Why Modular Lithium Extraction Systems Are Ideal for Geothermal Plants
A smarter, scalable approach to unlocking dual revenue from geothermal brine - without the operational burden.
From One Revenue Stream to Two - Without Doubling the Headache
Imagine this: Your geothermal plant is already up and running, delivering clean energy around the clock. Now, what if you could add a second, high-value product - battery-grade lithium - without having to build a massive new facility, hire a new team, or become a chemical plant operator?
That is the power of modular lithium extraction systems.
With lithium demand expected to rise 6.5x by 2034, the market is hungry - and geothermal brines are an untapped goldmine. Modular extraction facilities offer geothermal energy companies a way to break into this booming sector without losing focus on their core business. These systems are pre-engineered, self-contained, and scalable - designed to match your existing brine flow and grow alongside your energy production.
Yes, you still add a facility - but it is modular, compact, and handled by experts. You do not need to retrain your team or run a complex new operation. The system is installed, managed, and optimized by lithium extraction specialists, enabling you to continue delivering clean energy while enjoying a second revenue stream.
This is not just a technical solution – it is a business model upgrade. One that helps you monetize your brine, boost ROI, and play a central role in building a domestic, low-carbon lithium supply chain.
Let us take a closer look.
The Modular Approach Explained
Modular does not mean you are getting a container. At Lithium Harvest, it means purpose-built, scalable facilities - installed on-site and fully integrated with your geothermal operation.
Our modular lithium extraction and refining facilities are designed to match the pace of your power production. As your geothermal plant expands, your lithium recovery system scales with it - without requiring new land acquisitions, complex retrofitting, or changes to your core business model. In fact, a 3,200 m³/day system only requires about 1.4 acres, drastically reducing footprint, piping needs, and permitting complexity.
With a modular approach, you are not just adding equipment – you are unlocking a flexible, future-proof platform that turns geothermal brines into a new line of business without stretching your team or your balance sheet.
Here is how our modular approach works:
-
Built On-Site, Tailored to You
Each facility is engineered specifically for the chemistry of your geothermal brine and constructed directly on-site, co-located with your power plant to streamline operations and maximize synergy.
-
Design-Build-Own-Operate (DBOO)
You do not need to operate the facility. We take care of everything - from design to daily operation - so you can stay focused on clean energy while unlocking new revenue from your brine.
-
Fast Commissioning
While traditional lithium facilities can take 5–15 years to develop, our modular solution is typically up and running within 12–18 months, thanks to our modular design and streamlined workflows.
-
Scalable Architecture
Whether you are ramping up production or managing variable brine flows, the facility adapts with you. We grow with your needs - no overbuilding, no underperformance.
-
Automated & Low-Maintenance
Our systems are optimized for efficiency with minimal workforce requirements. Remote monitoring, automation, and low-energy processes ensure reliable performance with fewer resources.
-
Battery-Grade Output, On-Site
Our systems produce battery-grade lithium carbonate and hydroxide directly at your facility, eliminating the need for further refining downstream and accelerating your path to market.
Technical Advantages
When geothermal operators hear the term “lithium extraction,” they often envision a complex, chemical-intensive process that is challenging to integrate with power production. But that is not the case with Lithium Harvest’s modular system. Our technology is designed to work in harmony with geothermal operations - not disrupt them.
In short, this is not lab-scale tech or a black box. It is a robust, field-ready solution that has already been validated in industrial environments - and it is built to meet the performance standards of the industry.
Here are the key technical advantages that make our solution a smart fit:
-
Brine Chemistry Expertise
Not all geothermal brines are created equal. Some are high in lithium; others have challenging compositions, such as high salinity or interfering minerals. Our team has decades of experience in industrial water treatment and extraction, allowing us to tailor the process to your specific brine chemistry for maximum lithium recovery and efficiency.
-
Integrated Extraction + Refining
Many systems stop at pre-concentrated lithium or intermediate-grade output. Ours goes all the way. We extract and refine battery-grade lithium carbonate and hydroxide on-site, eliminating the need for external refining or off-site shipping, saving both time and cost.
-
Low-Energy Process
Traditional extraction methods consume large amounts of energy and water. Our process is engineered for geothermal compatibility, utilizing a low-energy, closed-loop system optimized for brine conditions, which means your plant can maintain efficiency and sustainability without compromise.
-
Automated & Digitally Monitored
The entire system is automated and remotely monitored, reducing the need for manual labor or on-site operators. It is as close to “hands-off” as lithium production gets, providing performance visibility without management overhead.
-
Minimal Interference with Power Production
Our solution is co-located but independent. It draws brine from the production cycle without interfering with energy output, ensuring no loss of geothermal performance. And if you are scaling power production, the system scales right alongside it.
-
Proven Technologies, Combined Innovatively
Our solution combines proven components from water treatment and separation science in a new, purpose-built configuration for lithium extraction. It is not experimental – it is smart innovation backed by operational know-how.
Rethinking Lithium Supply: Modular Systems Fit Geothermal Operations
Centralized lithium refining has long been the industry norm. Brines are extracted in one place, shipped hundreds or thousands of miles to another, and refined in mega-facilities that take years to build and cost hundreds of millions to operate.
That model was not made for geothermal - and it is quickly becoming outdated.
Here is why modular lithium extraction systems are a superior fit for geothermal energy companies:
-
Co-Location Means Synergy
With geothermal, the resource (brine) is already flowing. Why truck it out? Modular systems are built right next to the heat and the brine, making use of existing infrastructure and simplifying everything from permitting to process integration. It is a smarter use of your resources - and your land.
-
No Shipping, No Dilution
Centralized refining means shipping raw or semi-processed brine over long distances. It is expensive, inefficient, and environmentally questionable. Modular systems process lithium at the source, eliminating the need for transport and reducing emissions, water loss, and handling costs.
-
Customization > Standardization
Centralized systems prioritize volume over nuance. However, geothermal brines are not one-size-fits-all; they vary by location, depth, and composition. Our modular systems are tailored to your brine, allowing higher recovery rates and fewer process losses.
-
Supply Chain Resilience
In today’s geopolitical climate, localized production matters. Modular systems allow us to produce battery-grade lithium domestically, supporting national energy security and reducing reliance on foreign refining hubs.
-
Better for Business
Modular systems mean lower capital risk, faster returns, and flexible scaling. Instead of waiting 5–15 years for a centralized facility to break ground, you could be producing lithium - and revenue - in under 18 months without managing the operation yourself.
