Carbon neutrality by 2060 is the recent expression of China's international commitment to reduce its carbon dioxide emissions. Energy and chemical sectors, the two main contributors for carbon dioxide emissions in China, are the biggest bottlenecks for reaching the objective of carbon neutrality. Moreover, coal-to-ammonia production and coal-to-methanol production are the major CO emission process contributors in China's coal chemical sector. Herein, a possible route to the carbon neutral target based on energy-chemical nexus for electricity generation as well as methanol and ammonia production is proposed in this study. The most cost-effective solution for meeting the commitment is identified by considering regional variations in renewable and non-renewable resources and adopting an optimized regional cooperation. According to the roadmap presented in this study, an optimized combination of fossil fuels and renewable energies forming "blue energy economy" is feasible and promising.
到2060年实现碳中和是中国在国际上承诺减少二氧化碳排放的最新体现。能源和化工行业是中国二氧化碳排放的两大主要来源，也是实现碳中和目标的最大瓶颈。此外，煤制氨生产和煤制甲醇生产是中国煤化工行业主要的碳排放过程。在此，本研究提出了一条基于能源-化工关联的发电以及甲醇和氨生产实现碳中和目标的可能途径。通过考虑可再生和不可再生资源的区域差异并采用优化的区域合作，确定了实现该承诺的最具成本效益的解决方案。根据本研究提出的路线图，形成“蓝色能源经济”的化石燃料和可再生能源的优化组合是可行且有前景的。
