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.
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.
Eddie Sturman, noted inventor and co-founder of Sturman Industries, has been developing ammonia internal-combustion-engine (ICE) technology for several years – "at least six, maybe more." At the 2016 NH3 Fuel Conference, he provided the most in-depth look so far at the results of Sturman Industries' R&D program. Specifically, his talk featured a dual-fuel compression ignition engine powered by a combination of diesel fuel and ammonia.
