What B2U Storage Solutions does

B2U Storage Solutions, founded in 2019 by Freeman Hall and Mike Stern as a spin-off from Solar Electric Solutions, manufactures, develops, deploys, and operates grid-scale Battery Energy Storage Systems (BESS) built around its patented EV Pack Storage (EPS) technology. The EPS platform integrates end-of-first-life EV battery packs from multiple OEMs (Honda, Nissan, Tesla, GM, Ford, LG, Waymo) into standardized BESS cabinets without modification or disassembly, governed by an Energy Management System (EMS) and an AI-powered analytics engine. The Model BC-54 BESS product is a 2.5 MWh unit available in 2-hour and 4-hour configurations, UL9540 certified including UL9540A large-scale fire testing and NFPA compliant, with a public introductory price of $95/MWh after Investment Tax Credits.

The company has deployed approximately 83 MWh across five grid-connected projects powered by 4,000+ repurposed EV battery packs with 99% uptime since 2020, including the SEPV Sierra (8MW/32MWh, Lancaster CA, 2020), SEPV Cuyama (3MW/12MWh, Santa Barbara County CA, end of 2023), and Bexar Corilla (10MW/24MWh, Bexar County TX, end of 2025) projects selling power and grid services into CAISO and ERCOT wholesale markets. A 10MW/24MWh Bexar Martinez project broke ground in April 2026 with equipment delivered in June 2026, and a structured finance fund closed in December 2025 contains seven BESS projects totaling roughly 150 MWh.

B2U operates as a project developer and asset manager, generating revenue through wholesale market participation (capacity payments, energy arbitrage), OEM and fleet-operator battery repurposing services (notably a June 2026 strategic supply agreement with Waymo), and the management of structured-finance project vehicles alongside institutional capital partners. Target offtakers are ISOs (CAISO, ERCOT), utilities, data centers, and other large energy users; battery supply counterparties include Waymo, GM, Honda, Nissan, Tesla, Ford, and LG.

Revenue model

1. Grid Services and Energy Storage: B2U develops, operates, and owns battery energy storage projects that provide power and grid services to wholesale electricity markets (CAISO, ERCOT). Projects charge during excess renewable generation periods and discharge during peak demand, generating revenue through capacity payments and energy arbitrage.
2. Project Development and Financing: B2U acquires, designs, develops, and operates energy storage projects, providing financing opportunities alongside institutional capital partners. The company launched a $45M structured finance fund in December 2025 containing seven BESS projects, enabling project divestiture while retaining day-to-day management.
3. Battery Supply Agreements: Strategic supply agreements with fleet operators (e.g., Waymo) to repurpose retired EV batteries into grid storage, creating a sustainable pipeline for used batteries while capturing residual value before final recycling.

Broad incumbents

• Tesla Energy (Megapack): Tesla's Megapack business is the dominant US grid-scale BESS OEM with new LFP cells, integrated Powerpack/Megapack hardware, and direct utility and developer relationships. While Tesla uses new cells rather than second-life packs, it competes head-to-head with B2U for the same utility, ISO, and data-center BESS procurement opportunities.
• Saft (TotalEnergies): Saft is an established European battery manufacturer and grid-scale BESS integrator owned by TotalEnergies. It competes with B2U in utility-scale BESS project supply, EPC integration, and lifecycle services, with broader product breadth but a similar focus on grid and industrial energy storage customers.

Direct peers

• Fluence Energy: Fluence is a leading global BESS pure-play offering hardware, software, and services across grid-scale and behind-the-meter applications. It targets the same utility, ISO, and large-energy-user customers as B2U, although with new-cell systems rather than second-life repurposed EV packs.
• Stem Inc: Stem is a BESS-focused developer and AI-driven energy software provider serving commercial, industrial, and utility customers. It overlaps with B2U in BESS project development, AI-enabled energy management software, and revenue-stacking services for ISO market participation.
• Powin Energy: Powin is a US-headquartered BESS OEM offering containerized BESS solutions for utility-scale and C&I customers. Like B2U, it supplies turnkey containerized BESS units, integrates battery management and EMS software, and competes directly in grid-scale procurement with US-anchored manufacturing.
• Connected Energy: Connected Energy is a UK-based specialist in repurposing second-life EV batteries into grid-scale and EV-charging storage systems. It is one of the closest direct analogues to B2U globally, sharing the second-life repurposing thesis and targeting similar utility and fleet customers in a different geography.
• Smartville: Smartville is a US-based second-life EV battery storage developer that repurposes retired EV packs into commercial and grid-scale BESS. It directly mirrors B2U's second-life integration thesis and competes for similar utility, data center, and commercial storage customers.
• Energy Vault: Energy Vault develops and deploys utility-scale energy storage systems, including gravity-based and hybrid BESS solutions. It competes with B2U for grid-scale and behind-the-meter project opportunities with utilities, data centers, and large energy users.
• ESS Inc: ESS Inc manufactures iron-flow long-duration BESS for utility-scale applications and competes with B2U in grid-scale project development, ISO market participation, and behind-the-meter storage sales. It offers a different chemistry but addresses the same storage duration and use-case requirements.

Emerging players

• Form Energy: Form Energy is developing iron-air long-duration storage for utility-scale applications. While chemistry and duration differ, it competes for grid-scale procurement budgets and utility partnerships targeting renewable integration and reliability, overlapping with B2U's ISO-market value proposition.
