Update of Hydrogen Modeling: Flexibility Tax and Electrolysis Tax #1612
Conversation
… tax benefit depend, additionally, on the share of electrolysis in total electricity demand based data from the German Langfristszenarien with detailed power system modeling
…used for electrolysis, tax levels are ramped up by a logistic function with increasing share of electrolysis in total electricity demand, vm_shDemSeel, based on the assumption that electrolyzers will not be charged taxes at low levels of deployment due to their balancing benefits for the power system
…ity tax from pm_tau_fe_tax

Thanks, Felix! As we all discussed, let's go ahead with this.

Based on the discussions and plots on mattermost, I approve this. Thanks Felix!

Purpose of this PR
This PR mainly updates our green hydrogen modeling. It extends and reparameterizes the flexibility tax for electrolysis and adds a SE electricity tax on electricity used by electrolysis. The electrolysis technology
elh2
is therefore to be seen as grid electrolysis, which is now noted in the technology description.It addresses several issues relevant to the ongoing validation:
Note: A quick review would be great as this is supposed to feature the next release version and @LaviniaBaumstark wants to start validation runs as soon as possible.
Details:
1.) flexibility tax update
2.) SE electrolysis tax

technology) to capture that electrolysis also needs to pay for grid maintenance / expansion. However, as in the real world it may make sense to (partially) free electrolysis from taxes at low levels of production since, for example, electrolysis provides balancing services to the grid of a high-VRE power system, the tax is low at low shares and only increases at higher shares. The relationsship is assumed to be a logistic curve with its inflection point at 10% electrolysis share in electricity demand, that is, taxes for electrolysis will get quite high once this threshold is crossed.3.)
