- Abstract
- In order to make the best choice for CO2 abatement using renewable energy technologies, it is important to be able to adapt these technologies on the basis of their sustainability, which may include a variety of environmental indicators. This study examined the comparative sustainability of renewable technologies in terms of their life cycle CO2 emissions and embodied energy, using life cycle analysis. The models developed were based on case studies of bioenergy pilot plant in P city of Kyungki province. The comparative results showed that a power generation of biogas was associated with 0.96 kWh/m3 biogas and the reduction of CO2 emission was -0.0584 kg of CO2-eq./kg Biomass, other environmental indicator using wood chips was -0.717 kg of CO2-eq./kg Biomass. These indicators applied to gain a complete picture of the technologies studied in the regional area. Final results were total emission of CO2 in P city is 670,041 tCO2, around 500,877 tCO2 for electricity and for heat generation, and 169,164 tCO2-eq. for transportation. When used 1,984 m3/day of waste (pig manure etc.) and operated CHP with wood chips of 144,664 ton/year, the CO2 emission in Pocheonsi was left as is an emission of 449,274 tCO2-eq. and an abatement of CO2-eq. in this region was increased by 32.9%.
