What problems remain to be solved?
In Germany, the underground storage of CO2 in deep geological formations is as yet not covered by either legislation or industrial norms and standards. The legislation is in process, based on a joint draft for a national CCS law developed by the Federal Ministry of Economics and Technology and the Federal Ministry of the Environment, Nature Conservation and Nuclear Safety. To develop CCS “state of the art” norms and standards, BGR has put together a project team who will formulate qualification requirements (e.g. reservoir rock properties, cap rock tightness or long term safety of wells) for storage sites in deep saline aquifers and depleted gas fields. In a second phase, these requirements will be assessed and further developed by a team of experts from industry, research and authorities, lead by the Deutsche Gesellschaft für Geowissenschaften (DGG) and the Deutsche Gesellschaft für Geotechnik (DGGT).
