본 연구과제는 0.5ha 시설채소하우스 냉난방에너지 자립을 목적으로 연구를 추진하였다. 본 과제에서는 가축분뇨와 음식물류 폐기물의 혐기소화를 통해 생산되는 바이오가스를 이용하여 동절기에는 시설채소하우스 가온에너지로 이용하고 하절기에는 냉방에너지로 활용하는 청정에너지 농업시스템을 실증하였으며, 청정에너지 농업시스템의 일최대생산에너지 생산량은 평균 6,071 Mcal/일로서 동절기 하절기 시설채소하우스의 냉난방에너지 자립이 가능하였다 .

Purpose&Contents
■ Establishment of clean energy farming system using the agricultural waste biomass
○ Agricultural use of clean energy, recovery of CO2 and carbon fertilization in greenhouse crop cultivation
○ Establishment of clean energy farming system self-supporting the heating or cooling energy of greenhouse(greenhouse scale 0.5 ha, clean energy supply capacity 3,092 Mcal/day)
Results
○ Clean energy farming is the agricultural activity to improve an efficiency of agricultural energy use and to replace fossil fuels. This study was carried out to establish the clean energy farming system in the controlled cultivation of vegetable crop (cucumber) adopting the biogas production facility. In order to establish the clean energy farming system, the biogas production facility was installed to produce clean energy. And biogas purification system that separate as CO2 and CH4 from biogas was developed and the liquid fertilizer production system using anaerobic digestate was developed for the fertigation of vegetable crop. Lastly, the economical analysis and greenhouse gas mitigation effect were assessed in the demonstration farmhouse adopting the clean energy farming system. The clean energy production for the heating and cooling energy was 6,071 Mcal/day at greenhouse vegetable crop cultivation. Then, volatile solid degradation rate presented 70.2%, and methane yield was obtained as 0.877 Nm3/kg-VSremoved. The economical analysis of the demonstrated farmhouse resulted in the increasing of 3.82 times due to the harvesting time elongation by clean energy use and the biomass increase by CO2 fertilization in the introduction of clean energy farming system. And the break even point showed about 7.2 year. Then, greenhouse gas was assessed to be mitigated to 2,187 ton-CO2/year.
