Small photovoltaic system
Just, Jan ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
This thesis describes the fotovoltaics at the present time. Introduction includes information regarding to resources of solar energy, main principle of transformation solar energy to electrical and history. Next parts summarise types of solar cells in economical term, types of material and description of their properties. Thesis includes the construction of fotovoltaic panel and its configuration to fotovoltaic systems with or without connection to electrical power network, contains convenient technologies for improving efficiency and the czech legislation. Final part focuses on designing grid-on system for real object including komplex study of object location, used components and calculation of whole produced electric energy and pay-back time. The main aims are presented in conclusion as well as advantages and disadvantages of the investment.

Biogas cogeneration
Miča, Martin ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
This bachelor´s thesis discusses biogas cogeneration. The introductory part deals with biogas production and its treatment before energetic use. The main body of the thesis focuses on various methods of energetic utilization of biogas and biogas processing in particular biogas station in Nové Město na Moravě. From the realised measurements there were created graphs of produced, sold and consumed electrical energy depending on days and average daily temperature. The last part of the thesis gives possibilities of waste heat recovery in wood dryer.

Separation and storage of CO2
Odložilík, Martin ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
The main objective of this work is to clarify the methods for CO2 capture and storage as an option to limit global warming. The first part is further explained by a phenomenon known as the greenhouse effect, there is illustrated his principle, the effects of climate change, the main factors increasing its intensity and its possible reduction. Framework of the second part is description of the technologies and methods of CO2 capture and storage, the individual steps in these processes and also the possible development in the future. Next chapter discusses the pilot research programs and application of referred technologies to in practice. The last part of this work is devoted to the economical aspect of the problems.
