Sustainability Assessment of the Wind Energy Utilisation

Multicriteria sustainability assessment based on ASPID methodology is used for sustainability evaluation of wind energy utilisation in Bosnia and Herzegovina. The point of the used method is in synthesis of specific criteria which describe various aspects of the objects (in this case energy systems of various sources) on the base of initial attributes or indicators, and which are being evaluated by General index characterising all options under consideration. This basic method-MGI (Method General Index) is adopted by ASPID methodology {Analysis and Synthesis of Index at Information Deficiency) [5, 6].

[12] Portaria n.° 228/1990, 27th March, approves the regulation for management of energy consumptions for the transport sector.

Competing Uses of the Maritime Space

Having in mind the increasing maturity of wave energy technology, it is opportune to investigate the main concerns and issues over the Portuguese coast to large-scale development of wave energy basically arising from competing uses of the ocean space.

In the maritime domain there are several players and entities with different interests and competences, so that it is important to try to understand and, if possible, to conciliate the different viewpoints. The experience from offshore wind energy has demonstrated that this is a difficult task, which has to be approached as early as possible...

Integration of the Parabolic Trough Collectors and Power Plant Simulation

The concept of integrating the parabolic collectors into the cycle is illustrated in Fig. 6. The temperature level of the solar steam is high enough to be integrated into the high – pressure preheater section and to preheat a part of the boiler feedwater. Thus the preheater’s steam consumption is reduced and the steam remaining in the turbine can be used for an additional power generation. The condensate leaving solar preheater 1 is still at a temperature level to preheat a part of the feedwater in the low pressure preheating section (solar preheater 2). The main part of the feedwater is heated in the preheaters 1 to 4 by extraction steam conventionally.

[7] Conclusion

The integration of external solar generated steam into the water steam cycle of conventional steam power plants is a pro...

A Novel Concept of an Ecological Engine

This work concerns a novel concept of diesel engine, which was invented, developed and investigated in Technical University of Radom. The concept consists in dual fuelling: a base fuel, which in the first approach-is diesel fuel (DF) and-in the second approach – rape oil methyl ester (RME) is injected by the standard fuel system and additionally ethanol is injected into inlet port during suction stroke, in order to enhance burning of DF/RME fuel droplets. Before self-ignition of DF/RME ethanol forms with air homogeneous mixture. After ignition by burning DF or RME droplets (which have self-

The hot gases from the recirculation cyclones are cooled initially in a heat recovery steam generator and finally in combustion air preheaters...

Multicriteria Sustainability Assessment

The multicriteria sustainability assessment based on ASPID methodology {Analysis and Synthesis of Index at Information Deficiency) [5, 6] of the energy power system under consideration is performed. Used methodology is based on the system of stochastic model of uncertainty, enabling to obtain the assessment from of various supporting systems by computer, as well as enabling to obtain various normalization indexes by using Non­numeric (ordinal), Non-exact (interval) and Non-complete information (NNN- information), obtained from sources of various reliability and probability...

Results of Single Criteria Analysis

The results of single criteria assessment within the analysis are presented. Comparing the considered options according to the environment indicators, e. g. see Fig. 2-indicator of sulfur dioxide emission, it can be noticed that renewable resources, hydropower plant, and clean fossil fuel technologies as Combined cycle gas turbine station and fluidised-bed combustion, are in advantage in reference to the reconstructed conventional coal-fueled stations.

Fig. 2. Comparision of S02 indicators within single criteria analysis

The opposite to this, the comparison of economic indicators, e. g. indicator of investment—see Fig. 3, options of coal-fired power plant is preferable in comparison to the renewable resources.

These are obvious examples of unreliability of single criteria analysi...

Sustainability Indicators

The sustainability assessment is based on the definition and calculation of sustainability indicators. In this work, sustainability indicators reflecting 4 criteria of sustainability are defined and given in Table 1.

Indicators from Table 1 are calculated for all options under consideration; on the base of that single criterion assessment can be performed.
