Abstract
최근 원예분야에서는 다양한 작물의 개발 및 수확량 증대를 위해 통제된 환경에서 이산화탄소 농축을 적용해왔다. 본 연구에서는 지구온난화를 최소화하기 위해, 석탄발전소에서 발생하는 이산화탄소를 원예에 활용하였다. 시료는 토마토, 청호박, 후추, 오이등 총 4종의 식물을 선정하였다. 연구 도입부에서는 CO2 가스의 액화 기술에 대해 설명하였다. 본 연구의 주요목적은 석탄발전소 배기가스 중 CO2 발생과정을 사후연소 이산화탄소 포집 이용 및 저장(CCUS) 기법을 이용하여 조사하고, 농산물 성장률을 고려한 최적의 CO2 농도를 검토하는 것이다. 연구 결과에 따르면, CCUS는 96%의 높은 CO2 추출 효율을 보이며 신뢰할 수 있는 기술임을 입증하였다. 또한, 식물의 잎과 줄기의 성장률이 증가함을 확인하였고 경제적 비용을 고려하여 이러한 연구개발은 지속될 필요성이 있다.|In the recent days, horticulture can use carbon dioxide (CO2) enrichment in controlled environments has been shown to improve the development and yield of a wide range of crops. This study aims to utilize the CO2 gas from coal power plant in horticulture to minimize global warming. Total 4 types of vegetables were selected as samples, namely tomato, green pumpkin, pepper and cucumber. The initial stage of this research understands the liquefaction technique of CO2 gas. The main objectives of this study are to investigate the cultivation process of CO2 from the flue gas of coal power plant using Post-Combustion Carbon Dioxide Capture Utilization and Storage (CCUS) technique and to inspect the most adequate level of CO2 concentration for growth rate of agricultural products. Research findings has proven that CCUS is a reliable technique in facilitating CO2 extraction in horticulture with extraction rate as high as 96%. Although result shows increase in the growth rate of vegetable leaves and stems, continuation of the current study should be developed considering economical factor.
