Hydrogen production from renewable sources
Balko, Michal ; Kropáč, Jiří (referee) ; Houdková, Lucie (advisor)
The goal of this bachelor's thesis is to make a summary of actual hydrogen production possibilities both from fossil fuels and from renewable sources. First part deals with production by steam reforming of natural gas and water electrolysis. Next comes the production from biomass by photofermentation and fermentation. Attention is paid especially to input materials and process conditions. In the end chosen processes of production are compared by their energy intensity found out by simplified calculation.

Sewage sludge drying - theory and practice
Sirový, Martin ; Elsässer, Thomas (referee) ; Houdková, Lucie (advisor)
The thesis deals with sludge drying coming from biological sewage disposal plants from theoretical and practical points of view. The first chapter deals with the sewage disposal plant functioning and with sludge formation there. Furthermore sorts and properties of water treatment sludge are described here. In the second chapter the thesis points the look to the industry drying theory and then to the theory of sludge drying. The third chapter contains a list of current drying chambers convenient for sludge drying and their principles and description. The fourth chapter points to the present practice of sludge drying in the Czech republic. Prospects of the water treatment sludge drying are evaluated in the concluding part.

Production of biogas as an automotive fuel from renewable materials
Frühbauer, Zdeněk ; Houdková, Lucie (referee) ; Dlabaja, Tomáš (advisor)
The aim of this thesis is to specify and summarize possibilities of biogas production as a motor vehicle fuel by using the renewable energy sources. In the first part of the thesis there are the data concerning biogas, its production and chemical composition. An important part of the thesis is a description of current most used methods of cleaning which adjust biogas to quality of natural gas. The important part of this thesis is to introduce some of already working projects and to get knowledge about possibilities of making biogas from biologically decomposable material as a renewable energy source. The close of the thesis deals with energy, economy and ecological audit too and values biogas through all angles which decide about its using in larger size in the car industry.
