In an ever-evolving energy landscape, directed more and more towards sustainability, the reduction of pollutant emissions and the development of alternative technologies for both land propulsion and energy generation for stationary applications, the following work is meant to be placed: in this sense, hydrogen has always been highly interesting from a technological point of view, especially when used in the context of internal combustion engines, taking advantage of the knowledge and know-how obtained in the development of classic gasoline engines. However, the use of a fuel that has physical-chemical properties that differ from those of conventional fuels poses new problems and challenges.
