Electricity and water from renewable hydropower plant are used as input for electrolysis unit to generate hydrogen, while CO₂ is captured from 600 MW supercritical coal power plant using post-combustion chemical solvent based technology. The captured CO₂ and H₂ generated through electrolysis are used to synthesize methanol through catalytic thermo-chemical reaction. The methanol synthesis plant is designed, modeled and simulated using commercial software Aspen Plus^®. The reactor is analyzed for two widely adopted kinetic models known as Graaf model and Vanden-Bossche (VB) model to predict the methanol yield and CO₂ conversion. The results show that the methanol reactor based on Graaf kinetic model produced 0.66 tonne of methanol per tonne of CO₂ utilized which is higher than that of the VB kinetic model where 0.6 tonne of methanol is produced per tonne of CO₂ utilized. The economic analysis reveals that 1.2 billion USD annually is required at the present cost of both H₂ production and CO₂ abatement to utilize continuous emission of 3.2 million tonne of CO₂ annually from 600 MW supercritical coal power unit to synthesize methanol. However, sensitivity analysis indicates that methanol production becomes feasible by adopting anyone of the route such as by increasing methanol production rate, by reducing levelised cost of hydrogen production, by reducing CO₂ mitigation cost or by increasing the current market selling price of methanol and oxygen.

来自可再生水力发电厂的电和水被用作电解装置的输入以产生氢气，同时使用基于燃烧后化学溶剂的技术从600兆瓦超临界燃煤发电厂捕获CO ₂。电解产生的捕获的CO ₂和H ₂用于通过催化热化学反应合成甲醇。甲醇合成装置的设计，建模和仿真使用商业软件阿斯彭加^®。分析该反应器的两种广泛采用的动力学模型，这些模型称为Graaf模型和Vanden-Bossche（VB）模型，以预测甲醇收率和CO ₂转换。结果表明，基于Graaf动力学模型的甲醇反应器每使用一吨CO ₂产生0.66吨甲醇，高于VB动力学模型的VB动力学模型（每使用一吨CO ₂产生0.6吨甲醇）。经济分析表明，以目前H ₂生产和CO ₂减排的成本，每年需要12亿美元，才能利用连续排放320万吨的CO _2。每年从600兆瓦的超临界燃煤电厂合成甲醇。但是，敏感性分析表明，通过采取任何一条途径（例如提高甲醇生产率，降低氢气生产的平准化成本，降低CO ₂减排成本或提高当前甲醇和氧气的市场销售价格）中的任何一条途径，甲醇生产都是可行的。。
