Funded under the EU Horizon 2020 umbrella, STEMM-CCS is an ambitious Research and Innovation Action on geological CO2 storage that will deliver new insights, guidelines for best practice, and tools for all phases of the CO2 storage cycle at offshore CCS sites. It brings together industry and leading scientific and academic researchers in the field of offshore CCS. The work performed in STEMM-CCS will provide a definitive guide for how to select an offshore site for storage operations, how to undertake a risk assessment, how best to monitor the operations, how to identify and quantify fluxes resulting from any leakage, which is necessary for any type of Emissions Trading Scheme (ETS) and to guide mitigation / remediation action. All of this information will be used to better communicate the case for offshore CCS, with a particular focus on communities directly and indirectly impacted. Specifically, STEMM-CCS will produce new operationally efficient tools and techniques for environmental monitoring as well as CO2 emission monitoring, quantification and assessment. It will generate new knowledge to inform our understanding of the reservoir overburden permeability for CO2 by direct investigation of natural geological and man-made features. It will deliver the first CCS demonstration project level implementation of an effective and efficient ecological baseline, incorporating geochemical and biological variability. It will develop automated novel habitat mapping tools to reduce the necessity for laborious processing of images. These outputs will be tested via a controlled sub-seabed CO2 release demonstration and will be synthesised in a decision support tool providing operators with information for site selection, monitoring system design, site operation and mitigation actions in the event of a leak.
The key objectives of the project are:
To produce new tools and techniques for environmental monitoring as well as CO2 emission monitoring, quantification and assessment
To generate new knowledge of the reservoir overburden by direct investigation of natural geological and manmade features
To deliver the first CCS demonstration project level implementation of an ecological baseline, incorporating geochemical and biological variability
To promote knowledge transfer to industrial and regulatory stakeholders and local and international communities
