biogas potential overestimated with myopic

[martavp]

There is a bug for the biogas potential, one store with 345TWh is added in every time step, i.e. 'EU biogas-2020', EU biogas-2025' This overestimates the biogas potential. It can be easily fixed by checking if the EU biogas store exits before adding it .

This is also an issue for the solid biomass potential

One quick fix to this issue: PyPSA/pypsa-eur-sec#231 (Set all stores from previous years to zero)

This is only an issue in PyPSA-Eur-Sec 0.6.0 when doing pathway optimization

Can we find out which commit caused this bug? Not to assign blame, but just so we can check there were no further bugs introduced.

I am having a look at the PR and can have a look at the commits as well.

The error was introduced by the new default values (PyPSA release 0.18) where the lifetime has a default value np.inf (previous default np.nan). When filtering which assets should be duplicated for each investment period in function add_build_year_to_new_assets (see here) it does not filter out anymore the biogas/biomass stores.
It should be resolved in PR PyPSA/pypsa-eur-sec#217
