Fourth-generation biofuels for jet engines
Marko, Adam ; Mišík, Ondrej (referee) ; Malý, Milan (advisor)
The bachelor thesis deals with the decarbonisation of air transport and the possible use of biofuels to power jet engines. As the use of the current fuel, kerosene, is time limited due to finite oil supplies, research and testing of its environmentally friendly successors is necessary. Equally important is the parallel development of compatible aviation and airport infrastructure, both in the form of airframes, engines and fuel systems and ground support equipment. In the event of a transition to a new type of aviation fuel, it is essential that it is technically advanced, affordable, environmentally sound, safe and has a wide supply chain. Currently, the scientific community is most focused on the use of sustainable aviation fuels SAF, hydrogen, ammonia, LNG and e-fuels. To qualify as a biofuel, the production process must be carbon neutral and the primary source of production must be renewable energy.

The development of energetics in the Czech Republic during the following years
Musil, Miloš ; Kracík, Petr (referee) ; Toman, Filip (advisor)
This thesis analyses the current Czech energy sector. It describes its current state and outlines possible scenarios of its development in future years in the context of the energy transformation. The thesis seeks to analyse the current situation of the energy sector in the country, assess its strengths and weaknesses and identify opportunities and threats for future development. The thesis describes the different parts of the Czech energy sector, such as the electricity, gas, heating and oil industries, including production sources, consumption and emissions. Most emphasis is given to the electricity sector. The capacities and potentials of the different sectors are analysed alongside the possible future scenarios outlined. Part of the thesis is also focused on describing and explaining the composition and construction of electricity and gas prices in the Czech Republic. Emphasis is also placed on placing the Czech energy sector in the broader context of the energy sectors of European countries and includes various scenarios for the development of the electricity sector in Europe. In the context of the current geopolitical situation in Europe and the modernisation and transformation of this sector, it is necessary to build new energy sources.

Energy Balance of Smart Ventilated Facade
Salajka, Radek
This article explains the function and basic energy balance for a smart facade system that is being researched at Brno University of Technology. This system is an upgrade to an already well-known ventilated facade. The upgrade is mainly presented by efficient control over built-in shut-off dampers inside the ventilated gap. The main goal is to reduce the energy consumption of buildings and create a healthy and comfortable indoor thermal microclimate in a much more ecological way. Numerical calculations are being used to present the energy use of a given facade in comparison with other conventional facade systems on the same building with identical boundary conditions. FSVM software which provides these calculations has been developed by the same research team. It can calculate the energy balance of conventional facades, ETICS and prototype of smart facades as well. This article presents ongoing research and results of the simulation of the heat flow of these three main facade systems throughout the year. Significant variables for facade heat flow calculations are weather and outdoor boundary conditions. They are used in this article as conditions for the Czech Republic which has a mild climate and four different seasons of the year.

Process computer simulation
Čech, Michal ; Pavlas, Martin (referee) ; Touš, Michal (advisor)
The thesis deals with computer simulation of processes, which is crucial in the field of process engineering. In the first part, the methodology of modeling and simulation techniques is described as well as mass and energy balances. Specific approaches to process simulation are included. The thesis offers a list of the most often used simulation programs and their typical structure. Sequential modular and equation-based simulation is demonstrated on an example. The results are then verified by simulation software W2E.

Utilization of waste heat from rectification
Frank, Vojtěch ; Konečná, Eva (referee) ; Touš, Michal (advisor)
The purpose of the thesis is to draw up a model of the energy and material balance using technical and technological analysis of the current state of production of waste heat in the process of distillation. Using these results, subsequently evaluate the energy potential of individual streams and propose optimal energy savings using waste heat. Emphasis is placed on the modelling of the process and the various proposed savings options. The result is also an evaluation of the potential of the proposed savings based on the results of the calculation.

Operating costs of passive houses
Baranyková, Zuzana ; Chovancová, Jitka (referee) ; Výskala, Miloslav (advisor)
The main topic of this thesis is the comparison of operating costs (energy balance) of a passive house with running costs of a house of an ordinary construction. Total operating costs of those types of construction are determined and the houses are subsequently divided into groups according to their actual consumption and a comparison of the different types of construction is carried out.
