Carbon Capture and StorageIntroduction
The UK emits more than 500 million tonnes of carbon dioxide every year. The quantity has steadily increased since the start of the industrial revolution (1800’s) and peaked late in the last century. Carbon is emitted into the atmosphere (as carbon dioxide, also called CO2) whenever we burn any fossil fuel. The largest sources are power stations that burn fossil fuels: coal, oil or gas. To prevent the carbon dioxide building up in the atmosphere we can catch the CO2, and store it.

Carbon Capture and StorageWhat is Carbon Capture and Storage (CCS)?Carbon Capture and Storage (CCS) involves capturing CO2, transporting it to a storage site, and injecting it underground so that it is not released into the atmosphere. CCS would allow power plants that run on fossil fuels - particularly coal-fired power stations - to continue operating with vastly reduced emissions. It could also be used to capture and store CO2 from industrial processes that are large point source emitters, such as steel or cement producers.

Carbon Capture and StorageArup’s involvement in CCS
Arup undertake all aspects of economic assessment, planning feasibility, design and development of Carbon Capture and Storage (CCS) and have developed a wide range of skills and experience through projects and research. Arup are one of the leading consultants on the strategic development of CCS infrastructure projects in the UK and Europe and have recently completed a feasibility study for the European Union looking at carbon dioxide (CO2) infrastructure for the whole of Europe.

Our collective experience has been developed in the UK and Europe where the existing use of coal and gas fired power stations in close proximity to the declining North Sea oil and gas fields lends itself to the application of CCS.
Arup are undertaking research and projects on the capture of carbon using mineralisation in rocks and the use of algae for biofuel which feed off CO2.
Carbon Capture and Storage is relatively new to the mainstream energy industry and Arup has been involved with the thinking and development of ideas for over six years.

Carbon Capture and StorageWhat might CCS look like?
Increasing levels of CO2 in the atmosphere are (with other greenhouse gases) contributing to climate change and continued burning of fossil fuels creates additional carbon dioxide.
CCS involves trapping the carbon dioxide at its emission source and transporting it to a storage location (usually deep underground). There are three main techniques for trapping the CO2 from fossil fuel combustion: post-combustion, pre-combustion and oxy-fuel combustion.

In post-combustion the CO2 is separated from the flue gas after the fossil fuel is burned. Separation typically uses a solvent that absorbs carbon dioxide. The solvent is extracted and then heated to release a concentrated stream of CO2.

Carbon Capture and Storage
In pre-combustion, fossil fuel is heated in pure oxygen, to create a mix of carbon monoxide and hydrogen. The carbon monoxide can then be catalytically converted to create additional hydrogen and carbon dioxide. The hydrogen is separated for later combustion leaving concentrated CO2.

Carbon Capture and Storage
In oxy-fuel combustion the fossil fuel is burnt in oxygen rather than air, yielding a flue gas mixture comprising mostly steam and CO2. The CO2 is separated by cooling and compressing the gas stream. In both pre-combustion and oxy-fuel the oxygen is derived from an air separation unit.

After the CO2 is captured, the next step is transporting it to a storage site, probably via a pipeline, although transport by ship may also be an option. Compressors generate the high pressure required to allow efficient movement of the CO2.At the storage location, the CO2 will be injected deep underground. Former oil and gas reservoirs are well suited to store CO2 as they consist of layers of porous rock formations that have trapped oil and gas for years. Another option is to inject gas into existing underground saline aquifers. Clearly the objective is for the CO2 to remain underground indefinitely, so selection of the appropriate geology, injection techniques and subsequent monitoring are crucial.

In practice, CCS can usually capture 90% but not all of the CO2 generated from burning fossil fuel. The technology also significantly increases the capital and operating costs for the fossil fuel burning industry (power stations, refineries, cement works etc). One attraction of post-combustion is that it is easier to retrofit this to existing fossil fuel users.

Carbon Capture and StorageProject Examples
Arup evaluated databases of existing CO2 emitters, and potential geological CO2 storage sites were developed, building on previous studies, including GeoCapacity.
Previous studies failed to recognise that many existing CO2 sources may close or have different characteristics in future due to the introduction of renewable energy and greater energy efficiency. Arup reviewed existing examples and developed 3 new scenarios for both 2030 and 2050. Annual CO2 capture ranged from 50-800 million tonnes. “Blueprints” for the future were developed matching sources to sinks, using hydraulic model optimisation and 2 variants were assessed - one assuming both onshore and offshore underground storage was acceptable and the other with offshore storage only. This flagged a potential investment of up to €20bn by 2050 and the importance of clusters, pipeline dynamics and common specifications.

Europe -wide CO2 Infrastructure Feasibility Study
This vision for CO2 infrastructure aids EC strategic planning, which may lead to the inclusion of CO2 infrastructure in the next revision of the Trans-European Networks Guidelines for Energy (TEN-E), in the Summer of 2011.

Carbon Capture and StorageProject ExampleCCS Site Selection, UK
Arup was commissioned to undertake an assessment of sites for a potential UK demonstration of CCS within the Yorkshire and Humber region.
The proposed facility comprised a 430MW coal gasification process with pre-combustion CO2 capture and sequestration in an offshore reservoir.
Arup developed a combined GIS and matrix screening tool to shortlist sites and CO2 pipeline routes for more detailed feasibility using a combination of client specific and environmental criteria. Key constraints included national designations (planning policy), sites of special scientific interest, scheduled monuments, site factors (availability of land, transport connectivity, and potential coal sources) and process factors (ease of pipeline construction, availability of cooling water, discharges, and COMAH restrictions).

Arup provided advice to the Technology Strategy Board on how to stimulate research and development in CCS and where investment might be targeted to achieve maximum impact. The programme involved presentations to industry leaders and representatives which resulted in a variety of partnerships being developed between industry and academic institutions.
