Cornish Lithium's Cross Lanes Geothermal Lithium Project has achieved a significant milestone with the completion of a lined lagoon, crucial for the upcoming exploration phase. This development is pivotal as the project awaits the Final Investment Decision (FID), marking a step forward in Cornwall's resurgence as a domestic lithium source.
What Happened
Sean Carr Lining Technology (SCLT), a specialist in geosynthetic linings, has successfully completed the construction of a high-performance lined lagoon at the Cross Lanes site near Truro, Cornwall. This lagoon will temporarily store underground water extracted from geothermal brines during planned drilling and testing. The extracted water will eventually be returned underground. Cornish Lithium plans to drill two wells to assess the lithium content of the geothermal waters circulating beneath Cornwall. This data will be crucial for informing the final investment decision and developing a network of modular geothermal lithium production facilities across the county.
The project received a boost from a £31 million funding by the National Wealth Fund (NWF), underscoring the importance of lithium in the UK Government's Vision 2035 strategy, which identifies lithium as a critical mineral. Cornish Lithium is exploring extraction from both geothermal brines and hard rock, such as granite, with agreements covering a large area of Cornwall.
Why It Matters for the AECM Industry
For the architecture, engineering, construction, and manufacturing sectors, this development signifies a critical step towards establishing a domestic supply chain for lithium, essential for lithium-ion batteries used in electric vehicles, consumer electronics, and grid-scale storage. The completion of the lagoon by SCLT, a company with over 30 years of experience, highlights the growing demand for specialized construction techniques and materials, such as geosynthetic liners, in supporting new energy projects. This project not only fosters skilled labor and technical expertise but also contributes to reducing the environmental impact through careful planning and execution.
The success of the Cross Lanes project can serve as a model for similar initiatives, emphasizing the need for collaboration with specialist contractors to meet technical demands and deliver high-quality infrastructure. Moreover, it aligns with the broader goals of the low-carbon transition by supporting the development of a sustainable and secure supply of critical minerals.
What's Next
As the Cross Lanes project moves forward, the focus will be on the drilling and testing phases, with results expected to inform the final investment decision. The success of these phases is crucial for the proposed establishment of a network of geothermal lithium production facilities across Cornwall. Industry professionals should monitor developments closely, as these could influence project timelines and the availability of domestic lithium resources by 2030, aligning with government objectives.
