摘要: 绿色甲醇已被纳入我国新能源鼓励类产业。绿醇燃料是现阶段航运碳减排的主要能源,也是高效的氢载体,利用绿电合成绿醇进行储能,可解决氢存储和运输成本高的难题。概述了绿醇的技术路线及发展现状,分析了绿醇的发展机会与挑战,提出了我国绿色甲醇的发展建议。其中,电制甲醇生产成本主要依赖电价,生物甲醇与电制甲醇耦合的工艺路线将成为降低绿醇生产成本的有效策略。而我国发展绿色甲醇应整合资源优势、立足区位优势,现阶段可重点发展烟气捕集二氧化碳来源的“低碳甲醇”;后续阶段可考虑利用生物源二氧化碳的可能性,将绿醇供应于国际航行船舶加注,逐步替代出口船用燃料,抢占绿色船用燃料的市场份额。

Abstract: Green methanol has been included in China's encouraged industries for new energy. Green methanol as fuel is currently the main energy source for reducing carbon emissions in shipping. It is also an efficient hydrogen carrier, and the use of green electricity to synthesize green methanol for energy storage can solve the probleum of high hydrogen storage and transportation costs. The technical route and development status of green methanol are summarized, based on which, the development opportunities and challenges of green methanol are analyzed, and suggestions for the development of green methanol in China are given. The production cost of electric methanol mainly depends on the electricity price, while the process route of coupling “bio methanol” with “electric methanol” production may become an effective strategy to reduce the production cost. In China, the development of green methanol should integrate resource advantages and focus on location advantages. At the current stage, the focus can be on developing "low-carbon methanol" derived from carbon dioxide captured from flue gas; in subsequent stages, the possibility of utilizing carbon dioxide from biological sources should be gradually considered. Green methanol can be supplied to international shipping vessels for refueling, gradually replace exported marine fuel, so as to capture market share in green marine fuel.
