Storage systems for renewable energy
Švácha, Filip ; Kracík, Petr (referee) ; Poláčik, Ján (advisor)
The aim of the thesis is to describe the current possibilities of storing electricity from renewable sources focusing on hydrogen technologies. In the first three parts, the question of energy sto-rage from renewable sources, the current energy storage options and the actual energy storage in hydrogen are discussed in the form of research. The last part is practical and its aim is to compare the current possibilities in designing a system that stores energy in hydrogen. Subsequently, the most favorable option is chosen and compared to other energy storage methods.

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.

Conventional and unconventional energy storage technologies
Mikulec, Ondřej ; Rujbrová, Šárka (referee) ; Jašková, Jana (advisor)
Tato bakalářská práce se zaměřuje na systémy používané pro skladování elektrické energie od již integrovaných konvenčních metod až po nekonvenční. Tato práce podává základní výklad těchto systémů a jejich začlenění do elektrické sítě. V další části práce se zaměřuje na jejich výhody a nevýhody z různých pohledů. Poslední část práce věnuje velkou pozornost přímému srovnání daných metod, aby dále nastínila jejich hlavní slabiny a zároveň ukázala jejich silné stránky, díky kterým jsou vhodnější pro další rozvoj a budoucí integraci.
