Thanks for the suggestions. There are a few things I have to ask you to recheck!

@euronion I made the updates, please have a look!

LGTM, just one or two things to double-check (and re-run csv creation).

Just because of the large difference in value and unchanged unit, could you double-check? The new combination of value and unit seems more plausible to me, but then there was a bug in the old CSVs, right?

Yes the ebiofuel investment here was always faulty but we never used it in PyPSA-Eur so I removed it now, together with the VOM for the same reasons. They are better calculated directly in PyPSA-Eur in my mind.

Major unwanted changes here (additional empty columns added). Please clean up.
Also please make sure that GH can render it, currently the format is corrupt.

Why remove the source here? If we change the source / data for methanolisation, we either need to keep the original reference here or also change the assumption. But leaving "Guesstimate" hanging alone is not traceable.

unintentional, seems my editor has been spinning, sorry! Will correct and double check.

No worries, been there myself before, that's why we review. :)
