Integration Of Biogas Technology Into Power Generation In Sri Lanka.

Abstract

The integration of biogas technology into power generation system in Sri Lanka, is studied and analysed, as a possible solution to raising problematic situation in Colombo city from generating MSW. To fulfill this requirement, present energy scenario in Sri Lanka, literature review and global development of biogas to power, case studies related to biogas technology, data collection of MSW to estimate the potential of biogas from OFMSW in Colombo city, analysis of data, developing a plan for a biogas power plant and evaluation of the proposed plant, are discussed. It is investigated and identified the biogas potential from OFMSW generating in Colombo city and electricity potential from produced biogas. It is synthesized to select the suitable digester technology and conversion technology to generate electricity from OFMSW, to continue the study. Further it is calculated and compared the key financial indexes such as NPV, IRR and payback period for the selected scenario, for several cases, to find out the financial viability of the proposed power project as well as evaluated the project under several aspects, to conclude the objective of this study. Further, it is revealed that the integration of biogas technology into power generation system is financially viable for all cases.
