The SPE11 CSP targeting CO2 storage simulations was recently released ( https://www.spe.org/en/csp/ ).
If you are interested in simulating the CSP using OPM Flow you can check out the open framework created by David Landa-Marbán. The framework can be used to setup and run Flow based on the description given in the SPE11 CSP.
