About Heliogen, Inc.

Heliogen, Inc. is a U.S.-based energy technology company that has historically been listed on the NYSE under the ticker HLGN and later traded on the OTCQX market as the company pursued restructuring and strategic alternatives. Headquartered in Pasadena, California, United States, Heliogen was created at Idealab, the technology incubator founded by Bill Gross, and has long focused on next-generation concentrated solar power. Its business model is centered on developing and commercializing AI-enabled solar thermal solutions designed to deliver dispatchable energy rather than only intermittent power. Heliogen’s core platform uses heliostat fields, solar receivers, thermal energy storage, and heat engines or related conversion systems. The goal is to produce high-temperature industrial heat, around-the-clock process steam, clean electricity, and, in some configurations, green hydrogen. This makes the company distinct from conventional photovoltaic developers because Heliogen emphasizes stored thermal energy that can be released on demand for industrial applications. In prior filings and disclosures, the company referenced product concepts such as HelioHeat, HelioPower, and HelioFuel, underscoring its focus on decarbonizing heavy industry and other heat-intensive use cases. From a competitive standpoint, Heliogen has operated as a niche technology developer in a challenging segment where differentiation depends on thermal performance, cost reduction, and the ability to move from demonstration projects to commercial-scale deployment. Its geographic footprint has remained primarily U.S.-centric, although its addressable market is global, especially in sun-rich regions and industrial markets seeking firm clean energy solutions. The company’s value proposition has targeted industrial customers, utilities, and, more recently, power-hungry data center demand through cleaner firm energy offerings. Recent developments are material. In January 2025, Heliogen announced the conclusion of its Capella demonstration project, which it described as an important milestone for its Generation 3 CSP technology. In May 2025, the company entered into a definitive merger agreement with Zeo Energy in an all-stock transaction intended to create a broader clean energy platform. For investors, Heliogen represents a high-risk, highly thematic clean-energy technology story tied to industrial decarbonization, renewable heat, and energy storage innovation.
