The diploma thesis is focusing on the seasonal energy storage in synthetic fuels and the Power to Gas system (P2G). The P2G enables the conversion of electrical energy in times of electricity surplus, for example by using the surplus from renewable energy sources to produce synthetic gas, particulary hydrogen and synthetic methane. The main focus is on the technical and economic assessment of P2G of the Gazela natural gas pipeline. Furthermore, it identifies the limits of production, transportation, and storage capacities of these synthetic gases. The technical analysis assumes the injection of hydrogen of a certain molar concentration, according to the four proposed scenarios, into the natural gas transmission system in the Gazela pipeline. The results have showen that an increase in the molar fraction of hydrogen in natural gas will cause problems in gas transport and will lead to an increase in the pressure losses, an increase in flow rate, and a decrease in the storage capacity of the pipeline. The economic analysis examines the use of P2G technology in Czech conditions. It demonstrates the amount of production costs for the production of 1 MWh of synthetic gas depending on the electricity price and the operating time of the production facility. The sensitivity analysis has shown that neither hydrogen nor synthetic methane is competitive next to cheap natural gas unless measures like an increased price of emission allowances or a carbon tax are taken.

This diploma thesis deals with the issue of accumulation of electricity produced by renewable sources. The first part focuses on the description of possible ways of accumulation, especially with focus on those methods, that are suitable for renewable energy sources. The next part deals with the design of the accumulation energy in the compressed air for the selected photovoltaic power plant. The necessity of designing a particular method of energy storage, is also its technical and economic analysis, which is the content of the last part of the thesis.

This masters thesis deals with the use of off-grid photovoltaic systems. First we explain the problems associated with the power and energy potential of photovoltaic system components, design of photovoltaic systems for autonomous operation and the financial evaluation. The result of the masters thesis is to create an application used to design the island system in the whole output range (the smallest power systems to house systems application). The conclusion of the masters thesis is devoted to designing three type of projects from our application – a garden cottage, a family cottage and the house.

This master thesis summarizes history of electric vehicles from its inception to present. Vehicles are divided into three groups according to the type of drive, special attention is paid to electric vehicles. Furthermore, typical ways of electric energy storage are presented, especially in the form of electrochemical cells, which are used in electric vehicles. The thesis also describes the situation of electromobility in the Czech Republic, namely government support, distribution companies tariffs, charging infrastructure and available electric vehicles. Finally, the concept of connecting electric vehicles to renewable energy source is described, with financial calculations for three profiled drivers.

This work is specialized on problems accumulation electricity power from renewable sources and production electricity power from renewable sources for select object. First part describes renewable sources and their use in our conditions. Second part is specialized on accumulators specific for renewable sources. Third part compare to production electricity power from photovoltaic power station and windy power station and their combination for select object. Further accumulation these select sources. Final fourth part describe about their comparison from position how of technical so economic.

The goal of this diploma thesis is suggest solution of ventilation and heating of industrial building. The solution is primarily based on calculation of thermal losses and thermal gains of the building. The project deals with supply of air for individual parts of construction in summer and winter. The solution consist of proposal of ducting and calculation of air handling units and unit heaters. The system of ventilation and heating is process in drawing documentation.

This diploma thesis is specialized on problems of electrical energy accumulation from renewable resources. This renewable resources used in Czech Republic are described in the first part. Next, in the second chapter is identification with principles of electrical energy accumulation. In the third part, there is a proposal of electrical energy accumulation system which makes a supply of electrical energy from photovoltaic system by the help of accumulation system in compressed air equally. In the final part, there is a total analysis of technical economic aspect for proposed system.

The diploma thesis is focused on problem of accumulating electric energy from renewable resources. The first section describes renewable energy sources, which are possible to use in the Czech Republic and principles of accumulating electric energy. In the following section are suggested systems of accumulating energy to accumulators by compressed air and pumped storage power station. These systems are proposed for uniform power supply from photovoltaic power station to electric power network all day. In conclusion, the suggested systems are compared from economic-technical perspective.

The aim of this Graduation Thesis is to devise a system of energy supply intended to provide supply of electric and heat energy to a vacation property. The main feature of this energy supply project stands for a shift from mains power supply to alternative energy supply using renewable resources. The reason for this change is the fustiness of power lines and their negative effect on the surrounding landscape. Due to the fact that authorities did not permit renovation of these power lines, the only way to preserve the functionality of the vacation property is to secure its power supply by employing renewable resources. The vacation property (a mountain cottage) is located in Hrubý Jeseník Mountains, approximately 15 kilometers from the town of Šumperk. The thesis also contains a description of the way outlying settlements are currently supplied with energy, including the possibility of accumulation and a brief description of each electrical appliance’s power consumption. In the design itself, I calculated the necessary collector surface and analyzed the most effective collector placement. As for the wind energy system, I had to found the best spot to place the turbine. Last but not least, the thesis contains the technical-economical comparison of the proposed alternatives.

In this thesis I deal with problem of power acumulation from renewable energy sources. First part present the available technologies used for power accumulation. In the second part is designed the systém of acumulation in compressed air with a transformation electric output 1 MW, when is used made elektricity from wind-power plant. In the third part is an assessment in terms of both technical and economic comparison with the use of electicity from the network.
