해조류를 이용한 바이오연료의 환경 친화적 적용을 위한 기초연구 = A Preliminary Study for Environmentally-friendly Application of Biofuel using Marine Biomass

다국어 초록 (Multilingual Abstract)

Biofuel has recently received a lot of attention as a main viable technology that can reduce the greenhouse gas emissions and replace petroleum-based transport fuel. The International Energy Agency (IEA, 2011) predicted that biofuel can play an important role in reducing CO2 emissions in the transport sector and could provide 27% of total transport fuel by 2050. The United States and EU are pursuing the commercialization of bioethanol and biodiesel, respectively, and fostering bioenergy industry through intensive support and investment. Korean government also established a plan that the weight of renewable energy compared to total energy weight will be 11% by 2030 and has raised the biodiesel industry for the reduction of GHG emissions, improvement of air quality and enhancement of energy security with「The basic plans on renewable energy`s technical development, and utilization and popularization」and「The spread plans of biodiesel for medium and long term」, respectively. Biofuel is sustainable and carbon-neutral because it can be produced from biomass which is plentiful and absorbs CO2 to grow through photosynthesis. This research focused on both biodiesel and bioethanol and was performed as a preliminary study to seek policy direction for environmentally-friendly popularization of marine biomass-based biofuel. First of all, the present status of biofuel related technology development was reviewed according to the type of biomass (Chapter 2). Also, current situation of advanced country`s policy trends was examined (Chapter 3). Based on review materials such as foreign researches and policies for biofuel, the United States and EU are actively investing on the development of technology using next-generation biomass to extend biofuel industry and obtain the competition through the integration of biorefinery. In addition, the effect of biofuel on environment is considered through biofuel sustainability standards. Chapter 4 includes policy directions with the current status of domestic policies. For the popularization of next generation biomass-based biofuel, sufficient prior consideration of environmental effects is necessary with the active support on R&D and assessment of environment load and the solutions to reduce the environment effects are required. Based on such contents, there is a need to arrange institutional mechanism that can sufficiently consider related environmental effects prior to pursuing domestic biofuel commercialization in a future.
