Hydrogen for Power
Kocman, Lukáš ; Pospíšil, Jiří (referee) ; Skála, Zdeněk (advisor)
The increasing use of hydrogen in modern energy, has become the motive for writing this work. The work is focused on hydrogen energy and its aim was to compile an overview of hydrogen production technologies, the use of hydrogen technologies in current energetics and the use of hydrogen to energy accumulation. In addition to describing current hydrogen technologies, this work also includes examples of hydrogen devices and projects that we may encounter today. An overview of the above-mentioned technologies has shown that, despite some of its shortcomings, hydrogen has a significant application in current energetics, that is expected to increase in the coming years.

"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.

Steam-gas turbine for energy storage
Staněk, Štěpán ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
Master thesis discusses the growing need of electric energy storage and its effectivity and capacity. It describes an overview of possible technologies with their advantages and disadvantages. Greater attention is paid to the storage of energy in gas, so-called Power to Gas, which combines the electrolytic production of hydrogen from water and the Sabatier reaction to produce synthetic methane. This technology is introduced in the so-called SIT Brno cycle of Siemens Industrial Turbomachinery company. The main part of the thesis is focused on the description of this cycle and on the calculation of the steam-gas turbine (high-pressure and low pressure module). This thesis describes the methodology of turbine calculation and the composition of the steam gas mixture after combustion of methane. The carbon dioxide formed by combustion in the steam-gas mixture generator was replaced by steam. Part of the diploma thesis are drawings of cross-section of individual turbine modules.

Electricity storage with Power to gas
Bartlíková, Zuzana ; Pospíšil, Jiří (referee) ; Baláš, Marek (advisor)
This diploma thesis deals with accumulation of electricity energy using power to gas technology (P2G). The thesis is divided into two parts. The first part describes the whole system from the production of electricity, through water to the production of hydrogen by available technologies and possibilities of using hydrogen. For individual parts of the P2G system are described their operating conditions, advantages, disadvantages and efficiency. The second part of the thesis is practical. Several possible uses of hydrogen produced and the efficiency result of these P2G systems are determined. Finally, there is one use of the hydrogen produced which is compared from the energy point of view with the system that is currently used to store electricity.

Hydrogen as a promising energy carrier
Pinkas, Marek ; Brázdil, Marian (referee) ; Pospíšil, Jiří (advisor)
In recent years hydrogen has become an integral part of modern energetics. Although there are still many unresolved barriers and technological shortcomings in hydrogen energetics, its importance is expected to grow even more in the coming years. These facts were the motivation for writing this thesis. This bachelor thesis deals with hydrogen as a medium for energy storage and transmission as well as research about its properties, storage, production and use. In this thesis are described and compared various methods of long-term energy storage that are currently used. Presented are various traceable hydrogen pilot projects.

Power to gas
Copek, Tomáš ; Poláčik, Ján (referee) ; Pospíšil, Jiří (advisor)
This master’s thesis deals with Power to Gas technology. In this concept electrical energy is used for hydrogen production via electrolysis. Hydrogen can be injected in limited amount into natural gas grid, used for power generation via fuel cells or as a reactant for methanation process. Characteristics of hydrogen and ways of hydrogen production, storage and transport are described. Fuel cells are described as a device which uses hydrogen for power production. Crucial part of this thesis consists of a description of Power to Gas concept and a design of Power to Gas unit with electrical power of 9,5 kW. Three different units were designed for three different times of day operation. Efficiency and economical assessment was carried out for these three Power to Gas units.

Assessment of energy storage systems - Power to gas
Šojat, Filip ; Zlevorová, Tereza (referee) ; Baláš, Marek (advisor)
This bachelor's thesis is focuses on the issue of electrical energy storage using Power to Gas technology. The thesis is divided into two parts: a research part and a practical part. The research part provides a detailed description of the basic principles of Power to Gas technology, hydrogen production, and its potential applications in various fields. The practical part consists of a hypothetical study on obtaining electrical energy from solar panels and subsequently storing it as hydrogen. Various storage methods are compared.
