CHP and CCS in tag_electricity_input_types.yaml

[sandrinecharousset]

For the list of electricity technologies we do have the possibility to describe technologies with CCS or not, and technologies doing CHP or not, but we cannot combine those
I was thinking of proposing something such as
Coal|Hardcoal|w/o CHP|w/o CCS and all variants but the problem is that it may make comparisons difficult with older datasets as well as aggregations.....
For electricity system models being able to do this differenciation may have an impact as the modelling for CHP non CHP plants can be different and the costs are different also...
Has anyone an idea how to do that?
