In the config file was an entry "hydrogen_underground_storage", which wasnt used at all - we use "[sector][hydrogen][underground_storage]". I removed it!

@ekatef I removed an entry in the config file ("hydrogen_underground_storage"), which wasnt used at all as we use "[sector][hydrogen][underground_storage]". Can you review and merge it / also merge it to your config PR? :)

I'm also unsure about the entries gadm_layer_id and gadm_level, but they are both used. @ekatef do you know the difference between those?

Hello @doneachh, that is an amazing idea to clean-up the config! Thanks a lot for addressing hydrogen_underground_storage.

My feeling is that it would facilitate implementation of the modeling approach for the config. The point is we can easily have some side effects from interactions between some config parameters. If you see any way to improve it, that would be very much appreciated.

I'm also unsure about the entries gadm_layer_id and gadm_level, but they are both used. @ekatef do you know the difference between those?

My understanding is that it has been a difference between the power and sector-coupled parts. For now, it looks like a duplication. Feel free to address it 🙂

If you have any other ideas to improve structure of the config, feel free to go ahead and ping me once you'd be satisfied with the result 🙂
