Reduction of CO2 Emissions for the Mobility Sector in View of 2030

About this Research Topic

Recently, the interest towards sustainability and emission reduction is progressively increasing. The decarbonization of all the energy intensive sectors is a common target. The augmented incidence of renewable energies has altered the usual paradigm of energy generation. Similarly to power generation sector, also the mobility sector is experiencing a renovation. Increasing interest is being paid towards those technologies that guarantee a reduction of carbon dioxide emissions. Internal combustion engines were for decades an undiscussed player in the mobility sector. Years of research and development brought these engines to unpaired efficiencies and performance. On the other hand, their environmental impact is still an issue especially in view of a defossilization of the mobility sector. In this aspect there is a strong need for introduction of renewable fuels, which efficiently tackle issues related to GHG emissions, while, although featuring low concentrations, emissions of toxic species are not fully eliminated.

The mobility sector is now facing new challenges to reduce emissions and environmental impact. Many solutions are potentially viable to this purpose, each one with advantages and drawbacks. There seems to be a common consensus that in the mid future, a single solution will not be suitable for all the applications. Undoubtfully, electric mobility is advancing fast, but still some concerns exist for application in trucks and long distance travelling, where fuel cell powered vehicles appear as a viable emission free solution. Other sectors, as the marine one, where internal combustion engines are widely used, might impose more challenges during transition, whereas also in this section battery electric powertrains and fuel cell powertrains are emerging as viable solutions in specific applications. In this transition period other solutions might also be viable and interesting. In this sense, hybrid solutions seem very appealing as well as the adoption of low carbon emission fuels with emphasis on the renewable ones (e.g. Hydrogen, bio-fuels, NG…) or the improvement of performance (e.g. new cycles or energy recovery from exhaust gasses).

This Research Topic would like to encourage original contributions regarding recent developments and concepts related to the reduction of the carbon dioxide emissions in the mobility sector. Potential topics include but are not limited to:

• Hybrid systems,
• Use of renewable fuels,
• Hydrogen based systems including fuel cells,
• New engine concepts,
• Improvement of engine performance,
• Reduction of specific emissions,
• Use of wide range of energy storage systems,
• Energy recovery systems,
• Improvement of cycle efficiency.


Keywords: CO2 Emissions, Fuel Cell Powered Vehicles, Hybrid solutions, Engines Efficiency and Performance, Mobility Sector
