APPLICATION OF MULTI-CRITERIA DECISION MAKING FOR GEOLOGICAL CARBON DIOXIDE STORAGE AREA IN TURKEY.

In contemporary era, carbon sequestration has become an important issue. Rapidly increasing population, higher lifestandards and technological advancements consistently increase the amount of emissions, especially CO2. Nowadays, the most promising solution is to minimize the carbon dioxide emissions with using carbon capture and storage (CCS) technologies for a better future. The problem is to choose the best location for CO2 storage which is a crucial and challenging multicriteria decision problem. The objective of this paper is to determine the most appropriate city for carbon dioxide storage in Turkey, by demonstrating a successful implementation of Multi-criteria Decision Making (MCDM) tool. This study presents the use of MCDM method based on Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to assess the suitable location for CO2 storage. For that purpose, 4 alternative locations were evaluated via 8 criteria which are determined according to the opinions of the experts with background information from the field. Towards this end, MCDM method, namely, TOPSIS, was utilized for the location evaluation. Consequently, this method detects Diyarbakır as CO2 storage area which is also one of the most important city of Turkey for having finished oil reservoirs and for its geopolitical location.
