Description

Road traffic is one of the transportation sectors with faster growth due to the of vehicle fleets increase and a strong investment in road infrastructure and also one of the most important emitters of greenhouse gases (GHGs).With introduction, in this sector, of a new renewable fuel, like hydrogen, a reduction of the reported pollutant is foreseen. In this work, an analysis of the environmental benefits resulting from the introduction of hydrogen on road transport in Portugal is made. Impact is analyzed mainly looking at the pollutant emissions provided by road transport at the point of use. The software chosen to calculate the emissions associated to road transport is the COPERT program (version IV) since it provides a detailed methodology for each specific pollutant related to the vehicle fleet of a region or country, as well as the driving conditions and fuel consumption.
