Context

The possibility of CO2 utilisation should be included in the external model for liquid fuels. This would allow CO2 to be added to the reaction process of synthetic Fischer-Tropsch and methanol synthesis. Through the front end, it will be possible to indicate the amount of CO2 utilised per unit energy of the output.

Implemented changes

Add 3 inputs for CO2 utilisation in:

  • synthetic Fischer-Tropsch: dispensable
  • synthetic Fischer-Tropsch: must-run
  • methanol synthesis

- inputs for co2_utilisation_per_mj now also influence the molecule nodes
- Methanol_synthesis_synthetic_co2 now balances
- If you set the co2_utilisation_per_mj for the methanol synthesis too low, the graph won't break but demand supply may exceed demand. For now, this is considered the responsibility of the user to balance.
The preset demand is not relevant here because the molecule demands follow from the related energy node. Therefore preset demand is even misleading.
