[Question]: model BECCS in Multi Fuel Usage

[ran1988]

Question

Hello, I have a question regarding MultFuelUsage. Biomass is a special type of fuel, especially when used with CCS. GenX offers the Multi-fuel option, but it seems not to be applicable to co-firing biomass. Specifically, for a generator unit that co-fires coal and biomass with CCS (fuel 1 = coal, fuel 2 = biomass). How do I inform the model that fuel 2 is biomass? The parameter Biomass{0, 1} cannot set the second fuel as biomass.
Looking for your response

Hi Ran,

Thanks for Multi-fuel feature of GenX. Can you try to set Biomass to 0 and use (fuel 1 = coal, fuel 2 = biomass) with CCS? If you think biomass is net zero emissions, please set its emission factor to zero in system/Fuels_data.csv. Please let us know whether it works or not.
