vm_co2capture = vm_co2CCS + v_co2capturevalve and vm_co2CCS = vm_emiTeDetail + vm_ccs_cdr + vm_emiIndCCS

So CO2 captured in industry gets vented. I'm not entirely sure what the purpose of v_co2capturevalve is https://github.com/remindmodel/remind/blob/c67cc61e1ef4d6a36c7dd487bc58e22f51294ae8/core/declarations.gms#L293 but if industry is supposed to supply CO2 for CCU, that should be modelled explicitly.
