The role of hydrogen for future internal combustion engines

Considering the trend of mitigating climate change worldwide, the contribution of a widespread, reliable and affordable propulsion technology like the internal combustion (IC) engine can be significant, once a renewable fuel is used as replacement of typical fossil fuels. Hydrogen and hydrogen-dense liquid fuels can play a relevant role in this sense, allowing zero CO₂ emissions and zero-impact pollutant emissions from IC engine powertrains. The main issues are related to the availability and production of H₂ and its safe storage at the point of use. These factors involve economic considerations that must be balanced against the costs to society, associated with the potential reduction of carbon emissions from existing hydrocarbon fuels. The H₂ fuelled IC engine is a viable alternative to rely on the thermal powertrain without producing any tank-to-wheel CO₂ emissions at the tailpipe. Moreover, H₂ICEs can be fuelled with non-purified hydrogen, resulting in significantly lower production cost of hydrogen fuel. High boost pressures, direct injection, advanced combustion modes, deployment of laser ignition, and dedicated after-treatment SCR systems will guarantee a competitive, high efficiency propulsion technology.
