Hydrogen production from renewable energy source
Lakva, Petr ; Baláš, Marek (referee) ; Jícha, Jaroslav (advisor)
Hydrogen, as a form of storage for the excess energy from renewable sources, is a technically and economically viable option. However, the technology is not mature enough to compete with the other renewable energy possibilities. In this thesis, a study based on coupling two 330 kW wind-turbines with an NELP. 40 electrolyzer this connection should improve the utilization of wind power. In this thesis are two options of energy utilization. The energy produced by the wind-turbine is stored in the form, of hydrogen and is then delivered for consumption at variable power through a fuel cell, second option is use of produced hydrogen as alternative fuel for cars. This study is a general introduction for the wind energy system with hydrogen storage. Future studies should be more complex and detailed in order to understand and model the system with greater accuracy and to increase the possibility for the utilization of wind energy to generate hydrogen. This would enhance wind power competitiveness and sustain the continuously changing world energy demands.

Expert system for choice of proper method for waste utilization
Fikar, Josef ; Jícha, Jaroslav (referee) ; Dvořák, Jiří (advisor)
This work consists in development of expert system intended for choosing appropriate method of waste processing. The software is created in VisiRule software which is built on Prolog language and is part of WinProlog 4.900 development tool. It also deals with problematics of creating of knowledge base for applications of this type and judging of suitability of possible approaches to creating an expert system for given purpose.

System for heat recovery of gas microturbine flue gas
Vilda, Dalibor ; Jícha, Jaroslav (referee) ; Máša, Vítězslav (advisor)
The theme of the work is the integration of gas microturbines in industrial plants. The aim is to extend the application potential of this technology by the design of the integration into the process in which this technology is not exploited yet. This process is a professional laundry service. Professional laundry services have been selected as a representative of the generally known process, which is interesting in terms of energy intensity. Combining of progressive cogeneration technology and enhanced industrial process brings a promising application potential. The work focuses on small industrial laundries to 500 kg of processed linen per shift. As a cogeneration unit a gas microturbine Capstone C30 has been used. The microturbine has an adequate power due to the process. Complete laundry operation and a gas microturbine is a part of the equipment of the Laboratory of energetically demanding processes in the NETME Centre. The main contribution of this work is to design a system for utilization of flue gas heat for heating of the main input currents to the laundry room, a hot water for washing machines and warm air for drying in the dryers. The integration of the gas microturbine made to suit specific process can be a major cost-saving measures with positive impacts on the economy of operation.

Legislature of European Union for the waste disposal.
Polák, Marek ; Beňo, Zdeněk (referee) ; Jícha, Jaroslav (advisor)
This bachelor thesis acquaints with legislation on enviroment protection in Czech Republic. The main part of this thesis is waste management oriented, especially to the waste law in Czech Republic, then is maked the mention of the waste legislation in Austria and Germany. The next point of this thesis is refering to waste conditioning by combustion, disposal and recycling and then comparing the states in theese ways of waste conditioning is mentioned .

Microwave induced pyrolysis of biomass
Šmarda, Marek ; Gal, Pavel (referee) ; Jícha, Jaroslav (advisor)
In this bachelor thesis there are informations about different methods of processing organic nature substrate with a focus on a waste processing using microwave pyrolysis. In sum it is possible to say that microwave pyrolysis is a progressive solution to process waste substrate. Due to evenly and rapid heating of organic nature substrate, this method is more effective compared to conventional methods of waste disposal. The result of this work is to submit information on processing waste substrate in the form of microwave analysis and subsequent economic evaluation.

Life cycle assessment of municipal waste
Vlach, Josef ; Slavík, Jan (referee) ; Jícha, Jaroslav (advisor)
The aim of this study is to present methodology life cycle (LCA) and Life Cycle Assessment of disposal the municipal solid waste chain. There is described the procedure of generation of the LCA studies according to the standards ČSN EN ISO 14 040 and ČSN EN ISO 14 044 in the first and second part. In the third part of this diploma there are described LCA analyses that have already been created. The software GEMIS (Global Emission Model for Integrated System) is described in the fourth part. The computer model GEMIS has been used as a calculation tool in this study. The fifth part of this study includes waste management and different kinds of disposal municipal solid waste. In this part is describe basic data about landfilling and incieration. There is shown LCA analysis of disposal municipial solid waste in the sixth part. Data processing was carried out by means of the software GEMIS 4.3. The results were interpreted for incineration and landfilling. Finally there is mentioned results for 1 TJ different elektrical energize to.

Evaluation of technology for the biomass incineration.
Trna, Lukáš ; Tabasová, Andrea (referee) ; Jícha, Jaroslav (advisor)
The objective of this bachelor‘s thesis is to provide general information about biomass and technologies for its using. The thesis is diveded into four main parts. The first part describe sources of biomass, its adaptation and its processing for energy purposes. The second part is more comprehensive and mentions individual technoligies and possibilities of final using of biomass. The third part sums sup ecological falls and efects of production biomass on environment. The fourth part deals with economics and compares costs of the most available technolgies for gaining thermal energy.
