Risk analysis of energy storage
Albert, Tomáš ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
This bachelor thesis analyzes the risk of accumulation of electrical energy and problems with its storage. The first part describes the various storage systems of electricity and are given their advantages and disadvantages. In the second part systems are compared against each other. The final section is intended suitability of each system and its use for application in the vicinity of Brno.

Kinetic energy recuperation systems
Hapala, Miroslav ; Porteš, Petr (referee) ; Zháňal, Lubor (advisor)
This bachelor thesis deals with kinetic energy recuperation systems (KERS), which is obtained by braking, in cars and sports cars. In the first section describes the different types of systems, their function and the accumulation of energy. In the second part are some examples of use in passenger transport and in motor racing. In the conclusion are summarized their advantages and disadvantages and their contribution to the future ecology of automotive traffic.

Hydrogen and automobiles
Břoušek, Lukáš ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
The purpose of this thesis is to demonstrate the possibilities of hydrogen-based gear in personal cars. The thesis also describes the hydrogen from the perspective of the characteristics, the form of production, conserving, distributing and its utilization. Furthermore, in more details are described and compared currently well-known hydrogen-based devices, for this purpose the complex analysis Well to Wheel will be used. Final part of this publication will be devoted to evaluation of this analysis and also the thesis will outline what are the probable trends of the hydrogen-based technologies.

Hydrogen fuels
Umlauf, Martin ; Bébar, Ladislav (referee) ; Jícha, Jaroslav (advisor)
Paper presents a basic review and comparison of energy-conservation made of renewable sources. Principal question of paper concerns evaluation of hydrogen-use made of electrolysis of water. First part of the thesis focuses on the production of energy from renewable sources and the possibility of energy-accumulation. The next section describes methods of hydrogen production and utilization of hydrogen as a fuel for combustion engines. Attention is paid to various aspects dealing with construction of combustion engines using hydrogen. Final part of the study presents comparison between combustion engines using known sorts of fuels as to their pollution and emission-level. Next comparison deals with economic cost per kilometer, when different sort of fuels are taken into account. Conclusion concerns approximate calculation of the production of hydrogen from water by electrolysis using photovoltaic power plants.

Possibilities of energy storage
Sedlák, Petr ; Hrnčířová, Michaela (referee) ; Moskalík, Jiří (advisor)
Because part of energy produced from renewable sources is growing continuously, increasing the gap between consumption and production of electricity. This has a negative impact on the electricity grid, therefore hence the need to accumulate energy. In the following work is mapped out different ways of accumulation of electrical energy. There is described their used, advantages and disadvantages of different storage systems

Systems energy recovery for personal and sports vehicles
Marada, Ondřej ; Zháňal, Lubor (referee) ; Beran, Martin (advisor)
This bachelor thesis is dealing with methods to decrease energetic and ecological load of cars. In particular, it follows kinetic energy recovery systems (KERS). The thesis summarizes the types of KERS, their building elements, i. e. the establishment for accumulation of energy and its transmission. Then the survey of known fulfilments KERS follows and in the conclusion it is dealing with their contribution to the use of sport and personal motor cars.

Utilizing of wind energy with accumulation
Mészáros, Gabriel ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
The introduction of this paper deals with wind-powerplants, their components and distribution according to their construction and output. Technologies of accumulation of energy are described, because the conditions for energy production from wind are not constant (windlessness, storms, etc.). The technologies are compared in terms of economics and technology. A basic design for a system with accumulation is made at the end of the thesis.

Solar charge controllers for off-grid systems
KRČKA, Pavel
This diploma thesis deals with photovoltaic rechargable regulators used in isolated, or off-grid photovoltaic systems. First, basic types of off-grid installations, including their functions and applications in practice are described. Then, possibilities of electric energy accumulation in photovoltaic systems are mentioned, considering actual, accesible technologies. Matters of electric energy accumulation in leaden accumulators are examined in detail. Main part of the diploma thesis is about electronic designs of photovoltaic, also called solar, rechargable regulators. These are the main connecting part between photovoltaic panels, accumulator, but also often connected charge, which is appliance. Individual electronic regulators concepts are described narrowly, then compared and evaluated in thesis´ conclusion.
