Development of Technology for Hydrogen Production from Water Electrolysis

  • KOGAS is active in R&D to demonstrate green hydrogen production in connection with renewable energy as part of our transition to eco-friendly energy from 2020.
  • Water electrolysis directly produces hydrogen from water using electricity, and it is eco-friendly since it does not emit greenhouse gases unlike use of fossil fuels.
  • The research team uses a water electrolysis facility that produces green hydrogen from wind power surplus in Jeju-do, a battery system for power storage, hydrogen storage system, and electricity and hydrogen charging stations
