Professor Scott Barnett, a specialist in Materials Science and Engineering at Northwestern University, will deliver a talk on 'High-Efficiency Energy Storage Using Reversible Solid Oxide Cells' at an event organized by the Department of Materials Science and Engineering. The presentation will highlight the critical role of electrical energy storage in facilitating the increased adoption of renewable energy sources like wind and solar power to reduce CO2 emissions. Various strategies involving reversible solid oxide cells for storing excess electricity and enabling grid-scale energy storage will be discussed, including the production of fuel for transportation and the concept of a flow battery. The talk will also cover the importance of developing improved solid oxide cells that can maintain high current densities with minimal degradation for economic viability. Additionally, ongoing research on enhancing the stability of solid oxide cells during electrolysis and reversing-current cycling will be presented, addressing key degradation mechanisms like oxygen electrode delamination and Ni migration in fuel electrodes. This event is open to faculty, staff, and students interested in renewable energy, energy storage technologies, and sustainable solutions for grid-scale energy applications.
