2013년 기준 국내에서 상용화 규모로 생산되는 바이오에너지 종류는? | 2013년 기준으로 국내에서 상용화 규모로 생산되는 바이오에너지에는 매립지가스, 흑액, 우드칩, 목재펠릿, 하수슬러지 고형연료, 폐목재, 바이오가스 및 바이오디젤 등이 있다[8]. 이 중에서 매립지가스, 흑액, 우드칩, 목재펠릿, 하수슬러지 고형연료, 폐목재, 바이오가스 등은 전기부문의 공급의무화 제도인 RPS 제도에서 바이오에너지로서 공급인증서(Renewable certificate, REC)로 적용되고 있다. | |
바이오오일 생산 방식은? | 바이오매스의 에너지 전환기술 중, 최근 주목 받는 기술에는 바이오오일 생산 기술이 있다[9-13]. 바이오오일은 바이오매스를 산소가 없는 조건 하에서 500 ℃ 내외의 고온에서 짧은 시간 동안 반응시켜 연료로 전환시키는 급속열분해를 통해 생산되고 있다. 급속열분해를 통한 바이오오 일은 최초 건조 바이오매스 기준 최대 75 무게%까지 생산할 수 있지만, 일반적으로 60-75% 수준이 적합하다. | |
바이오매스의 에너지 전환기술 중 바이오오일의 장점은? | Fig. 1에서 보는 바와 같이 바이오오일은 바이오매스를 급속 열분해(fast pyrolysis)하여 얻는 액체연료로서 고체 원료에 비하여 에너지 밀도가 높아 운반, 저장 비용이 적게 들 뿐만 아니라 액체이므로 취급이 용이하여 난방용, 발전용 연료로서 이용가치가 높다[14-16]. 미국의 바이오매스 프로그램에서는 이러한 바이오오일을 고품질로 개질하여 최종적으로 수송용 연료인 휘발유나 경유 대체 연료로 사용하는 계획을 수립하고 있기도 하다[17]. |
