Abstract

The demand for fuel and energy resources continues to grow due to increased consumption and emerging economies in all parts of the world. With this increase in demand, crude oil prices in the international market has jumped dramatically. Global warming, which is a consequence of increasing greenhouse gas (GHG) emissions, has become scientific, social, and political concerns. To cope with global warming and energy crisis, cost-competitive biofuels are urgently needed. In addition, development of an infrastructure, which supplies energy stably and diversifies energy resources, as well as new cost-saving technologies should be developed to reduce the costs of producing biofuels. Due to high oleic acid content, rapeseed (Brassica napus L.) is currently the potential feedstock for biodiesel production in temperate zone region and the production and use of rapeseed oil is already commercialized in Europe. In Korea double-cropping (rice and rapeseed) became more prevalent because it reduces competitions from land constraints. Production of rapeseed as a biodiesel feedstock may reduce the influence of rising oil prices and nation's dependence on imported petroleum and increase job opportunities and farm incomes.

최근 원유 및 석탄 등의 가격 급등에 따른 에너지 비용이 가중되고 있으며 지속적인 상승이 예상되어 기업은 물론 개인들도 에너지 사용에 보다 많은 부담을 가지게 될 것이다. 따라서 에너지원을 다양화하고 에너지를 안정적으로 공급하는 체계 구축이 시급하며, 기후변화협약의 규제에 대응하고 기존 에너지원과의 가격경쟁력을 확보하여 차세대 산업으로 성장시키기 위한 기술 확보가 절실한 시점이다. 유럽의 경우 바이오디젤 원료 및 공업적 원료로서 식물성 유지확보에 많은 정책적 배려를 하고 있다. 식용 식물성유지의 과잉생산에 따른 폭락과 미국과의 무역마찰을 피하기 위해 농업의 재편을 시도하고 있으며, BHA (Blair House Agreement)를 미국과 맺고 우루과이라운드에 입각한 국산 보조프로그램에 관련된 문제를 해결하였다. 온대지방에서 바이오디젤 연료의 원료로 적합한 유채 기름은 이미 유럽에서 상용화가 이루어지고 있으며, 유채기름을 구성하고 있는 지방산 중에서 oleic acid 함량이 높아야 겨울철 저온유동점이 영하로 낮아져 바이오디젤을 자동차연료로 쓰기에 유리하다. 중부 이남의 농지에 2모작으로 유채재배가 국내에서 가능할 경우 바이오디젤 원료확보와 동시에 헥타르 (ha) 당 7톤 이상의 이산화탄소 ($CO_2$)저감을 주는 효과가 있으며, 농업분야에서 환경 친화적 바이오에너지 생산이 가능해 지고 농민들의 소득증대와 관상용으로 지역관광 발전에도 크게 도움이 될 수 있을 것으로 생각된다.
