Institute of Science Tokyo researchers proposed a battery with magnesium hydride (MgH2) as the anode and hydrogen (H2) gas as the cathode. Meanwhile, researchers at Chung-Ang University proposed chloride-resistant ruthenium (Ru)-based nanocatalysts for direct electrolysis and hydrogen production from seawater. September 19, 2025 Sergio Matalucci Japanese researchers developed a solid hydrogen battery that operates at 90 °C, achieving reversible hydrogen gas absorption and release. The battery,...
