North Sea CO2 storage should be confined to unavoidable emissions due to limited capacity, environmental risks – report

Limited capacity and environmental risks mean that carbon storage in the German North Sea should only be used for residual emissions that remain unavoidable, said researchers from the GEOSTOR consortium of institutes. A number of major challenges must be overcome before CO2 can be injected under the seabed. These include creating regulations, finding measures to prevent potential leakage, and dealing with the noise generated during activities such as site exploration and monitoring, said researcher Klaus Wallmann from GEOMAR Helmholtz Centre for Ocean Research Kiel.
