Shipping MeOH

[toniseibold]

Adding synthetic fuels, biofuels and ft fuels in navigation as meoh demand. However, this seems to be drastic and leads to 100 % meoh shipping in 2045. Not realistic especially considering the current fleet of ships and their lifetime.

sector:
    shipping_methanol_share:
      2020: 0.0966
      2025: 0.1187
      2030: 0.1357
      2035: 0.175
      2040: 0.4558
      2045: 1.0

In the unravel_oilbus() meoh was missing which is needed for industry and shipping. It is following now the same logic as for the oil and added to the boundary condition restricting the import of H2 derivatives (which also missed the import of CH4 on purpose?).

Open discussion @lindnemi

• Import of CH4 added to the boundary condition restricting H2 derivatives import?
• 100 % shipping methanol realistic?

I just use the default values for shipping now @lindnemi

looking good! i updated the submodule to include https://github.com/PyPSA/pypsa-eur/pull/1103

i also added methanol imports to the national co2 constraint. did not do a test run though, if you find the time, maybe @toniseibold you could check that everything works as expected?

Looks good to me
