We get this Error here:

Guess the reason for this error is that we already have the carrier H2 as hydrogen storage:

Will try modelling it without H2 Storage and give an update afterwards.

[doneachh]

Receiving still the same error even without config["extendable_carries"]["Store"] = []

Hello @doneachh :D
Can you share the config?
It seems to me that it is related exactly to that mentioned comment combined (maybe) to the missing re-execution of the subworkflow with the different setting. Could you check?
To check you may start from a clean repo or simply deleting folders resources, networks and results in the subworkflow

[doneachh]

Hello @davide-f :)
restarted it with a clean repo - will give an update here as soon as i get an Error / run was successfull :)

[doneachh]

@davide-f Update: recieved the same error again.

config (is not related to the error in my opinion) like default except:

• countries: ['ET']

config.pypsa-earth (should be not related to the error in my opinion) like default except:

• countries: ["ET"]
• build_natura_raster: true
• ll: ['1.0']
• opts: [Co2L1-144H]
• co2limit: 72.0e+6
• co2base: 72.0e+6
• renewable_carriers: [solar, onwind, hydro]
• Offshore: []
