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."
NEWS BRIEF: A new policy think tank was launched last month that will focus on "why and how Scotland could benefit from being an early adopter of renewable hydrogen." Its "core starting point" is CSIRO's hydrogen-purification membrane, which enables ammonia to be used and exported as an efficient hydrogen carrier; for this use, green ammonia would be produced from offshore wind. According to the founders, this could lead to "Scotland becoming one of the largest global energy exporters in the world ... it could be the country’s main source of energy and create a knowledge economy."
NEWS BRIEF: A research paper was published this week by researchers from Xiamen Univeristy in China, which "proposes a scheme for an ammonia-based energy storage system in which ammonia, an environmentally benign hydrogen carrier, is expected to [resolve] the conflicts of renewable energy supply and consumption in China."
