This work developed a performance-based methodology to design a mechanical exhaust ventilation system for explosion prevention in Li-Ion-based stationary battery energy storage systems (BESS).
By replacing the hazardous chemical electrolytes used in commercial batteries with water, scientists have developed a recyclable 'water battery' – and solved key issues with the emerging technology, which could be a safer and greener alternative.
Formed in partnership with Xcel Energy, NLR's wind-to-hydrogen (Wind2H2) demonstration project links wind turbines and photovoltaic (PV) arrays to electrolyzer stacks, which pass the generated electricity through water to split it into hydrogen and oxygen.
In 2024, around 125 new hydrogen refuelling stations were opened worldwide: 42 in Europe, around 30 in China, 25 in South Korea, 8 in Japan and 13 in North America.
