Energy use of waste
Přidal, Milan ; Špiláček, Michal (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with waste-to-energy topic. The first part is focused on basic informations about waste. Specifically about production, distribution and hieararchy of waste management. The following section describes composition and properties of municipal waste as a fuel. This part also evotes some technologies which are used in facilities for the energy use of waste. Third and fourth chapter shows and compares particular waste-to-energy plants in Czech republic and rest of the world. The goal of final part is to warn about some ecological aspects and try to create their objective view.

Alternative Energy Resources for Family House
Němec, David ; Brázdil, Marian (referee) ; Špiláček, Michal (advisor)
This bachelor thesis is focused at an issue of thermal energy supply for family houses from renewable resources. The aim of this thesis is to provide a summary of possible thermal energy supplies from renewable resources (solar collectors, heat pumps). After that follows a draft and economic evaluation of these systems for individual sources of thermal energy. In introductory section a solar energy is described. It is a significant part of renewable energy. This part is followed by review with description, composition and principle of individual types of solar collectors and heat pumps. Next part is focused on draft of these systems. Conclusion is then dedicated to energy evaluation of individual designed systems.

"Power-to-Gas" Energy Storage Technology
Gálíček, Radomír ; Špiláček, Michal (referee) ; Poláčik, Ján (advisor)
Climate change is becoming a severe global issue which demands innovative technical solutions. If, in the context of reduction of gaseous carbon emissions, the share of renewable energy resources continued to rise, the need for energy storage would emerge. That could mean a shift towards hydrogen focused technologies. This bachelor’s thesis focuses on Power to gas processes and summarizes means of hydrogen production, storage and transportation. All the mentioned aspects are reviewed from technological and economical point of view. Conventional methods of hydrogen production from fossil fuels are the most common, but usage of electrolysis or biological methods may prove as competitive options in near future. Furthermore, the usage of fuel cells in the field of small-scale cogeneration units is recently going through a phase of dynamic development. The practical part of this thesis focuses on designing a seasonal Power to gas unit for a semi-detached house which is powered exclusively by renewable resources. From numerous variants the best one was chosen and compared to a conventional energy storage using lithium batteries. It is shown that even thou the electrochemical cells are more flexible variant they couldn’t match Power to gas technology in the term of seasonal energy storage.
