Designs for solar+storage+hydrogen systems in buildings

Designs for solar+storage+hydrogen systems in buildings German scientists have tried to determine whether a PV system linked to a small electrolyzer, a fuel cell, and lithium-ion batteries could fully power a grid-connected household. Their new proposal consists of a 6.8kW PV array, a 5kW electrolyzer, a 1.24kW fuel cell system, and battery storage. Researchers from …
