Heliogen uses mirrors to concentrate solar energy that can power heavy industry
Bill Gates is backing a new venture which aims to turn sunlight into a source of heat exceeding 1,000C that could help replace fossil fuels.
The world’s richest man is joining investors behind Heliogen, the first company to concentrate sunlight to reach temperatures that are high enough to power heavy industry without carbon emissions.
Bill Gross, the chief executive and founder of California-based Heliogen, said the company represents a technological leap forward in tackling the emissions from industry and transport that make up 75% of the world’s carbon footprint.
The company uses software to align a large array of mirrors to reflect sunlight to a target, creating a source of heat almost three times as intense as previous commercial solar systems.
The technology can generate temperatures high enough to manufacture cement without fossil fuels.
Gross said creating low-cost, ultra-high-temperature process heat gives the company an opportunity to make meaningful contributions to solving the climate crisis.
