Answer: Hydrogen and Oxygen (H2O)

In photosynthesis water molecules are split into ____ and ____ atoms. Water splitting is the chemical reaction in which water is broken down into oxygen and hydrogen: 2 H2O → 2 H2 + O2 Efficient and economical water splitting would be a technological breakthrough that could underpin a hydrogen economy. A version of water splitting occurs in photosynthesis but hydrogen is not produced. The reverse of water splitting is the basis of the hydrogen fuel cell.

Electrolysis of water is the decomposition of water (H2O) into oxygen (O2) and hydrogen (H2) due to an electric current being passed through the water. • Vion U.S. Patent 28 793 "Improved method of using atmospheric electricity" June 1860.

In power to gas production schemes the excess power or off peak power created by wind generators or solar arrays is used for load balancing of the energy grid by storing and later injecting the hydrogen into the natural gas grid. Production of hydrogen from water is energy intensive. Potential electrical energy supplies include hydropower wind turbines or photovoltaic cells. Usually the electricity consumed is more valuable than the hydrogen produced so this method has not been widely used. In contrast with low-temperature electrolysis high-temperature electrolysis (HTE) of water converts more of the initial heat energy into chemical energy (hydrogen) potentially doubling efficiency to about 50%. Because some of the energy in HTE is supplied in the form of heat less of the energy must be converted twice (from heat to electricity and then to chemical form) and so the process is more efficient.
