The 53 MWh storage project, made up of Element Energy''s retooled electric vehicle batteries, has been operating commercially, storing and dispatching power to the ERCOT grid, since May 2024.
The startup enabled the reuse of 900 EV batteries to make up the project by applying its proprietary hardware and software algorithms, which were developed to improve the safety, intelligence, and economics of large-format battery systems.
The company''s proprietary technology replaces a traditional power conversion system with a distributed power conversion approach for a more granular level of control. Instead of controlling a megawatt-hour scale battery as a single element with thousands of cells all subjected to the same use profile, Element''s technology independently controls the power flowing in and out of each module (tens of cells).
"We''re thrilled that our technology completes the circular supply chain for energy storage, while also making batteries safer. With our commercial project in West Central Texas, we have validated our technology at scale. We are now focused on deploying our growing supply of second-life batteries," said Tony Stratakos, CEO and co-founder of Element Energy.
In 2022, Element Energy received $7.9 million in funding from the U.S. Department of Energy (DOoE) to complete its 53 MWh commercial project. According to the DOE grant announcement, the project was deployed in cooperation with NextEra Energy Resources, which operates nearby wind facilities.
"This provides an opportunity for Element''s technology to be deployed in a real-world application on the grid, which is key to validating the viability and value proposition provided by Element''s unique technology," the DoE said at the time.

The developer enabled the reuse of 900 EV batteries to make up the grid-connected energy storage system. Element Energy''s technology has immediate and significant impacts for the growing global battery market.
“With our commercial project in West Central Texas, we have validated our technology at scale,” Element Energy CEO and co-founder Tony Stratakos said in a statement. “We are now focused on deploying our growing supply of second-life batteries."
Batteries for electric vehicles eventually reached the end of their useful EV life, but still possess about 80% of storage capacity, according to technology certification firm UL (Underwriter’s Laboratory). Most of this second-life EV batteries can be repurposed and connected for stationary power such as backup energy or grid services.
Element Energy was awarded $7.9 million by the U.S. Department of Energy to complete the commercial project. The funding was provided from the Bipartisan Infrastructure Law to support technologies and processes for second-life battery applications.
Element Energy has received and screened about 2 GWh of second-life batteries and plans to deploy the batteries for grid-scale projects. For the 2 GWh of batteries procured by Element Energy, approximately 8,500 metric tons of post-recycling waste and 150 metric tons of CO2 is expected to be avoided by reusing instead of recycling batteries.
The partnership would pair Element Energy’s containerized energy storage and battery management system with LG Vertech’s system integration, power equipment, software and maintenance services.
Element Energy has raised $111 million in capital comprising a $73 million Series B equity investment and a $38 million debt facility provided by Keyframe Capital Partners.
Other firms exploring second-life battery technology include Canadian startup Moment Energy. The company has secured a $20.3 million U.S. Department of Energy grant to build a manufacturing plant for repurposing EV batteries also in Texas.
