Jang Seong-ho, head of hydrogen energy research at Korea Electric Power Research Institute, was a speaker at the ’14rd Hydrogen Market Insights (H3 Market Insights H2MI)’ domestic P2G demonstration session held at EXCO (CEO Lee Sang-gil) in Daegu on the 2th and said, ‘MW class water electrolysis system’ Establishment of test bed.
Jang Seong-ho, head of the research department, introduced the Korea Electric Power Research Institute’s New Energy Technology Research Institute and presented solutions to expand renewable energy. Research Director Jang said, “The phenomenon of drastic decrease in net load during the daytime due to excessive supply of renewable energy, the possibility of large-scale power outages due to the deterioration of system inertia, possible occurrence of output restrictions due to regional bias, and Jeju Island’s output limit of 40 times a year are problems that need to be resolved.” said.
Then, the 2MW class P2G task was introduced. P2G technology refers to a technology that produces hydrogen from fossil fuels and renewable energy, stores and transports the produced hydrogen, burns it directly, or produces electricity and heat through fuel cells.
The 2MW hybrid water electrolysis test bed mentioned by Director Jang consists of a water electrolysis integrated control room, an alkaline power converter, a cooling tower and DI supply facility, a PEM power converter, PEM water electrolysis, and ALK water electrolysis.
Research Director Jang said, “As for the first-phase technology development achievements, there are ‘MW class zero-gap stack and system development’ and ‘catalyst reduction technology and MW class system development’.” “1MW class hybrid water electrolysis system maximizes the use of renewable energy It is a doable solution.”
The system is a method in which alkaline and polymer membrane water electrolysis modules are linked. Experts expect high-efficiency and large-capacity green hydrogen production to become a reality.
