What Inlyte Energy does
Inlyte Energy is a US-based, venture-backed developer and manufacturer of iron-sodium (sodium metal chloride) battery energy storage systems for grid-scale and industrial applications. The company was founded in 2021 by Antonio Baclig, a former Stanford researcher, and is headquartered in San Leandro, California, with additional engineering and manufacturing operations in Burton-on-Trent and Derby, United Kingdom, inherited from its November 2022 acquisition of Beta Research Ltd., a pioneer with over 40 years of sodium metal chloride chemistry experience. The core technology uses abundant raw materials (powdered iron and table salt) to deliver long-duration (8+ hour) energy storage with claimed 83% round-trip efficiency, over 7,000 charge cycles, and a 20-year operational lifespan, targeting a levelized cost of storage under $0.05/kWh.
The company's go-to-market is enterprise field sales targeting utility-scale grid operators, data center operators, and critical infrastructure / commercial-industrial customers. Operational milestones include an 80 kW / 1.5 MWh demonstration project with Southern Company planned for Q1 2026 installation in Alabama, a 600 kWh pilot with NTS Colocation AG in Switzerland targeted for late 2026 and scaling to 2 MW by 2028, and a DOE-funded community resilience deployment at Alliance Redwoods Conference Grounds in Northern California. Inlyte has signed a strategic manufacturing partnership with HORIEN Salt Battery Solutions to scale US production, targeting 2 GWh/year capacity in 2027 and 20 GWh/year by 2029, with commercial deliveries planned for 2027. The company reported over $100 million in customer letters of intent and has assembled a leadership team including executives hired from GE and Tesla to drive commercialization.
As of the latest data, Inlyte Energy remains pre-revenue, having completed factory acceptance testing of its first full-scale battery storage system in December 2025 but not yet commenced commercial deliveries. Capital sources include an $8 million seed round led by At One Ventures in October 2023, approximately $8.1 million in DOE grants, and selection for the NATO DIANA 2025 cohort. The company operates with 11-50 employees across its US and UK sites.
