Research frontiers in CO2 shipping and storage
What happens when you meet a nerd? Some of the energetic passion rubs onto you! That’s what happened to us when we were sitting around the table In the UKCCSRC conference at the University of Sheffield. We were discussing CO2 storage and shipping combinations.
The session was led by a scientist from the industry. While the underlying current throughout the conference was how was to commercialise carbon capture technology and will industry accept carbon capture technology, here at the table were industry stalwarts who had seen it all, and done it all! It couldn’t have been a better setting to learn about current state of CO2 shipping and storage!
The discussion started with a good briefing about the role of R&D in shipping and storage of CO2. We were given a good overview of the Norwegian CCS experience which spanned 22 years and achieved 22 Mt of CO2 storage. The Northern lights project for establishing CCS infrastructure was explained. We were able to catch a glimpse of the enormous work put into the northern lights project consisting of shipping, onshore facilities, pipeline, and injection.
After the initial briefing, the discussion turned to the aspect of material selection of CO2 shipping. Our attention was drawn to the need to understand the effect of CO2 on seals and materials of construction. This is because CO2 can mix with any water available to form corrosive carbonic acid. This brought up a discussion on impurities in captured CO2 and thermodynamic models to predict the CO2 mixture properties. Everyone seems to agree that more research work has to be done to increase confidence in the existing models.
Finally the discussion concluded the following frontiers of CO2 shipping and storage:
- Trust building for the design tools in CO2 facilities
- Understanding geological storage, its integrity and consequence of CO2 leakage from geological storage sites
- Upfront investment reduction using innovative concepts
Surely the expertise and experience of the Norwegian industry will have a snow ball effect with more industries coming forward to adopt CCS technologies. That’s what CCS community is all about!Uncategorised
