Implication of CO_2 capture technologies options in electricity generation in Korea

摘要

This paper estimates the future mitigation potential and costs of CO_2 reduction technology options to the electricity generation facility in Korea. The monoethanolamine (MEA) absorption, membrane separation, pressure swing adsorption, and O_2/CO_2 input system were selected as the representative CO_2 reduction technology options. In order to analyze the mitigation potential and cost of these options, it uses the long-range energy alternative planning (LEAP) framework for setting future scenarios and assessing the technology options implication. The baseline case of energy planning scenario in Korea is determined in a business-as-usual (BAU) scenario. A BAU scenario is composed of the current account (2003) and future projections for 20 years. Alternative scenarios mainly deal with the installation planning options of CO_2 reduction technology (exogenous capacity, planning time, and existing electric plants). In each alternative scenario analysis, an alternation trend of existing electricity generation facilities was analyzed and the cost of installed CO_2 reduction plants and CO_2 reduction potential was assessed quantitatively.
