en.Wedoany.com Reported - Enervenue has made new progress in metal-hydrogen battery energy storage technology. The company completed a $300 million Series B financing in March this year and appointed Henning Rath, a former executive at German company Enpal, as CEO. Rath recently told ESS News in a phone interview from the semi-automated production line at its new Changzhou factory that the next step is to launch a fully automated production line for the fourth-generation chemistry system, with a capacity of 250 MWh, scheduled to begin production in the third quarter, followed by an expansion to 1 GWh by 2027.
Enervenue has partnered with Hong Kong utility company Towngas (The Hong Kong and China Gas Company) to launch the first pilot project for the fourth-generation technology. The project uses a customized AC module containing 50 Enervenue aqueous metal batteries (AMCs), providing a total energy storage capacity of 150 kWh in a modular rack configuration, equipped with a battery management system (BMS) and inverter, installed in a customized outdoor-grade enclosure. The site also features renewable energy generation and an electric bus charging station.
According to Rath, Enervenue is deploying more pilot projects in the United States, Canada, Australia, Belgium, and Saudi Arabia. The company aims for a global footprint and wants to participate in every stage from manufacturing to deployment. Currently, the company has not yet established distribution centers but ships containers up to 40 feet long to work sites on a FOB China basis. Rath stated that Enervenue is emulating Tesla's business model, which is "mature and vertically integrated."
Enervenue is building its manufacturing base in Changzhou, which Rath describes as "China's battery hub," suitable for large-scale manufacturing. The company is learning how to manufacture at scale and then replicate the approach in local markets. Meanwhile, the R&D team at the company's California headquarters has begun developing next-generation metal-hydrogen battery technology. Rath noted that Silicon Valley boasts incredible innovation capabilities, while China is an ideal place for rapidly iterating manufacturing infrastructure. The company positions itself as a global enterprise, with R&D in the U.S. and manufacturing in China.
Enervenue's battery chemistry consists of nickel, steel, and some gas-fiber composite materials, which are almost entirely recyclable with high residual value, involving no rare earths or lithium supply chain. The technology originated from NASA and Stanford University in the U.S., with a nickel-hydrogen chemistry system known as aqueous metal batteries, comprising a nickel hydroxide cathode and a nickel alloy anode in an alkaline electrolyte. During charging, hydrogen is generated and stored inside the sealed large-format battery, and the hydrogen reaction reverses during discharge. The battery has a round-trip efficiency of 90% and can be charged and discharged 30,000 times.
Enervenue is targeting the data center market, with its chemistry being safe and durable, suitable for long-duration energy storage with discharge times of 2 to 12 hours. The company will also enter the flow battery market and the petrochemical plant sector. Rath stated that he remains involved with Enpal, having previously served as its Chief Supply Chain Officer.
