Discussion on multi-mode flexible methanol production technology adapted to volatility of renewable electricity
摘要
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 CO2(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 CO2 with renewable electricity-driven water electrolysis for hydrogen production was proposed,establishing 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.关键词
