Abstract

This perspective paper illustrates that the critical debate regarding geological storage of carbon dioxide has been discursively marginalised in recent years. However, two crucial factors make it reasonable to assume that significant storage-related uncertainties and challenges still exist.

Firstly, experiences of geological storage are primarily related to enhanced oil recovery. Secondly, recent assessments indicate a doubling of the required quantity compared to what was envisioned back in 2005. Therefore, there seems to be a contradiction: as the visions of geological carbon dioxide storage have grown increasingly ambitious, the risks and challenges associated with storage have been marginalised.

The paper suggests geological storage should become a topic of concern for critical social science and concludes with a reflection on five tentative explanations to the discursive marginalisation: 1) Increasing experience and knowledge have resulted in reduced risks; 2) The climate crisis and urgency have supported a broader acceptance of controversial mitigation options; 3) A shifting focus from fossil fuels with CCS to bioenergy with CCS has introduced new and salient problems that make storage-related challenges seem relatively less significant; 4) Coupling CCS to bioenergy has disarmed critics that primarily argue against prolongation of the fossil fuel era, and finally 5) Familiarisation and normalisation processes.
