Power-to-Methanol at Refineries as a Precursor to Green Jet Fuel Production:a Simulation and Assessment Study

摘要

The growing interest in power-to-methanol(PtM)in policy,industry and academia illustrates the need for studies assessing the concept's potential in the context of energy transition.Although there are already studies,which evaluate PtM in a generic way,application-specific analyzes for refineries considering the option of further jet fuel synthesis are lacking.This study provides a unique assessment of the techno-economic feasibility and the environmental impacts of PtM plants at refineries as a precursor to green jet fuel production.The utilization of the flue gas of a single refinery,the Heide refinery,is sufficient for the production of 415,095 t_(McOH)/y.As methanol production via PtM avoids 2.50 kg_(COWeq)/kg compared to conventional methanol,it is favorable in terms of greenhouse gas emissions.However,net production costs are 2.9-4.6 times higher than the market price.Subsequent jet fuel synthesis allows a production of at least 83 kt_(Jet)y on basis of the refinery's flue gas.
