Closes #479.

Changes proposed in this Pull Request

This PR proposes to add H2 Cavern and Tank Storages with their energy capacities and charge / discharge capacities. Optionally, for the DE/GA scenarios, expansion limits are added for these capacities for the expendable cavern storages.

Tasks

• clean H2 storage data
• add H2 storages to the network with correct assumptions
• add existing capacities
• handle expansion and existing capacities in add_brownfield

Workflow

Open issues

• Erroneous expansion limit for NL in 2030, as potential < existing capacities for load and power. We assume a missing 0 based on extrapolation from higher year values.
• Are the units correct? Very low values for FOM and VOM. We assume yes, technology-data assumes both at 0.

Notes

Sanity check of included capacities:

2030

2040
