Antora Energy
Antora Energy is a U.S.-based energy technology company founded in 2017, focused on decarbonizing industrial heat and power through innovative thermal battery technology. The company aims to combat climate change by providing affordable, clean energy solutions for heavy industries, utilizing renewable electricity primarily from wind and solar sources. The core of Antora's technology is a thermal battery system that stores energy as heat in solid carbon blocks, which can reach temperatures of up to 1,800°C. This heat can be used directly for industrial processes or converted back into electricity using a high-efficiency thermophotovoltaic device. Antora's thermal battery modules are designed for rapid deployment and scalability, making them suitable for various sectors, including chemicals, food and beverage, steel, and mining. With a gigafactory in San Jose, California, Antora Energy is positioned to meet the growing demand for zero-emission energy solutions. The company has raised over $230 million in funding to support its expansion and aims to deploy terawatt-hours of thermal batteries globally in the coming years, contributing to the transition to a zero-carbon economy.
