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 (Kühn 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 algorithms and the software dedicated to simulate the separated and differently coupled thermo-hydro-mechanical/chemical processes during injecting and storing CO2 in the subsurface. In general we distinguish between process- and site-related test cases. Process-related benchmarks deal with the required complexity of process coupling as well as equations of state for fluids and constitutive laws for geologic formations. Site-specific benchmarks represent different geological settings for potential CO2 reservoirs, e.g., depleted gas and oil reservoirs as well as deep saline aquifers. The data basis for benchmarking mainly comes from experimental work in the CLEAN project as well as from literature. The benchmarking systematic is aimed at serving as basis for process studies, experimental design as well as for code inter-comparison purposes not only for numerical tools having used by the CLEAN partners but also for upcoming international benchmarking initiatives as well.
