Virtual Plants, Real Lithium: How DLE Is Scaling Smarter

Early projects use virtual modelling to cut risk as direct lithium extraction moves towards commercial deployment

2 Dec 2025

Europe’s drive to secure a domestic supply of lithium is moving into a more demanding phase, with early projects showing how digital tools can help direct lithium extraction scale more predictably. As the technology shifts from pilot testing towards initial commercial use, developers are turning to digital twins to manage technical risk and speed up development.

Demand for lithium continues to rise as electric vehicle production expands, while governments and manufacturers seek supply that is reliable, traceable and less carbon intensive. Direct lithium extraction, which recovers the metal from underground brines rather than open evaporation ponds, is seen as a faster and potentially cleaner alternative. However, moving from laboratory success to stable industrial operation remains complex.

Digital twins, virtual replicas of industrial systems, are increasingly being used to address that challenge. By modelling plant behaviour in software, developers can test operating conditions, refine designs and identify constraints before making changes on site. The approach reduces reliance on trial and error during scale-up, which can be costly and time-consuming.

Recent industry activity highlights the trend. Siemens has described how advanced process modelling is being applied to lithium extraction projects, including work with developers such as Lithium Harvest. These collaborations focus on analysing how changes in brine chemistry or operating parameters affect performance, with the aim of improving reliability as capacity increases.

Lithium Harvest has said digital modelling forms part of its strategy to advance projects while keeping costs under control. Virtual testing allows earlier decisions to be taken with greater confidence, a significant advantage in a sector where delays can undermine commercial viability.

Analysts see this as part of a wider shift in the development of critical minerals. Rather than relying solely on physical pilot plants, companies are combining real-world data with digital simulation. The hybrid approach offers clearer insight into performance limits and cost drivers as projects move towards larger scale.

The use of digital twins can also extend into operations. Once plants are running, models can help detect early signs of equipment stress or declining performance, supporting preventative maintenance and more stable output. For battery makers and car manufacturers, consistency of supply is increasingly important.

Although digital twins are not yet standard across the direct lithium extraction sector, their use is expanding. As Europe advances policies such as the Critical Raw Materials Act to strengthen its battery supply chain, digital tools are becoming part of how developers seek to turn emerging technology into dependable production.
