We attended the DLES UK 2026 conference, where lithium producers, technology providers, engineering companies, and investors gathered to discuss the current state of Direct Lithium Extraction (DLE).
Compared to many technical conferences, the discussions this time felt more grounded.
Instead of focusing on whether DLE works, most conversations were centered around:
- how to scale
- how to control cost
- how to make projects actually move forward
It was clear that the industry is moving into a more practical stage.
The Industry Is Moving Beyond “Technology Validation”
One of the clearest signals from DLES UK 2026:
The industry is no longer asking whether DLE works —
it is asking who can make it work at scale.
Several projects have already demonstrated:
- Lithium recovery >90%
- Stable lab and pilot performance
- Feasibility across different brine types
However, the bottleneck has shifted to:
- Engineering integration
- Process stability
- Cost control
- Long-term operation
This is where many projects start to slow down.
No One-Size-Fits-All Solution (And That’s the Core Problem)
A recurring consensus across multiple speakers:
There is no universal DLE solution.
This aligns strongly with real project experience:
- Different brines = completely different challenges
- High Mg/Li ratio ≠ same strategy
- Oilfield brine ≠ salt lake brine
- Geothermal ≠ industrial wastewater
From a process perspective, relying on:
- a single adsorbent
- or a single technology route
is simply not practical.
Instead, success depends on process design + integration.
Process Design Is Becoming More Important Than Materials
This was probably the most underrated but critical takeaway.
Across discussions, one theme kept appearing:
👉 Pretreatment
👉 Flow design
👉 pH control
👉 Multi-stage systems
In fact, many failures in DLE projects are not due to the adsorbent or membrane itself, but due to:
- Poor pretreatment (oil, organics, solids not removed)
- Unstable pH during adsorption
- Scaling during desorption
- Incomplete system design
A well-designed process can make an average material perform well.
A poorly designed process can destroy even the best material.
Adsorption Technology: Still One of the Most Practical Routes
Among all DLE technologies discussed (membranes, solvents, electrochemical, etc.),
adsorption remains one of the most widely applied and closest to industrial reality.
Why?
- Simple operation
- Mature engineering compatibility
- Scalable column-based systems
- Lower operational complexity
Typical configurations mentioned:
- Fixed bed
- Moving bed
- Simulated moving bed (SMB)
Each has its own trade-offs depending on:
- flow rate
- pressure
- brine composition
What Lithium Producers Actually Care About
From conversations and presentations, lithium developers are focusing less on theory and more on:
1. Stability
Can the system run for hundreds or thousands of cycles?
2. Cost
CAPEX + OPEX — not just recovery rate
3. Risk
Can this be financed? Can it be built?
4. Integration
How does it fit into the full flowsheet?
Interestingly, many companies are becoming more cautious —
waiting for “perfect solutions” rather than moving forward.
The Hidden Risk: Waiting Too Long
Here’s a slightly sharper observation.
Many Western projects are:
- Technically sound
- Financially backed
- But slow in decision-making
Meanwhile, the market is moving fast.
Projects that:
- accept “good enough” solutions
- move into pilot and industrialization early
are more likely to capture market opportunities.
Waiting for the “best possible technology” often means:
👉 Missing the window entirely
Final Thoughts: DLE Is Now an Engineering Game
If there’s one sentence to summarize DLES UK 2026:
DLE is no longer a materials competition — it is an engineering competition.
The winners will not be those with:
- the highest lab performance
But those who can:
- integrate technologies
- design robust processes
- scale reliably
- control cost
Looking Forward
As DLE continues to evolve, collaboration between:
- material suppliers
- engineering companies
- lithium producers
will become increasingly critical.
Because in reality:
No single player can solve the full process alone.
