Los Angeles-based B2U Storage Solutions and Korean battery giant LG Energy Solution have signed a strategic collaboration to build out gigawatt-hour-scale battery storage systems in the United States using LG's repurposed electric-vehicle battery packs.
The Deal At A Glance
Announced September 24, 2026, the agreement pairs B2U's EPS (Energy Pack Storage) architecture — which stitches used EV modules directly into utility-grade storage without heavy remanufacturing — with LG's stream of end-of-life passenger and commercial-vehicle packs. Neither company disclosed the initial contract value or a fixed volume, but they framed the pipeline as "GWh-scale."
What Each Side Brings
LG Energy Solution is the world's second-largest lithium-ion supplier by shipped GWh, with EV programs across the US, Europe, Korea and China. B2U, founded in 2019, already runs the largest operating fleet of second-life battery storage in North America and just brought its 28 MWh Bexar-Martinez BESS online near San Antonio, Texas. CEO Freeman Hall said the partnership is aimed at "unlocking the inherent value" of otherwise stranded EV batteries.
Customer Target: Data Centers
The two companies pointed at grid-scale utilities, storage developers and data centers as priority buyers — the same customer set B2U cultivated in an earlier Waymo robotaxi second-life partnership. Seung Tak Joo, LG Energy Solution executive, called the deal "an extension of our batteries' value beyond their original applications." Data-center demand, driven by AI workloads, is expected to add 60 GW of US load by 2030, and low-cost second-life BESS is one of the cheapest paths to peak-shaving that capacity.
Where This Sits In The Circular Battery Race
The pairing puts B2U into direct competition with battery recyclers such as Redwood Materials and Li-Cycle by keeping the pack — not just its raw materials — in service for another decade. It also complements LG's standalone GWh-scale LFP contracts with buyers such as Fluence.
