Water is decomposed to molecular hydrogen and molecular oxygen in a thermochemical cycle which comprises (i) reacting Cl2, Br2 or BrCl with water to obtain oxygen and hydrogen halide; (ii) forming a graphite intercalation compound with a hydrogen halide from step (i) and a metal halide selected from MBriCl3-i, wherein M is aluminum, gallium or indium and i is 0, 1, 2 or 3, and thereby obtaining hydrogen; (iii) decomposing by heating the graphite intercalation compound formed in step (ii); (iv) recycling the halogen produced in step (iii) for use in step (i); and (v) recycling the metal halide and graphite produced in step (iv) for use in step (ii).
