The modern world runs on electronic devices and energy systems that are powered by valuable elements such as lithium and uranium. There are a limited number of terrestrial mines that produce energy-critical elements, which makes the supply of these materials prone to disruption. So researchers are looking to an unconventional source: seawater. Almost every element on the periodic table can be found in global oceans–but most are dissolved in ultralow concentrations. In this episode of Stereo Chemistry, we'll hear from scientists in the United States and European Union about why they're interested in extracting metals and minerals from seawater and how they're using chemistry to do it.
