Heliogen Secures $108M Funding for Solar Concentration Technology

Heliogen's Concentrated Solar Technology: A Breakthrough in High-Temperature Energy

While the sun provides substantial energy, it typically lacks the intensity needed for processes like steel production. Heliogen is pioneering a novel approach to concentrated solar power, aiming to achieve temperatures previously unattainable. The company has secured over $100 million in funding to test its 1,000-degree Celsius solar furnace at select mining and refining facilities.

The Core of Heliogen's Innovation

Our initial coverage of Heliogen in 2019 highlighted the fundamental principles of their technology, which remain central to their operations. The system employs advanced computer vision to precisely manage an array of mirrors. These mirrors collectively reflect and focus sunlight, generating heat exceeding 1,000°C – a significant leap beyond the capabilities of conventional solar concentrators.

Founder Bill Gross previously described the system as akin to a “death ray,” emphasizing its concentrated energy output. This capability allows for the substitution of fossil fuels in numerous industrial applications requiring high temperatures, such as mining and smelting.

Potential for Cost Reduction and Environmental Benefits

By integrating a Heliogen concentrator, operations can leverage solar energy for a substantial portion of the day, reducing reliance on alternative energy sources during nighttime hours. This transition could potentially reduce fuel costs by as much as 50%, leading to both economic savings and a reduced carbon footprint.

Recent Investment and Expansion

The potential for both financial returns and environmental sustainability has attracted investment from utility companies and a leading mining and steel manufacturer. Heliogen recently completed a $25 million Series A-2 funding round, spearheaded by Prime Movers Lab.

Subsequently, a larger “bridge extension” round of $83 million was secured, with participation from ArcelorMittal, Edison International, Ocgrow Ventures, and A.T. Gekko, among others.

Deployment and Development Plans

These funds will be allocated to both the ongoing refinement of the “Sunlight Refinery” – Heliogen’s term for its technology – and the implementation of on-site installations within active production environments. A company spokesperson confirmed that continuous improvements are being made to enhance efficiency and lower costs.

Pilot Programs and Strategic Partnerships

A pilot project is scheduled for Boron, California, at a Rio Tinto borates mine. Heliogen’s technology will be integrated into the mine’s existing operations, as outlined in a Memorandum of Understanding (MOU) signed in March.

Furthermore, an MOU with ArcelorMittal will explore the integration of Heliogen’s products into several of ArcelorMittal’s steel plants, with planned facilities in the U.S., the Middle East and North Africa (MENA) region, and the Asia Pacific area.

Beyond Mining: Hydrogen Production and Industrial Applications

The technology’s applications extend beyond mining and smelting, offering a pathway to zero-carbon hydrogen production. This advancement is crucial for establishing a viable hydrogen infrastructure for future fuel supplies, as current production methods often depend on fossil fuels.

Numerous other industrial processes could also benefit from access to a free and carbon-neutral source of high-intensity heat.

A Vision for a Post-Carbon Economy

“We are being provided with the resources to undertake more projects that address the most carbon-intensive human activities and advance our objectives of reducing energy costs and emissions for all,” stated Bill Gross in a press release. “We extend our gratitude to all our investors for empowering us to pursue our mission and deliver technology that will enable the world to transition to a post-carbon economy.”
