$272M total raised. Commercial-scale thermal battery deployments launching in 2026. DOE-backed cement consortium (1.1M tonne CO2/yr reduction). Heat-as-a-service model.
Antora Energy builds carbon-block thermal batteries that store cheap renewable electricity as ultra-high-temperature heat (up to 1,500°C), then deliver industrial process heat on demand — displacing natural gas in hard-to-abate sectors like cement, steel, and chemicals. The company has raised $272 million in total funding and is launching its first commercial-scale deployments in 2026, integrated into a DOE-backed cement industry consortium targeting 1.1 million tonnes of CO2 reduction per year.
$475M committed for two Louisiana DAC facilities (17K + 100K tonne/yr). First commercial-scale DAC going operational in 2026. DOE Project Cypress hub partner.
Heirloom Carbon is one of the only direct air capture (DAC) companies to cross from pilot scale to actual commercial operation in 2026, with its first facility in Shreveport, Louisiana going operational this year. The company has secured $475 million in committed investment for two Louisiana plants: a 17,000-tonne-per-year facility now operational and a 100,000-tonne-per-year facility under development — representing the largest DAC buildout in North America.
