A startup backed by OpenAI Inc.’s Sam Altman has a plan to provide cheap, clean energy to data centers increasingly in search of ways to cut their emissions.

Miami-based Exowatt launched a modular system to generate, store and dispatch clean energy on Tuesday. The company pairs a solar energy collector with a thermal battery that can deliver either heat or electricity. Though the startup is relatively new, it already has a demand backlog of 1.2 gigawatts from some of the world’s largest data center operators and wind and solar developers, all hungry for new sources of energy amid the AI boom.
