DLE is gaining traction as a potential route to unlock domestic lithium supply in Europe, particularly from more complex and previously uneconomic resources. While technology is advancing rapidly, the key question is whether it can deliver consistent, cost-effective production at scale. ' What has been demonstrated at scale ' and where are the remaining technical and operational gaps? ' How are different DLE technologies performing across varied brine compositions? ' Can technological innovation improve recovery rates and reduce costs? ' Where have we seen successful DLE projects globally, and what can Europe learn from them? ' What needs to be proven for projects to secure financing and offtake? ' When could DLE become a reliable source of supply for Europe?
