Texas-Based EnergyX’s Project Lonestar™ Signals a Turning Point for U.S. Lithium Supply

Energy Exploration Technologies, Inc. (EnergyX), led by CEO Teague Egan, has moved the United States closer to building a reliable domestic lithium supply chain. The company recently commissioned its Project Lonestar™ lithium demonstration facility in Texas, marking a key milestone in scaling direct lithium extraction (DLE) technologies.

This development comes at a time when lithium demand is rising sharply due to electric vehicles and energy storage systems. At the same time, the U.S. remains heavily dependent on foreign processing, particularly from China.

• According to the US import data and Lithium import data of the USA, the total value of US lithium imports reached $432.36 million in 2024, a 9% decline from the previous year.
• The total value of US lithium imports (cells & batteries) accounted for $205.29 million in the first 6 months of 2025.

Against this backdrop, EnergyX’s progress offers both technological validation and strategic value.

From Concept to Reality: How Project Lonestar™ Works

Project Lonestar™ is EnergyX’s first major lithium project in the United States and its second globally. The demonstration plant, located in the Smackover region spanning Texas and Arkansas, is now operational and uses industrial-grade systems rather than small pilot equipment.

• The facility produces around 250 metric tons per year of lithium carbonate equivalent (LCE).

While this output is modest compared to global supply, its importance lies in proving that EnergyX’s proprietary GET-Lit™ technology can efficiently extract lithium from brine. The plant processes locally sourced Smackover brine, a resource that has historically been underutilized despite its lithium potential.

Unlike traditional lithium production, which often relies on hard-rock mining or evaporation ponds, DLE technology directly extracts lithium from brine using advanced filtration and chemical processes. This reduces production time and may lower environmental impact.

• More importantly, the Lonestar™ plant can supply 5 to 25 tons of battery-grade lithium samples to customers.

This allows battery manufacturers to test and validate the material before committing to large-scale supply agreements.

Scaling Up: From Demonstration to Commercial Production

The demonstration plant is only the first phase of a much larger plan. EnergyX aims to scale Project Lonestar™ into a full commercial operation capable of producing 50,000 tonnes of LCE annually across two phases.

• The first phase alone targets 12,500 tonnes per year, which would already place it among the more significant lithium producers in the U.S.
• Significantly, the company has invested approximately $30 million in the demonstration facility, supported in part by a $5 million grant from the U.S. Department of Energy.
• For the full-scale project, EnergyX estimates total capital expenditure at around $1.05 billion.

Cost metrics suggest strong economic potential. The company estimates capital costs at roughly $21,000 per tonne of capacity and operating costs near $3,750 per tonne. If these figures hold at scale, the project could compete effectively with global lithium producers, particularly in a market where cost efficiency is becoming increasingly important.

Teague Egan, Founder & CEO of EnergyX, said,

“Bringing the biggest integrated DLE lithium demonstration plant online in the United States is a foundational milestone for EnergyX and for U.S. domestic lithium production in general. This facility not only validates the performance of our technology on an industrial scale under real-world conditions, but also establishes EnergyX as the lowest cost producer in the U.S. Ultimately this benefits all our customers who need large volumes of lithium for EV and ESS applications, as well as any lithium resource owners looking to implement best-in-class DLE technology whom we are happy to license to.”

Breaking the Bottleneck: Why U.S. Refining Matters

One of the biggest challenges facing the U.S. lithium sector is not resource availability but refining capacity. While lithium deposits exist across the country, most battery-grade lithium chemicals are processed overseas.

China dominates this segment, controlling roughly 70 to 75 percent of global lithium chemical conversion capacity. This concentration creates a structural dependency. Even when lithium is mined in the U.S. or allied countries, it is often shipped abroad for processing before returning as battery materials.

Project Lonestar™ directly addresses this gap. By integrating extraction and refining into a single domestic operation, EnergyX is working to build a complete “brine-to-battery” value chain within the United States. This approach could reduce reliance on foreign processing and improve supply chain resilience.

U.S. Senator Ted Cruz highlighted the project’s importance, noting that domestic lithium production supports both energy security and defense readiness, particularly for applications in advanced battery systems.

The Current Landscape: Limited Supply, Big Ambitions

Investment is flowing into regions such as Nevada, North Carolina, and Arkansas. If even a portion of these reserves is converted into production, the U.S. could significantly reduce its reliance on imported lithium.

Active Resources and Future Potential

At present, U.S. lithium production remains relatively small. The only active large-scale operation is the Silver Peak Mine in Nevada, which produces between 5,000 and 10,000 tonnes of LCE annually, depending on market conditions.

However, several projects are in development that could significantly expand capacity. The Thacker Pass project, for example, is expected to produce around 40,000 tonnes per year in its first phase once operational later in the decade.

In addition, brine-based developments in the Smackover region aim to produce tens of thousands of tonnes annually, with long-term plans exceeding 100,000 tonnes across multiple sites.

These projects indicate a shift from a niche domestic industry to a more substantial production base. Still, timelines remain uncertain due to regulatory and financial challenges.

Demand Surge: Batteries Drive the Lithium Boom

The urgency to expand lithium production is driven by rapid growth in battery demand. Electric vehicles, renewable energy storage, and grid modernization are all increasing lithium consumption.

According to S&P Global, U.S. lithium demand is expected to grow at an average rate of 40 percent annually between 2024 and 2029. Canada is projected to see even faster growth, albeit from a smaller base, with demand rising by around 74 percent per year over the same period.

Globally, battery capacity is forecast to approach 4 terawatt-hours by 2030. This expansion highlights lithium’s central role in the clean energy transition. Without sufficient supply, battery production—and by extension, EV adoption—could face constraints.

Why Progress Takes Time

Turning lithium reserves into operational mines and processing facilities is not straightforward. Projects often face long permitting timelines, environmental scrutiny, and legal challenges. Financing can also be difficult, especially in a volatile commodity market.

Local opposition can further complicate development, particularly in areas with high environmental concerns. These factors can delay projects by several years, slowing the pace of expansion.

To address these barriers, the U.S. government is increasing its involvement through funding, policy support, and efforts to streamline permitting. The Department of Energy’s backing of EnergyX reflects a broader strategy to accelerate domestic critical mineral development.

Conclusion: A Strategic Shift in Motion

Project Lonestar™ represents a meaningful step toward reshaping the U.S. lithium landscape. By proving the viability of direct lithium extraction at an industrial scale, EnergyX has laid the groundwork for larger, commercially viable operations.

The project also aligns with national priorities around energy security, supply chain resilience, and clean energy transition. While challenges remain, the combination of technological innovation, government support, and rising demand creates a strong foundation for growth.

As the world moves toward electrification, lithium will remain at the center of the transition. Projects like Lonestar™ show that the United States is beginning to close the gap between resource potential and real-world production—one facility at a time.
