DISCUSSION: should we include 'geothermal' in the final demand carrier group? #1668

Closed ChaelKruip closed 10 years ago

ChaelKruip commented 10 years ago

In the scope of https://github.com/quintel/etsource/issues/628 I have been automating gquery- and chart generation processes. One of the main goals is to have a definition of final demand carriers that works consistently over all sectors.

The following problem cropped up trying to realise this: geothermal is used left of final demand, e.g. in agriculture:

Omitting this carrier will result in 'missing energy' in final demand charts. I therefore have included geothermal as one of the carriers in the final demand group. A typical generalized final demand chart will look like this:

@jorisberkhout @wmeyers @AlexanderWirtz @Richard-Deuchler do you agree that it is acceptable to include 'geothermal' in final demand charts? Or should we be firm and exclude it (and suffer the consequence of the light-green part of above chart vanishing)?

AlexanderWirtz commented 10 years ago

Fine with me. Instead of 'environmen' we might consider 'ambient' as a grouping.

ChaelKruip commented 10 years ago

I choose 'environment' because also 'solar thermal', 'geothermal' etc. are included. Ambient does not really cover that. Another option would be to explicitly say: 'solar, geothermal and ambient'

Richard-Deuchler commented 10 years ago

I agree that 'geothermal' heat should be part of the final energy demand group. 'Environment' should also comprise the ambient/environmental heat input of Heat Pumps...

What does the 'Monetized heat' represent in the above chart?

What does the 'Monetized heat' represent in the above chart?

This is 'sold heat' from CHPs etc. In the backend this is the steam_hot_water carrier that is also included in the energy balance. Perhaps 'sold heat' is easier to understand?

Richard-Deuchler commented 10 years ago

I am fine with the chart labels in an ETM-context. Heat and electricity demand satisfied by CHPs is reported as 'heat and electricity demand', not as as the corresponding demand for fuel.

However, from the perspective of someone who just filled in the CHP research analysis, it might be confusing. In the CHP analysis, we ask the researcher: "What is the percentage of heat from gas CHPs that is not sold?". From this percentage, we derive the amount of actual heat production, which we then label sold heat in the frontend..... Also, in the documentation, we say: "In the ETM, ... , we want to use physical flows; therefore, we do not distinguish between sold and unsold heat." I guess, we have to live with that and explain it, should somebody raise that question.

Let's close this. Re-open if you don't agree.
