Securing an International Role Through Energy: The Case of UAE
Kováčová, Marína ; Kalhousová, Irena (advisor) ; Buriánek, Petr (referee)
The aim of this bachelor thesis is to elucidate the energy policy of the United Arab Emirates (UAE) and to explain its motivation through the neorealist theory of international relations. The UAE possesses one of the largest global hydrocarbon capitals. Recent years have shown that despite its oil and gas wealth, the country is intensifying its investments in renewable transition and enhancing sustainable energy policies. This thesis attributes the motivation for such change in direction to the interest in anchoring economic and political security on the international stage. The thesis is systematically divided into two main parts, the first of which outlines the theoretical grounding of the topic in the context of international relations, while the second offers empirical examples of specific policies implemented by the country. I concurrently link the identified policies with neorealism and highlight their importance in the country's foreign policy. Keywords United Aram Emirates, Energy, Renewable Energy, National Interest, COP28, Neorealism, Political pragmatism

Cuřín, Martin ; Charvát, Pavel (referee) ; Klimeš, Lubomír (advisor)
The liquefaction of gaseous fuels using renewable energy sources is a promising method for the efficient transportation and utilization of these fuels. This thesis primarily addresses the issues related to the liquefaction of natural gas, from its conditioning, liquefaction, to its storage and transportation. The economic balance evaluates three proposed scenarios for the transportation of natural gas to the Czech Republic. Additionally, the economic viability of using renewable energy sources for the liquefaction of natural gas is analysed. The aim of the thesis was to provide a basic overview of current liquefaction tech- nologies and to analyse the use of renewable energy in the process of liquefaction and seasonal storage of natural gas. The results indicate that the use of renewable sources for liquefaction can be economically advantageous and beneficial in the sustainability of the energy sector.

Multirotor wind power plant for the Czech Republic
Boršoš, Adam ; Linda, Jakub (referee) ; Škorpík, Jiří (advisor)
As the power of wind turbines increases, the rotor diameter usually increases as well. This complicates transportation and handling. The multirotor power plant concept has the potential to minimise this problem. In this paper, various aspects of multirotor power plants have been described in general terms. The landscape of the Czech Republic has been analysed in terms of conditions for wind power plants and consequently a suitable site for the location of a multirotor power plant has been selected. This was followed by the selection of the wind turbine model for the multirotor design. After calculating the outputs and comparing the key parameters of the three models, the most suitable model was selected. This was followed by the actual design of the structure, which was created according to the results of the strength analysis in SolidWorks. Finally, a calculation of the dimensions of the equivalent single-rotor wind turbine was made and the corresponding model was selected. Also, the designed multi-rotor power plant was compared with the wind power plants surrounding the selected location.

The energy crisis and its possible solutions in a selected municipality in the Czech Republic
NOVOTNÁ, Karolína
The thesis focuses on the energy crisis and its alternative solutions within a selected municipality. Three research methods were used in the thesis, namely a questionnaire survey, a household real consumption survey and a semi-structured interview. The aim of the thesis was to find an alternative solution and then to determine the willingness of the residents of the selected municipality to accept it, given a higher price offer, in relation to the completed education of the individual and his/her income category. A biogas plant located near the selected village was offered as an alternative source of electricity, where the aforementioned interview was also conducted. The interview served to establish the feasibility of this proposed solution. The work was conducted as a community energy sector model where the biggest source would be a biogas plant.
