A Houston-based startup, Element3, is transforming the landscape of energy production in the Permian Basin, West Texas, by extracting lithium from wastewater produced during oil drilling. This innovative approach not only addresses the growing demand for lithium, crucial for electric vehicle (EV) batteries, but also offers a sustainable solution by utilizing a by-product traditionally considered waste.
The Permian Basin, a vast expanse known for its oil production, yields approximately 6 million barrels of oil daily. However, it also produces about 26 million barrels of brackish water each day, a by-product of drilling operations. This water, rich in minerals like lithium, has long been overlooked as a potential resource. Element3, founded in 2021, saw an opportunity in this overlooked resource, leveraging research from the U. S. Department of Energy's Oak Ridge National Laboratory to filter and extract lithium from the wastewater.
Element3's CEO, Hood Whitson, describes this initiative as a significant opportunity for re The company's approach not only taps into one of the nation's largest untapped natural resources but also aligns with the broader shift towards clean energy. The startup has raised over $20 million and employs 15 people, according to PitchBook.
Lithium Extraction Process
Element3 has established a 6,000-square-foot commercial extraction facility in Midland, Texas, marking the first new lithium extraction site in the U. S. since the 1960s. The facility employs a proprietary medium and a direct lithium exchange unit to absorb lithium ions from the wastewater. This process yields lithium chloride, which is then processed into lithium hydroxide, essential components for battery production. The facility has the capacity to produce up to 3,000 tons of lithium annually, a significant contribution compared to the 5,000 tons produced by the only existing U. S. lithium mine in Silver Springs, Nevada.
The extraction process developed by Element3 is not only innovative but also environmentally friendly. It generates lower emissions compared to traditional lithium mining methods, both domestically and internationally. This positions Element3 as a leader in sustainable lithium production, contributing to the reduction of carbon footprints associated with battery manufacturing.
Currently, the extracted wastewater is diverted through an extensive network of pipes used by the energy industry for fracking. Element3's facility is strategically located adjacent to these pipelines, allowing for efficient diversion, filtration, and return of the treated water back into the system. This eliminates the need for additional disposal or transportation, further enhancing the sustainability of the process.
Whitson emphasizes the potential of this resource, noting its significance in reducing reliance on imports, particularly from China, which accounted for over $16 billion worth of lithium-ion battery imports to the U. S. in 2024.
Element3's efforts are part of a broader trend in Texas, where the energy sector is diversifying beyond oil and gas. The state has made significant strides in renewable energy, including wind, solar, and geothermal, often utilizing the skilled workforce from the oil and gas industry. Companies like Iofina are also exploring ways to capitalize on wastewater, with a new facility in West Texas focused on iodine production.
Whitson sees this as a pivotal moment for the energy industry, highlighting the potential for growth in the critical materials sector. This shift not only creates new opportunities for high-paying energy jobs but also demonstrates the industry's ability to adapt to evolving energy demands.
As Element3 continues to scale its operations, it stands as a testament to the potential of innovative solutions in addressing both environmental and economic challenges. By turning a waste product into a valuable resource, the company is paving the way for a more sustainable and energy-efficient future.
