Rio Tinto leveraging solar to electric power California mine | Technology

Rio Tinto and renewable power know-how firm Heliogen have introduced an agreement to explore the deployment of Heliogen’s breakthrough photo voltaic technological know-how at Rio Tinto’s borates mine in Boron, California.

Less than a Memorandum of Comprehension, Heliogen will deploy its proprietary, artificial intelligence (AI)-run technology at the Boron procedure, the place it will use heat from the sunshine to produce and keep carbon-free electricity to power the mine’s industrial processes. The two providers will start out specific preparing and securing federal government permits for the undertaking, with the aim of starting operations from 2022. 

The organizations will also use the Boron set up to start out discovering the opportunity for deployments of Heliogen’s know-how at Rio Tinto’s other functions about the planet to provide course of action heat, which accounted for 14% of Scope 1 & 2 emissions from the Group’s managed operations in 2020.

Heliogen’s superior-temperature photo voltaic technological innovation is made to charge-correctly swap fossil fuels with sunlight for a vary of industrial procedures, such as these used in mining. At Rio Tinto’s Boron mine, the company’s proprietary know-how will use AI to management a network of mirrors that concentrate sunlight to capture power utilized to make steam. Heliogen’s system will also keep the captured strength in the variety of heat, letting it to electricity night time time functions and furnishing the same uninterrupted electrical power stream offered by legacy fuels.

The Boron procedure mines and refines borates into solutions ranging from fertilizers to design resources and is producing lithium carbonate from a demonstration plant. The web site at present generates steam applying a natural gas cogeneration plant and normal fuel fired boilers. 

Heliogen’s set up will complement these electrical power sources by producing up to 35,000 lbs for every hour of steam to ability operations, with the prospective to reduce carbon emissions at the Boron internet site by all around 7% – equivalent to taking additional than 5,000 cars off the highway. Rio Tinto will also be assessing the potential for much larger scale use of the Heliogen technology at Boron to lower the site’s carbon footprint by up to 24%.

How it performs


Heliogen’s mission of slashing world-wide carbon emissions by replacing fossil fuels with daylight, as very well as its concentration on industrial sectors, created them an excellent spouse for Rio Tinto, which is dedicated to decarbonizing its world operations.

Rio Tinto Chief Government Jakob Stausholm claimed: “This partnership with Heliogen has the possible to considerably lessen our emissions at Boron by making use of this groundbreaking photo voltaic know-how, and we look forward to discovering opportunities across our international portfolio.

“Addressing local climate adjust proficiently will have to have firms, governments and culture to do the job with each other by way of partnerships like this one particular, to check out progressive new remedies throughout the complete benefit chain. Our operate with Heliogen is component of Rio Tinto’s determination to shell out around $1 billion on emissions reduction initiatives via to 2025 and our commitment to do the job with world-major know-how suppliers to achieve this goal.”

Heliogen CEO and Founder Invoice Gross additional: “Since its founding, Heliogen has been laser-concentrated on decarbonizing industrial sectors, which include mining. As a final result, this agreement with Rio Tinto is extremely gratifying. We’re happy to locate a companion committed to chopping its contributions to local weather alter. We’re also delighted that Rio Tinto is exploring our technology to participate in an crucial position in serving to attain its sustainability plans although drastically lessening its electricity prices. 

“More broadly, we’re thrilled to acquire this critical move as we go after Heliogen’s aim of keeping away from more than 1 gigaton of CO2 emissions – 5% of the world’s once-a-year full – from the worldwide financial system by turning daylight into an industrial power resource.”
