Carbon Capture and Storage (CCS)

Carbon (dioxide) Capture and Storage (CCS) is used as a mitigation strategy for addressing the increasing levels of carbon dioxide in the atmosphere. We are working to deliver new approaches, methodologies and tools for the safe and efficient operation of offshore storage sites.

CCS has been identified as a climate change mitigation strategy which can significantly reduce the amount of carbon dioxide emitted to the atmosphere from fossil fuel based power generation and other industrial sources. In the UK and many other countries the best storage reservoirs occur in offshore geological formations several 100s of metres below the sea floor. Assurance that the CO2 remains permanently stored is important from both a climate change and local environmental perspective.

We are conducting research underpinning the environmentally safe and sustainable implementation of CCS by developing strategies and systems for effective monitoring and environmental impact assessment, which will increase confidence in CCS as a viable option for reducing atmospheric carbon dioxide, benefiting a broad range of stakeholders from regulatory bodies, to industry and the wider CCS community.

Our approach combines observations, field experiments, laboratory work and mathematical modelling to gain a better understanding of the behaviour of CO2 in marine systems and how best to detect anomalous events.

Making a difference

Our CCS work has made an international impact on policy, by informing the London Convention on disposal at sea. We work closely with industry and policy makers, to quantify and lower operational risk as well as by proposing cost effective monitoring strategies. With the potential expansion of CCS in forthcoming years, this work has great potential for future application.

PML supports Carbon Capture & Storage recommendations

A major investigation from the Environmental Audit Committee, EAC is urging the government to produce a new strategy on Carbon Capture and Storage, CCS following the cancellation of a pioneering £1bn CCS competition last year, six months before it was due to be awarded.


Detecting sea floor carbon dioxide anomalies

​PML scientists are highlighting a new way of detecting carbon dioxide (CO 2 ) anomalies on the sea floor, and how this can help to monitor Carbon Dioxide Capture and Storage (CCS).


Carbon dioxide capture & storage and the marine environment

Following a novel series of experiments carried out beneath the waters of a Scottish sea loch, a team of scientists led by PML have concluded that small-scale leaks from sub-seabed carbon dioxide storage are likely to have little effect on local marine life.
