Repurposed EV Batteries Power New Texas Grid Storage

B2U launches 24 MWh project near San Antonio using used EV batteries

Posted

B2U Storage Solutions has broken ground on a new energy storage project east of San Antonio, marking its first Texas-based deployment. The facility will house around 500 used EV battery packs in 21 modular cabinets, delivering 24 megawatt-hours of storage capacity to support grid stability. This is B2U’s third grid-scale storage installation overall, following two operational sites in California that contribute a combined 40+ MWh to the state’s power infrastructure.

The move signals a shift in how utilities and developers are beginning to value second-life EV batteries—not just as a sustainable option, but as a commercially viable storage resource. Texas, in particular, presents a strategic growth area due to its ongoing energy demand spikes, renewable integration, and a highly active wholesale energy market.

According to Freeman Hall, CEO of B2U, “Expanding our footprint into Texas is a significant strategic milestone for B2U as well as a testament to the excellence and scalability of our technology platform.” He explained further that “As EV pack repurposing gains acceptance as a preferred source of batteries for the large and high-growth grid and industrial energy storage markets, B2U will continue to lead by deploying our bankable, safe and profitable technology to the grid, and expanding to industrial customers.”

B2U’s approach—leveraging its UL 9540-certified EPS platform—allows for direct deployment of used battery packs with minimal processing. This helps reduce project costs and speeds up integration timelines. Using proprietary AI software, B2U also fine-tunes energy dispatch and bidding strategies to enhance market participation and grid service delivery.

Repurposed Batteries Positioned for Growth in Energy Storage Sector

B2U’s expansion in Texas isn’t a one-off. The company is planning to bring three additional projects online within the next year, targeting 100 megawatt-hours of storage capacity statewide. By mid-2026, its total installed repurposed battery capacity—including current California installations—is expected to exceed 150 MWh.

This growth trajectory aligns with broader market forecasts. According to IDTechEx, repurposed EV batteries could contribute over 200 GWh in global grid storage capacity by 2035, as more electric vehicles reach the end of their road use. With millions of EVs entering retirement in the coming decade, the economics of reuse are beginning to shift from niche to mainstream.
