In both these regions, like in Scotland, stakeholders have spent several years developing CCS projects and transport infrastructure plans. With the support of European funding associated with the Don Valley Power Project, National Grid Carbon has progressed the plans for an integrated onshore CO2 pipeline network that were originally conceived by Yorkshire Forward with AMEC. The proposed route and design of the pipeline network allows CO2 to be gathered from multiple power and industrial sources. The White Rose oxyfuel CCS project would initially be expected to supply 2-3 MtCO2/yr from a new coal power station. However, conceivably many tens of MtCO2/yr could be captured if multiple sources join the network. National Grid is currently appraising a storage site in the Southern North Sea, although offshore routing to the Central North Sea has not been ruled out, providing an opportunity for Scotland to influence this decision. 33 Scottish Enterprise CCS Hub Study Draft Report Figure 10 LongannetLongannet Power Staon - Host to Scosh Power’s 300MW CCS Project power station – host for Scottish Power’s 300 MWe scale CCS Project proposal Cockenzie Power Station The coal power station at Cockenzie is being replaced a gas power station. In keeping with the CCS Directive, the new power station will be “capture ready”. 3.1.5 Industrial capture sites in Scotland The difficulty and cost of industrial capture retrofit are even harder to predict accurately than the cost of a new build. There are a number of factors that make a retrofit complex, such as the extent of integration to the host plant, reliance of host plant for utilities, number of interfacing process streams, control and instrumentation, power and heat requirements, access, land availability and location, impact on process and occupational safety. 28 Scottish Enterprise CCS Hub Study Draft Report Grangemouth Petrochemical Complex Figure 11 Grangemouth petrochemical complex comprises several large CO2 point sources Complex application of retrofit is typified by the Grangemouth refining and chemicals complex, Figure 11. Here the single site contains not only heat and power provision but also process vents. These vents all have to be routed to a capture plant. However as with all process plant the vent system is critical as in many cases any changes to it may result in the process changing or the safety case for the plant being affected. The main site power plant is actually in the middle of the complex and the process units are arrayed around the site. If retrofit capture is applied then the use of a common facility would be centred adjacent to the power plant. Flue gas streams would be routed across the site, with additional pressure support if needed. This is highly complex and space intensive. Refinery or chemical complexes are diverse processes and the emissions from such sites are from multiple sources. In addition intermittent flaring will always account for some of the annual emissions and this is unlikely to be recoverable. No two refineries are identical as each will use different technologies at various scales depending on the incoming crude and outgoing product profile. The sources of emissions are typically process units, process fired heaters and associated utility supply where fossil fuels are combusted to generate heat (steam) and power for the site. Each unit will have its particular issues such as varying contaminants and concentration levels. 29 IniHally focus will be on Power Sector with Industrial CCS following. There is the potenHal for some quick wins - Industrial sites in Scotland typically less than 10km from potenHal pipeline routes! Innovaon will drive down cost of capture in the long term but in order to drive this we need to act now and work together with Industry and Academia alike.
