About the Company

Exowatt is a technology company focused on revolutionizing solar energy for the demands of modern, energy-intensive industries, particularly those supporting artificial intelligence infrastructure. Their flagship product, the Exowatt P3, captures solar energy using proprietary Fresnel lenses and heat exchangers, stores it efficiently as heat in high-capacity batteries, and then converts it to electricity on demand through a unique heat engine. This approach addresses one of solar’s biggest limitations—intermittency—by providing up to 24 hours of dispatchable, baseload power, making it ideal for data centers, utility companies, and other sectors that require reliable, scalable, and clean energy solutions.

What sets Exowatt apart is its commitment to sustainability, American manufacturing, and economic advantage. Their systems are factory-built in the U.S. using abundant, low-cost materials and do not rely on rare earth minerals, ensuring secure supply chains and supporting domestic jobs. Exowatt’s modular design allows for rapid deployment, easy scalability, and minimal maintenance over a 30-year lifespan. Employees and partners can take pride in contributing to a company recognized for innovation—such as winning Fast Company’s 2025 Next Big Thing in Tech Award—and for helping industries meet growing energy demands while reducing environmental impact and carbon emissions.
