CCS Projects

CO2DeepStore is progressing the development of several CCS projects on a co-investment basis, including;

  • CO2 storage for ScottishPower Longannet:
    CO2 storage for ScottishPower Longannet: The Longannet project was shelved on Oct 19th 2011. A joint venture between CO2DeepStore and Shell U.K. Ltd would have provided storage for CO2 from the ScottishPower Longannet project.
  • CO2 storage for SSE Peterhead:
    A storage joint venture between CO2DeepStore and Shell U.K. Ltd to develop a storage site in the Outer Moray Firth area of the North Sea to provide storage for Co2 from SSE’s gas fired power station at Peterhead.
  • East Irish Sea CO2 storage project:
    A storage joint venture between CO2DeepStore and Peel Energy CCS to develop a storage site in the East Irish Sea to provide storage for CO2 emissions in North West England and South West Scotland, including the potential Hunterston project.

Whilst emerging projects are focused on emissions capture from thermal power generation, there are several existing projects related to hydrocarbon production. These are;

CO2 separation from natural gas:

In these projects, the levels of naturally occurring CO2 in the produced gas exceed that allowed in the distribution system. The CO2 is therefore extracted and re-injected.

CO2 injection for enhanced oil recovery:

CO2 can be used to increase oil recovery from some reservoirs. In the US naturally occurring CO2 is often produced for use for enhanced oil recovery (EOR). CO2 from anthropogenic sources can also be used for EOR and in doing so, some of the CO2 remains stored. Current EOR practice seeks to optimise the economics of oil production in a world where there is little value associated with carbon abatement – These are largely ineffective as carbon abatement technologies when the emissions of the product are accounted for. New practices are required to shift EOR into a more effective climate mitigation technology.
