Turning North Dakota Brine Into Battery Power

Lithium Harvest targets two North Dakota plants to extract battery-grade lithium from Bakken oilfield wastewater by late 2027

17 Mar 2026

Lithium Harvest has reached an agreement to construct two extraction facilities in the Bakken formation of North Dakota. The project aims to recover battery-grade lithium from wastewater generated during oil production. By integrating these plants into existing water management hubs, the company intends to establish a domestic source of critical minerals by late 2027.

The initiative relies on a partnership with a midstream water management firm to co-locate operations at sites already handling oilfield fluids. This logistical arrangement removes the need for long-distance trucking and reduces overall carbon emissions. The two facilities are designed to process over 100,000 barrels of produced water daily, yielding an estimated 3,000 tonnes of lithium carbonate per year.

Company data indicates that capital expenditure for the North Dakota sites will remain below $60m. At full capacity, the operator projects gross margins between 60% and 77%. The business model utilizes a patented adsorption process specifically calibrated for the chemical profile of Bakken brine. Under a design-build-own-operate structure, the midstream partner receives a royalty on the feedstock, providing a continuous stake in the mineral output.

The development reflects a broader shift in the regional economy. North Dakota state officials have identified at least four separate lithium projects currently under review. This includes Wellspring Hydro, which secured a $500,000 grant from the North Dakota Industrial Commission in late 2025. These private ventures align with federal efforts to reduce reliance on mineral imports, as the US Department of the Interior continues to classify lithium as a priority for national resource security.

For the shale industry, the extraction of minerals transforms oilfield wastewater from a waste disposal challenge into a potential revenue source. Historically, this water was managed through deep-well injection, which incurred significant costs for energy producers. The introduction of mineral recovery technology alters the fiscal outlook for water management in the Williston Basin.

While the technical feasibility of direct lithium extraction is established, the long-term commercial success of these plants depends on sustained demand from the electric vehicle battery sector. Regulators and investors now await the results of initial testing to determine if the Bakken can compete with lower-cost brine operations in South America.
