Exowatt builds the P3, modular dispatchable energy systems designed for AI infrastructure and other energy-intensive applications. The system captures solar energy using proprietary Fresnel lenses and heat exchangers, stores it as heat in a high-efficiency battery capable of extended storage with minimal losses, and generates electricity on demand through a proprietary heat engine, providing up to 24 hours of dispatchable power. It serves utility companies needing grid strengthening with dispatchable energy and long-duration storage, as well as data centers requiring onsite, on-demand power. Systems deploy rapidly with or without grid interconnection, are factory-built for easy installation and minimal maintenance over a 30-year lifespan, and are manufactured in the USA from domestically sourced materials. The technology offsets carbon emissions using solar energy without rare earth minerals.
