Antora Energy, a long-duration energy storage startup, has raised USD 150 million in a Series B funding round led by Decarbonization Partners. This brings the company's total funding to USD 205.5 million.

The company intends to use the funds to scale the production of its thermal batteries in preparation for delivery to customers.

Other participants in the funding round included new investors Emerson Collective, GS Futures, The Nature Conservancy, and a subsidiary of NextEra Energy Resources, while existing investors Trust Ventures, Lowercarbon Capital, Breakthrough Energy Ventures, BHP Ventures, Overture VC, and Grok Ventures also participated in the round.

Analyst QuickTake: Antora last raised funding in November 2023 , when the company received a grant of over USD 4 million from the California Energy Commission (CEC) and the Department of Energy’s Advanced Research Projects Agency-Energy. Antora intended to use the funds to scale up its thermophotovoltaic technology, which stores renewable power as heat in blocks of solid carbon. Prior to this, in September 2023 , Antora launched its first commercial-scale system at a facility in Fresno, California. The company intends to begin shipping its battery systems to clients in 2025.
