摘要
国际航空业要实现2050年净零碳排放的目标,目前唯一现实的能源解决方案是使用可持续航空燃料(SAF).为了判断SAF能否真的实现持续的碳减排,有必要对生产的SAF的可持续性进行评估.本文基于国际航空碳抵消和减排计划(CORSIA)定义的生命周期评价(LCA)方法,考虑了燃料生产过程中副产物的固碳效果对总排放的影响,计算了以某种纤维素类能源植物原料制SAF的三种工艺路径的全生命周期排放值,并进行了数据敏感性分析.结果显示,基于该能源植物的SAF各路径均可实现全生命周期碳减排,且考虑生物炭的固碳效果后最大减排量可达152.2%,对实现净零碳甚至负碳排放有关键作用.
Abstract
The only realistic energy solution for the international aviation industry to achieve its 2050 net-zero carbon emission goal is to use sustainable aviation fuel(SAF).In order to judge whether SAF can really achieve sustainable carbon emission reduction,it is necessary to evaluate the sustainability of the produced SAF.Based on the life cycle assessment(LCA)method defined by the Carbon Offsetting and Reduction Scheme for International Aviation(CORSIA),this paper considers the impact on the carbon sequestration effect of by-products in the fuel production process on the total emissions.The whole life cycle emission values of the three process paths for producing SAF from a cellulose energy plant raw material were calculated,and the data sensitivity analysis was carried out.The results show that all paths of SAF based on this energy plant can achieve carbon emission reduction in the whole life cycle,and the maximum emission reduction can reach 152.2%after considering the carbon fixation effect of Biochar,which plays a key role in achieving net zero carbon or even negative carbon emission.
