Shimshon Gottesfeld’s paper The Direct Ammonia Fuel Cell and a Common Pattern of Electrocatalytic Processes leads with a big number: “A record power density of 450 mW/cm2 has been demonstrated for a direct ammonia fuel cell [DAFC] using an alkaline membrane electrolyte.” We know it’s big because it’s 80% higher than the 250 mW/cm2 that Gottesfeld’s team had achieved in the fall of 2017 and that Gottesfeld, Adjunct Professor of Chemical Engineering at the University of Delaware, reported at the November 2017 NH3 Energy+ Topical Conference.
The 2018 NH3 Energy Implementation Conference, the first of its kind, took place on November 1 in Pittsburgh, Pennsylvania in the U.S. The focus of the Conference was on steps – current and future – that will lead to implementation of ammonia energy in the global economy. At the highest level, the Conference results validated the relevance and timeliness of the theme. In the words of closing speaker Grigorii Soloveichik, Director of the U.S. Department of Energy’s ARPA-E REFUEL Program, the Conference strengthened his confidence that “ammonia is a great energy carrier ... with billions of dollars of potential in prospective markets.”

IHI Corporation tested its 1 kW ammonia-fueled solid oxide fuel cell (SOFC) in Japan; Project Alkammonia concluded its work on cracked-ammonia-fed alkaline fuel cells (AFC) in the EU; the University of Delaware's project for low-temperature direct ammonia fuel cells (DAFC) continues with funding from the US Department of Energy's ARPA-E; and, in Israel, GenCell launched its commercial 4 kW ammonia-fed AFC with field demonstrations at up to 800 locations across Kenya.
Yara International, one of the world’s largest ammonia producers, is making strides in its development of green ammonia as a fertilizer, chemical intermediate, and energy carrier. The progress is documented in the company’s 2017 annual report, released last week, and in more detail in a presentation delivered in late February at the 2018 Nitrogen + Syngas Conference in Gothenburg, Sweden.
The second annual European Conference on Sustainable Ammonia Solutions has announced its full program, spread over two days, May 17 and 18, 2018, at Rotterdam Zoo in the Netherlands. The international cadre of speakers, representing a dozen countries from across Europe as well as the US, Canada, Israel, and Japan, will describe global developments in ammonia energy from the perspectives of industry, academia, and government agencies.
This series of articles on the future of ammonia synthesis began with a report on the NH3 Energy+ conference presentation by Grigorii Soloveichik, Program Director at the US Department of Energy's ARPA-E, who categorized the technologies as being either improvements on Haber-Bosch or electrochemical (with exceptions).
ARPA-E invests in "transformational, high-risk, early-stage research," and recently began funding ammonia synthesis technologies, not to make renewable fertilizer but to produce "energy-dense zero-carbon liquid fuel." This article will introduce the six electrochemical technologies currently in development with funding from ARPA-E.
Speaking at the NH3 Energy+ Topical Conference last month, University of Delaware Adjunct Professor Shimshon Gottesfeld reported on progress made by the university’s direct ammonia fuel cell (DAFC) project. Evidently, the UDel team is now a big step closer to its goal of establishing the DAFC as a viable automotive power plant.
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.
In the race to place the automotive sector on a sustainable footing, the field is dominated by just two horses: battery-electricity and hydrogen fuel cells. The economic implementation of BEVs is already well underway, with motor companies on track in 2017 to sell more than a million vehicles globally for the first time. The economic implementation of FCVs is also in progress, albeit at a much earlier stage, and has the backing of major motor companies and public-sector agencies. Given the huge leads enjoyed by electricity and hydrogen, ammonia is scarcely seen as a contending fuel. Earlier this month, though, the U.S. Department of Energy’s ARPA-E unit published an interview with two of its program managers that has an intriguing implication: the race is far from over and ammonia may yet break to the front of the pack.
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.
