Antora Energy Secures $550 Million Series C to Scale Thermal Battery Deployment for AI Data Centers

Antora Energy announced a $550 million Series C funding round co-led by G2 Venture Partners and Eclipse to scale deployment of its thermal battery systems across the country. The company, which stores electricity as heat in insulated carbon blocks and delivers it as heat or power, is addressing the energy bottleneck constraining AI data center growth. With the funding, Antora has raised $770 million since its 2017 founding. The company recently completed one of the world's largest battery storage projects, a 5 gigawatt-hour system in South Dakota. Antora claims its modular technology can serve data centers, chemical plants, food producers and steelmakers without requiring rare minerals or years-long construction timelines, positioning it as a scalable solution to meet the surging energy demands of the AI infrastructure buildout.
