Replacing fossil fuels

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 is developing the technology to do just that.

On-Demand Renewable Energy™

Heliogen is developing a concentrated solar solution utilizing unique advanced computer vision software to precisely align an array of mirrors, reflecting sunlight to a target on the top of a tower. Powered by artificial intelligence (AI), our modular system aims to deliver low-cost renewable energy in the form of heat, power, or hydrogen fuel – whenever it’s needed, however it’s needed.

Our Solutions


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


Power 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’s technology will cost-effectively deliver near-24/7 carbon-free energy in the form of heat, power, or green hydrogen fuel at scale.

How it Works

The advanced computer vision software unique to Heliogen’s breakthrough technology precisely aligns an array of mirrors to reflect sunlight to a target on the top of a Sunlight Refinery™ tower, delivering high-temperature, carbon-free thermal energy.

The baseline system will provide industrial-grade heat capable of replacing fossil fuels in industrial processes including the production of cement, steel, and petrochemicals.

Heliogen’s technology will also enable power generation through the addition of a supercritical CO2 turbine, and green hydrogen fuel production in combination with an electrolyzer.

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.
