CHP units in the nomenclature

Hallo,

I noticed that the topic of CHP power plants is missing in the nomenclature.
The tag_electricity_input_types.yaml includes a bunch of different technologies, which could be extended about CHP units.
E.g. the Gas power plants could be extanded like this:

  • Gas|OCGT:
    description: natural gas (including methane from biomass or hydrogenation)
    in an open-cycle gas turbine (OCGT) power plant
  • Gas|OCGT|w/ CHP:
    description: natural gas (including methane from biomass or hydrogenation)
    in a open-cycle gas turbine (OCGT) power plant with a combined heat and power (CHP) heat extraction unit
  • Gas|OCGT|w/o CHP:
    description: natural gas (including methane from biomass or hydrogenation)
    in a open-cycle gas turbine (OCGT) power plant without a combined heat and power (CHP) heat extraction unit
    This could be done for every gas, biomass, biogas or coal fired power plant.

Before I do a pull request, I wanted to hear about this from you. How to do this the best way?
Because there is the question about CCS. E.g.

  • Gas|OCGT|w/ CCS:
    description: natural gas (including methane from biomass or hydrogenation)
    in an open-cycle gas turbine (OCGT) power plant with a CO2 capture component
  • Gas|OCGT|w/o CCS:
    description: natural gas (including methane from biomass or hydrogenation)
    in an open-cycle gas turbine (OCGT) power plant with freely vented CO2 emissions

Should this be extended as well with CHP? E.g.

  • Gas|OCGT|w/ CHP|w/o CCS:
    description: natural gas (including methane from biomass or hydrogenation)
    in an open-cycle gas turbine (OCGT) power plant with freely vented CO2 emissions and with a combined heat and power (CHP) heat extraction unit

Best,
Felix

Thanks @felixfrischmuth for opening this
I think we should have both
Gas|OCGT|w/ CHP|w/o CCS:
and Gas|OCGT|w/ CHP knowing that Gas|OCGT|w/ CHP=Gas|OCGT|w/ CHP|w/o CCS:+Gas|OCGT|w/ CHP|w/ CCS:
but also keep Gas|OCGT|w/o CCS for cases where the distribution between w/ CHP and w/o CHP is not known (which would also mean that Gas|OCGT|w/o CCS=Gas|OCGT|w/ CHP|w/o CCS:+Gas|OCGT|w/o CHP|w/o CCS
@danielhuppmann what do you think?
(we need to have the segmentation witn/without CHP for CS4)

@sandrinecharousset @danielhuppmann, before I can upload our final data for CS4, we need to update the nomeclature here. We have to decide which is the most consistent way to do this with CHP plants.

@felixfrischmuth we have already defined the CHP units in a PR a few months ago:
see definitions/variable/tag_electricity_input_types.yaml

THis is what is defined:

  • Coal|Lignite|CCGT|w/ CHP:
    description: lignite coal and sub-bituminous coal in a combined-cycle gas turbine (CCGT) power plant, generating Power and Heat
    • Coal|Lignite|CCGT|w/o CHP:
      description: lignite coal and sub-bituminous coal in a combined-cycle gas turbine (CCGT) power plant, not generating Heat
    • Coal|Lignite|OCGT|w/ CHP:
      description: lignite coal and sub-bituminous coal in an open-cycle gas turbine (OCGT) power plant, generating Power and Heat
    • Coal|Lignite|OCGT|w/o CHP:
      description: lignite coal and sub-bituminous coal in an open-cycle gas turbine (OCGT) power plant, not generating Heat
  • Coal|Hard coal|CCGT|w/ CHP:
    description: anthracite and bituminous coal in a combined-cycle gas turbine (CCGT) power plant, generating Power and Heat
    • Coal|Hard coal|CCGT|w/o CHP:
      description: anthracite and bituminous coal in a combined-cycle gas turbine (CCGT) power plant, not generating Heat
    • Coal|Hard coal|OCGT|w/ CHP:
      description: anthracite and bituminous coal in an open-cycle gas turbine (OCGT) power plant, generating Power and Heat
    • Coal|Hard coal|OCGT|w/o CHP:
      description: anthracite and bituminous coal in an open-cycle gas turbine (OCGT) power plant, not generating Heat
  • Gas|OCGT|w/ CHP:
    description: natural gas (including methane from biomass or hydrogenation)
    in an open-cycle gas turbine (OCGT) power plant generating power and heat
  • Gas|OCGT|w/o CHP:
    description: natural gas (including methane from biomass or hydrogenation)
    in an open-cycle gas turbine (OCGT) power plant not generating heat
  • Gas|CCGT|w/ CHP:
    description: natural gas (including methane from biomass or hydrogenation)
    in a combined-cycle gas turbine (CCGT) power plant generating power and heat
  • Gas|CCGT|w/o CHP:
    description: natural gas (including methane from biomass or hydrogenation)
    in a combined-cycle gas turbine (CCGT) power plant not generating heat
  • Hydrogen|OCGT|w/ CHP:
    description: hydrogen used in open cycle gas turbine (OCGT) power plants generating power and heat
    • Hydrogen|CCGT|w/ CHP:
      description: hydrogen used in combined cycle gas turbine (CCGT) power plants generating power and heat
    • Hydrogen|OCGT|w/o CHP:
      description: hydrogen used in open cycle gas turbine (OCGT) power plants not generating heat
    • Hydrogen|CCGT|w/o CHP:
      description: hydrogen used in combined cycle gas turbine (CCGT) power plants not generating heat
