University of Minnesota demonstrates efficient ammonia dual-fuel engine system

This month, researchers at the University of Minnesota began successful field tests of their new ammonia engine, operating a heavy-duty tractor across farmland near Morris, MN, on a dual-fuel blend of 70% diesel and 30% ammonia.

The global quest to decarbonize ammonia production

NEWS BRIEF: The industrial process for ammonia production is increasingly being recognized as a target for decarbonization - by researchers, investors, regulators, and the producers themselves. Demonstrating this shift in awareness, Chemical and Engineering News (C&EN), one of the flagship publications of the American Chemical Society (ACS), this week published an in-depth review of global research and development efforts and demonstration plants for sustainable ammonia synthesis. Its review is all-encompassing, from near-term feasible renewable Haber-Bosch plants, to long-term research areas of electrochemistry, photocatalysis, and bioengineering.

Heavy-duty diesel trucks to be converted to use ammonia fuel in Canada

This week, Hydrofuel Inc announced a commercial demonstration project to convert diesel gensets and transport trucks to run on ammonia fuel, with the conversion work and dual-fuel operations scheduled for a three year period.

The CAD $2 million (USD $1.5 million) project will take place at TFX International, in Toronto, and involves the conversion of four existing diesel-fueled assets: two stationary power generators and two transport trucks. These will be converted using Hydrofuel's "aftermarket multi-fuels engine retrofit systems," and they will thereafter be able to operate on a dual fuel basis.

AEA Australia conference announced for August 2019: Ammonia = Hydrogen 2.0

ANNOUNCEMENT: The Australian chapter of the Ammonia Energy Association (AEA Australia) has announced details of its inaugural conference, which will take place on August 22 and 23, 2019, and will be held at CSIRO in Clayton, Victoria.

Entitled "Ammonia = Hydrogen 2.0," the conference will focus on the role of ammonia within the Australian hydrogen economy, specifically "Building an energy export industry using Green Ammonia." In addition to a full program of talks by invited speakers, networking events will include panel discussions, a poster session, and the conference dinner. Registration for the event is now open, with an early booking discount available until July 5.

Sailing on Solar: EDF report identifies ammonia as “one of the most promising” maritime fuels

In May, the Environmental Defense Fund published Sailing on Solar, a significant new report that assesses the potential for green ammonia to be used as a maritime fuel, reducing the global shipping industry's carbon emissions.

Its 60-page techno-economic analysis concludes that "green ammonia can – indeed should – be adopted as a greenhouse gas-free fuel more easily, quickly and safely than people may assume." Indeed, Sailing on Solar estimates that, to meet decarbonization targets, ammonia will need to start being adopted in ships "during the 2020s."

A rigorous protocol for measuring electrochemical ammonia synthesis rates

NEWS BRIEF: A paper published this week in Nature addresses the challenge of accurately reporting synthesis rates for electrochemical ammonia production technologies. According to the authors, from Stanford University, the Technical University of Denmark (DTU), and Imperial College London, it is not always clear if new technologies really synthesize ammonia, or if the researchers simply measured contaminants. This is because, at experimental scale, materially significant amounts of ammonia (or other nitrogen-containing molecules) could be present in the air, membranes, catalysts, or simply the researchers' breath. To support the development of viable electrochemical ammonia synthesis technologies, the authors propose "benchmarking protocols," and "a standardized set of control experiments."

NH3 Event in Rotterdam, June 6-7

This year's ammonia conference in Rotterdam, the third annual NH3 Event, begins two weeks from today. Since our guest post in March, announcing the initial roster of conference speakers, the organizers have confirmed new speakers, added more sessions, and announced further details.

The NH3 Event is a two-day conference, taking place on June 6 & 7, presenting "state of the art solutions and innovations on the subject of Sustainable Ammonia." Although the conference hall is already close to capacity, a few dozen tickets remain available through the NH3 Event website.

Ammonia-fed microbial fuel cells: power from sweat

NEWS BRIEF: The National Science Foundation has awarded $452,000 to researchers at Binghamton University to develop a technology that can generate power from sweat, fueling "one of the ultimate forms of next-generation electronics." The project aims to harness ammonia-oxidizing bacteria, using microbial fuel cells, to power wearable electronics.

Feeding Life 2030: the vision of Fertilizers Europe

Fertilizers Europe published an important report in late 2018 that examines key drivers for the fertilizer industry and describes the "likely developments expected between now and 2030." These developments include producing "perhaps 10%" of European ammonia from renewable electricity by using electrolyzers to generate renewable hydrogen feedstock. This would require scaling up green ammonia production capacity to more than a million tons per year, within ten years.

The report, Feeding Life 2030, also describes the policy framework required "to sustain the Vision." In this vision, ammonia sits at "the crossroads of nutrition and energy" and is recognized as "the ‘missing link’ in the coming energy transformation."

ARPA-E solicits technologies for nitrogen extraction from seawater using seaweed

NEWS BRIEF: On Monday, May 13, the US Department of Energy ARPA-E will close its request for information (RFI) regarding Quantification of Effectiveness of Nutrient Bioextraction by Seaweed.

By using environmental remediation (nitrogen removal) as a mechanism for ammonia production (nitrogen recycling), this novel research area could connect together two phases of industry: production and end-of-life management. Rather than saying that this addresses both ends of a value chain, it might be more appropriate to say that this holds promise for the circular economy of ammonia energy.
