到2060年实现碳中和是中国最近对减少二氧化碳排放的国际承诺的体现。能源和化工行业是中国二氧化碳排放的两个主要来源，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二氧化碳排放的主要过程贡献者。在此，本研究提出了一种基于发电以及甲醇和氨生产的能源-化学关系的碳中和目标的可能途径。通过考虑可再生资源和不可再生资源的区域差异和采取最佳的区域合作，确定了履行承诺的最具成本效益的解决办法。根据本研究提出的路线图，化石燃料和可再生能源的优化组合形成“蓝色能源经济”是可行的和有前景的。研究了甲醇和氨在中国作为能源载体的潜力，建立了区域合作的能源-化学联系优化模型，在气候变化的全球边界下评估了能源资源的绝对可持续性；能源政策;能源工程;能源可持续性;能源系统
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 CO2 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. Roadmap toward carbon neutral supply of electricity, methanol, and ammonia is designed Potential of methanol and ammonia working as energy carriers in China is investigated An energy-chemical nexus optimization model with regional cooperation is developed The absolute sustainability is assessed with planetary boundaries of climate change Energy resources; Energy policy; Energy engineering; Energy sustainability; Energy systems
