Seawater Lithium Extraction

Seawater: Transforming EV Battery Lithium Extraction

Electric vehicle batteries currently rely on lithium, a mineral whose extraction from traditional land-based reserves poses significant environmental challenges. However, a potential solution lies within the vast resources of seawater. Recent developments showcase the immense promise of seawater, which harbors approximately 230 billion tonnes of lithium, compared to the mere 21 million tonnes found in terrestrial deposits. A pioneering collaboration between the King Abdullah University of Science and Technology and Saudi mining company Ma’aden has commenced extracting lithium from the Red Sea utilizing “proprietary ceramic membrane-based technology”. While specific details of the extraction process remain guarded, experts express confidence in its efficacy. Remarkably, it is estimated that extracting a mere 0.1% of lithium from seawater could adequately fulfill global technological demands.

Extracting lithium from seawater has several key benefits. Firstly, it gives us access to a huge amount of lithium because seawater contains a lot more of it than we can find on land. This means we don’t have to worry as much about running out of lithium or about fighting over limited resources. Secondly, extracting lithium from seawater doesn’t harm the environment as much as traditional mining methods do. It helps reduce damage to habitats, pollution of water sources, and greenhouse gas emissions. Plus, it’s a cheaper and more sustainable way to get the lithium we need for things like electric cars and electronic devices. By tapping into the power of the ocean, we’re taking a big step towards cleaner and more eco-friendly technologies for the future.
