This webinar discusses tradeoffs in high-pressure steam electrolysis, and describes testing novel materials and manufacturing for solid oxide electrolyzers. System-level opportunities are described for pressurized steam electrolysis to significantly reduce energy consumption of hydrogen production and open the door for co-electrolysis and direct synthesis of methane or ammonia e-fuels. The potential economics of pressurized solid oxide electrolysis are compared with the emerging PEM electrolyzer market. Dr. McLarty’s Washington State University (WSU) team tested commercial-scale solid oxide cells at up to 10 bar, reinforcing how vexing the material degradation challenge is for pressurized operation of strontium containing electrodes on YSZ electrolytes. This challenge led to pursuing new electrode materials with the defect-cubic structure of stabilized zirconia, and a new monolithic stack production method that can take advantage of the higher density reactant gases in a pressurized system. The discussion concludes with a description of WSU’s material and stack production and 100 bar testing capabilities.
Benefits of attending the webinar
- Pressurized operation of solid oxide cells, trade-offs in performance and economics;
- EIS testing of vanadia-doped zirconia electrodes;
- Testing facilities available for collaboration at WSU.
Dr. Dustin McLarty is Assistant Professor in the School of Mechanical and Materials Engineering at Washington State University. He holds an MS and PhD in Mechanical Engineering from the University of California, Irvine, and BSc in Aerospace Engineering from the University of Florida. Dr. McLarty studies high temperature fuel cells, and the dynamics and controls of advanced micro-grids. The research expands upon previous systems integration experience garnered in Irvine, CA; Boulder, CO; Birmingham, UK; and Morgantown, WV. Involved in research for clean energy systems, Dr. McLarty worked with industry partners and national labs to develop systems integration solutions and novel electrochemical power concepts. A lifelong competitive swimmer who represented the US national team at international competitions, Dr. McLarty also served as a professional surf lifesaver at Daytona Beach, FL, and Huntington Beach, CA.
