Panel discussion on next-generation ammonia synthesis

Kevin Rouwenhorst December 03, 2020

This year’s Ammonia Energy Conference included a panel discussion on next-generation ammonia synthesis, moderated by Sarb Giddey (CSIRO, Australia), and featuring panelists Doug MacFarlane (Monash University, Australia), Karthish Manthiram (MIT, United States), and Michael Stoukides (Aristotle University of Thessaloniki, Greece). The panel discussed the direct fixation of nitrogen in the form of ammonia from water and air in a single electrochemical device, which is considered the “holy grail” of ammonia synthesis. During the panel, the participants gave their perspectives on the state of the art, and the obstacles and opportunities for progress.

Electrified Methane Reforming Could Reduce Ammonia's CO2 Footprint

Kevin Rouwenhorst August 15, 2019

A May 2019 paper published in Science reports on a technological advance that may have significant implications for ammonia production. The paper, Electrified methane reforming: A compact approach to greener industrial hydrogen production, presents a method for providing the heat required for steam methane reforming from renewable electricity instead of natural gas. The carbon intensity of ammonia production could thereby be reduced by about 30%. And, last month, Haldor Topsøe announced that it plans to build a demonstration plant in Denmark that will produce “CO2-neutral methanol from biogas using eSMR technology.” The plant is expected to be “fully operational in the beginning of 2022.”
