Bill Gatesis backing a new venture which aims to turn sunlight into a source of heat exceeding 1, 000 C 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.

The technology could even reach temperatures of 1, 500 C to split hydrogen particles from water to create a fossil-free gas towarm homes, fuel cars and

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.

Gross said creating low-cost, ultra-high-temperature process heat gives the company an opportunity to make meaningful contributions to solving the climate crisis.

The technology can generate temperatures high enough to manufacture cement without creating greenhouse gases.

Cement is theworld’s third largest source of emissions behind oil and coal, and its production is expected to boom due to urbanization in developing countries and economic growth.

If allowed to continue unchecked, cement production would pose a major threat to the targets set by the Paris agreement, which aims to limit rising temperatures to 1.5C above pre-industrial levels.

Heliogen has the backing of private equity investors and entrepreneurs who believe its technology could help the most polluting industries to cut their carbon emissions.

Early investors in Heliogen include Gates, the venture capital firm Neotribe and the billionaire Patrick Soon-Shiong’s Nant Capital.

Gates said he was pleased to be an initial backer of a “promising development in the quest to one day replace fossil fuel”.

“Today, industrial processes like those used to make cement, steel, and other materials are responsible for more than a fifth of all emissions,” he added. “These materials are everywhere in our lives but we don’t have any proven breakthroughs that will give us affordable, zero-carbon versions of them. If we’re going to get to zero carbon emissions overall, we have a lot of inventing to do. ”
