About the company
Eos Energy Storage develops and manufactures aqueous zinc battery energy storage systems for commercial, industrial, utility, and renewable energy customers. The systems store electrical energy in an aqueous zinc chemistry and are designed for 3 to 12 hours of use to support grid resiliency, peak shaving, demand management, and intermittent renewable generation. The products are modular battery packs with simplified components aimed at reducing production costs and risks while delivering reliable storage for microgrids and large-scale projects. Compared with typical lithium-ion approaches, Eos focuses on a different chemistry and a streamlined design to provide cost-effective, safe energy storage for grid applications. The company’s goal is to accelerate the transition to clean energy by enabling reliable, affordable storage that boosts grid reliability and supports renewable integration.

1%Eos Energy Enterprises, a $1 billion AI infrastructure company, has caught attention for its zinc-powered battery systems targeting data centres. The technology offers advantages over lithium-ion batteries, including better fire safety, durability, and no active cooling requirements. The company reported 351% year-over-year revenue growth to $68.8 million in Q2, with an $807 million backlog including clients like the US Department of Defense and Alphabet. However, it faces significant challenges, including an $83.8 million Q2 operating loss and potential dilution from 56.5 million shares registered for resale by existing shareholders. Eos Energy is expanding manufacturing capacity at its Thorn Hill site, expected to complete in Q1 2027. Full-year revenue guidance was narrowed to $300-350 million due to production line consolidation timing.
Eos Energy Enterprises has received an $87 million advance under its loan agreement with the US Department of Energy's Office of Energy Dominance Financing. The advance reimburses 80% of eligible costs for the company's Thorn Hill manufacturing facility in Warrendale, Pennsylvania. Eos has now drawn approximately $178 million from its DOE facility since 2024. The company's second production line entered commercial production in June 2026 and is ramping toward its designed annual manufacturing capacity of approximately 2 GWh. Upon completion of the planned relocation of line 1 to Thorn Hill, the facility is expected to support approximately 4 GWh of annual manufacturing capacity across two lines. Eos designs and manufactures zinc-based long-duration energy storage systems in the United States.
Google is partnering with Eos Energy and MN8 Energy to build the Mammoth Solar project in West Virginia, representing a capital investment of up to $350 million. The facility will power Google's regional data centres, including an upcoming West Virginia facility. The project combines 86 MW of solar power with hybrid battery storage: 70 MW/280 MWh lithium-ion and 10 MW/100 MWh of Eos's Z3 zinc-based long-duration storage system. This marks Google's first deployment of Eos's Z3 technology. Eos Energy, trading at approximately $4 per share with a $1.5 billion market cap, could benefit significantly from the partnership. The project represents the first deployment under a 750 MWh master supply agreement between MN8 and Eos signed in October 2025. However, Eos's financials show substantial losses. Whilst revenue grew from $5 million in 2021 to $114 million in 2025, net losses expanded from $124 million to $970 million over the same period.
Bloom Energy and Eos Energy Enterprises both serve the growing energy infrastructure sector, but target different markets. Bloom provides onsite power through solid oxide fuel cell technology for data centres and utilities, whilst Eos offers zinc-based long-duration energy storage for renewable energy grids. Bloom reported revenue exceeding $2 billion in fiscal 2025, representing approximately 37% growth, though it posted a net loss of roughly $88.4 million. The company maintains partnerships including a $5 billion financing framework with Brookfield. Eos achieved revenue of approximately $114.2 million in 2025, a 630% increase year-over-year, but reported a significantly wider net loss of nearly $1.75 billion as it ramped up commercial manufacturing. Both companies face distinct risks. Bloom contends with pending securities litigation and supply chain dependencies linked to China. Eos confronts ongoing losses, reliance on external capital, and competition from larger battery manufacturers. For 2026, Bloom expects revenue to leap 85% to $3.75 billion, driven by AI data centre demand. Eos projects revenue to more than double, with management citing a $25 billion business pipeline.
Eos Energy Enterprises reported a Q2 2026 net loss of $276 million, primarily from non-cash fair value adjustments of warrants and derivatives. The company tightened its 2026 revenue guidance to $300 million to $350 million due to manufacturing downtime during facility consolidation. Management is accelerating the consolidation of production into its Thorn Hill facility, which is expected to reduce conversion costs by 10% to 15% with a nine-month payback period. The company achieved record cube shipments and a 20% sequential output increase at its Turtle Creek facility whilst maintaining flat labour costs. Eos expects a 72-point improvement in adjusted gross margin over the next 12 months through material cost reductions and manufacturing efficiencies. The company anticipates closing the second year tranche of its advanced request loan by the end of Q3.
