The world’s largest battery reservoir can be found in Bolivia, with 23,000,000 tonnes of lithium having been found rather close to America. Below the salt flats is a resource that is central to the global energy transition. The reason that this has become all the more interesting and why all the attention has fallen on the Andes is due to the fact that the demand for electric vehicles has escalated.
Salar de Uyuni is becoming a point of interest
Salar de Uyuni is the largest salt flat that covers over 10,500 square kilometers, and hidden beneath the crust here is 23 million metric tons of lithium. Since lithium is rather important for lithium-ion batteries used to power electric vehicles and renewable energy storage, this finding is rather valuable globally.
Bolivia’s proximity to markets in North and South America makes it of more importance geographically. The problem arises when it comes to turning these findings into usable lithium. For now, Bolivia’s lithium is contained in brine. Brine is a groundwater mixture that is complicated to extract. The region is still undergoing many debates regarding the long-term environmental risks in terms of extracting the usable lithium.
What environmental complications does extracting lithium from brine pose?
Researchers at Duke University considered what would happen in terms of the environment if lithium were extracted from brine at Salar de Uyuni. Natural underground brine showed arsenic levels between one and nine parts per million, and the acidity was relatively neutral. However, when brine moves through evaporation ponds, the acidity increases rather severely. In the final ponds, acidity levels were more than 50 parts per million, posing somewhat of a threat since this means it is 1,500 times higher in acidity than what is considered ecologically safe, as per the U.S. Environmental Protection Agency Standards.
In a place like Bolivia, where water scarcity is already a concern, any other form of environmental concern could seriously gain negative feedback. The question is whether this large-scale extraction would result in irreversible damage.
Some resistance to contracts and going ahead with lithium extraction from brine
Since Yacimientos de Litio Bolivianos (YLB) signed the contracts with Russian and Chinese firms, it shows that the country’s lithium goal has increased significantly. With facilities set to produce 90,000 tons of lithium annually, it will be able to supply many electric vehicles.
Residents of Bolivia, however, are not exactly thrilled. They mention that the water shortages already exist, and these citizens fear that lithium extraction processes may result in further water shortages. The fear is that lithium projects may even take some water away from the farming and agricultural sectors. Community leaders have gone a step further and criticized lithium projects for the lack of environmental assessment. The truth is that with one state emerging as the lithium-magnet heartland, it is starting to spell the end for China and Russia.
Bolivia is attempting to secure a clean energy future with 23,000,000 tonnes
With the country being so close to America, it is only understandable why Bolivia is so enthusiastic about tapping into its lithium potential. However, it is not as clear-cut since Bolivia’s clean energy future at Salar de Uyuni is linked to water, culture, and climate.
Lithium extraction can carry with it environmental risks if it is not properly managed. This country will have to assess the readiness of direct lithium extraction (DLE) technology and only push the project of extracting lithium from brine forward if it poses no real environmental risks in the process. While Bolivia remains ambitious about its clean energy future, the massive U.S. white gold deposit stuns the world and seems like a game-changer for decades.
