Biogas technologies
Martanová, Iveta ; Jecha, David (referee) ; Beňo, Zdeněk (advisor)
This bachelor's work deals with technology of conception and production of biogas from biodegradable waste. In the introductory part there is elaboration of biogas facts, the principle of biogas origin and the usage of biogas in practice. The main part is dedicated to individual technology of the biogas production. There are descriptions of technological equipment for gas producing and descriptions of individual methods of waste processing indicating their advantages and disadvantages.

Biogas Plant Telč
Novák, František ; Hubáček,, Petr (referee) ; Myslín, Jiří (advisor) ; Skála, Jiří (advisor)
The biogas plant in Telč. Administrative and laboratory building is located on the premises of a biogas plant on the outskirts of Telč in the field of science and technology park. Half of a two-storey building will be used for laboratory tests which, under different operating conditions and settings will test changing input of crops, optimization of these parameters in different technological settings to maximize energy output. It will also be a place of management of biogas plant. The building is located in a slightly hilly terrain at an altitude of 539,350 meters and complies with disabled access.

Scientific technology park Telč
Musilová, Kateřina ; Suchánek,, Petr (referee) ; Nový, Alois (advisor) ; Donaťáková, Dagmar (advisor)
The subject of bachelor thesis is a design of a building of a Scientific Technology Park with laboratories for Energoklastr in Telč. Energoklastr is competency oriented cluster focusing on co-operation of small and medium size businesses, research organizations, universities and public sector in field of applied research and transfer of technologies. It significantly contributes to development of innovations, applied research and transfer of technologies in field of lowering energy demand. Energoklastr especially focuses its activity on technology lowering emission levels and sustainability of energetics in fields like a production of electric devices, aerial industry, car industry, IT and construction. Building site for meant for the construction of VTP with laboratories of effective use of biomass in energetics is to be found in cadastral area of Telč. It is located in north-west part of town, in neighborhood of existing industrial and agricultural buildings. The property is adjacent to a first class road number 23 (Třebíč – Jindřichův Hradec), that is one of the main connection to highway D1. VTP building with the laboratory is designed like a two story wooden structure with a flat roof and no cellar. The building is trapezoidal shaped, which is adjusted to a shape of the property. The building is divided to laboratory part and administrative part according to a story. There is a suspension stainless steel staircase designed in a lobby, which is discussed in part D – Architectonical detail.

Maize (Zea mays L.) cultivation for energy use
JIRAŇ, Michal
Maize is one of the world's among one of the most important crops. It is grown not only for food or feed but now increasingly used in industry. One of the possibilities of its use, which in recent years in the Czech Republic increased, the conversion of the biomass in the biogas into methane and other substances generated by anaerobic fermentation. Resulting gas mixture can be used for example to generate electricity through cogeneration units. The work is focused on the description of agricultural operations in the cultivation of maize sown. The work also describes the possibilities of using energy.

Proposal for measures to increase the efficiency of particular biogas station "Měčín" in the district Klatovy
MACH, Stanislav
The thesis is mainly aimed at agricultural biogas stations. The theoretical part is focused on agricultural biogas stations operation and the use of generated waste that is produced there. The practical part describes the economy, technology and the operation of the agricultural biogas stations Měčín. Further, the thesis suggests some measures to increase the efficiency by selecting appropriate substrates and especially the utilization of waste heat, which is not significantly used by the company.

Proposal for measures to increase the efficiency of biogas station "Agroplyn Mileč - Maňovice s.r.o."
TOMKOVÁ, Michala
The bachelor´s thesis deald in particular with distibution of heat produced in the biogas station in Mileč on Pilsen region. In addition, here describes the factors that affect efficiency of the biogas station, pre treatment of substrates, high quality technology, economic and technical part of heat distribution from a central supply of heat. Based on these findings can improve efficiency of the biogas station. Which will have a positive impact not only the environmnet but also on financial page of the biogas station Mileč.

Investment project evaluation: Construction of the biogas power plant Smržice
Kalista, Michal ; Kotáb, Jiří (advisor) ; Ropický, Jan (referee)
The investor has to decide whether he realizes the investment in the biogas power plant Smržice with a certain installed capacity If implemented, the investor is entitled to the government-guaranteed purchase price of electricity fixed for 15 years. It is necessary to predict profits and cash flows of each period which are further used for dynamic investment evaluation methods for the purpose of investment decision making. The application of the net present value shows whether the investment project is acceptable or not. The sensitivity analysis is used to compare changes in inputs with its impact on the net present value. The biogas power plant Smržice is typical example of biogas power plants built in Czech Republic in 2011-12 due to the government economic support, so finally these conclusions are generalised for the whole branch of electricity production from biogas.

Economic analysis of the project of a biogas power plant in the Czech Republic
Havlová, Kristýna ; Špička, Jindřich (advisor) ; Krause, Josef (referee)
In recent years, the society is more interested in the use of renewable source of energy, which is related to the establishment of biogas power plants. The aim of this thesis is to evaluate the economic benefits of investing in a particular project of biogas power plant where social impacts will not be the main indicator. In the methodological part is defined methodology (static and dynamic methods of investment decision making, sensitivity analysis). Followed by the introduction of the investor and the project. In the analytical part is evaluated the project from an economic point of view and ways of sales compared with use of biogas feed-in tariffs and green bonuses. The thesis also includes assessment of the impacts of investment from the economic, social and environmental point of view.
