By 2020, their demonstration plant in El Dorado proved industrial-scale feasibility. In 2024, Equinor acquired 45% of two lithium projects in Arkansas and Texas, with $225 million in US government grants announced in January 2025 for direct lithium extraction. A feasibility study confirmed a production capacity of 22,500 tons of lithium carbonate annually.
