Concerns around sustainability and the security of global supply chains could boost opportunities related to direct lithium extraction.
The project in Cornwall is focused on direct lithium extraction, or DLE. According to the U.S. Department of Energy's National Renewable Energy Laboratory, the technologies behind DLE "can be broadly grouped into three main categories: adsorption using porous materials that enable lithium bonding, ion exchange, and solvent extraction."
"For example, developing a solid material that bonds with just lithium is a huge challenge in geothermal brine that contains many minerals and metals," it says.Projects such as the one in Cornwall come at a time when concerns around sustainability and ESG are mounting. The security of global supply chains is another issue, especially when the vast majority of lithium production is currently dominated by countries including Chile, China, Australia and Argentina.
Major economies and automotive manufacturers are also laying out plans to increase the number of electric vehicles on our roads. Simultaneously, the push to expand renewable energy capacity shows no sign of letting up. When it came to the sustainable sourcing of lithium and other materials, Poliscanova said that, "mid to long term, it's clear that the vast majority of it has to come from circular business models, most notably recycling."
