主 题：Renewable energy e-methanol e-hydrogen green carbon source chemical process flexibility
摘 要：Producing renewable e-methanol from e-hydrogen and diverse carbon sources is an essential way for clean methanol *** this,the technical and economic feasibility of different e-methanols has yet to be thoroughly compared,leaving the most promising pathway to achieve commercialization yet *** paper reports a preliminary analysis of the lifecycle greenhouse gas(GHG)emissions and costs of four renewable e-methanols with different carbon sources:bio-carbon,direct air capture(DAC),fossil fuel carbon capture(FFCC),and *** results indicate that renewable e-methanol costs(4167−10250 CNY/tonne)2−4 times the market rate of grey ***,with the carbon tax and the projected decline in e-H2 costs,blue e-methanol may initially replace diesel in inland navigation,followed by a shift from heavy fuel oil(HFO)to green e-methanol in ocean ***,the e-H2 cost and the availability of green carbon are vital factors affecting cost-effectiveness.A reduction in e-H2 cost from 2.1 CNY/Nm3 to 1.1 CNY/Nm3 resulting from a transition from an annual to a daily scheduling period,could lower e-methanol costs by 1200 to 2100 *** paper also provides an in-depth discussion on the challenges and opportunities associated with the various green carbon sources.
