Hi,
We are modeling decarbonization scenarios for ethylene production by considering several low-carbon technologies to reach net-zero emission in 2050. However, we noticed that some technologies with high production costs and lower production efficiency outperform more efficient available technologies. We tried to understand why this happens but unfortunately we could not figure it out. We would be grateful if you can have a look on our case study: https://drive.google.com/file/d/1g_GZnaW...share_link
For the considered net-zero scenario, the model predicts the Biomass-MTO pathway as the dominant technology in 2050, while there are other technologies e.g. WE-MTO which have lower production cost (and higher production efficiency and also lower emission intensity), but the model predicts only minor contributions for them. For example, we tried to deactivate Biomass-MTO pathway to see how other technologies contribute for the production, but we noticed that the model rather implement Dummy technologies (IMP*Z) instead of other available technologies which we are sure can fulfill the demand and emission reduction constraint. Could you please let us know your thoughts on that? Thanks a lot.
