Alternative fuels for transport
Běláčková, Adéla ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
The thesis Alternative fuels for transport is dealing with the topic of economic competitiveness and environmental advantages of alternative fuels in comparison to classical oil fuels in transport. First, the main transport related problems are discussed in detail, including the dependency on oil, emissions from transport and their impact on human health and the environment. Then, the different types of alternative fuels are presented, including the legal framework, possibility of tax exemption and subsidy financing. The comparison of emissions of alternative and classical fuels follows the logic of the whole life cycle of a fuel, using the Well-to-Wheel analysis as method. Emissions of greenhouse gases and emissions of pollutants of local importance are observed. The cost comparison is based on experience in public bus transport in the Czech Republic. Fixed, variable and total costs are compared for classical diesel, biodiesel, natural gas, LPG, hydrogen and an electric vehicle. The purpose of the study is to decide which of the alternative fuels represents a cost competitive option in comparison to classical diesel and also provides a reduction in total emissions. The results of the study are designed to help Krkonošské Metro Association to choose a suitable alternative fuel for a project in rail transport.
