Weaknesses of hydrogen energy
Zeleňák, Rastislav ; Elbl, Patrik (referee) ; Baláš, Marek (advisor)
This Bachelor's thesis focuses on exploring and researching the various technologies available for producing hydrogen and their shortcomings. The production of hydrogen, a clean and renewable energy source, has become increasingly important as the world shifts towards sustainable energy solutions. This thesis examines the various methods of hydrogen production including steam methane reforming, electrolysis and production by biological processes. This bachelor's thesis also deals with different methods of storing hydrogen and transporting it. Next, the negative properties of hydrogen are listed, such as its explosiveness, or the degradation of materials used in hydrogen technologies, i.e. hydrogen embrittlement. The work focuses on its characterization, mechanisms and prevention against it.
Economic Return on Measures for the Greening of House Heating
Zubek, Tomáš ; Elbl, Patrik (referee) ; Lisý, Martin (advisor)
High and constantly changing energy prices lead us to effort for efficient solutions in the energy aspect of houses. Suitable measures need to be taken to ensure the efficiency of heating in a family house. This work deals with measures to reduce heat losses and the choice of heating sources. Through the right combination, it is possible to reduce the energy demand of a family house and ensure environmentally friendly and cost-effective operation. In the final part of the thesis, individual measures are proposed and evaluated on a model family house. The calculation is performed using the energy calculation program Energie 2023. The main outcome is the financial return of individual measures and their comparison. At the end, the combination of these measures is considered along eith its economic evaluation.
Hydrogen production and storage
Tunys, Daniel ; Lachman, Jakub (referee) ; Elbl, Patrik (advisor)
The submitted bachelor’s thesis deals with the research od available methods of hydrogen production and storage and a summary of important current or future hydrogen projects. The thesis discusses possible ways of hydrogen production from fossil and renewable sources and puts into perspective the advantages and disadvantages of individual conventional and experimental methods. The described methods are also compared in terms of emissions that arise during the process. Furthermore, the thesis compares different methods of hydrogen storage and transport with regard to the appropriate practical use of each of them and describes the advantages and disadvantages of different hydrogen storing methods. The last part is an extract of important Czech and global hydrogen projects and hydrogen strategies of individual countries.
Design of systems reducing the energy dependency of an apartment building
Cetkovský, Vojtěch ; Elbl, Patrik (referee) ; Toman, Filip (advisor)
This work deals with the issue of reducing energetic efficiency of the apartment building. The aim of this work is a comparsion of individual variants of systems that reduce energetic efficiency of an apartment building. This problem is approached in three steps. In the first part of this bachelor’s thesis, the theoretical background was elaborated with the help of literature search, which consisted of academic articles and academic literature. In the second part, a calculation on total supplied energy delivered into the building was made, and then the individual variants were compared with each other. The last part of the work was devoted to the economic valorization of individual variants and a selection of the most appropriate variant from the point of view of an annual operating costs of the building and the return on investments.
Thermonuclear fusion for power generation
Osolsobě, Jiří ; Elbl, Patrik (referee) ; Sitek, Tomáš (advisor)
Controlled thermonuclear fusion opens up the possibility of using similar principles that take place in stars to produce energy on planet Earth. A fusion power plant would represent a stable, safe, emission-free and, for the foreseeable future, inexhaustible source of energy. Currently, the most researched fusion device is a tokamak using magnetic confinement of plasma, which is likely to become the reactor of the first fusion power plant. The international ITER tokamak will be a breakthrough project for the further development of controlled thermonuclear fusion, with the main objective of testing a number of key technologies and the suitability of the tokamak as a fusion power plant reactor. According to the European Union's plans, construction of the first EU-DEMO fusion power plant should start around 2040. This bachelor thesis provides a comprehensive overview of the origins, current status and future prospects of thermonuclear fusion and its energy applications.
A comprehensive technical economic analysis of an electric car and a hydrogen vehicle
Lašák, Ondřej ; Sitek, Tomáš (referee) ; Elbl, Patrik (advisor)
Modern human society has undergone rapid technological development, and, as a result, humanity has begun to change the climate of planet Earth. The result is rising average temperature across the planet and some areas are threatened to become uninhabitable. One of the causes of global warming is the high CO2 emissions arising, among other things, from transportation. That is why transport is being diverted from fossil fuels to alternative energy carriers such as hydrogen or to direct usage of electricity. The aim of this work is to compare a hydrogen car and a battery electric car in terms of emission and energy requirements. In the last part, the economic costs of the transformation of passenger transport to these new fuels are approximated. The comparison includes current conditions and outlook to the future.
Research of the effect of desicants on moisture adsorption
Němec, Mojmír ; Lisá, Hana (referee) ; Elbl, Patrik (advisor)
Desiccants are special materials that can effectively adsorb moisture from the surrounding air or space. Desiccants such as silica gel or molecular sieve are often used in laboratory applications, for example to determine the properties of solid fuels. The introduction of the research section is devoted to the description of these properties. The thesis then describes the methods used to accurately determine the moisture in solid fuels. The main part of the thesis is devoted to desiccators together with desiccants, which form a significant part in the process of determining moisture in solid fuels. The experimental part deals with the investi-gation of the effect of different desiccants on the rate of air moisture depletion in the desic-cator under laboratory conditions. The moisture loss in the desiccator is measured using the SHT4x Smart Gadget, which is placed in the desiccator together with the desiccant. The out-put of the experimental measurements are the moisture uptake rate curves of different desic-cants for desiccant weights of 50 g, 100 g, 150 g, 200 g and 250 g. At the end of the thesis, the measured curves of the different desiccants are compared with each other in terms of efficiency.
Heating Technologies for Household Heating
Krakovič, Vojtěch ; Elbl, Patrik (referee) ; Lisý, Martin (advisor)
This bachelor's thesis presents and compares the current options for heating family houses. The first part introduces the available heating technologies and types of fuels, explains the principle of their operation, shows the advantages and disadvantages, and for which type of building each type is suitable. It will gradually introduce heating with solid fuels, gas and electricity, and continue to heat pumps and methods of obtaining solar energy. The second part introduces a model house for which a suitable heating method is being sought. Heat losses and annual heat demand are calculated. After a short discussion of suitable alternatives, two suitable options are chosen, for which the approximate initial and operating costs, as well as payback periods, are calculated. The following is a comparison and evaluation, after which we will find out the most economically suitable heating method for the model house.
