在"碳达峰"和"碳中和"背景下，如何快速实现碳减排任务重大，其中能源消费结构至关重要。在CO₂循环利用中，甲醇作为"碳载体"和"氢载体"可以促进氢能产业优化，解决氢气（H₂）难运输、难存储的瓶颈。针对富碳天然气和CO₂集中排放大户，充分利用甲醇和H₂之间的相互转化反应，提出富碳天然气-甲醇-氢能一体化技术和CO₂-H₂-甲醇一体化技术，通过CO₂实现H₂与甲醇互补和相互转化的能源终端供应系统，推动能源低碳转型。

Under the background of "emission peak" and "carbon neutrality",it is a major task to achieve carbon dioxide emission reduction quickly,of which energy consumption structure will be crucial.In CO₂ recycling,methanol,as a "carbon carrier" and a "hydrogen carrier" both,can promote the optimization of the hydrogen industry and solve the bottlenecks in transportation and storage of hydrogen.As for carbon rich natural gas and CO₂ centralized emission industries,an integration technology of carbon rich natural gas-methanol-hydrogen and an integration technology of CO₂-hydrogen-methanol are suggested to make full use of mutual conversion reaction between methanol and hydrogen.Low carbon emission energy consumption can be promoted through an energy terminal supply system in which complementary and mutual conversion of hydrogen and methanol is realized through CO₂.
