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.
A new study examines the technologies needed to produce renewable ammonia from offshore wind in the US, and analyzes the lifetime economics of such an operation.
This is the latest in a years-long series of papers by a team of researchers from the University of Massachusetts, Amherst, and Massachusetts Institute of Technology (MIT). And it is by far the closest they have come to establishing sustainable ammonia as being cost-competitive with fossil ammonia.
Last month's NH3 Energy+ conference featured presentations on a great range of novel ammonia synthesis technologies, including improvements to Haber-Bosch, and plasmas, membranes, and redox cycles. But, in a mark of a conference approaching maturity, members of the audience had at least as much to contribute as the presenters.
This was the case for electrochemical synthesis technologies: while the presentations included updates from an influential industry-academia-government collaboration, led by Nel Hydrogen's US subsidiary, the audience members represented, among others, the new electrochemical ammonia synthesis research lab at Massachusetts Institute of Technology (MIT), and a team from Monash University in Australia. The very next week, Monash published its latest results, reporting an electrochemical process that synthesized ammonia with 60% faradaic efficiency, an unprecedented rate of current conversion at ambient pressure and temperature.
In an interview today, Dr. Yaoli Zhang from Xiamen University discussed the case for integrating ammonia production with nuclear power. Dr. Zhang is currently a Visiting Professor at the Massachusetts Institute of Technology in Boston.
The idea would be to harness both unused generating capacity and waste heat to produce ammonia with a near-zero carbon footprint.
