CHP units in the nomenclature

[felixfrischmuth]

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
