화석연료 사용 비중이 큰 농업분야에서는 최근 불안한 국제정제와 맞물린 에너지 가격 상승과 활발한 스마트팜 보급으로 전력사용량까지 증가하는 에너지 사용 패턴 변화로 새로운 국면을 맞고 있다. 따라서 친환경 분산형 전원으로 연료전지를 이용하며, 바이오매스를 직접 연료로 사용할 수 있는 연료전지 열병합발전 시스템은 농가에 열 및 전기에너지를 동시에 공급할 수 있는 효과적인 에너지시스템으로 인식되고 있다. 본 총설 논문에서는 바이오매스, 특히 농업부산물을 연료로 활용하기 위한 연료전지 기반의 열병합발전 시스템에 대한 공정 구성과 기술적 동향을 제시하고, 통합 연계공정 설계 시 고려해야 할 부분들을 논의하고자 한다.

Abstract ▼ AI-Helper

In the agricultural sector where the fossil fuels are primary energy resources, the current global energy crisis together with the dissemination of smart farming has led to the new phase of energy pattern in which the electricity demand is growing faster particularly. Therefore, the fuel cell combined heat and power system, coupling the environmentally friendly fuel cell to biomass treatment and feeding, can be regarded as the most effective energy system in agriculture. In this mini-review, we discuss the R&D trend of the fuel cell combined heat and power system aimed at utilizing agricultural by-products as fuels and highlight the issues in terms of the process configuration and interconnection of individual processes.
