Antora Energy, specializing in thermal battery solutions for data centers, has successfully raised $550 million in a Series C funding round. Co-led by G2 Venture Partners and Eclipse, this financing included prominent investors such as Decarbonization Partners, Lowercarbon Capital, and Breakthrough Energy Ventures. Since its founding in 2017, Antora, based in San Jose, California, has now raised $770 million. The fresh capital will accelerate large-scale battery storage projects nationwide to address the rising energy demands fueled by AI growth. Antora recently commissioned a 5-gigawatt-hour thermal battery system in South Dakota, one of the largest globally, using innovative technology that stores electricity as heat in solid carbon blocks to provide continuous clean energy. The company’s factory-built modules are versatile, serving industries like chemical, food production, steel manufacturing, and data centers without reliance on scarce minerals or long construction times. CEO Andrew Ponec emphasizes that Antora’s approach can break energy supply bottlenecks and support industrial expansion with American innovation. This funding round represents a significant cleantech investment amidst a period of modest venture activity in the sector.
