Stable Large-scale CO2 Storage in Defiance of an Energy System Based on Renewable Energy – Modelling the Impact of Varying CO2 Injection Rates on Reservoir Behavior

The IPCC Report 2014 strengthens the need for CO2 storage as part of climate change mitigation options. The further expansion of electricity generation by solar and wind and its preferential usage in Germany is leading to strong fluctuations in the CO2 output from former base load coal fired power plants. This study takes a look at the feasibility of large scale industrial CO2 injection into a saline aquifer structure with the main focus on varying injection rates. By means of simulation the influence of the most important parameters is analyzed.
