The United States is expanding its domestic lithium industry to support electric vehicles, grid-scale energy storage systems, and other clean technology sectors. New research indicates that the challenge may extend beyond locating deposits to securing sufficient water for extraction. The study also notes that climate change, population growth, and industrial expansion are increasing competition for limited water resources.
Lithium demand drivers and concentration of supply
Lithium is used in rechargeable batteries for electric vehicles, grid-scale energy storage systems, consumer electronics, renewable energy infrastructure, and advanced technology applications. The global supply chain remains concentrated, with most lithium mined in countries including Australia and Chile. Processing and refining are substantially concentrated in China.
To reduce dependence on foreign supply chains and strengthen domestic resource security, the United States has encouraged new lithium mines and processing facilities. Researchers caution that water availability could become a limiting factor for planned expansion.
Communications Earth & Environment study on water constraints
The research was published in the scientific journal Communications Earth & Environment. It assessed whether future water supplies in the United States could meet both existing demands and expected growth in lithium mining. The analysis concludes that meeting projected domestic lithium demand would remain difficult even if all proposed mines became operational.
The study also finds that many planned projects could face substantial water shortages as climate conditions become more unpredictable. It examined one active lithium mine in southwestern Nevada and 22 proposed lithium projects across the country. Climate and hydrological modeling were used to evaluate multiple future scenarios.
Scenarios included hotter climate conditions, drier weather patterns, wetter climate projections, moderate environmental scenarios, and changing population and economic trends. Across nearly all scenarios, many western U.S. regions struggled to meet existing water needs, leaving limited capacity for additional industrial demand.
Water use pathways in brine and hard-rock operations
Lithium production can require intensive water use depending on the extraction method. Large volumes of water are needed across mining and processing activities. In lithium brine operations, mineral-rich groundwater is pumped to the surface where evaporation concentrates lithium deposits.
Hard-rock mining uses different processes but also relies heavily on water for ore processing, material washing, dust suppression, equipment cooling, and chemical treatment. Water contamination is another factor that can complicate operations. Mining and processing can introduce substances such as arsenic and other contaminants into wastewater streams.
Treating and restoring contaminated water to environmental standards can require significant energy inputs, additional infrastructure, and substantial financial investment. The study states that much of the water used during lithium production is effectively removed from local water systems as a result of these processes.
Nevada and California highlighted for future shortages
The study identifies severe future water shortages in Nevada and California’s Salton Sea region, which are described as major targets for future lithium development. Both areas are characterized as experiencing chronic water stress. They also face growing competition among agriculture, residential communities, industrial facilities, power generation, and mining operations.
The report indicates that farming and urban consumption are expected to remain the largest users of water. It adds that lithium mining could increase pressure on already strained resources in these regions. Researchers emphasize that many proposed projects aim to operate where water supplies are already stretched.
Climate-driven shifts affecting availability and demand
The study links mining-related constraints to broader climate impacts across large parts of the western United States. It reports that climate change is expected to alter rainfall patterns, increase temperatures, and intensify drought conditions. These changes could reduce future water availability while increasing demand from households, businesses, and agricultural producers.
As water becomes scarcer, competition between industries is expected to intensify. The research describes this as creating a balancing challenge for policymakers seeking to accelerate clean energy deployment while strengthening domestic critical mineral production and protecting regional water resources.
Technology options discussed for reducing water intensity
The researchers argue that technological innovation will be important for expanding the U.S. lithium industry under constrained conditions. Potential solutions listed include more water-efficient extraction technologies, advanced recycling systems, improved water management practices, strategic mine site selection, and enhanced wastewater treatment processes.
The study also points to direct lithium extraction technologies designed to recover lithium with lower water consumption. It notes that many of these methods remain under development but could reduce environmental impacts and improve resource efficiency.
Recycling as part of future supply planning
The report highlights lithium recycling as an increasingly important component of future supply chains. Recovering lithium from used batteries can reduce dependence on newly mined material while lowering water consumption and environmental impacts. It also addresses supply chain risks associated with reliance on new extraction.
As electric vehicle adoption accelerates, recycling infrastructure is described as potentially becoming a source of domestic lithium production. The study states that developing a circular economy for battery materials may be as important as opening new mines.
Implications for critical minerals strategy tied to resource access
The study frames access to critical minerals as only one part of the clean energy transition equation. It emphasizes that access to natural resources required for extraction—especially water
—can be equally important for scaling domestic production. Without improvements in water efficiency, recycling approaches, and resource planning, climate-driven shortages could become a major obstacle to building a secure and self-sufficient lithium supply chain.
