Replacing fuels with sunlight

Heliogen is a clean energy company focused on eliminating the need for fossil fuels.

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

Solving the world’s CO2 problem

Heliogen’s patented technology powers historically dirty processes with clean, renewable sunlight and is also capable of transforming sunlight into fuels like hydrogen and syngas.

Our Solutions


HelioMax features a breakthrough closed-loop control system that consistently delivers high optical performance and saves months of time in calibration. The HelioMax boasts higher concentration and more flux per dollar than any other heliostat system and is available for both electricity generation and process heat applications.


Our carbon-free, ultra-high temperature (up to 1500ºC) heat can be used by customers to replace their use of harmful fossil fuels. Historically dirty processes like calcining, reforming, ore roasting, and sintering, which are used in industries such as cement, refining, and mining can now be made green with HelioHeat.


Clean, renewable fuels created by our carbon-free, ultra-high temperature heat can be used in applications as diverse as transportation, heavy equipment, and household heating. To start, we’re focused on the production of green hydrogen – the fundamental clean fuel.

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 HelioMax 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 thermo-chemically splitting water to create 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.
