Effectiveness in reducing costs in heating
Chytil, Michal ; Zlevorová, Tereza (referee) ; Lisý, Martin (advisor)
Heating of family houses, due to its significant energy consumption, ranks among major sources of pollution worldwide and at the same time represents a considerable item in household budgets. This Batchelor thesis deals with the possibilities of saving energy in heating family houses and their economic viability. The thesis includes a list of options for reducing heat loss and subsequent comparison of basic types of heating. At the end there is a model calculation of individual variants and their economic comparison in terms of financial return.

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.

Potencial of RES in the Czech Rep
Kříž, David ; Zlevorová, Tereza (referee) ; Lisý, Martin (advisor)
In today's modern age, we still predominantly rely on non-renewable resources, the utilization of which further harms our planet Earth due to the significant greenhouse gas emissions. In order to reduce emission levels and the continuously increasing energy costs due to the diminishing supply of fossil fuels, humanity is striving to find alternative sustainable resources and methods for the future. The greatest hope for change lies in renewable energy sources. This work initially focuses on researching the currently available renewable resources in the Czech Republic, their gradual development throughout history, and their utilization methods here. Further information pertains to the projected development and potential of renewable resources in our country in the coming years, how we are capable of meeting the requirements set by the European Union, and what new technologies could be helpful in this regard. The final section presents a comparison of some significant European countries and selected neighbors in terms of the proportion of utilization of these resources.

The Effect of Biomass Storage on the Fuels Parameters
Zlevorová, Tereza ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
This thesis investigates the effect of storage on the basic properties of fuel. The first part summarises basic knowledge of biomass, its properties, storage methods and related problems. This is followed by an experimental part, which aims to investigate predicted decrease in the calorific value and volatile matter of materials due to spreading degradation. The experiment is based on repeated measuring of the properties of samples stored for thirteen weeks at three different temperatures and moistures. The results are graphs that show a decreasing trend in most cases. They also show differences in the extent and rate of degradation depending on the type of material and the ambient conditions.

Effect of sample treatment on biofuel characteristics
Zlevorová, Tereza ; Lachman, Jakub (referee) ; Lisá, Hana (advisor)
The subject of this bachelor thesis is experimental solution of the problem focused on the effect of sample treatment on bioful characteristics. The theoretical introduction includes biofuel classification, explanation of each biofuels‘ trait and description of methods used to their determination. It continues with sample preparation with broader focus on milling. The following experimental part examines basic traits of four materials before and after milling on high-speed rotor mill using multiple sieves of varying fineness. The traits were determined using normalised methods. For determination of moisture had been selected gravimetric method. In this thesis, there is described every procedure and following calculations. The results are stated in tables and processed in graphs.
