EnerVenue develops Aqueous Metal Cell (AMC) energy storage systems that use a water-based electrolyte and a proprietary catalyst to provide long-duration, lithium-free storage. Its fourth-generation cells are rated for a 30,000-cycle design life and offer discharge durations up to 12 hours, targeting grid-scale storage, renewable shifting, and critical infrastructure applications. The technology traces origins to NASA nickel-hydrogen batteries and Stanford research, and EnerVenue has achieved UL1973 and IEC63115-2 safety certifications. The company reports pilot projects in China, Australia, the United States, and the European Union. EnerVenue is transitioning from advanced developer to high-volume manufacturer, planning a 250 MWh production line in Changzhou with a mid-term 1 GWh target, while keeping R&D operations in Silicon Valley. Recent financing and leadership changes — including the appointment of CEO Henning Rath — are intended to support its manufacturing scale-up and global commercial expansion.
