Get a Second Revenue Line - Lithium Extraction from Geothermal Brines
Generate revenue from clean energy and critical minerals - from the same brine, on the same site.
Your geothermal brine isn’t just hot water. It can carry high-value lithium - and it’s already flowing through your system every day.
That’s the opportunity: turn a single-revenue geothermal asset into dual revenue.
Why now?
Lithium demand is set to grow 4x by 2035, but traditional mining can’t keep up. It’s slow, capital-intensive, and out of sync with what the battery market needs.
What changes with Lithium Harvest
We turn your geothermal brine into a second revenue stream without changing how you run your plant. Our modular direct lithium extraction solution integrates with your existing brine loop, delivered under a DBOO model - we design, build, own, and operate the lithium plant.
No megaproject. No operational headache. Just high-margin lithium revenue from the same source - and one of the fastest, cleanest ways to increase your asset value.

We make geothermal lithium simple. You keep running your plant - we design, build, own, and operate the lithium system that unlocks a second revenue stream from the same brine.
From Hot Brine to a Dual Revenue Line
A closed-loop process integrated with your brine loop - designed for high recovery and no disruption.
Turn your geothermal plant into a hybrid revenue engine. You keep producing clean energy. We unlock lithium revenue from the same brine, delivered under a DBOO model in which we design, build, own, and operate the lithium plant.
We’ve worked with industrial water and complex brines for over 20 years. Our approach is built on commercially proven fundamentals and engineered for real geothermal operations - technically sound, commercially compelling, and low-hassle for operators.
Our solution combines mature adsorption-based Direct Lithium Extraction (DLE) with advanced water treatment and deep industrial water expertise. That’s what lets us perform on geothermal brines with real-world variability - changing chemistry, scaling risk, temperature swings, and operational constraints - not idealized lab samples.
What makes our approach different?
- High lithium recovery on real geothermal brines: Delivering >95% lithium recovery with a process engineered for uptime and stable operations.
- Adaptable to brine variability: Designed to handle impurities, fluctuations, and site-specific constraints without constant operator intervention.
- Modular and scalable by design: Start with one train, then expand with additional modules as your plant and economics grow.
You stay focused on energy generation - we handle lithium extraction end-to-end.
Low Risk, High Reward
A turnkey, co-located solution engineered for real geothermal operations - and structured to align incentives.
Adding lithium shouldn’t feel like taking on a second business. That’s why we deliver geothermal lithium extraction as an integrated, fully operated add-on to your existing plant - with no need for downtime, steep learning curves, or building a new internal team.
You keep producing energy. We handle the rest.
-
Turnkey, end-to-end delivery
One partner. Every step. Zero hassle.
We handle the full project lifecycle - from validation and design to construction, commissioning, and day-to-day operations. You get a second revenue stream without adding operational burden.
Focus on your core business. We’ll handle the lithium.
-
Strategic co-location with hassle-free integration
Designed to fit your operations, not disrupt them.
We co-locate the lithium plant alongside your geothermal facility and integrate with your existing brine loop and reinjection strategy. Lithium becomes a value add - not a headache.
With a compact, modular design, you get (illustrative):
- Fast deployment - start-up in as little as 12–18 months from FID
- Minimal footprint - a 3,200 m³/day facility can fit in 1.4 acres
- Operational flexibility - lithium extraction can pause or bypass when needed, while core operations keep running.
-
Future-proof by design
Brines vary. Markets change. Plants scale. Our modular platform lets you start at the right size and expand over time, while the process is engineered to manage real-world variability and maintain stable performance.
It’s built to adapt to a wide range of geothermal brine chemistries, including common interfering ions - backed by commercially validated fundamentals that support high lithium recovery and competitive economics from day one.
As the project evolves, the same platform can support a pathway to additional minerals where it makes sense.
Rethinking Critical Mineral Supply - Without the Mining Footprint
Geothermal can deliver clean energy and critical minerals from the same source - with a far smaller footprint than traditional lithium production.
Renewables can’t scale without critical minerals. And critical minerals can’t stay on a high-impact production path if the goal is a cleaner energy system end-to-end.
That’s why geothermal is uniquely positioned. Energy and lithium-rich brine are already co-located on the same site. With the right extraction partner, you can produce clean power and battery-grade lithium from the same source - in a closed loop - with far lower land use, freshwater demand, and emissions than conventional lithium supply.
Lithium Harvest makes it real now by adding modular lithium extraction under a DBOO model, integrated with your existing brine loop. No pits. No ponds. No megaproject. Just a cleaner, more cost-effective, and faster route to lithium - giving your project a clear advantage in the lithium market.
Different ways to produce lithium - very different outcomes.
