Summary
There has been significant rising interest in technologies involving hybrid power generation systems, mainly for ecological reasons. The key factors are the increasing proportions of regenerative energy and on the other hand reducing carbon dioxide (CO2) emissions. In order to give this a structure, the existing systems for the utilization of regenerative energies must be expanded and improved. New technologies and concepts are being investigated and introduced in combination with an increase in the efficiency of systems for fossil primary energy carriers.
There are a good number of technologies and systems which can convert different types of primary energy into electric energy and heat. This conversion takes place through different processes involving chains of several steps until the desired energy form is available. Electricity generation requires an additional generator to convert the mechanical energy using rotating machinery and combustion engines. Depending on the primary source of energy, the increase of internal energy is obtained in the combustion chambers and reactors respectively, or by the application of heat exchangers. Heat is an essential part of the conversion chain, contributing to the increase of internal energy of the fluid in all energy conversion processes. The only differences are in the temperature level of the heat and the resulting use of the heat. In the case of thermal turbo machines and combustion engines, the usable heat is available in the exhaust gas. For the conversion of chemical energy in electrical energy by fuel cells, the heat necessary for a chemical reaction in the stacks can be used to provide usable heat too.
The primary requirements for an economically attractive technology are high flexibility for diversified electricity and heat supply along with high utilization of fuel. Such technology can be effectively used for decentralised electricity supply especially by using fuel such as natural gas which is relatively less expensive than coal or oil. Also, the high utilization of fuel leads to a great reduction in the emission of CO2. Besides, coupling systems like micro gas turbines (MGT) and high temperature fuel cells have created the possibility of a power plant with an efficiency of 75% or greater.
