or is capable of bearing absorbed hydrogen.
A process for reversibly absorbing hydrogen, wherein Li2NH, a Li-enriched lithium imide, a ternary or higher nitride based compound or Ca2NH is contacted with a hydrogen containing atmosphere, at a temperature and under a hydrogen pressure which permits hydrogen absorption.
A hydrogen reservoir containing Li2NH, a Li-enriched lithium imide, a ternary or higher nitride, or Ca2NH, that bears absorbed hydrogen or is capable of bearing absorbed hydrogen.
