White Coal is high-temperature chemical processes can split water into hydrogen and oxygen through thermal treatment alone, without electricity input. Promising methods include sulfur-iodine thermochemical cycling and ceria-based water-splitting. Research in these second-generation thermochemical processes aims to make them commercially viable for large-scale hydrogen production. https://timessquarereporter.com/business/white-coal--an-alternative-energy-source-for-a-greener-future
