Industrial-Strength Ultra-High Temperature Solar

Posted: 12.18.2019 no comments


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 recently, 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.


Heliogen is able to achieve these breakthrough temperatures by using advanced computer vision software to hyper-accurately align a large array of mirrors to reflect sunlight to a single target.


Bill Gross, the CEO and founder of Heliogen (and the founder and chairman of Idealab) said:

“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% 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.”


Bill Gates said of Heliogen’s breakthrough:

“Today, industrial processes like those used to make cement, steel, and other materials are responsible for more than a fifth of all emissions. 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. I’m pleased to have been an early backer of Bill Gross’s novel solar concentration technology. Its capacity to achieve the high temperatures required for these processes is a promising development in the quest to one day replace fossil fuel.”


Heliogen will bank its energy with storage systems for cloudy days so that industrial production isn’t interrupted. The company wants to grow quickly and then go public. Its biggest selling point to potential industrial customers, if saving the world from the climate crisis isn’t enough? Sunlight is free.
