Abstract

Iran is on the verge of elimination of energy subsidies. This means a sudden increase in prices such as gas; electricity; etc.... On the other hand; the different means of the different means of energy production is a great concern for human being. Amongst all different methods of energy production; renewable energy is paid more and more attention due to the least consequences concerning the diverse climate change effects. However; the economic factors are also important in order to bring a project into reality. In this paper; the potential of biomass energy in an industrial scale is investigated under this great change on national policies. Then the economic analysis of an industrial biogas system in a rural area near the province of Tehran; the capital of I.R.I.; as a case study is illustrated .In this process several products will be produced such as organic compost by anaerobic fermentation of agricultural and organic wastes; liquid fertilizer; Methane and Carbonic gases; electricity and heating. The results of economical evaluation shows that the use of methane-fired generators for the production of electricity is economical because of the high amount of biogas production. So; the revenue gained from produced electricity is more than produced compost. Also; in the process of biogas production; the huge amount of Carbonic gas will be produced which can be used after purification in industry. The result show a promising future for the use of bio gas; specially under new policies of zero energy subsidies for households ; commercial; and public use.
