- (ii) introducing ammonia into a reactor;
- (iii) contacting at least some of the ammonia in the reactor with a metal-containing-compound to form hydrogen;
- (iv) removing at least some of the hydrogen formed in step (iii);
- and
- (v) contacting the metal-containing-compound with further ammonia;
- wherein the metal-containing-compound comprises one or more of Li, Be, Mg, Ca, Sr, Ba or alloys or mixtures of two or more thereof;
- wherein the metal-containing-compound is selected from a metal amide, metal imide, metal nitride or combinations thereof;
- and
