A systematic benchmarking approach for geologic CO2 injection and storage

The idea of this paper is twofold. On one hand, we propose a general systematic for benchmarking of CO2 modelling. On the other hand, we integrate material from the CLEAN project into this framework to demonstrate its applicability (Kuhn et al. in Environ Earth Sci, this issue 2011). Benchmarks are an important instrument to gain a better understanding of interacting physico-chemical processes and they are a necessary tool to verify the...
