Names of technologies

[sandrinecharousset]

There is a quite big list of technologies involved in the nomenclature, and there may be some unconsistancies coming from the fact that technologies names come from different sources and horizons.
The objective of this pull request is to define the list of technologies to be used now (knowing that it can evolve in the future), in particular avoid duplication of technologies names.
I also remember a discussion that I cannot find any more aiming at simplifying the yaml files which are becoming very big with lots of variables 'duplicated' per technology. The idea was that instead of having a huge list eg
Capacity|Electricity|techno1 ...., to use Capacity|Electricity| (eg , . Then we would need to maintain lists of technologies for each category.
Would like to have your opinions @erikfilias @danielhuppmann @tburandt and all others of course
I have no idea if this would be compatible with the tools for checking the nomenclature...
List of technos existing now in the nomenclature for power system is:

1/ thermal power
Nuclear
Biomass
Biomass|w/ CCS
Biomass|w/o CCS
Biomass|Traditional (from ehighway)
Biomass|New and imported (from ehighway)
(note that there exist 2 potential segmentations for biomass as namings come from different scenarios)
Coal
Coal|w/ CCS
Coal|w/o CCS
Lignite (from ehighway)
Fossil
Gas
Gas|w/ CCS
Gas|w/o CCS
Gas|Fossil
Gas|Fossil|w/ CCS
Gas|Fossil|w/o CCS
Gas|Biomethane
Gas|Biomethane|w/ CCS
Gas|Biomethane|w/o CCS
Gas|Synthetic Methane
Gas|Synthetic Methane|w/ CCS
Gas|Synthetic Methane|w/o CCS
Oil
Oil|w/ CCS
Oil|w/o CCS

3/ variable renewable
Solar
Solar|CSP
Solar|PV
Wind
Wind|Offshore
Wind|Onshore
Hydro|Run of River

4/ I dont know how to classify
Hydrogen
Geothermal
Non-Biomass Renewables
Ocean
Other

5/ storage
5-1 short term storage
Hydro|Pumped Storage
Energy Storage System

5-2 seasonal storage
Demand response|Load shifting
Demand response|Load curtailement
Hydro|Reservoir

The idea of the classification is to link it with the list of needed variables....
Would appreciate your feedback

[danielhuppmann]

this is a great idea, and it is related to a proposal I made earlier (#29) - I just need a few free days to implement this...

[sandrinecharousset]

Thanks @danielhuppmann , I remembered this but could not find it, sorry for opening yet a new issue!

Hi @sandrinecharousset , @danielhuppmann,

have you by chance already made any progress on this?

When strolling through the repo trying to figure out how to report the capital cost of technologies I landed in this issue.

In the readme in the technology folder it says:

Capital Cost

Variables for the overnight capital cost for new construction of power plants or tranmission lines should follow the structure below.

Capital Cost|<Fuel>|<Specification>
Capital Cost|<Fuel>|<Specification>|<Identifier Of A Specific Power Plant>

Am I right that there is no list of terms that could be used to fill ?

Would be happ to contribute, but perhaps I just missed that there is already some collection of standard technology names?

[sandrinecharousset]

@HauHe In which file did you see this? In technology.yaml, eg you can find Capital Cost|Electricity|, and the list of is here https://github.com/openENTRANCE/nomenclature/blob/master/nomenclature/definitions/variable/fuel_types.yaml
you can also find in the same directory list of , and
Seems to me this was completed but I may be wrong....
(and we still can add new categories to "Fuel" and others......
Best!

[HauHe]

@sandrinecharousset, thanks for your fast response and sorry for my slightly inprecise formulation.
The description of the Capital Cost that I posted above comes from here: https://github.com/openENTRANCE/nomenclature/blob/master/nomenclature/definitions/variable/technology/README.md
What I'm looking for is a list of terms to use for the placeholder <Specification> not the <Fuel>.
I see that in the list you shared there are some technologies like Gas|OCGTdefined, but as the name of the list says it is rather fuel types than technology types. Therefore, I thought that this issue is about creating a yaml file perhaps called technology_types similiar to the fuel_types.
Best,
Hauke

Hi @HauHe , Could you give us a list of "technology types" and potential variables involved, please?
I'll try to take care of it in a PR and check all the remaining variables (and their related technology) if @danielhuppmann and @sandrinecharousset agree.

[HauHe]

Hi @erikfilias, sure I could create a list/draft. Should I already submit as a PR? Then we could build up from that.

[sandrinecharousset]

@HauHe @erikfilias sounds great!

[erikfilias]

Hi @erikfilias, sure I could create a list/draft. Should I already submit as a PR? Then we could build up from that.

I agree; I'll try to care of it asap.

[danielhuppmann]

Thanks @HauHe for putting this issue onto the radar again!

I started a while back to implement a more structured approach to variables using the tags, but didn't have the time to fully incorporate this throughout the definitions.

If either one of you could start a "technology_types" (looking at the power-sector only as a start, I guess?), that would be great!
