Massive carbon dioxide pipeline planned

Plans have been put forward to create a massive pipeline to carry 2M.t of carbon dioxide across the country as part of a carbon capture and storage scheme.

A trio of energy companies — Scottish Power, National Grid and Shell UK — are working together on the pipeline proposal.

National Grid would transport the carbon dioxide captured at ScottishPower’s Longannet power station to St Fergus, Aberdeenshire, where it would be transported offshore to be stored in Shell’s depleted gas field in the North Sea.

The work would include building a new 18km long pipeline from Longannett power station, as well as converting an existing natural gas line which runs from Falkirk to Peterhead.

A National Grid spokeswoman said: “We provide the expertise in the transportation of carbon dioxide gas through a combination of new and existing pipelines.

“The existing 280km pipeline will require a change of use from natural gas to transport carbon dioxide instead.

“Work will begin on the new pipeline in 2014, with the overall aim to deliver a full chain post-combustion carbon capture and storage scheme in 2015.”

National Grid said they have been in discussions with the public for over a year and has just completed its second round of public information days about the pipeline proposals.

  • Storing CO2 under the North Sea could have unfortunate consequences for future generations. That would not be fair to them. Sea water percolates into underlying formations, so a CO2 – H2O interface appears to be unavoidable. It could form carbonic acid, which could lead to increased North Sea acidification. The project should not proceed.
