Lithium may be a tiny element, but it plays a huge role in the renewable energy transition. It’s the key ingredient in electric vehicle batteries, smartphones, and energy storage systems. But before lithium can power your life, it has to be refined.
Currently, lithium is extracted from two main sources: spodumene, found in Australia, and brine, located in the salt flats of South America.
But the processes are slightly different. Spodumene is mined, crushed, and then treated through acid-roasting. For brine extraction, salt-rich water is pumped from underground reservoirs into surface evaporation ponds, where, over several months, the water gradually evaporates, causing various salts to crystallize and separate.
At this stage, lithium concentrate generally contains only 5-6% lithium, while battery-grade lithium requires a purity of 99.99%. Today, roughly 75% of the world’s lithium is refined in China.
We have set out to change this and provide European cell manufacturers with a local, resilient supply chain.
The UK has two major competitive advantages; chemical parks and bad weather. Chemical parks, meaning dedicated production sites, and bad weather, meaning strong offshore winds.
Tees Valley Lithium aims to establish the UK’s first low-carbon lithium refinery. It is strategically located in a large chemical park in Teesside in the North East of England, which is connected to one of the world’s largest offshore wind farms, Dogger Bank.
TVL is a refiner not miner, building lithium supply chains in the UK and Europe, reducing reliance on a single dominant market, and supporting the global energy transition.
