Could you please also update the comment in the line above, i.e. how you changed the calculation?
Where did you find the differing value?

This creates un-capturable NG-emissions for all DRI (also H2) in this form. Okay for the paper, but maybe let's put C&R into a separate process before we merge it to develop?
I may have said something else in the past, but it seems like a bad idea now.

Sounds good. Should we leave this PR open until we add C&R ?

Purpose of this PR
I made some corrections to dri-eaf parameters in process-based steel based on POSTED literature, and also added the additional electricity and heat demand for casting and rolling to eaf (this was already included in the bf-bof route).

Uptake of DRI-NG / DRI-NG-CCS is reduced and replaced by a larger uptake of H2-DRI, and some small amount of BF-BOF-CCS (especially in MEA).
