The UK has the capacity to develop new green industries for capturing harmful carbon dioxide emissions from industry and storing them deep underground, but more investment is needed to further develop the relevant technologies and infrastructure, say scientists in new research published December 7.

The authors, from the Grantham Institute for Climate Change at Imperial College London, have published two briefing papers that highlight the potential opportunities associated with adopting Carbon Capture and Storage (CSS) technologies and the challenges involved. The researchers say developing CCS on a large scale in the UK could promote economic growth, spawning new green technology companies and services that would build and maintain the CCS infrastructure.

CCS technologies are designed to trap and transport carbon dioxide (CO₂) from industry, via pipelines, and store it in offshore underground reservoirs. CCS technology has been used extensively in the oil industry to recover fossil fuels from reserves and trap waste emissions in rock. However, CCS has never been used on a large scale to capture emissions from industry and power plants.

In the briefing papers, the authors say that the UK is in a unique position to develop CCS on a large scale. It has extensive oil industry expertise and a concentration of industries along the coast that are close to depleted offshore oil and gas reservoirs, which can store CO₂.

A large-scale CCS network could be built along the east coast of the UK, suggest the researchers. This would use a pipeline network to carry CO₂ from industries to local storage facilities called hubs, which would pump the gas onwards to offshore to underground reservoirs.

Humberside in the north of England is one place where a CCS network could work effectively, say the authors. Humberside has several existing power stations that emit 60 mega tonnes of CO₂ per year. A pipeline network could pump emissions to hubs based in Humberside and on to underground reservoirs in the Southern North Sea.

However, the authors stress that there are still a number of obstacles to overcome before CCS can play a significant role in helping to mitigate climate change. More research needs to be done to improve current technologies for capturing CO₂ so that they use less energy and are more cost effective to run. The researchers say that the UK government and industry needs to invest more money in research and development, so that rapid improvements can be made to CCS technologies.

Governments will also need to develop credible policies and regulatory frameworks, say the researchers, to assess and manage the economic, health, legal and environmental issues associated with the full-scale use of CCS.

Dr Paul Fennell, one of the briefing paper authors from the Department of Chemical Engineering and Chemical Technology at Imperial College London, says: "The transition to full scale usage of CCS is quite a challenge as we'll need to store several thousand times more CO₂ than we do at the moment for CCS to have a significant impact on our environment. We need to design CCS systems that can cope with holding, transporting and storing these vast CO₂ loads from our industries and power stations."
