Replacing fuels with sunlight

Heliogen is a renewable energy technology company unlocking the power of sunlight to replace fossil fuels.

Cost-effectively replacing fossil fuels solves the world’s CO2 problem and Heliogen develops the technology to do just that.

Unlocking the Power of Sunlight

Heliogen has developed a concentrated solar solution utilizing unique advanced computer vision software to precisely align an array of mirrors, reflecting sunlight to a single target with unprecedented accuracy. Heliogen’s technology concentrates, stores, and refines sunlight into cost-effective energy on demand. This near 24/7, renewable energy is available as heat, electricity, or fuel in modular deployments.

Our Solutions


Carbon-free, ultra-high temperature heat to power heavy industrial processes including the making of cement, steel, and petrochemicals.


Electricity made from sunlight using supercritical CO2 turbines to power industrial facilities, data centers, and mining operations.


Clean fuels like green hydrogen that can be used to power industry and as fuel in transportation, heavy equipment, and household heating.

Heliogen has created the world’s first technology that can commercially replace fuels with carbon-free, ultra-high temperature heat from the sun.

How it Works

The breakthrough in Heliogen’s technology starts with our patented closed-loop control system that makes our field of mirrors act as a multi-acre magnifying glass to concentrate sunlight. The system is an industry first and a critical step in harnessing the power of the sun. Our ability to concentrate and capture sunlight allows us to create carbon-free, ultra-high temperature heat (HelioHeat) commercially for the first time.

From there, HelioHeat can be used by customers as an alternative to burning fossil fuels, which would significantly reduce energy costs, dramatically lower carbon emissions, and help make great strides in reaching and exceeding corporate sustainability goals.

The Heliogen technology is also capable of creating 100% green hydrogen, which we are working to develop as our first HelioFuel.

Our technology at scale is, for the first time, efficient enough to make our ultra-high temperature heat and renewable fuels competitive with fossil fuels. This is a breakthrough for the industry and a major step toward solving climate change.

Bill Gates

Gates Ventures

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.
