Energy balance of biomass heating plant
Žmolík, Václav ; Šen, Hugo (referee) ; Baláš, Marek (advisor)
This thesis deals with a design of a biomass heating plant combinating a Rankin-Clausius cyklus and a CHP unit. The CHP unit fuel is a biogas and the boiler fuel is a wooden chip. The adapted CHP unit regenerates feed-water of the R-C cycles. This design is technicaly and economicalty compared with the Rankin-Clausius cycle without feed-water regeneration by the CHP unit.

UTILIZATION OF BIOGAS IN TRANSPORT
Štylárek, Milan ; Zháňal, Lubor (referee) ; Vopařil, Jan (advisor)
Objective of this bachelor thesis is evaluating the possibility of utilization of biogas as an alternative fuel for combustion engines in traffic. Production and distribution of upgraded biogas is described as well as situation of its utilization in the world. This is followed by a comparison of situation in biomethan utilization in Czech republic and Sweden. There are explained barriers to commercial placing and its possible eliminating. In the end the model study of replacement of farm vehicle fleet for CNG vehicles is described.

Natural gas
Trávníček, Zdeněk ; Moskalík, Jiří (referee) ; Pospíšil, Jiří (advisor)
The aim of the bachelor thesis is to collect facts about natural gas, focusing mainly on the situation in the Czech Republic. Firstly, the thesis discusses the natural gas in general - its properties, world resources, ways of production and usage. The main part of the thesis deals with supply and accumulation of natural gas in the Czech Republic. Secondly, enumeration and brief description of possibilities of natural gas substitution is presented. Finally, comparison of usage of classic non-condensing and condensing boiler for a family house heating is introduced. Recommendation of boiler type based on the model example is included as well.

Modern Biogas Station as Part of "Smart Regions"
Horák, Jakub ; Pavel,, Milčák (referee) ; Lisý, Martin (advisor)
This thesis deals with the design of computational model of a biogas plant and its use in the concept of intelligent region with focusing on district heating and cooling network. The introduction contains review of technology used in the biogas plant. This review covers the description of modern biogas plants and determination of the energy and technology parameters for computational model of biogas plant. The next part of thesis describes analyze of the dynamics of the operation and the possibilities of using waste heat from biogas plant. The last and also the most important part is based on design of computational model of a biogas plant and design of connection of a biogas plant to the district heating and cooling network.

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.

Biogas cleaning to substitute natural gas quality
Němec, Jan ; Niesner, Jakub (referee) ; Dvořák, Radek (advisor)
This work deals with methods of biogas cleaning to natural gas quality for further use. The introduction is focused on technologies for biogas treatment and biogas management for current situation in the Czech Republic. In the main chapter there is a water scrubber technology design and calculation of the absorption column for the conditions given. A simulation model and preliminary economic balance were then developed on the obtained data.

Utilization renewable energy sources inside of EPS Czech Republik
Zmeškal, Pavel ; Procházka, Zdeněk (referee) ; Matoušek, Antonín (advisor)
The purpose of this work was the analysis of current state and further development of renewable energy in the Czech Republic. And next their effects on the electricity system of the Czech Republic. On the basis of established facts has been developed actual state of renewable energy sources. The current situation is only orientation and is still changing at this time. Another objective was to evaluate the various renewable energy sources in terms of their impact on the electricity system and recoverability in the Czech Republic. In more detail were read up the conditions for the wind power plants operation and their connection to the electricity system of Czech Republic. In fine were discuss the impact of renewable energy sources on electricity system and prerequisite for their further development in the Czech Republic.
