Equinor makes big investment into lithium projects in Arkansas, East Texas

eyes on LI

A Norwegian international energy company has entered into a deal to take a 45-percent share in two lithium project companies in Southwest Arkansas and East Texas.

Equinor, which has its U.S. headquarters in Houston, has reached an agreement with Vancouver, Canada-based Standard Lithium Ltd. to make the acquisition. Standard Lithium retaining operatorship, while Equinor will support through its core competencies, like subsurface and project execution capabilities.

“Sustainably produced lithium can be an enabler in the energy transition, and we believe it can become an attractive business. This investment is an option with limited upfront financial commitment. We can utilise core technologies from oil and gas in a complementary partnership to mature these projects towards a possible final investment decision,” says Morten Halleraker, senior vice president for New Business and Investments in Technology, Digital and Innovation at Equinor, in a news release.

Standard Lithium retains the other 55 percent of the projects. Per the deal, will pay $30 million in past costs net to the acquired interest. The company also agreed to carry Standard Lithium's capex of $33 million "to progress the assets towards a possible final investment decision," per the release. Additionally, Equinor will make milestone payments of up to $70 million in aggregate to Standard Lithium should a final investment decision be taken.

Lithium is regarded as important to the energy transition due to its use in battery storage, including in electric vehicles. Direct Lithium Extraction, or DLE, produces the mineral from subsurface reservoirs. New technologies have the potential to improve this production method while lowering the environmental footprint.

Earlier this month, Houston-based International Battery Metals, whose technology offers an eco-friendly way to extract lithium compounds from brine, announced that it's installing what it’s billing as the world’s first commercial modular direct-lithium extraction plant located at US Magnesium’s operations outside Salt Lake City. The plant is expected to go online later this year.
