Enervenue Raised $300M to Scale Its High Volume Manufacturing
Adam Harrie — May 8, 2026
EnerVenue raised a $300 million Series B extension, led by Full Vision Capital, to accelerate high-volume manufacturing of its aqueous metal cell long-duration energy storage systems. The capital targets 250MWh in the short term and 1GWh in the medium term, with manufacturing scaling in Changzhou, China, alongside continued R&D in Silicon Valley.
The company’s technology focuses on durability and safety over short-term optimization, targeting utility, commercial and industrial storage applications where infrastructure-grade reliability is critical. EnerVenue is also planning commercial expansion across Asia, the Middle East and Europe in the coming months.
As energy grids demand more reliable long-term storage, EnerVenue shows how battery technologies designed for long-term cycling and reliability can attract significant institutional capital as energy storage scales globally.
