Future improvements node properties table

[marliekeverweij]

Recently we have updated the node properties table, for details have a look at: https://github.com/quintel/etengine/pull/1149

While working on this table, we encountered more things to improve in the future which we couldn't pick up in this project. See the lists below, one for developers work and one for modellers! Please add if you have more ideas:

Modellers:

• Add presentation group for transport technologies. At the moment there is no node properties table for these sliders, see https://github.com/quintel/etmodel/issues/3553
• Add separate group for hybrid heat pumps. At the moment these are included in the heat pump group and this means that the efficiency for the gas boiler is not shown.
• Add separate group for large-scale heaters for district heating and buildings. Now these are part of the households heat technology group, meaning that capacities and costs are shown per unit instead of per MW.
• CCS costs: show costs per tonne CO2 / year instead of per unit
• Better structure the file, many specs are duplicated. We could create a general costs group and use that for several presentation_groups

Developers:

• Land use: improve scaling of km2 / MW as it’s now not precise enough for solar panels for example (@antw)
• Make it possible to show attributes of two different nodes in one table. For example this would be interesting for vehicle-to-grid charging where we would like to show the specs of transport_car_using_electricity and transport_car_flexibility_p2p_electricity. Also, for households heating technologies we would like to show the efficiencies for the hot water and space heating supply!

One issue that could be solved by showing two different nodes is the following:

When I open a new II3050 National governance scenario, the power-to-heat boiler for hybrid heating in the Paper industry is set to 410 MW of installed (heat output) capacity:

However, when I open the node property table the installed (electricity input) capacity is only 165 MW:

This is not related to any conversion losses, because the efficiency is 100%. It is because the hybrid heating slider affects two nodes: one p2h node for hydrogen and one p2h node for natural gas. Only the capacity for natural gas is shown.

Noticed by @Charlottevm the technical and financial properties of the Gas CCGT slider refers to "Timeframes in which this technology typically operates", which is meant for the flexibility section and not for power plants.
