The Hydrogen Stream: Japanese researchers develop low-temperature hydrogen battery
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.
BYD unveils 14.5 MWh storage system, world’s largest yet
China’s EV giant has unveiled the 14.5 MWh DC “Haohan” single-unit DC block with record-breaking capacity to challenge next-generation energy storage market.
Making BESS warranties work: Contracts vs. reality
Striking a careful balance between technical limitations, market ambitions, and contractual realism in operating battery energy storage systems (BESS) is no easy task. Rigid battery warranties can often be a make-or-break factor in BESS asset management. As a result, many industry players now argue that adopting a more flexible approach to warranties could unlock greater value from these inherently flexible assets.
