▼ Summary
– EnerVenue has raised $300 million to scale production of its nickel-hydrogen batteries, which are adapted from proven aerospace technology for ground-based energy storage.
– The company’s batteries use a safe, water-based electrolyte and are designed for extreme longevity, enduring tens of thousands of charge cycles.
– It is expanding manufacturing in Changzhou, China, and establishing a regional headquarters in Hong Kong to target global markets.
– The investment comes amid surging demand for safe, long-lasting grid storage, driven by AI data centers and renewable energy growth.
– The company is backed by major investors including Aramco Ventures and has an exclusive distribution deal in mainland China with Towngas.
The nickel-hydrogen battery, a technology that has reliably powered satellites and space stations for decades, is now being positioned as a major contender for Earth’s power grids. A significant financial commitment is accelerating this transition. EnerVenue, a California-based energy storage startup, has successfully closed a $300 million Series B extension. This substantial capital infusion, led by Full Vision Capital, the family office of Hong Kong billionaire Peter Lee Ka-kit, brings the company’s total funding to $445 million. The funds are earmarked for scaling production of its unique metal-hydrogen energy storage systems.
Concurrent with the funding news, EnerVenue announced key leadership and strategic moves. The company appointed Henning Rath, a seasoned executive with experience scaling the German renewable firm Enpal, as its new global CEO. It also revealed plans, supported by the Hong Kong Investment Corporation, to establish a regional headquarters and innovation center in Hong Kong. Rath emphasized that the new capital is vital for advancing core technology, expanding large-scale manufacturing, strengthening supply chains, and growing the company’s global commercial footprint.
Founded by Stanford professor Yi Cui in 2020, EnerVenue’s core innovation is adapting proven aerospace battery chemistry for grid-scale storage. Its systems utilize a water-based electrolyte, a fundamental difference from the flammable solvents in conventional lithium-ion batteries. This design eliminates fire risk and allows operation in extreme temperatures from -40 to 50 degrees Celsius. The company’s value proposition centers on exceptional longevity and total cost of ownership, claiming its cells can withstand tens of thousands of charge cycles with minimal degradation, far exceeding typical lithium-ion performance.
This promise has attracted a formidable roster of investors. Backers include Aramco Ventures, the investment arm of Saudi Arabia’s state oil company, alongside NEOM Investment Fund, SAIC Capital, and IDG Capital. The company also has a strategic partnership in China, where Hong Kong and China Gas Company (Towngas) holds an exclusive distribution agreement. Peter Lee serves as chairman of Towngas, which is also a minority shareholder in EnerVenue.
The investment arrives as demand for long-duration energy storage surges, driven by renewable energy expansion and the soaring power needs of AI data centers. This creates a pressing need for safe, reliable alternatives to supplement lithium-ion technology. EnerVenue enters a competitive field that includes Form Energy’s iron-air batteries, vanadium flow batteries from firms like ESS Inc., and established solutions like pumped hydro.
EnerVenue’s immediate focus is its manufacturing facility in Changzhou, China. The goal is to activate a 250 MWh production line by 2026, scaling toward an ultimate target of one gigawatt-hour of annual capacity. Strategically, the company plans to use its new Hong Kong base to drive commercial expansion into the Asia-Pacific, Middle Eastern, and European markets, targeting utility-scale and industrial projects. After being named one of Time magazine’s top green tech companies in 2025, EnerVenue now faces the critical test of transforming its aerospace heritage and significant capital into a viable, large-scale challenger in the global energy storage arena.
