EnerVenue launches 150 kWh nickel-hydrogen battery system
By GridDigest Editorial · August 4, 2026 · synthesized from 4 sources

US-based EnerVenue unveiled its Energy Rack, a 150 kWh plug-and-play DC storage system using NASA-derived Aqueous Metal Cell technology. The company claims the platform offers up to 30,000 cycles, reduced thermal management needs, and a 30-year design life for utility-scale applications.
EnerVenue, a California-based energy storage company, has introduced a new grid-scale battery product built on chemistry originally developed for space applications, marking the latest entrant in the growing field of long-duration and alternative storage technologies.
NASA Roots, Commercial Application
The new product, called the Energy Rack, is a 150 kWh direct-current storage system designed for utility-scale deployment. EnerVenue describes it as a plug-and-play unit, positioning it for relatively straightforward integration into grid infrastructure. The underlying technology is the company's Aqueous Metal Cell platform, which traces its origins to nickel-hydrogen battery research conducted by NASA. That heritage, the company says, informs the system's durability and operational characteristics.
Performance Claims
EnerVenue is marketing the Energy Rack around several headline specifications. The company asserts the system is capable of sustaining up to 30,000 charge-discharge cycles over its operational life—a figure substantially higher than the cycle counts typically associated with lithium-ion chemistries used in grid storage today. Alongside that, EnerVenue projects a design life of 30 years, suggesting the product could remain in service for multiple decades without replacement.
The company also highlights reduced thermal management requirements as a distinguishing feature. Thermal regulation represents a significant cost and complexity driver in lithium-ion battery deployments, and EnerVenue's claims, if validated at scale, would represent a meaningful operational advantage. The sources reviewed for this article do not include independent third-party verification of these performance figures.
Market Context
The launch reflects continued interest across the energy storage industry in chemistries beyond lithium-ion, particularly for applications that require long service lives or operate in environments where thermal control is challenging. Nickel-hydrogen technology has historically been associated with satellite and aerospace use rather than terrestrial grid storage, and EnerVenue's commercial push represents an effort to translate that space-proven chemistry into a cost-competitive utility product.
The 150 kWh capacity of the Energy Rack positions it as a modular building block rather than a standalone large-scale installation, consistent with a design philosophy that allows developers to scale deployments by combining multiple units. The plug-and-play framing suggests EnerVenue is targeting ease of installation as a differentiator, though the sources do not detail specific interconnection standards or compatibility requirements.
