요약문

정부, 공공기관 그리고 각종 산업체의 에너지원과 관련된 의사결정을 지원하기 위하여 1998년 Lippiatt의 BEES모델을 참고로 하여 액화천연가스, 석탄, 오일 등과 같은 에너지시스템의 환경·경제성의 통합분석을 시도하였다. 이때 환경성은 ISO14040's 에 기반한 LCA 기법을 활용하였고, 경제성은 건설비, 운전유지비, 연료비로 구성되는 발전단가를 기초로 하였다. 또한 환경·경제성의 통합분석은 환경성과 경제성의 상대적인 가중치에 따른 시뮬레이션분석을 기초로 하였다. 본 연구수행 결과 발전소 이용율을 60%로 가정했을 때, 액화천연가스는 환경가중치가 30% 이상일 때 가장 바람직한 에너지원으로 나타 났으며, 환경에 대한 가중치가 높아질수록 액화천연가스의 환경경제통합지수가 유리해지는 경향을 볼 수 있었다.

Abstract

In order to support decision making of energy related policies of government and industry, intergrated environment & economic analysis applying the BEES(Building for Environmental and Economic Sustainability, Lippiatt) model has been tried to simulate for finding the best alternatives of energy resources such as coal, oil, and LNG. To achieve this aim, LCA tool has been applied to the environmental analysis based on ISO14040's, while the unit price for generating 1GWh electricity including construction cost, operating cost, and fuel cost has been considered for the economic analysis. Integrated environment & ecomomic analysis is based on the result of simulation according to relative weigting of environment and economic importance. As the result of research, LNG over thirty percent in environmental weighting(seventy percent in economic with regard to relative importance) is the best fuel resource for generating electricity, when the operating rate of power plant is the sixty percent. Furthermore, the higher environmental weighting in relative importance is, the better integrated environment and economic result to LNG power plant is.
