Low-pressure hydrogen bridges seasonal gaps in solar-powered Japanese building

Taisei Corporation has demonstrated that a building can operate entirely on solar power by combining PV generation with a hybrid storage system integrating batteries and low-pressure hydrogen at a test facility in Yokohama. An EMS-enabled setup using lithium-ion batteries and PEM electrolysis balanced short- and long-term energy supply and demand, enabling year-round renewable operation, according to the company.
