Comparative studies of ammonia production, combining renewable hydrogen with Haber-Bosch
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 Fuel Cells: SOFC stack test and system analysis
New research, recently published in the International Journal of Hydrogen Energy, demonstrates that solid oxide fuel cell (SOFC) systems fueled with ammonia could be "more efficient than equivalent hydrogen-based" systems. This new paper comes out of the Fuel Cell Lab at the University of Perugia, in Italy, and builds upon years of research coming out of that laboratory on the use of ammonia and urea in fuel cells.

Further Evolution of an Ammonia Fuelled Range Extender for Hybrid Vehicles
In a previous research the possibility to run a small 4-stroke twin-cylinder SI engine of 505 cm3 with ammonia plus hydrogen was demonstrated. Ammonia and hydrogen tanks were utilized to feed the engine while, apart, the suitability of a custom-designed catalytic reactor to produce hydrogen from ammonia with the required flow rate was verified as well. The experimental activity confirmed the need to increase combustion velocity by adding hydrogen to air-ammonia mixture, with energy ratios that mainly depend on load and less on engine speed. The minimum hydrogen to ammonia energy ratio was found below 6% at full load and…

A Hybrid Vehicle Powered by Hydrogen and Ammonia
A partnership of Research and Industry entities has developed a fully working hybrid electric vehicle equipped with a 15 kW IC engine fuelled with liquid ammonia as a range extender of the lithium batteries pack on board. The entire vehicle powertrain (ie, the IC engine, the electric generator coupled with the engine, the electric motor, the electronics etc.) has been studied and designed. Regarding the IC engine, as is known, ammonia combustion is characterized by a high activation energy and a low flame velocity, therefore a small amount of hydrogen is requested as igniter and combustion promoter. The necessary amount…
