Economic Feasibility and Impact Analysis on Energy Transformation Project of Macro-Algae Biomass

해조류 바이오매스 에너지화 사업의 경제적 타당성과 파급효과 분석

This study aims at examining economic feasibility, economic impacts, and CO2 reduction of a large scale project on conversion of macro-algae to bioenergy in South Korea. As feedstock for producing biofuels such as methane, ethanol, and bio-oil, Laminaria was accounted in the feasibility study. For low, medium, and high crude oil price scenarios, NPV, B/C, and IRR supported positive feasibility of this project. As economic spill-over effects, forward and backward linkage effects were over 4trillion KRW, employment effect was over 10,000 persons in 2030. For environmental effects, about 741,231TCO2 were abated due to this project in 2030. We suggested that RPS, RFS, or RHO should take account of credits on the bioenergy from macro-algae in the future.
