摘要

氢能是可再生电力消纳中应用最广泛的二次能源，但存在“制储输用”难题。当前及未来中长期碳排放格局中，低浓度（体积分数< 20%）二氧化碳排放占总排放的50%以上，是碳减排的关键治理领域。聚焦上述问题，提出将工业低浓度二氧化碳与可再生电力电解水制氢技术协同整合，构建催化反应系统制备绿色甲醇。该路径不仅可利用甲醇作为绿色安全的液态储氢载体，还具有显著的碳减排效益。针对可再生电力波动性与化工生产稳定性之间存在严重时序失配的问题，创新性开发了组合态柔性制甲醇技术：采用模块化架构设计，实现不同工序差异化稳态运行；构建多时间尺度协同优化模型，集成秒级电力波动与小时级化工过程动态响应；开发多目标约束优化算法，平衡碳减排效益与经济性。以东北地区典型风电场为例，通过系统仿真与成本核算，验证了新技术在波动性电力输入条件下的可行性，并量化得到平准化甲醇生产成本为3832.26 CNY/t。本研究可为工业碳源高效转化提供一种技术可行、经济合理的解决方案。

Abstract

Hydrogen energy is the most widely applied secondary energy in renewable electricity consumption

but it faces challenges in “production

storage

transportation and utilization”. In the current and mid- to long-term carbon emission landscape

low-concentration CO

(volume fraction

20%) accounts for more than 50% of total emissions

making it a key area for carbon reduction governance. Focusing on these issues

the synergistic integration of industrial low-concentration CO

with renewable electricity-driven water electrolysis for hydrogen production was proposed

establis

hing a catalytic reaction system for green methanol synthesis. This pathway can not only utilize methanol as a green and safe liquid hydrogen carrier

but also deliver significant carbon reduction benefits. To address the severe temporal mismatch between renewable power volatility and chemical production stability

a multi-mode flexible methanol production technology is innovatively developed: Adopting a modular architecture to achieve differentiated steady-state operation of different processes

constructing a multi-timescale cooperative optimization model that integrates second-level power fluctuations with hour-level chemical process dynamic responses

developing a multi-objective constrained optimization algorithm to balance carbon reduction benefits and economic performance. Taking a typical wind farm in Northeast China as a case study

system simulation and cost analysis verify the feasibility of the proposed technology under fluctuating power input conditions

and the levelized methanol production cost is quantified as 3832.26 CNY/t. The research can provide a technically feasible and economically rational solution for efficient conversion of industrial carbon sources.
