A practical method of carbon emission reduction ratio evaluation for expressway service area considering future infrastructures

Abstract

A practical method of the carbon emission reduction ratio evaluation of expressway service areas considering future infrastructures is proposed to quantify the carbon emission reduction benefits of advanced power technologies. Taking an expressway service area in Guangxi as an example, based on its new infrastructure and low-carbon micro energy network construction scheme, the carbon emission reduction ratio of the service area is calculated and analyzed. The results show that the majority of carbon emissions in the expressway service area are contributed to electric carbon emissions, while little non-electric carbon emission exists, and there is little impact on the results if non-electric carbon emissions are neglected, which can also simplify the calculation process. This evaluation method takes into account both new loads brought by the new infrastructure and the improvement of the overall energy efficiency in the region by the advanced energy conservation and carbon reduction technologies. Emission reduction benefits can be quickly, intuitively and quantitatively achieved with advanced energy technologies such as distributed renewable energy, integrated energy system and AC/DC mixed supply. The error caused by simplified calculation is so small that is applicable to the early stage of project construction, predict and evaluate the carbon reduction benefits of advanced energy technologies to assist the orientation of the project.
