# This list of technologies will replace any occurence of `<Specification>``
# in a variable-definition yaml file

# All fuels that have the attribute "ccs: True" have two sub-categories
# "w/ CCS": with a CO2 capture component
# "w/o CCS": with freely vented CO2 emissions (example "Coal|w/o CCS")
#
# e.g., the power plant capacity "Coal|Supercritical" installed
# is described by three variables:
# - Capacity|Coal|Supercritical
# - Capacity|Coal|Supercritical|w/ CCS
# - Capacity|Coal|Supercritical|w/o CCS

Suggest to use Gas Turbine|Open Cycle

Shouldn't the technology then be called Gas Turbine?
One could then define the <Specification>``Open Cycleand Combined Cycle

Perhaps one could then also define a file specification_types.yaml. Or does the information then get too dispersed? What do you think @sandrinecharousset @erikfilias @danielhuppmann ?

Suggest to use Nuclear|Generation 2 (same for next technologies) and to more clearly explain in the description what generation 2 vs. 3 vs. 4 is (year of development, other technical specifications)

Generation 2 is indeed somehow unspecific, but Nuclear is already covered by the <Fuel>isn't it?

The <Fuel>question is also valid for several other of your comments. My thought is that if we say here Nuclear|Generation 2or Wind|Onshore instead of Generation 2 and Onshore then one might end up with variable names containing Nuclear|Nucelar|Generation 2 and Wind|Wind|Onshoresince we say in the naming convention <Fuel>|<Technology>|<Specification>

@danielhuppmann I am a bit lost understanding the difference between this list and the fuel_type list as there are some duplicates (eg Wind|Onshore, Wind|Offshore you just proposed to add...); What if one list is modified and not consistent with the other?

I see your point @sandrinecharousset.
That's why I had listed Onshoreand Offshore and other technologies without their <Fuel>, to keep the list separated relating to the spaceholders in the naming convention they can fill.
However, amybe in some cases it might be confusing or at least not 100% clear what a technology name relates to.
I'd still lean towards keeping fuels and technologies separated.
