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.

International R&D on sustainable ammonia synthesis technologies

Over the last few weeks, I've written extensively about sustainable ammonia synthesis projects funded by the US Department of Energy (DOE). While these projects are important, the US has no monopoly on technology development. Indeed, given the current uncertainty regarding energy policy under the Trump administration, the US may be at risk of stepping away from its assumed role as an industry leader in this area.

This article introduces seven international projects, representing research coming out of eight countries spread across four continents. These projects span the breadth of next-generation ammonia synthesis research, from nanotechnology and electrocatalysis to plasmas and ionic liquids.

US DOE funding research into sustainable ammonia synthesis

The US Department of Energy (DOE) is currently supporting six fundamental research projects that will develop "novel catalysts and mechanisms for nitrogen activation," which it hopes will lead to future sustainable ammonia synthesis technologies.

These projects, announced in August 2016 and administered by the Office of Basic Energy Sciences, aim "to investigate some of the outstanding scientific questions in the synthesis of ammonia (NH3) from nitrogen (N2) using processes that do not generate greenhouse gases."

ARPA-E’s vision for carbon neutral liquid fuels

We wrote last month about the US Department of Energy funding ammonia fuel projects through ARPA-E's "REFUEL" program ("Renewable Energy to Fuels through Utilization of Energy-dense Liquids").

Although we introduced the funded projects in both the ammonia synthesis category and the ammonia fuel-use category, the REFUEL project merits further analysis as a whole because it describes a roadmap for the development of ammonia fuel systems, and identifies benchmarks for their commercial success.

ARPA-E funding for renewable ammonia synthesis technologies

Last week, ARPA-E announced funding for eight technologies that aim to make ammonia from renewable electricity, air, and water.

The technological pathways being developed include adaptations of the Haber-Bosch process - seeking improvements in catalysts and absorbents - as well as novel electrochemical processes.

REFUEL Ammonia Use-Side Funding Awards

Six of the projects designated for funding by the ARPA-E REFUEL announcement on December 15 involve technologies on the use side of the ammonia energy space. Three focus on generating hydrogen from ammonia. Two focus on fuel cells that convert ammonia to electricity. One project involves both ammonia synthesis and use.

Grand Challenges in Sustainable Ammonia Synthesis – DOE Roundtable Report, 2016

Earlier this year, the US Department of Energy (DOE) hosted a day-long meeting "to explore the scientific challenges associated with discovering alternative, sustainable processes for ammonia production."

The report that came out of this roundtable discussion presents the participants' views on "the current state-of-the-art and the potential challenges and research opportunities ... for heterogeneous catalysis and homogeneous and enzyme catalysis."

ARPA-E’s “transformative” ammonia synthesis technologies

The US Department of Energy's Advanced Research Project Agency (ARPA-E) is funding projects with a view to commercializing low- and zero-carbon ammonia synthesis technologies.

Grigorii Soloveichik, ARPA-E Program Director, described the aims and challenges of his agency's initiative and introduced the technologies currently in development in his keynote presentation at the recent NH3 Fuel Conference, in September 2016.

US DOE: The REFUEL Project

In April 2016, the United States Department of Energy (DOE) released a Funding Opportunity Announcement (FOA) for its Renewable Energy to Fuels through Utilization of Energy-dense Liquids (REFUEL) program.

The focus of the program is carbon-neutral liquid fuels (CNLFs). In the DOE’s formulation, CNLFs are to be produced “from air and water using electrical or thermal energy from renewable sources.”
