Water can be decomposed to hydrogen and oxygen AB A + B H 2 O (L) H 2 (g) + O 2 (g) 2 H 2 O (L) 2H 2 (g) + 1O 2 (g)
Power Supply Water
Water being decomposed by electricity
Hydrogen and Oxygen can be recombined by burning hydrogen A + B AB
Hydrogen burns with an almost invisible flame. Hydrogen + Oxygen == Water H 2 (g) + O 2 (g) == H 2 O(g)
Pure oxygen speeds up combustion since air is only 1/5 oxygen.
2 H 2 O( L ) 2 H 2 ( g ) + 1O 2 ( g ) Decomposition Synthesis ELECTROLYSIS COMBUSTION
