On July 20, 2026, Antora Energy finalized a $550 million Series C funding round, pushing its valuation to approximately $2.47 billion. This injection of capital will accelerate production of their modular thermal batteries, key for energy-intensive sectors such as data centers and heavy industry.
Antora’s batteries work by storing excess renewable electricity energy generated when the sun shines or wind blows to heat solid carbon blocks to extremely high temperatures. These blocks then release stored heat and power on demand, offering a reliable energy source that smooths out the intermittency of renewables.
For data centers, which depend on continuous, uninterrupted power, this technology is a big deal. As AI and cloud computing workloads surge, the demand for stable and clean energy sources grows, making Antora’s approach a promising solution to decarbonize without risking downtime.
The funding round follows previous capital injections totaling over $230 million, including a $150 million Series B in early 2024 led by Decarbonization Partners, with participation from BlackRock and Temasek. also Antora earned a $14.5 million grant from ARPA-E, the DOE’s innovation arm, signaling strong government backing for their high-risk, high-reward energy tech.
Earlier this year, Antora expanded its manufacturing capacity by doubling its California campus. This expansion supports a milestone project at POET’s ethanol plant in South Dakota, which will deploy over 200 thermal batteries totaling 5 gigawatt-hours of storage set to become the largest thermal energy storage project worldwide.
Beyond ethanol production, Antora targets industries like chemicals, food and beverage manufacturing, and notably the rapidly growing data center market, where energy demands are intensifying.
