Abstract

The problematics of decarbonisation in road transport sector is considered in this chapter. The impact of growing motor vehicle fleet on pollutant by carbon dioxide (CO2) gases of atmosphere is analysed. The detail analysis of purposeful restriction of permissible level of comparative amount CO2 in car exhaust gases in EU to control the total CO2 emission in road transport sector is presented. The urgent demand to use carbonless fuel additives to stop the growth of total amount of CO2 emission during vehicle traction transient process “from heat power to electric power” is clarified. The introduction of electric cars by itself does not solve the problem of decarbonisation, since it is necessary to assess how electricity is produced, whether from renewable sources or by burning fossil fuel. The objective reasons for the delay in the widespread implementation of electric vehicles are investigated: the distance of one battery charge dissatisfied with drivers, an underdeveloped network of battery recharging stations, problems with the capacity and overloads of state-run electric networks, aspects of determination of time for recharging private cars, and insufficient government support measures. The main characteristics of the integrity of biofuel production and use and the continuous biofuel supply chain are described. Direct and indirect the 4th generation biofuel production processes, photo-fermentation and gaseous reversible reaction for hydrogen production are described. Using of hydrogen as carbonless fuel for internal combustion engines (ICE) slightly improves the burning processes of ICE combustible mixture and this decreases on ICE emission harmfulness. The undisputed advantages of hydrogen as ICE fuel additive encourages the development of hydrogen re-fulling infrastructure. Gained results of performed stand tests to define the efficiency of ICE and exhaust gases toxicity using Brown’s gas (HHO) are described. Finally, basic conclusions are given.
