At the recent NH3 Energy+ Topical Conference, Grigorii Soloveichik described the future of ammonia synthesis technologies as a two-way choice: Improvement of Haber-Bosch or Electrochemical Synthesis.
Two such Haber-Bosch improvement projects, which received ARPA-E-funding under Soloveichik's program direction, also presented papers at the conference. They each take different approaches to the same problem: how to adapt the high-pressure, high-temperature, constant-state Haber-Bosch process to small-scale, intermittent renewable power inputs. One uses adsorption, the other uses absorption, but both remove ammonia from the synthesis loop, avoiding one of Haber-Bosch's major limiting factors: separation of the product ammonia.
During our NH3 Energy+ Topical Conference, hosted within AIChE's Annual Meeting earlier this month, an entire day of presentations was devoted to new technologies to make industrial ammonia production more sustainable.
One speaker perfectly articulated the broad investment drivers, technology trends, and recent R&D achievements in this area: the US Department of Energy's ARPA-E Program Director, Grigorii Soloveichik, who posed this question regarding the future of ammonia production: "Improvement of Haber-Bosch Process or Electrochemical Synthesis?"
In late August, the day before the exciting solar eclipse, the Ammonia Economy symposium was held as part of the Energy and Fuels Division of the American Chemical Society (ACS) National Meeting in Washington DC. This marks the third gathering of Ammonia related research since 2015 at the national level ACS conference. This year, in addition to the important focus on chemistries for the utilization of ammonia, the rapidly developing field of homogeneous catalysts and biological processes for nitrogen fixation was included as a major theme.
The NH3 Fuel Association has finalized details of its Sponsors Reception on Wednesday November 1 at the AIChE Annual Meeting in Minneapolis, and has also announced an additional sponsor for the conference: Starfire Energy.
Eric McFarland, Professor of Chemical Engineering at the University of California Santa Barbara, likes fossil fuels and nuclear energy and is unimpressed by the menu of renewable energy technologies. But he is worried about climate change and he has an original view on how to modify our current energy system so that we don’t overload the atmosphere with CO2. He believes the key will be to separate fossil hydrocarbons into gaseous hydrogen and solid carbon. The chemistry he is developing in this area involves transferring “electrochemical potential” from hydrocarbons to alternative energy carriers. Ammonia is an energy carrier that McFarland believes is especially promising.
