Progress for Low-Temperature Direct Ammonia Fuel Cells
Article

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.

Our Iowa Renewable Hydrogen and Ammonia Generation System
Presentation

The presentation will summarize the development of the demonstration size renewable fuel and fertilizer system on my Iowa farm. Solar power, water, and air are used to make hydrogen and ammonia fuel used to power a modified John Deere 7810 tractor. The ammonia can also be used to fertilize corn cropland. The development of the ammonia reactor will be described and its performance discussed. There are no carbon emissions in either the generation or consumption of the hydrogen and ammonia.

Comprehensive Evaluation of NH3 Production and Utilization Options for Clean Energy Applications
Presentation

The project proposes a comprehensive investigation on the analysis, assessment and optimization of ammonia synthesis processes under renewable energy portfolio, including low-cost hydro, wind, solar, geothermal, ocean, biomass, etc. Furthermore, ammonia production via hydrocarbon decomposition, which will be investigated in the study, is a promising option to utilize fossil fuels in a cleaner and environmentally benign way. Case studies for various locations and applications in communities, cities and provinces to develop and implement clean solutions are performed. The objectives of this project include energy and exergy analyses, environmental impact assessments, thermo-economic analyses and evaluations, optimization studies, experimental investigation, scalability and…

Ammonia Renewable Energy Fuel Systems at Continental Scale
Presentation

We must soon “run the world on renewables” but cannot, and should not try to, accomplish this entirely with electricity transmission. New, abundant, low-cost, unconventional natural gas supplies are finite; burning adds CO2 to Earth’s atmosphere. Humanity’s goal must be nothing less than: Transforming the world’s largest industry from ~80% fossil to ~100% renewable, CO2-emission-free energy sources as quickly as we prudently and profitably can. We should now carefully consider using pipeline networks, rather than the electricity grid, for solving the three salient technical problems of renewable energy (RE) at lower cost: Transmission: from diverse, stranded, remote, rich RE resources…

Ammonia Fuel Safety
Presentation

This paper introduces the existing literature on the safety of using ammonia as a fuel, which provides comparative data for a range of traditional and alternative fuels and energy carriers. The studies reviewed conclude that risk levels associated with using ammonia as a fuel are “similar to those of gasoline,” or “similar, if not lower than for the other fuels,” also including hydrogen, methanol, LPG, and CNG. Ammonia as a fuel can meet all “acceptable” risk levels in even the most stringent regulatory jurisdictions. Addressing popular misconceptions and fears by providing robust sources for quantitative data on the dangers of…

NH3: The Optimal Alternative Fuel (2017)
Presentation

Unlike some technology areas where “all of the above” has significant advantages, there are tremendous advantages associated with choosing a single, optimized, liquid transportation fuel. The cost, efficiency and environmental benefits associated with choosing an optimized liquid transportation fuel are enormous and merit serious consideration. NH3 most closely meets the criteria for an ideal liquid transportation fuel. It is the most efficient and cost-effective means of delivering hydrogen and has an extensive world-wide delivery system already in place. Using currently available catalytic controls, NH3 emissions can be even cleaner than hydrogen engine emissions. While NH3 can effectively be produced using…

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

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.

China and Australia collaborate on ammonia as a clean transport fuel
Article

The University of Western Australia has entered the increasingly competitive field of ammonia energy research in Australia, announcing a collaborative agreement to develop "the world's first practical ammonia-powered vehicle" as well as an "ammonia-based hydrogen production plant." These goals are supported by funding from the R&D arm of Shenhua Group, formerly a coal company but now "China's largest hydrogen producer with a production capacity to power 40 million fuel cell passenger cars."

Optimizing technology pathways for Ammonia Fuel: production, transportation, and use
Article

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.
