Abstract: The report presents the main results of an experimental campaign carried out by the JRC in the support of the legislative activities on type approval of hydrogen-powered motor vehicles. It serves as the scientific and technical basis to test the proposed methods for type approval regarding vehicles using a variable mixture of H2 and Compressed Natural Gas (CNG). A prototype bi-fuel vehicle is tested, designed to operate either on petrol or on various H2-CNG blends, with maximum percentage of 30% H2 on CNG. The methodology used to estimate the unburned hydrocarbon’s density, the fuel density, the fuel consumption, and the heating value of each H2-CNG blend in presented. The bag and modal gaseous emissions, as well as the particulate emission performances of the vehicle tested under the various H2-CNG blends and on petrol fuel is presented. It can be concluded that the use of such fuel mixtures can provide a positive input to the reduction of pollutant emissions as well as of greenhouse gas emissions.
