The United States is playing a dangerous game of catch-up in the electric vehicle race, and it’s not because we don't have enough lithium. We have plenty of it buried in the brines of the American South. The problem is we haven't been able to process it without shipping it across the Pacific first.
China currently controls roughly 70 to 75 percent of global lithium chemical conversion capacity. They've spent years keeping margins razor-thin, effectively killing off any Western competition before it can even start. If you want to build a battery in the US, you're almost entirely dependent on a supply chain that runs straight through Beijing.
Energy Exploration Technologies, known simply as EnergyX, wants to rewrite that script from an old US Army munitions site near Texarkana. In March 2026, the Austin-based startup officially commissioned the first integrated direct lithium extraction (DLE) demonstration facility in Texas. CEO Teague Egan isn't hiding his ambition, framing the former military property as the foundation for a future "Battery Mecca."
This isn't just another green energy press release. It's an attempt to solve the exact value chain choke point that makes domestic critical mineral resources functionally stranded.
Breaking the Conversion Bottleneck
Most people think the lithium bottleneck is about mining. It isn't. The real fight is over mid-stream processing. Mining raw lithium ore or pumping up salty brine is just the first step. You can't just throw raw lithium into an EV battery; it has to be converted into high-purity, battery-grade chemicals like lithium carbonate or lithium hydroxide.
Because Western companies lack domestic conversion capacity, they're forced to export raw materials to foreign processing hubs, only to reimport the finished chemicals at a premium. It's a massive vulnerability for both domestic economic independence and national defense readiness.
The new EnergyX Project Lonestar demonstration plant in Hooks, Texas, tackles this head-on by combining extraction and refining under a single roof. The facility is processing brine from the Smackover formation, a geological trend rich in hydrocarbons and lithium that stretches across Texas, Arkansas, and Louisiana.
Right now, the plant is scaled to produce about 250 metric tons of battery-grade lithium carbonate equivalent (LCE) annually. That's a drop in the bucket compared to global demand, but the output isn't the point. The point is proving that the tech works under real-world, industrial conditions.
The Tech Behind the Scale
Traditional lithium extraction from brine relies on massive evaporation ponds. You pump brine into giant fields, let the sun evaporate the water over 12 to 18 months, and then process the sludge left behind. It's incredibly slow, requires massive footprints, and leaves a lot of lithium behind, usually recovering less than 50% of the material.
EnergyX is betting its future on a proprietary suite of technologies called GET-Lit. Instead of waiting on the sun, this process relies on a combination of selective membranes, adsorbents, and solvent extraction techniques.
Sorbents and Membranes
The process uses spherical bead sorbents that act like chemical magnets, pulling lithium molecules directly out of the brine with rapid kinetics. Once the lithium attaches to the sorbent, a simple water wash releases it.
Speed and Efficiency
The entire process takes one to two days rather than nearly two years. EnergyX reports a recovery rate of roughly 90%, which effectively doubles the yield from the same volume of raw brine compared to old-school evaporation methods.
Cost Structure
The startup claims this process will make them the lowest-cost producer in the US, citing operating expenses around $3,850 per metric ton for future commercial phases. Power requirements for the separation process sit below $100 per ton, and fresh water consumption is kept to a minimum.
The Multi-Billion Dollar Scaling Strategy
You can't build a global mining and refining powerhouse on pocket change. EnergyX has already spent roughly $30 million to get the Texarkana demonstration plant off the ground. That early runway came via backing from heavy hitters like GM Ventures, South Korean steel giant POSCO, and Boston-based venture capital firm Eni Next.
But scaling up to full commercial production means Egan will need to raise billions of dollars over the next few years. The strategy to move from a 250-ton demonstration plant to a true commercial footprint relies on a massive land grab in the Smackover region.
Through its acquisition of Daytona Lithium from Pantera Lithium, EnergyX expanded its territory to nearly 50,000 gross acres across Texas and Arkansas. The company estimates this resource holds up to 3.2 million tonnes of lithium in situ, with lithium concentrations hitting a high 520 mg/L.
The blueprint for Project Lonestar maps out two distinct phases:
- Phase I (Targeting 2028): Aiming for 14,250 tons per annum (tpa) of lithium hydroxide production, with an estimated capital expenditure of $22,900 per annual ton.
- Phase II (Targeting 2030): Scaling operations up to 48,500 tpa of high-purity, battery-grade material.
The total projected investment to realize this scale sits around $1.15 billion. Engineering has already progressed into advanced stages with global engineering firm Worley.
The Realities of Challenging the Status Quo
Let's look at this realistically. EnergyX's economic thesis hinges on the assumption that they can undercut or match Chinese conversion costs once you factor in shipping and logistics. But entering the mining and refining sector is notoriously brutal.
The industry is littered with startups that promised revolutionary DLE tech but failed when trying to scale from a controlled laboratory environment to processing millions of gallons of corrosive, hot brine every day. Equipment degrades quickly. Sorbents break down. System efficiencies can drop when handling real-world impurities that don't show up in a lab sample.
Furthermore, commodity markets are incredibly volatile. China has shown a willingness to flood markets to depress prices and squeeze out Western competitors that carry heavier capital debt. EnergyX has the benefit of a $5 million grant from the U.S. Department of Energy to advance its technology, but government grants won't save a commercial project if macro prices stay depressed for too long.
What gives the company a fighting chance is the absolute geographic advantage of East Texas. Proximity to major North American automotive assembly plants and battery gigafactories reduces logistical complexity. If they can consistently hit their 99.9% purity targets at the scale they are projecting, they will find an eager domestic market ready to pay for supply chain security.
If you are tracking the domestic energy transition, keep your eyes on the Smackover formation over the next 24 months. The immediate hurdle for EnergyX isn't the science; it's securing the institutional debt and equity required to transition Project Lonestar from a successful 250-ton demonstration facility into a billion-dollar commercial asset. Watch for upcoming announcements regarding their next major financing rounds and off-take agreements with domestic automakers, as those milestones will dictate whether this Texas facility actually becomes the center of gravity for American battery materials.
