Progress for Low-Temperature Direct Ammonia Fuel Cells

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.

Improvement of Haber-Bosch: Adsorption vs. Absorption

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.

ARPA-E talks advanced hybridization, carbon-neutral liquid fuels

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.

Overcoming the Selectivity Challenge in Electrochemical Ammonia Synthesis

In the last 12 months ...
The research community has made great progress toward solving the "selectivity challenge" in electrochemical ammonia synthesis. Although, rather than an actual solution, mostly what we have is a range of sophisticated work-arounds that succeed in making this problem moot.

Ammonia Energy Gains Recognition from U.S. Department of Energy

In the last 12 months ...
Ammonia energy has gained recognition from the United States Department of Energy, in both bottom-up and top-down programs. This establishes ammonia energy in the world’s largest economy as a legitimate target for both public- and private-sector investment.

REFUEL Is Back on Track

The U.S. Department of Energy’s ARPA-E REFUEL Program, whose continued existence seemed to be in doubt two months ago, now appears to be back on track.  Invitations were sent a week ago for the ARPA-E REFUEL Program Kickoff, an event that was originally scheduled for April 25 and 26 in Houston.  It is now scheduled to take place in Denver on August 16, 17, and 18.  Attendance will be by invitation only.

Ammonia Energy at the H2@Scale Workshop

“Carbon-free ammonia needs to be a significant contributor to the H2@Scale initiative.” This was one of the “key takeaways” offered by Steve Szymanski, Director of Business Development at the hydrogen generator company Proton On-Site, during his presentation at the H2@Scale Workshop that was held on May 23-24 at the University of Houston in the U.S. By the time Szymanski left the podium, ammonia energy had moved a good distance from the periphery of the H2@Scale conceptual map toward its center.

The new generation of fuel cells: fast, furious, and flexible

At ARPA-E's recent Energy Innovation Summit in Washington, DC, Program Director Grigorii Soloveichik presented his vision for the future of transportation: hybrid electric vehicles that combine the advantages of both plug-in battery and fuel cell technologies.

This "optimal solution" will require a new generation of fuel cell that is "fast, furious, and flexible." Fast, in terms of start-up / shut-down time. Furious, in terms of energy density. And flexible, in terms of fuel choice - specifically sustainable liquid fuels, like ammonia.
