- Abstract
- Carbon-negative electrified production of methanol (e-MeOH) can play a central role in sustainable chemical manufacturing in the coming years. In this context, CO2-based methanol synthesis routes solely based on renewable electricity have been proposed. However, the production route via direct air-captured (DAC) CO2 and green H-2 from water electrolysis (WE) is not industrially available, and in-depth feasibility studies are needed to determine its viability. By designing a 50 kt y(-1) e-MeOH production plant based on DAC-CO2 and electrolytic H-2, we assess the plant's performance and economic feasibility against the state-of-the-art industrial manufacturing based on natural gas steam reforming. Absorption-based DAC accounts for the highest capital expenditure (CAPEX) of the plant, whereas the proton-exchange membrane WE drives electricity consumption. The adiabatic reactor for the catalytic CO2-H-2 reaction is the least cost-intensive section. Thus, the levelized cost of product of e-MeOH in 2050 is expected to be still 3 times that of the current fossil-based MeOH. However, the overall electrified process is carbon negative by consuming 0.64 kg(CO2-eq) kg(MeOH)(-1), whereas the conventional process releases a significant amount of greenhouse gases. Technological improvement of the DAC unit could increase the competitiveness of the e-process, together with lower electricity prices. Furthermore, sourcing CO2 from concentrated streams would cut production costs up to equaling a conventional process penalized with a 183 $ t(CO2)(-1) carbon tax.
