Renewable energy sources in CR
Luermann, Július ; Moskalík, Jiří (referee) ; Fiedler, Jan (advisor)
The bachelor’s thesis deals with potential and utilization of renewable energy sources in Slovakia, including description of technologies using these energy sources in the first part. It is written about biomass as a renewable source of energy, methods of biomass processing and its utilization possibilities for producing electricity and heat energy in the second part. The last part of the bachelor’s thesis concerns with technical characteristics of technology using biomass – specifically with Biogas station in Chynorany near Partizánske.

The application of different types of substrate in the biogas plant
SIKYTOVÁ, Pavlína
Support and investment´s subsidies of production of electricity from renewable sources after 2009 made a phenomenon from a biogas plants. This thesis specifies the most used feedstock for biogas production in the Czech Republic. Each substrate used in biogas plants, have different chemical composition, dry matter content, thus providing another volume of biogas. Specifications of elections of substrate, was made on the based on consultations with the operators of agricultural biogas plants. Stabilized anaerobic process increases the production of biogas and supports economic situation of farms.

select suggestions for increasing the efficiency of biogas plant in Koloměřice.
ČERVENKA, Pavel
In my bachelor thesis I will try to introduce the topic of importance and operation of biogas plants. The theoretical part focuses on the entire operation of biogas plants, types of biogas plants, the inputs and outputs and processes. The goal of the practical part was to describe the biogas plant in Koloměřice, make out the processing of by-products and select suggestions for increasing the efficiency of biogas plant in Koloměřice.

BIOMASS AS RAW MATERIAL FOR THE PRODUCTION OF FUELS AND ENERGY
SIKYTOVÁ, Pavlína
The aim of this research is to develop technological processes for energy recovery, with an emphasis on biomass power generation and the production of biofuels. The work describes and shows the types of biomass, possibilities of its use and development phase of processing of biomass. The prospect of biofuel use i mentioned and in the end the topic is elaborated on the legislative environment and promotion of biomass in the Czech Republic.

The apply digestate at operate of biogas plant agricultural type
ČÁPOVÁ, Aneta
Comparing inputs needed to operate biogas stations, this Bachelor paper focuses on the composition of digestate and on its use in five examined stations. The paper is split into two sections: theoretical and practical. The theoretical section, i.e. a summary of relevant literature, explains the basic concepts and other issues related to the biogas proper, biogas generating stations, substrates and digestates. The practical section deals with experimental data obtained from the five stations. The data were acquired through a questionnaire wherein the stations' operators described their facilities while specifying the parameters; substrates applied; methane yield figures; results of digestate analyses; and their methods of application.

Green technologies and their use in the Czech Republic
MRKVIČKOVÁ, Markéta
This Bachelor thesis on the topic of Green technologies and their use in the Czech Republic is focused on the area of renewable energy sources. Overall, it clarifies the issue of waste, to use them, and assesses the technologies implemented in the South Bohemia region, that ensure they are processed from ekononomical and ekological point of view. Processing of this Bachelor thesis is focused not only on mapping out of the current state but even on prediction of potential future development in the closing chapters of the text.

Production and usage of biogass in South Bohemia
KALINOVÁ, Lenka
The bachelor's thesis deals in particular with comparison of biogas production in individual biogas stations in the South Bohemian Region. In addition, the thesis describes fundamental parameters such as year of commissioning, installed electric output, installed thermal output, input material and employed technologies. Based on the foregoing information, it is possible to conclude that the individual biogas stations have a positive impact not only on the utilization of the produced biogas for energy purposes but also on the environment, waste degradation, reduction of the risk of contamination and acquisition of high-quality fertilizer.

Using of digestate of agricultural biogas stations
VERNER, Dušan
This work deals with problems of agricultural biogas stations with the focus on using of final product of anaerobic fermentation, digestate, on agricultural soil. It evaluates its fertilizing effect in comparison to industrial fertilizers. The results showed that the fertilizing effect can improve economy of growing plants, however it depends on quality of digestate, constitution of base input material and technology of processing. It is not possible to use digestate anytime, it depends on growing crops and its technology. Nevertheless digestate as a final product of anaerobic fermentation is an interesting fertilizer.

Utilization of Zea mays L. for energetic effects
RATAJ, David
This bachelor thesis deals with the types of energy use of flint corn (Zea mays). It compares the suitability of hybrid maize lines. The thesis is to summarize and compare the literature data on other types of energy crops and compares them suitable for cultivation for energy recovery on the basis of some production capacity and energy parameters (dry matter yield, energy recovery, combustion heat and humidity).
