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.
In recent months, research teams from both Canada and Italy have published comparative analyses of sustainable ammonia production pathways.
These projects aim to quantify the costs and benefits of combining Haber-Bosch with a renewable hydrogen feedstock. Both projects examine the carbon intensity of ammonia production but, while the Canadian study broadens its remit to a full life cycle analysis, including global warming potential, human toxicity, and abiotic depletion, the Italian study focuses primarily on energy efficiency.
Ammonia energy proponents look forward to the day when their fuel is used in internal combustion engines – but the state of this art is unsettled and it is not clear which combustion technologies will win in the end.
A recent paper from the University of Ontario Institute of Technology, published in June 2016, provides new data on the relative efficiency and safety of using ammonia as a transportation fuel. It presents a cradle-to-grave "comparative life cycle assessment" for a range of vehicles, encompassing the vehicle cycles (manufacturing, maintenance, and disposal) and the fuel cycle (operation).
