Exowatt, backed by Sam Altman, is developing solar-thermal technology to power AI data centres, aiming for electricity costs as low as one cent per kWh. The company's P3 system uses lenses to concentrate solar energy, storing it as heat in a thermal battery for on-demand electricity generation. This modular approach allows for scalable deployment and 24-hour power delivery, targeting industries with intensive energy needs.
Exowatt's system is designed to be cost-effective and reduce reliance on rare earth minerals. The company has secured significant funding, including a $70 million Series A round, to scale production and deploy its technology. Exowatt currently generates electricity at just under $0.04 per kWh, with a long-term goal of reaching $0.01 per kWh as production increases.
To achieve its ambitious goals, Exowatt plans to scale production to 1 million units annually, leveraging domestic manufacturing and strategic partnerships. The company's focus on US-sourced materials aims to mitigate supply chain risks and ensure resilience. Exowatt has a backlog of demand exceeding 90 GWh, primarily from data centres seeking sustainable and reliable energy solutions.
