As new small scale LFG (landfill gas) energy project model which can improve economic feasibility limited due to the economy of scale, LFG-Microturbine combined heat and power system with CO<sub>2</sub> fertilization into greenhouses was proposed and investigated including basic design process prior to the system installation at Gwang-ju metro sanitary landfill. The system features CH<sub>4</sub> enrichment for stable microturbine operation, reduction of compressor power consumption and low CO emission, and CO<sub>2</sub> supplement into greenhouse for enhancement plant growth. From many other researches, high CO<sub>2</sub> concentration was found to enhance CO<sub>2</sub> assimilation (also known as photosynthesis reaction) which converts CO<sub>2</sub> and H<sub>2</sub>O to sugar using light energy. For small scale landfills which produce LFG under 3 ㎥/min, among currently available prime movers, microturbine is the most suitable power generation system and its low electric efficiency can be improved with heat recovery. Besides, since its exhaust gas contains very low level of harmful contaminants to plant growth such as NOx, CO and SOx, microturbine exhaust gas is a suitable and economically advantageous CO<sub>2</sub> source for CO<sub>2</sub> fertilization in greenhouse. The LFG-Microturbine combined heat and power generation system with CO<sub>2</sub> fertilization into greenhouse gas to enhance plant growth is technologically and economically feasible and improves economical feasibility compared to other small scale LFG energy project model.
도서지역내 LNG-디젤 혼소엔진을 이용한 발전기 적용성 평가 연구

Until now, diesel generators have been used for electricity generation of Korean Islands. As the price of diesel increases and CO₂ emission regulation is getting stricter, it is limited to use diesel fuel. To use LNG-diesel dual fuel engine as an alternative, economic and environmental analysis was carried out. The results showed that the electricity cost of the dual fuel was 547won/㎾h and that of diesel fuel was 710won/㎾h, and 23% of the electricity cost could be reduced. Also the emission of GHG and harmful exhaust gas could be reduced; by CO₂ 25%, NOx 88%, SOx and PM 99%.
