Green, blue, gray hydrogen

Hi Kais!

I see your point. The label "green" is vague here. At the moment this share calculation of v_shGreenH2 serves only to be able to force the model to produce all or large amounts of H2 from electricity. Adapting this, we should make sure that people using the switch c_shGreenH2 can still run scenarios with mostly electrolysis H2. Easiest solution is in my view to create a share of electric (e.g. v_shElH2) and a share of electric+bio H2 and control both by scenario switches.

What is the background of this change? What would you like to do with more categories for hydrogen in the model? Is it about force or constrain electric+biogenic H2 in certain scenarios or calculating other parameters from this? In our reporting we have a finer resolution of hydrogen in the variables SE|Hydrogen|Biomass, SE|Hydrogen|Electricity, SE|Hydrogen|Gas etc.
Best,
Felix
