EnerVenue has started production at what it describes as the world’s first high-volume manufacturing line for its Aqueous Metal Cell (AMC) technology. The facility is located at the company’s Wujin site in Changzhou, China. Groundbreaking for the facility took place in April 2026, while the first conforming cell was produced at the end of September as scheduled. The new line is designed to manufacture EnerVenue’s fourth-generation Aqueous Metal Cells for energy storage applications.
The first phase of the facility has an annual production capacity of 250 MWh. EnerVenue plans to increase the capacity to 1 GWh in 2027 and reach multi-gigawatt-hour scale by 2028. The production line is expected to ramp up to its full rate through November. Once fully automated, it is designed to produce approximately 300 fourth-generation Aqueous Metal Cells per day.
The manufacturing facility covers around 20,000 square metres and has provision for a second phase of similar size. EnerVenue said the production stations are standardised so that additional capacity can be added by replicating them. The company also said every cell passes through 41 checks across 11 stations before leaving the facility. The manufacturing process uses a continuous flow from raw materials to finished cells, with automated equipment used across different production stages.
EnerVenue’s Aqueous Metal Cell is a water-based metal battery based on nickel-hydrogen chemistry. The company says it has re-engineered the chemistry using lower-cost materials for stationary energy storage applications. The cell is designed for up to 30,000 charge cycles, equivalent to up to three cycles per day over 30 years, according to EnerVenue. The technology uses a water-based electrolyte and does not use lithium.
The new manufacturing line will support EnerVenue’s product range, including the Energy Core, Energy Cube, Energy Rack and Energy Prism. The products cover applications ranging from distributed and telecommunications UPS systems to in-building and data-centre UPS, commercial and industrial storage, grid-connected applications and containerised energy storage. The Energy Prism is designed for containerised systems ranging from 600 kWh to 1 MWh.
EnerVenue has also signed its first multi-megawatt-hour commercial order for the technology. The order covers 26 Energy Prism containerised storage units with a combined capacity of 11 MWh for an oilfield in northern China. The systems will store electricity generated by an onsite solar array and supply it back to the operation. The first three units are scheduled to ship in December 2026, with the remaining 23 units planned to follow in March 2027. Cells produced at the Changzhou facility are already in service, including a fourth-generation AMC deployment operating in Jintan, Changzhou, since November 2025.
