CO₂ storage capacity in depleted gas fields offshore the Netherlands

TNO-Advisory Group (TNO-AGE) prepared this report for the Dutch Ministry of Climate Policy and Green Growth (KGG). The dual aim of this report is to support policy and decision makers in the emerging CO2 storage industry and to address the EU reporting obligations under the Net Zero Industry Act (NZIA). It provides an initial assessment of the offshore underground CO2 storage capacity in (nearly) depleted gas fields in the Netherlands, which is estimated at a ~1260 to ~1750 Mt (Mega tons) range for practical storage capacity in 46 and 124 storage sites respectively. It includes an examination of the potential development of available storage capacity through time at portfolio level, which is compared to the currently planned transport capacity development.
