A solar energy tech company founded by serial entrepreneur and inventor Bill Gross — and backed by investors including Microsoft co-founder Bill Gates — says it has developed a way to create concentrated solar energy at temperatures hot enough to replace fossil fuels in industrial processes that contribute significantly to global carbon emissions.
It works by using cutting-edge computer vision technology to align a large array of mirrors to reflect sunlight to a precise target. The process creates immense heat, exceeding 1,000 degrees Celsius (1,832 Fahrenheit), that can replace traditional fuels such as coal, gas and oil in the production of materials such as cement, steel and petrochemicals.
The Los Angeles-based company, Heliogen, said this morning that it achieved the high-temperature milestone at its commercial facility in Lancaster, Calif.
It described the innovation as a “major step towards solving climate change” that could dramatically reduce greenhouse gas emissions from industrial processes. Such processes are thought to account for one-fifth of the world’s carbon emissions.
