24/7 Solar Power for AI Infrastructure

Exowatt is an American renewable energy startup based in Miami, Florida, founded in 2023 by Hannan Parvizian and Jack Abraham. It’s pioneering a new approach to sustainable power by combining solar thermal capture with long-duration energy storage. 

Technology Overview: Capture, Store, Dispatch

• Solar Thermal Capture

  The Exowatt P3 uses specialized lenses to convert sunlight into high-temperature heat instead of electricity—leveraging a form of concentrated solar power with modular scalability.

• Thermal Storage (Heat Batteries)

  This heat is stored in proprietary high-density thermal batteries capable of retaining energy without phase-change degradation—offering durable and cost-effective long-duration storage.

• On-Demand Dispatch via Heat Engine

  When needed, the stored heat is converted to electricity through a heat engine—delivering reliable, dispatchable power around the clock, independently of sunlight.

Designed for AI and Beyond: Key Advantages

• Dispatchable Clean Energy

  Exowatt enables up to 24-hour renewable power, solving the intermittency problem of solar and meeting the demanding load profiles of AI infrastructure.

• Rapid, Modular Deployment

  Systems are built into 40-foot container modules, allowing fast onsite deployment—even behind the meter—without complex grid upgrades.

• Scalable & Made in the USA

  Designed for linear scaling as demand grows, the P3 is manufactured domestically using locally sourced materials.

• Economic Advantage

  The system targets ultra-low energy costs—potentially down to 1 cent/kWh—by avoiding rare-earth materials and tapping into favorable programmatic incentives.

• AI-Ready Energy Backbone

  Equipped with real-time control, automation, and a digital twin architecture, Exowatt’s systems adapt swiftly to dynamic power demands typical of AI and high-performance computing environments.

Growth & Market Impact

• Rapid Funding and Adoption

  After a $20 million seed round in early 2024 led by Andreessen Horowitz, Atomic, and Sam Altman, the company closed a $70 million Series A in April 2025—bringing total venture backing to $90 million.

• Surging Demand Pipeline

  Exowatt has secured intent from customers totaling over 90 GWh in potential deployment—a mix of data centers, hyperscalers, and industrial users.

Broader Significance

With AI infrastructure rapidly expanding, reliable and affordable clean energy is vital. Exowatt’s thermal-based, modular system offers a strategic solution—closing the gap between renewable potential and grid constraints—while aligning with climate goals and energy sovereignty.
