“…[21], the authors considered specific power plants with certain characteristics, such as installed power, steam pressure, steam temperature or thermal efficiency. A similar case is [23], in which the authors also studied specific power plants. As far as can be known, very few studies consider more than a specific power plant for each type of energy system.…”

“…It is also influenced by the typical characteristics of the technology, such as efficiency, annual production, service life, and the nature of the energy source utilized. In Figure 4, the average cost of electricity generation for coal, NG and nuclear are comparable at a value of around 0.05 USD/kWh, for wind and biomass it is almost doubled, whereas for CSP and PV, it is particularly very high of 4 and 6 times the average values of coal, respectively [15,[41][42][43]45,46,48,59]. Surprisingly, we found in the literature [41] a wide value range for PV which again reflects the different designs and technological features.…”

“…According to several previous studies (see [15,[40][41][42][43][44][45][46]), Figure 1 shows the value range and average value of the efficiencies of electricity generation of the technologies under assessment. It can be observed that natural gas-fired power plants occupy the top efficient technology with an average value of 47%, whereas PV has the lowest efficiency of around 13% with a possible maximum of 22%.…”

Abstract:Future electricity planning necessitates a thorough multi-faceted analysis of the available technologies in order to secure the energy supply for coming generations. To cope with worldwide concerns over sustainable development and meet the growing demands of electricity we assess the future potential technologies in Egypt through covering their technical, economic, environmental and social aspects. In this study we fill the gap of a lacking sustainability assessment of energy systems in Egypt where most of the studies focus mainly on the economic and technical aspects of planning future installation of power plants in Egypt. Furthermore, we include the stakeholder preferences of the indicators in the energy sector into our assessment. Moreover, we perform a sensitivity analysis through single dimension assessment scenarios of the technologies as well as a sustainable scenario with equal preferences of all dimensions of the sustainability. We employ two multi-criteria decision analysis (MCDA) methodologies: the analytical hierarchy process for weighing the assessment criteria, and the weighted sum method for generating a general integrated sustainability index for each technology. The study investigates seven technologies: coal, natural gas, wind, concentrated solar power, photovoltaics, biomass and nuclear. The results reveal a perfect matching between the ranking of the technologies by the stakeholders and the sustainable scenario showing the highest ranking for natural gas and the lowest for nuclear and coal. There is a strong potential for renewable energy technologies to invade the electricity market in Egypt where they achieve the second ranking after natural gas. The Monte-Carlo approach gives photovoltaics a higher ranking over concentrated solar power as compared to the sample data ranking. The study concludes the importance of a multi-dimensional evaluation of the technologies while considering the preferences of the stakeholders in order to achieve a reliable and sustainable future energy supply.

Fe-zeolite catalysts were prepared by ionexchange and characterized by nitrogen physisorption, electron paramagnetic resonance (EPR) spectroscopy, NH 3 -temperature programmed desorption (TPD), H 2 -temperature programmed reduction (TPR) and Energy dispersive X-ray spectroscopy (EDX) methods. The effect of potassium doping on the acidic and redox properties of the Fe-zeolite catalysts were studied. The prepared catalysts showed high surface area and surface acidity. This is essential for increased alkali resistivity in comparison with conventional metal oxide supports like, e.g. TiO 2 and ZrO 2 , towards e.g. potassium salts in flue gases from biomass fired power plants. These properties allowed both undoped and potassium doped Fe-zeolite catalysts to posses high activity during the selective catalytic reduction (SCR) of NO with NH 3 . The extent of deactivation of the Fe-zeolite catalysts was further compared with commercial V 2 O 5 -WO 3 -TiO 2 catalyst (VWT) with various levels of potassium poisoning. While VWT catalysts severely deactivated at relative low potassium concentration levels the Fe-zeolite catalysts also showed superior alkali resistivity even at high potassium loadings.
