Perspective trends in hydrogen production methods
Leitkep, Jan ; Juřena, Tomáš (referee) ; Brummer, Vladimír (advisor)
Bachelor’s thesis is focused on perspective methods of hydrogen production. First chapters are focused on research of hydrogen resources, methods of hydrogen production and spectrum of its worldwide utilization in present. In this part of the bachelor’s thesis percentage representations of hydrogen resources are stated. Methods of hydrogen production from these resources are described and processes utilizing hydrogen are introduced. Subsequently, the properties of hydrogen fuel are summarized. Following chapters are focused on perspective methods of hydrogen production, hydrogen storage, perspectives of its future usage as a fuel, price of hydrogen produced by these methods and environmental impact of these methods.

Leakage measurement for hydrogen gases
Spáčil, Petr ; Brázdil, Marian (referee) ; Šnajdárek, Ladislav (advisor)
This master's thesis deals with the measurement of hydrogen gas leaks and addresses key aspects related to hydrogen properties, storage, use, safety aspects, detection methods and seal testing. The study highlights the importance of safety in handling hydrogen and includes a thorough analysis of its properties. It discusses different methods of measuring hydrogen concentration and detecting leaks and assesses the suitability of different gasket materials such as polyester, elastomer, steel and graphite for use with hydrogen. Furthermore, the thesis presents experimental investigations into leakage testing. The findings of the study assist in the selection of the right gaskets and improve understanding of leak measurement techniques, which in turn improves the safety and efficiency of hydrogen applications.
