Exowatt is an American renewable energy company founded in 2023, headquartered in Miami, Florida. The company develops modular solar thermal energy systems (Exowatt P3) that capture solar heat, store it in long-duration thermal batteries, and dispatch electricity on demand (up to 24/7). Exowatt targets energy-intensive applications like AI data centers, commercial/industrial sites, and high-power loads, emphasizing low-cost, dispatchable clean energy without reliance on rare earth minerals or complex supply chains. Backed by investors including Sam Altman, Andreessen Horowitz, Leonardo DiCaprio, and HSBC, Exowatt raised $140M+ by 2025 for U.S. deployments. While early plans included cryptocurrency mining support (e.g., West Texas facility mentioned in 2024), current focus is AI/hyperscale data centers with no prominent ongoing mining activities.
