This public note looks at Zelestium Technologies. European defence and technology circles are quietly taking notice of a small Spanish battery innovator with outsized ambitions. Zelestium Technologies, based in Soria, Spain, is developing advanced aluminium-ion and aluminium-air batteries – a novel class of “smart” energy storage systems designed to be safer, cleaner, and strategically self-reliant. Founded by veteran battery engineers, Zelestium’s mission initially sounds like a civilian green-tech venture: to revolutionize energy storage for smart grids and electric vehicles.
