In 2019, The National Academies issued a report entitled 'A Research Agenda for Transforming Separation Science.' 10 to 15% of energy consumption in industrialized economies come from chemical separations. Addressing climate change while lifting people out of poverty will require transformative breakthroughs in the way we perform separations. Furthermore, some of the most challenging separations of today overlap with other important research priorities such as securing critical minerals (e.g., lithium and other precious minerals), remediation of water (e.g., PFAS and heavy metal removal, desalination), gas separations (e.g., hydrogen and carbon dioxide removal/direct air capture), purification of valuable organic acids from processed biomass, nutrient recovery (e.g., nitrogen and phosphorus species from agricultural runoff), and battery component recycling. Various embodiments of electrochemical separations are emerging to meet the said challenges. Because electrochemical separations are electrified, they can be powered on renewable electrons from solar and wind and can have a profound impact in reducing greenhouse gas emissions from various industrial sectors. Central to advancing electrochemical separations technology is unlocking knowledge that governs the interfacial phenomena at electrode, membrane, and fluid interfaces. This workshop will attract several thought leaders in electrochemical separations. We anticipate having speakers with expertise in different areas - such as cell/system design, electrode and membrane materials, and modeling across various length scales.
