You step onto the windswept shores of Jeju Island and sense something big is brewing. More than that, it pulled in research institutes and eager developers to test microgrids, green hydrogen production pilots, and electric-mobility schemes. Game-Changer: Green Hydrogen Production at ScaleIf you thought hydrogen was still tomorrow’s talk, Jeju is making it today’s centerpiece. The island plans to ramp up green hydrogen production fivefold, targeting 60,000 tons a year by 2035. Smart Grids and Home Fuel CellsUnder the surface lies a high-tech smart grid weaving together wind, solar, green hydrogen production, and EVs.
