为了提高西北地区弃风电的利用率、减少煤化工产业对当地环境的污染，提出了风电与煤化工进行耦合的方案。该方案构建了风电制氢与煤化工相耦合的基本架构，将不能并网的富裕风电电解水制氢，氢气应用于煤化工系统，简化其单元过程。以30万t/a甲醇规模为例，对两种方案的能耗、投资及经济可行性进行了分析。结果表明，在有充足弃风电的西北地区，风电制氢与煤化工耦合系统的煤耗量、水耗量和CO₂排放量分别是原单纯煤化工系统的51.9%、62.2%、22.2%，就地可利用弃风电电量1.238 4×10⁹ kWh/a；对于30万t/a甲醇规模，耦合方案投资可以节省1.23亿元，甲醇成本每年可以减少602.99万元。

In order to improve the utilization rate of wind power generated in China's northwest regions and reduce the pollution of coal chemical industry to local environment there,a coupling scheme of wind power and coal chemical industry is proposed,which establishes the basic framework coupling wind power-hydrogen production with coal chemical industry.Surplus wind power that cannot be received by the grid is utilized to produce hydrogen that can be applied to the coal chemical system to simplify its unit process.Based on a 300,000 t/a methanol scale,the coupling scheme is compared with traditional coal chemical system from energy consumption,investment and economic feasibilities.Results show that coal consumption,water consumption and CO₂ emission of the coupling system are respectively equal to 51.9%,62.2% and 22.2% of those of traditional coal chemical system,and 1.238 4 billion kWh/a of wind power can be consumed locally.As for 300,000 t/a methanol plant,the coupling scheme can save RMB123 million of investment,and the cost of methanol can be reduced by RMB 6.029 6 million per year.
