About

Heliogen is an energy technology company that uses AI-powered concentrated solar technology combined with long-duration thermal energy storage to deliver 24/7 carbon-free heat, steam, and electricity for industrial, utility, and data center operations. The company's heliostat systems use computer vision and machine learning to precisely track and concentrate sunlight onto a central receiver tower, generating temperatures up to 1,000°C — sufficient to replace fossil fuels in energy-intensive industrial processes such as cement manufacturing, mining, food and beverage processing, and oil and gas. Heliogen was founded in 2013 by serial entrepreneur Bill Gross out of Idealab, with backing from Bill Gates and other investors. The company went public via SPAC merger in 2021 and operates an automated manufacturing facility in Long Beach, California designed for high-volume production of its modular solar systems.

Summary

Heliogen is a Climate Tech company based in Pasadena, United States, founded in 2013. It has raised $259.0M in total across 10 rounds, most recently a $18.0M Series B round in Nov 2024. Investors include Breakthrough Energy Ventures, Prime Movers Lab and ArcelorMittal.
