At Licube, our technology is designed to work seamlessly with any type of brine — from salt lakes and geothermal sources to battery recycling and oilfields. Among these, oilfield brine represents one of the most exciting opportunities for innovation and growth.

Why oilfield brine?

The answer lies in both its challenge and potential. Extracting lithium from oilfield brine is notoriously difficult, making it less viable for many existing technologies. Yet across the United States and beyond, many DLE companies are already developing extraction projects to unlock this resource.

This is where Licube comes in.

Instead of competing in extraction, we collaborate and co-locate with DLE operators — adding the refining stage that transforms their extracted lithium chloride or carbonate feed into ultra-high-purity lithium hydroxide (≥99.99%).

By combining their DLE capability with our electrodialysis-based polishing technology, we enable the production of 4N-grade lithium locally, right at the source.

In other words, any country with brine can now produce 4N-grade lithium — without exporting intermediate materials or relying on overseas refiners.

Internationally Scalable

Existing oilfield infrastructure provides a powerful foundation for rapid deployment.

Based in Houston, Texas, near the Smackover Formation, Licube is ideally positioned to work directly with U.S. DLE operators and oil producers. Together, we’re building a fully integrated, low-carbon supply chain from oilfield brine to ultra-pure lithium hydroxide.

This model can be replicated globally. By co-locating refining systems with local DLE plants, Licube helps create regional refining capacity — allowing partners around the world to turn their brine into 4N-grade lithium products for high-performance markets.

Oilfield brine is no longer a challenge to manage — it’s a gateway to a more sustainable and diversified lithium future.

At Licube, we’re turning waste into value and helping every nation produce its own 4N lithium.
