Photolytic hydrogen production methods utilise photocatalysis to split water into hydrogen and oxygen using the energy from sunlight. In theory, only light energy (photons), water, and a catalyst are required. The technology is still in its infancy and the hydrogen production efficiency is very low. WebHydrogen Production: Thermochemical Water Splitting. Thermochemical water splitting uses high temperatures—from concentrated solar power or from the waste heat of nuclear power reactions—and chemical reactions to produce hydrogen and oxygen from water. This is a long-term technology pathway, with potentially low or no greenhouse gas emissions. t shirts cotton women
