循环利用对低碳能源系统的价值--以德国能源转型为例
The Value of Recycling for Low-Carbon Energy Systems -- a Case Study of Germany's Energy Transition
摘要：
为了实现气候中和，必须加强循环经济与减少温室气体排放之间的协同作用。以前闲置的资源效率减排潜力将得到利用。由于所有可能的减排措施都通过相互作用联系在一起，因此从成本效益、有效性和遵守气候保护目标的角度评估单一措施非常复杂，需要进行考虑到整个能源系统的基于模型的分析。这项工作提出了德国的能源系统模型，使通过全面的工业流程和实施回收方案的建模，回收措施的影响，在国家温室气体减排战略的背景下，可以分析。情景评估表明，不同的回收策略对德国能源系统有很大的影响。如果没有回收利用，2050年的能源需求将增加300 TWh以上，与参考情景相比，转型成本将增加85%。另一方面，如果能够实现最大的回收率，到2050年，转型成本可以降低26%。回收利用是未来低碳能源系统设计的一项重要且具有成本效益的温室气体减排策略。
英文摘要：
To achieve climate neutrality, synergies between circular economy and reduction of greenhouse gas emissions must be strengthened. Previously idle emission reduction potentials of resource efficiency are to be exploited. Since all potentially possible emission reduction measures are linked by interactions, the evaluation of a single measure in terms of cost efficiency, effectiveness, and compliance with climate protection targets is very complex and requires a model-based analysis that takes the entire energy system into account. This work advances an energy system model for Germany so that through comprehensive modeling of industrial processes and implementation of recycling options, the impact of recycling measures in the context of national greenhouse gas mitigation strategies can be analyzed. The scenario evaluation shows that different recycling strategies have large effects on the German energy system. Without recycling energy demand in 2050 will increase by more than 300 TWh and cost of transformation will rise by 85% compared to a reference scenario. On the other hand, if maximum recycling rates can be achieved, costs of transformation can be reduced by 26% until 2050. Recycling is an essential and cost-efficient greenhouse gas reduction strategy for future low-carbon energy system designs.
