DECARBONIZING TRANSPORT: THE ROLE OF HYDROGEN FUEL CELL ELECTRIC VEHICLES IN REDUCING EMISSIONS
DECARBONIZING TRANSPORT: THE ROLE OF HYDROGEN FUEL CELL ELECTRIC VEHICLES IN REDUCING EMISSIONS

Summary/Abstract: Climate change, air pollution and noise, among other environmental problems, are increasingly affecting human society and the natural environment. Among the main sources of greenhouse gases and pollutant emissions in the atmosphere is the transport sector. To decrease the use of fossil fuels in the transportation sector, hydrogen fuel cell electric vehicles (HFCEVs) have been proposed as a potential alternative, among others. Although not completely green, from a life-cycle perspective, HFCEVs can have a lower climate impact than conventional vehicles, depending on how the hydrogen is produced. Widespread use of renewable energy sources can significantly reduce this impact. The research results show an increase in HFCEV sales recently (but far below the level of battery electric vehicles), concerns about the introduction of hydrogen in all transport sectors (road, rail, sea or air), still limited distribution of the infrastructure refuelling, and high production costs. HFCEVs could contribute to the decarbonization of transport and all efforts, including research and development, should be stepped up to support them and identify the best solutions to current challenges.
