EnerVenue begins mass production of long-life water-based batteries

California-based company EnerVenue has launched the world’s first large-scale production line for its Aqueous Metal Cells (AMC). These water-based batteries utilize nickel-hydrogen chemistry, a technology previously used in the Hubble Space Telescope and the International Space Station, but redesigned with lower-cost materials for terrestrial use.

The primary advantage of the AMC technology is its extreme longevity. The cells are designed to withstand 30,000 charge and discharge cycles, supporting a projected lifespan of 30 years even with three cycles per day. EnerVenue claims the system does not require scheduled capacity reinforcements to compensate for degradation over its lifetime.

The initial phase of the production facility has a nominal capacity of 250 MWh per year. The company aims to scale production to 1 GWh by 2027 and several gigawatt-hours annually by 2028. Once fully automated, the production line is expected to manufacture approximately 300 fourth-generation cells per day.
