- The funding will support California-based Element’s 50MWh project with NextEra Energy Resources (NEER) at one of the latter’s wind farms in West Texas.
- The project will showcase Element’s technology in a real-world grid application and was one of five proposals using second-life energy storage systems.
The US Department of Energy (DOE) has provided US$7.9 million for a 50MWh battery energy storage project using second-life EV batteries in the ERCOT, Texas market, by Element Energy and NextEra Energy Resources. The funding will support California-based Element’s 50MWh project with NextEra Energy Resources (NEER) at one of the latter’s wind farms in West Texas.
Element Energy has developed a proprietary battery management system (BMS) that it claims unlocks the opportunity for mass deployment of second-life energy storage systems by overcoming two key challenges. These include providing enough performance and cycle lifetime guarantees to make the application commercially viable and promoting safety and the need to improve thermal runaway prevention. In addition, it said its proprietary tech replaces traditional power conversion systems (PCS) with a ‘cost neutral-architecture that distributes power conversion’. The project will showcase Element’s technology in a real-world grid application and was one of five proposals using second-life energy storage systems. A report commented, “Instead of controlling a megawatt-hour (MWh) scale battery as a single element with thousands of cells all subjected to the same user profile, Element’s technology independently controls the power flowing in and out of each module”.
RePurpose Energy also received US$6 million for its microgrid project using a second-life energy storage system which will specifically test its software for measuring the state of health (SOH) of such a system. Other recipients were Tennessee Technological University recipients of US$4.5 million for its development of mobile EV charging stations utilising second-life EV batteries. The University of Alabama will get US$4 million for its project looking at second-life systems using batteries with varying levels of degradation.
