Recently, there have been studies in korea about to reduce global greenhouse gas emissions from a fundamental point of view, as the korean government has been putting focus on reducing GHG emissions, raising up photovoltaic, wind power, hydrogen-oxygen unit fuel cells as national strategic project items among 11 CDM items, to correspond to the united nations framework convention on climate change. Biogas from livestock excrements has been produced mostly in brazil, having many of globally expected projects in the field. Therefore, the mechanisms accomplished in brazil are applied to the domestic models in this study. By using these models, the effective use of biogas is studied, and the methods to reduce the GHG emissions by producing substitute electronic power are carried out. As a part of global warming countermeasures, this study aims to suggest methods to use bio gas from swine manure, one of the big livestock excrements. Besides, the approximate amount of GHG that is reduceable, considering the korean swine industry status at present, is estimated using simulations. The results of the study on biogas use and GHG emission reduction effect by bio gas use are as follows. (1) We processed the study on renewable energy use of biogas using IPCC model and the quantitative result for GHG reduction possibilities was output. As a result of the calculation on the standard of minimum amount of excrements, GHG emission reduction per year was converted into CO2 and the value was 3,771,207ton/year. This is equivalent to 2.3% of GHG emission which was exhausted in korea in 2003 and it means reduction possibilities. (2) Electricity generation caused by renewable energy use by using biogas is 821,250MWh/year and it charges 0.23% of whole generation of korea. Generation profit is approximately 59.7 million won per year. Yearly 895.5 million won of generation profit can be expected for 15 years. (3) The result of estimating Economical efficiency with the result of CDM project and the modeling which this study suggested was shown as table 5. (4) The result of this study on renewable energy use utilizing biogas, it was confirmed that potential value existed. |
