I'm running a scenario with a very stringent CO2 cap. Therefore the model comes up with high deployment of CCS techs. However, the amount of stored carbon on an annual level is too large. I want to cap this to a maximum value.
In the model the technologies 'consume' the CO2. I want to add a constraint saying that the maximum amount of 'consumed' CO2 is 100 Mt per year. This is a net amount, not the amount of a single technology.
I tried to work with UC_COMPRD/COMCON/COMNET but it didn't work. Does someone have a solution?
I just tried limiting the consumption of a commodity XCOM by defining a UC constraint with UC_COMCON and UC_RHSRT, and it worked fine. The constraint limited the total annual consumption of commodity XCOM to the amount defined by the UC_RHSRT values.
So, I cannot confirm your findings. Could you thus please explain what you mean by saying that "it didn't work"?

Thanks.
Thanks for the reply Antti.
I tried the same but it's not picking up in BE. Here's how I did it. I didn't use UC_COMCON before so I guess I missed something...
You are defining a coefficient of 150000 for the consumption of CO2 (UC_COMCON=150000).
The constraint you are trying to define thus appears to be: 150000 x Consumption(CO2,t) < RHS(t).
If this is what you want, fine, but you are not defining the RHS value (UC_RHSRT) at all, but only an interpolation option 5 for the (missing) UC_RHSRT value. No constraints will be generated, because you have not defined any RHS value.
UC constraints are generated only when some RHS value has been defined.
Therefore, I suggest that you define some value(s) for the UC_RHSRT(t) constant(s), to get the constraint(s) generated.

I managed to solve the issue, thanks Antti for you insight. In stead of using the UC_COMCON is used the UC_FLO and than it worked.
