Power to gas system
Urbánek, Štěpán ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
This bachelor thesis deals with Power to Gas system and its subcomponents. The first part of this thesis is research of the Power to Gas subcomponents. In the second part a balance model of the Power to Gas system is developed based on the traced technical parameters from the first part. The third part deals with traceable implementations of the Power to Gas system and the last part is the design of the system for home implementation.

Design of Energy Systems Using Hydrogen as Fuel
Slováček, Adam ; Bébar, Ladislav (referee) ; Houdková, Lucie (advisor)
Purpose of this thesis is wisdom accumulation from current area of energetic use of hydrogen and future systems. In overview is presented possible processes where dominate steam methane reforming. In main part of thesis, steam methane reforming will be analyzed and electrolysis also. Actual results will be discussed. Next part is about energetic use of hydrogen based on thermochemical properties and safety. Used of hydrogen will be divided to areas thermal generation as burner‘s section, electric generation as fuel cell‘s section, mechanical energy as combustion engine’s section and finally chemical transportation of energy. At the end will be made a promising energy systems using hydrogen as fuel which can be applied in a large scale.

Different use of the wind energy.
Sukup, Jan ; Houdková, Lucie (referee) ; Jícha, Jaroslav (advisor)
This thesis describe main kinds of wind turbines, principle of their functions and their usage to electricity generation. The second part deals with ways to storing wind energy. There is description of compressed air energy storage technology and their combination with combustion of biomass. Second mentioned energy storage technology is electrolysis of water and possibility of usage hydrogen.

Hydrogen production
Poláčik, Ján ; Fiedler, Jan (referee) ; Pospíšil, Jiří (advisor)
The thesis deals with water electrolysis focusing in particular on pulse electrolysis. The theoretical part characterizes hydrogen and its properties as well as the ways of its use and storage. It also analysis various methods of hydrogen generation. It examines in details water electrolysis and its energetic and chemical balance. There is also an evaluation of water electrolysis efficiency and its improvement followed by pulse electrolysis description. Laboratory equipment for direct current and pulsed direct current hydrogen production are suggested. Theoretical expectations are tested experimentally. Finally the thesis presents the results of measurements, compares and summarizes the data. It points out the contribution of this type of electrolysis with its effectiveness. It proposes uses of electrolysis and the subsequent research.

Sector coupling and the future form of the electricity and gas sectors
Švéda, Miroslav ; MA, Martin Šik, (referee) ; Radil, Lukáš (advisor)
This thesis deals with Sector coupling problematics. First, it deals with the development and present situation in the generation and consumption of electric power and the development and present situation in the extraction and consumption of natural gas in the Czech Republic and in the European union. Further, the thesis deals with Sector coupling, this concept is explained, and it is adumbrated what questions it deals with. Then, the technologies that can be achieved in the future of Sector coupling are introduced. Pilot projects of these technologies are presented as part of the discussion about these technologies. Finally, a consideration of the future use of Sector coupling technologies in the Czech Republic is given.

Storage of hydrogen produced by electrolysis in a metal hydride
Hamřík, Lukáš ; Libich, Jiří (referee) ; Novák, Vítězslav (advisor)
In the theoretical part, this thesis focuses on the possibilities of producing hydrogen from renewable and non-renewable sources, mentioning their advantages and disadvantages. The work describes the properties and basic principles of several types of electrolysis technologies. Technological options for hydrogen storage in the gaseous, liquid and solid phases are listed, in particular with a focus on hydrogen storage in metal hydride storage sites. In practical part, the hydrogen system that was the subject of the measurement is described. Block diagrams and a description of the realisation of control and measurement system engagement are provided, and the method of reading and writing data using LabVIEW is described. The resulting measured temperature and pressure dependencies of the metal hydride storage, their comparison with theoretical knowledge, as well as the two possible modes in which the assembled hydrogen system can be operated are described below.
