New lithium extraction process from MIT startup could lower costs and emissions
The article covers a new lithium extraction process developed by MIT professor Yet-Ming Chiang and commercialized by startup Rock Zero. The method aims to extract lithium from brine more efficiently than current techniques, potentially cutting costs and carbon emissions. Current methods — evaporation ponds from brine and hard-rock mining — are geographically limited or environmentally intensive. The new process could unlock more accessible, lower-cost lithium production critical for batteries and the clean energy transition.
Key quotes
At scale, we believe this will be the lowest-cost way of sourcing lithium in the world
The most economical way to get lithium currently is to extract it from brine, salty water that's pulled the metal out of rock over the course of millennia
