STEMM-CCS in the Southern Viking Graben: Follow the progress of our first project expedition
Sub-seabed CO2 storage
Carbon dioxide Capture and Storage (CCS) has been identified as an important mitigation strategy to reduce anthropogenic carbon dioxide (CO2) emissions and thereby combat the rising levels of atmospheric CO2 responsible for global climate change and ocean acidification. CCS is seen as a key contribution to reducing anthropogenic greenhouse gas emissions by 80-95% by 2050 and keeping global temperature increases below 2°C, as outlined in the European Commission’s ‘Roadmap for moving to a competitive low carbon economy in 2050’. In addition, CCS is considered an important strategy to reduce the cost of mitigation measures around the continued use of fossil fuels (IPCC, 2014). For most European nations offshore storage of CO2 in depleted oil and gas reservoirs and saline aquifers is the option of choice.
STEMM-CCS will deliver new insights, guidelines for best practice, and tools for all phases of the CO2 storage cycle at offshore CCS sites. 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
