Last month, an important new consortium in the Netherlands announced its intention to research and demonstrate "the technical feasibility and cost effectiveness of an ammonia tanker fuelled by its own cargo." This two-year project will begin with theoretical and laboratory studies, and it will conclude with a pilot-scale demonstration of zero-emission marine propulsion using ammonia fuel in either an internal combustion engine or a fuel cell.
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.
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.
A new study has made a major addition to the available literature on the economic benefits of ammonia energy. This latest study, published by researchers from CSIRO in Australia, provides the data needed to define the round-trip efficiency of using ammonia as a sustainable fuel and hydrogen carrier.
To demonstrate the progress of the SIP "Energy Carriers" program, the Japan Science and Technology Agency last week released a video, embedded below, that shows three of its ammonia fuel research and development projects in operation.
R&D is often an abstract idea: this video shows what it looks like to generate power from ammonia.
As it turns out, fuel cells aren't hugely photogenic. Nonetheless, if a picture is worth a thousand words, this will be a long article.

Researchers from three continents have pushed the boundaries for direct ammonia fuel cells, setting records in power generation and continuous operation.

The maritime industry has begun assessing ammonia as a carbon-free fuel, for internal combustion engines and fuel cells. This marks the first time since the 1960s, when NASA used ammonia to fuel the X-15 rocket plane, that industry players have seriously considered ammonia for transport applications.
A paper has just been published by researchers in The Philippines who set out to determine the most environmentally benign way to produce, transport, and use ammonia as a fuel for vehicles.
This new work provides a detailed life cycle analysis of a broad range of ammonia technologies, evaluating both carbon and nitrogen footprints of each, and identifying the optimal "well-to-wheel" pathway. Their results support the idea that using ammonia for energy presents a safe and sustainable way to bring about the hydrogen economy.
Earlier this month the Eguchi Laboratory at Kyoto University announced advances in ammonia-fueled solid oxide fuel cell technology. The lab was able to produce a functioning fuel cell with a power output of one kilowatt. The device attained “direct current power generation efficiency” in excess of 50% and reached 1,000 hours of continuous operation.
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.
