Using of CNG buses in Pilsen public transport

My bachelor thesis focuses on natural gas and its possible use in transport. The first part of the thesis is centred on physical and chemical properties of natural gas, its different forms (CNG and LNG) and advantages of it's use in transport. The second part of the thesis deals with the practical use of natural gas, specifically on the implementation of CNG buses into the public transport of Pilsen. Step by step, I have selected the most appropriate vehicles and filling stations. The outcome of the final calculation is that the implementation of CNG buses is much less costly than the using of diesel buses
