Methodological Approach to an Integrated Assessment of Systems for Remote Renewable Energy Supply

Abstract

The use of renewable energy sources to reduce greenhouse gas emissions has become a global trend. According to forecasts of various international energy research organizations, this trend will persist in the future. As resources located near consumption centers are developed, the long-distance renewable energy transportation from areas where renewable sources operate with greater efficiency becomes a more pressing issue. Thus, the objective to establish an energy system using remote renewable sources arises. The study aims to elaborate a methodological approach for an integrated assessment of systems for energy supply from remote renewable energy sources. A distinctive feature of the proposed approach is a separate analysis of the main technological processes of production, conversion, storage, and use of energy carriers, with specific attention given to the generation of electricity from renewable energy sources. The Technique for order of preference by similarity to ideal solution (TOPSIS) is used for multi-criteria analysis of various solutions. This study aims to compare different energy systems for a project designed to export renewable energy from Russia (Sakhalin Island) to Japan (Yamagata Prefecture).
