“…According to him, biogas production in sewage treatment plant in Chania is 1,085 NM 3 /day and in the respective plant in Heraklion 3,200 NM 3 /day. Investigation of biogas produced in the landfill of Heraklion Crete for power generation has been presented (Tsave et al, 2008, Karapidakis et al, 2010 ). An average biogas production from the landfill over the period 2006-2026 of 1,636.68 NM 3 /h has been estimated and assuming that 75% of the produced biogas can be recovered, its energy content is 55.95 GWh/year.…”

Biogas is currently produced in Crete-Greece from the two existing landfills in the island, as well as from the sewage treatment plants in Chania and Heraklion. Biogas produced in the two treatment plants is already used for co-generation of heat and power. However, since the quantities of landfills biogas and its energy content are significant, it can be used in the future either for heat production or for heat and power generation. Generated power can be fed into the grid and the produced heat can be used from a heat consumer. Since large heat consumers are not located nearby the existing landfills, there is the possibility for the creation of agricultural greenhouses in the surrounding agricultural areas which can utilize the generated heat. Landfill in Heraklion has an average biogas production of 1.43x10 7 NM 3 /year, almost five times higher than the landfill in Chania and the totally recoverable biogas from the two landfills can generate 16.73 GWh/year of electricity, in the case of a CHP plant, and enough heat for heating 15.4 hectares of modern greenhouses. In the case of direct heat generation, recoverable landfill biogas can heat 24.41 hectares of modern greenhouses. Since the global warming potential of methane is much higher than CO 2 , energy exploitation of landfills biogas in Crete will result in environmental benefits compared with its direct emission to the atmosphere.

Biogas resulted from anaerobic digestion of organic compounds have various methane content depend on the type of the degraded material. The methane content of biogas is range between 40–80% that influence the heating value and combustion characteristic of that biogas. The higher methane content can be obtained through upgrading biogas by removing CO2 and other trace components like H2S, NH3, and water vapor. This research was a simulation of product composition and temperature of biogas combustion in various methane content and air biogas equivalence ratio. Biogas combustion was done in combustion chamber at constant pressure of 1 atm. Biogas and air enter into combustion chamber at temperature approximately of 30 °C as the common ambient temperature in Indonesia. The input air was designed higher than stoichiometric need in order to reach complete combustion. Combustion reaction between methane and O2 then carried out in the combustion chamber to produce CO2 and H2O. The product gases consisting of CO2, H2O, N2, and excess O2, bring heat from combustion reaction and exit from combustion chamber at the higher temperature. The analysis was done for methane content range between 20 and 100% with air biogas equivalence ratio from 1 until 3. The simulation result showed that for V m3 biogas, the combustion gases could reach 0.12271 until 1.26798V gmol with temperature above 700 °C until above 1900 °C. More than 50% component in the combustion gases is N2 as inert material from input air to combustion chamber.

“…From a structural point of view, an energy system is a combination of different subsystems with numerous actors within them. As an example, renewable energies are just a subsystem of the energy system, in which diverse actors, in public, university and business sectors, could be identified (Karapidakis et al, 2010). One can understand this complexity from a process oriented point of view.…”

ABSTRACT:In the past, decision making within the energy sector, especially in Iran, was limited to economic analysis. Lately, multiple criteria decision making has gained great popularity. However, this is not enough to make a right decision by considering sustainability. This paper deals with designing an appropriate multiple criteria decision making method to address the multifaceted nature of such problems. This task is the second precondition to make a decision which meets the sustainability criterion. This is done by revealing new facts about quantitative and qualitative data and the degree of compensation between the criteria. Moreover, this paper illustrates the capability of different methods with regard to sustainable energy planning and management in two steps: 1) comparison of two main approaches in the strategic energy planning context; 2) evaluation of multi attribute decision making methods and combining them. Combining four methods including Analytical hierarchy process, Preference ranking organization method for enrichment evaluation II, geometric mean and weighted sum seems to result in designing an appropriate method which meets the sustainability criterion. These contributions are proposed for comparing the renewable energy technologies with nonrenewable ones. Nevertheless, these seem to be applicable in any comparison between discrete alternatives in the energy sector.
