甲醇基绿色碳循环能源化工技术现状与展望
Energy chemical technical maturity review and development prospects of the green & carbon-cycle energy chemical path centered on methanol
以绿氢与捕集CO2为原料合成甲醇,进而生产化学品和燃料的路线有望成为“绿色碳循环能源化工体系”的核心路径之一。参照技术就绪水平(TRL)评估特征梳理了该路径上的绿氢制备、CO2捕集、绿醇合成及下游转化的技术成熟度,并结合政策与经济性研判其发展前景。当前各环节的技术成熟度已具备开展全流程工业示范的条件,但全面商业化仍需降本增效。展望未来,甲醇是衔接可再生能源、能源化工与碳循环经济的关键枢纽,随着绿色甲醇成本下探,以甲醇为中心的绿色碳循环能源化工产业将迎来规模化发展新阶段。
The route of synthesizing green methanol using green hydrogen and captured CO2 as raw materials,and then converting it to produce green chemicals and fuels may become one of the core paths for building the“green & carbon-cycle energy chemical system”.With reference to the evaluation characteristics of Technology Readiness Level (TRL),the technical maturity of the key steps in this path,namely green hydrogen production,CO2 capture,green methanol synthesis,and methanol conversion,is sorted out,and the future development prospects are prospected from the perspectives of policy and economy.Currently,the technical maturity of each step can support the establishment of industrial demonstration projects throughout the entire path,but full commercialization still requires further optimization of technologies and improvement of industrial economy.Looking ahead,methanol is the key bridge connecting renewable energy,energy chemical industry and carbon circular economy.With the foreseeable gradual decline in the cost of green methanol,the green & carbon-cycle energy chemical industry centered on methanol is expected to start large-scale development.
