EnerVenue says its ESVs can cycle two to three times a day without rest, have a 30-year, 30,000 cycle lifetime and 2-12 hour discharge rates, which if true makes it three to five times more durable than lithium-ion batteries – and with none of the thermal runaway risk of lithium-ion. Its Energy Racks are now available to order with shipping in 2024.

Randall Selesky, CRO, EnerVenue, said: “Stationary energy storage customers want easily scalable battery architecture, straightforward installation, and a high-density solution that takes up a minimal footprint.”

“The EnerVenue Energy Rack addresses these market needs head-on, offering a pre-engineered and assembled design that maximizes energy density while reducing integration and onsite installation labor costs. Our customers get complete flexibility to install and connect as many fully assembled Energy Racks as their energy storage use cases require—simple as that. We’re looking forward to the accelerated pace at which customers will be able to implement new energy storage operations and scale existing installations with our stackable rack units.”

The company’s battery design is based on a technology in use by NASA and others for outer space power applications.

The company last year claimed 5GWh of customer orders and this year started building a gigafactory in Kentucky, US, with an initial capacity of 1GWh rising eventually to 20GWh. Multi-state utility Dominion Energy recently announced plans to deploy EnerVenue’s tech in a pilot project.
