将碳捕获和封存集成到生物质发电厂(BioCCS)可以减少碳排放，但其与自然资源消耗相关的生态性能仍未得到检验。本研究以内蒙古毛乌素生物质直燃电厂为例，以内蒙古毛乌素生物质生物质直燃电厂为例，研究了在电厂中加入螺旋藻CCS的减碳效益和生态效益之间的权衡。生命周期评估(LCA)表明，CCS的组合每年可避免1228公吨(MT)的二氧化碳排放，而能值分析表明，由于螺旋藻的培养需要大量的不可再生资源，因此它恶化了BioCCS系统的生态性能。从生态学的角度来看，BioCCS系统是不可持续的。敏感性分析表明，当60%的设计二氧化碳容量被螺旋藻固定时，添加CCS不会产生碳减排效益，而发电生物质的不足也会显著影响系统的性能，这是BioCCS项目的两个主要障碍。这些结果表明，决策者在开发BioCCS系统时应同时考虑碳减排效益和生态成本。
Integrating carbon capture and storage into biomass power plants (BioCCS) can reduce carbon emissions, but its ecological performance associated with natural resources consumption remains unexamined. Taking a typical BioCCS project – the Maowusu biomass direct-fired power plant with the CCS ofSpirulinacultivation in Inner Mongolia of China – as a case, this study observed the trade-offs between the carbon reduction benefits and ecological performance of adding CCS to the power plant. Life cycle assessment (LCA) revealed that the combination of CCS avoids 1228 metric tons (MT) of CO2emissions annually, while emergy analysis revealed that it deteriorated the ecological performance of the BioCCS system because considerable nonrenewable resources were required bySpirulinacultivation. The BioCCS system is unsustainable in the long run from the ecological point of view. The sensitivity analyses show that there would be no carbon reduction benefits by adding CCS when 60% of designed CO2capacity is fixed bySpirulina, and insufficient biomass for electricity generation also affects system performance significantly, which are two main barriers to the BioCCS project. These results indicate that decision-makers should take into account both the carbon reduction benefits and the ecological costs in the development of BioCCS systems.
