DACCS CO2 removal market inquiry

[Aravind-Srinivasachari]

Hello! I need some support in understanding some points with including DACCS technology.

When I run the dac_sspX xml and add an emission/GHG constraint, I see that 3 additional markets CO2 removal and CO2 removal-tfe and airCO2 gets generated with some prices. Could you help me in understanding how I'm supposed to interpret this or why it happens? I see some negative prices also coming with these.

Secondly, if I want to do a ghgpolicy with a different name - should the airCO2 sector, subsector, technology be included for linking or the CO2 removal sector alone with DAC and the technologies be included?

Would appreciate any insights you can give regarding this!
