Alternative use of biomass
Hornoch, Radek ; Radil, Lukáš (referee) ; Bartošík, Tomáš (advisor)
This bachelor´s thesis describes the options of the processing biomass on the nobler fuels and their using. In the first part are described the sources of biomass so the option targeted grow crops or use different convenient wastes. The second part contains a description of the technology, how to revise the biomass to synthesis gas, methanol, ethanol, biodiesel and biogas. They are given yields on already mentioned high-grade fuels from individual crops and technologies. The third part deals with device where it is maybe to use nobler forms of fuels. It is going about traditional heating plant with back pressure or condensing extraction turbine, steam heating plant, a cogeneration unit with micro turbine, a cogeneration unit with combustion engine and a cogeneration unit with fuel cells. At the end of the chapter is a comparison of the different devices when using different fuels.

Nonconventional Utilisation of Wind Energy
Zajíc, Josef ; Turek, Vojtěch (referee) ; Jícha, Jaroslav (advisor)
The thesis considers utilization of the wind energy as source of energy for the production of hydrogen. In the first part, there is described the types of wind engine specialized especially on screw wind engines and their construction. After that follows the description of dilemmas usage of electric energy addicted in time and with it connected problems with accumulation elektricity by the help of various methods. The final part of the thesis is than addicted to statistic evaluation of wind conditions, description and suggestion of the equipment hydrogen management.

Energy efficiency of hydrogen utilization in transport
Mikulenka, Karel ; Kučera, Pavel (referee) ; Vopařil, Jan (advisor)
This bachelor thesis analyses current possibilities of hydrogen usage in transport. Hydrogen is by scientific community viewed as a possible answer to ever growing emissions from transport and their negative affect on the environment. The work introduces the most significant advantages of hydrogen usage as a fuel in comparison to its counterpart combustion engine and battery vehicles. Two means of obtaining energy from hydrogen in a vehicle itself shall be described which are hydrogen combustion and fuel cells. Further shall be made analysis of current possibilities for potential end customer pertaining vehicle and fuel availability. In the end is given a general description of hydrogen transport implementation in Czech Republic and its energetic cost and efficiency within an overall hydrogen economy.
