Climate policy in the European Union (EU) and Germany changed significantly with the adoption of net-zero emissions targets. A key new development is the growing importance of carbon management. The umbrella term includes not only the capture and storage of CO2 (carbon capture and storage, CCS),...

Carbon dioxide capture and storage (CCS) is considered to be an important option for reducing carbon dioxide (CO2) emissions. However, there are still concerns about its economic viability, especially if the risk of leakage in the storage site is taken into account. We use a real options...

The reduction of greenhouse gas (GHG) emissions, in particular CO2, is a major objective of the German energiewende. There has been broad consensus on this goal for many years now - in contrast to the continuing discussion over the proposed shutdown of Germany’s nuclear power plants. The...

Negative emission technologies will likely be needed to achieve the European Commission's goal of greenhouse gas neutrality by 2050. This article investigates the potential of reducing greenhouse gases in the atmosphere via the DACCS pathway, i.e., to capture CO2 from the ambient air and...

Almost 20 years ago, the first CO capture and storage (CCS) project began injecting CO into a deep geological formation in an offshore aquifer. Relevant science has advanced in areas such as chemical engineering, geophysics, and social psychology. Governments have generously funded...
