“Heliogen is a startup that wants to “replace fuels with sunlight.” And the Bill Gates-backed solar startup, which has flown under the radar until today, has made a major green-energy breakthrough for heavy industry. Heliogen “has created the world’s first technology that can commercially replace fuels with carbon-free, ultra-high temperature heat from the sun.”
Heavy industry such as steel, cement, and petrochemicals are major polluters because they need extremely high heat to manufacture their products. According to the EPA, heavy industry creates more than one-fifth of global emissions.
Heliogen, which was created at the technology incubator Idealab, has now figured out how to concentrate so much sunlight that it generates extreme heat above 1,000 degrees Celsius. That way, heavy industry can replace fossil fuels with solar, thus reducing greenhouse gas emissions…”
