Power to Gas (P2G) Technology
The KEPCO Research Institute plans to produce hydrogen at nuclear power plants using power to gas (P2G) technology, a researcher from the institute said on Oct. 28.
"In the future, there will be a way to produce high-efficiency hydrogen at nuclear power plants using idle power at night," the official said at the 2020 Green New Deal Expo held at Dongdaemun Design Plaza (DDP) in Seoul.
P2G technology produces hydrogen by electrically dissolving water through regenerated electricity.
In May, the government selected KEPCO for a project to develop P2G technology to produce and store green hydrogen.
The green hydrogen project aims to produce hydrogen by utilizing renewable energy. It has the advantage of solving the problem of surplus power generated by renewable energy and contributing to maintaining the stability of the power system.
The KEPCO Research Institute is also studying methanation, a process by which carbon monoxide and carbon dioxide and hydrogen are converted to methane and water. Its plan is to lead the methane to a city gas grid and use it for heating at home.
