White Coal: A Renewable Energy Source for the Future

Posted 2025-02-10 10:06:28

Hydrogen has earned the nickname "white coal" due to its potential as a clean-burning alternative to fossil fuels. Like coal, hydrogen can be used as an energy carrier, but it produces only water vapor when burned, not greenhouse gases or other pollutants. This gives hydrogen advantages over traditional coal and makes it an appealing renewable energy solution.

White Coal a process called electrolysis, an electric current can be passed through water to split the H2O molecules into oxygen and hydrogen gas. Electrolysis uses renewable electricity from sources like solar, wind, or hydro power to operate, making the hydrogen production renewable as well. As renewable power generation technologies advance, electrolysis is becoming more efficient and cost-effective.

Some 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.
