Heliogen Achieves Breakthrough Temperature in Solar Thermal Application

Heliogen has announced that for the first time commercially, it has concentrated solar thermal energy to exceed temperatures greater than 1,000 degrees Celsius.

Clean energy company, Heliogen has announced its launch and that it has – for the first time commercially – concentrated solar thermal energy to exceed temperatures greater than 1,000 degrees Celsius.

The firm that is working on transforming sunlight to create and replace fuels, said that at that temperature, it can replace the use of fossil fuels in critical industrial processes, including the production of cement, steel, and petrochemicals, dramatically reducing greenhouse gas emissions from these activities. This singular scientific achievement was accomplished at Heliogen’s commercial facility in Lancaster, California.

Heliogen’s mission is to create the world’s first technology that can commercially replace fossil fuels with carbon-free, ultra-high temperature heat from the sun and to transform sunlight into fuels at scale – taking a major step towards solving climate change. Its heat technology represents a key technical breakthrough for concentrated solar thermal. Previous commercial concentrating solar thermal systems have been designed to reach temperatures of up to only 565 degrees Celsius – useful for power generation, but insufficient for many industrial processes. Many of these processes require much higher temperatures, which have traditionally been reached through the burning of fossil fuels.

The potential impact of the firms’ patented technology is massive. With temperatures from its concentrating solar thermal technology exceeding 1,000 degrees Celsius, Heliogen will be able to replace the fuel that generates greenhouse gas emissions from industrial processes with solar energy for the first time. For instance, cement production – one of the industrial processes well suited to Heliogen’s technology – alone accounts for more than 7 percent of global CO2 emissions.

In addition to industrial process heat, Heliogen’s technology roadmap calls for temperatures up to 1,500 degrees Celsius. At that temperature, Heliogen can perform CO2-splitting and water-splitting to make 100 percent fossil-free fuels such as hydrogen or syngas.

The company is able to achieve these breakthrough temperatures as a result of its technology that uniquely uses advanced computer vision software to hyper-accurately align a large array of mirrors to reflect sunlight to a single target.

“The world has a limited window to dramatically reduce greenhouse gas emissions,” said Bill Gross, CEO and Founder, Heliogen, and Founder and Chairman, Idealab. “We’ve made great strides in deploying clean energy in our electricity system. But electricity accounts for less than a quarter of global energy demand. Heliogen represents a technological leap forward in addressing the other 75 percent of energy demand: the use of fossil fuels for industrial processes and transportation. With low-cost, ultra-high temperature process heat, we have an opportunity to make meaningful contributions to solving the climate crisis.”
