US-based EnerVenue has launched its Energy Rack, a 150 kWh plug-and-play DC storage system using NASA-derived Aqueous Metal Cell technology. The company claims the metal-hydrogen battery platform offers up to 30,000 cycles, reduced thermal management requirements, and a 30-year design life for utility-scale applications.
US-headquartered metal-hydrogen battery manufacturer Enervenue has launched its Energy Rack, a plug-and-play DC storage block designed for utility-scale and commercial energy storage projects with expected lifetimes of 20 to 30 years.
The company said the new system is based on its Aqueous Metal Cell (AMC) technology, which combines long cycle life, high power capability, and safety characteristics designed to reduce system complexity.
The AMC chemistry was adapted from nickel-hydrogen battery technology originally developed by NASA and used in space applications for more than three decades. Unlike conventional lithium-ion batteries, the technology uses a water-based electrolyte, which EnerVenue said reduces the need for complex thermal management systems, auxiliary heating and cooling, and additional fire suppression equipment. The company said that under extreme operating conditions or mechanical abuse, the cells are designed to release steam through a pressure-relief mechanism rather than undergo thermal runaway or propagate fire.
