Electrochemical Promotion of Ammonia Synthesis with Proton-Conducting Ceramic Fuel Cells -Function of Electrode Interface for Ammonia Formation Reaction-
NEWS BRIEF: The industrial process for ammonia production is increasingly being recognized as a target for decarbonization - by researchers, investors, regulators, and the producers themselves. Demonstrating this shift in awareness, Chemical and Engineering News (C&EN), one of the flagship publications of the American Chemical Society (ACS), this week published an in-depth review of global research and development efforts and demonstration plants for sustainable ammonia synthesis. Its review is all-encompassing, from near-term feasible renewable Haber-Bosch plants, to long-term research areas of electrochemistry, photocatalysis, and bioengineering.
NEWS BRIEF: A paper published this week in Nature addresses the challenge of accurately reporting synthesis rates for electrochemical ammonia production technologies. According to the authors, from Stanford University, the Technical University of Denmark (DTU), and Imperial College London, it is not always clear if new technologies really synthesize ammonia, or if the researchers simply measured contaminants. This is because, at experimental scale, materially significant amounts of ammonia (or other nitrogen-containing molecules) could be present in the air, membranes, catalysts, or simply the researchers' breath. To support the development of viable electrochemical ammonia synthesis technologies, the authors propose "benchmarking protocols," and "a standardized set of control experiments."
The journal Advanced Materials recently published an article that reviews electrochemical ammonia technologies for both synthesis and power generation. In addition to presenting a range of technologies under development, the authors, based at the University of Delaware, present "perspectives in the technical challenges and possible remedies."
