8 Page 7 Background Deteriorating generation margin with major closures only a few years away (sooner in Scotland) and no adequate plans for replacements Focus on large percentage of renewables seems to neglect issues due to intermittency Clean coal and CCS alongside renewables can provide security of supplies and near zero emissions, at no greater cost …..and represent a major economic opportunity for Scotland

9 Page 8 CCS offers an opportunity for economic benefit on the scale of the oil industry Global market for thermal power plant is 1041 Bn $ to 2015, 75% coal Global CCS market will be £100Bn/year Lord Oxburgh (former chairman of Shell) CCS will be an industry as big as the oil industry world wide Scotland is well placed to benefit –Oil and gas industry –Edinburgh and Heriot Watt Universities and BGS Scotland –Consultancies including Mott Macdonald, SKM –Doosan Babcock for power plant boilers and carbon capture

12 Page 11 Global power generation abatement in 2050 (IEA BLUE Map scenario) Page 71, Figure CCS power projects/year (eg 28 x 800MW coal and 52 x 500MW gas) from about 2020

13 Page 12 Implications for Policy - UK and Scotland Consenting process to require all large combustion plant/fossil fuel power plant emitting more than 1Mt CO 2 /yr to be built capture-and-storage-ready Seek international agreement to make CCR mandatory for both coal and gas UK CCS regulations in place by 2010 Three coal and one gas large scale CCS demonstration projects in UK, operational by 2015 (an appropriate share to meet EU, G8 and IEA objectives and maintain a leadership position for UK industry) funded from EU 300M EUAs and auction revenues Develop strong incentives by 2010, in addition to the carbon price, to support a second tranche of CCS projects (to be committed by 2015 and operational by 2020) Development of a strategy to implement CCS on all CCR plants (coal and gas) on fast- track timescales –eg enabling legislation for an EPS of 150g/kwh for all plants (new and CCR) emitting above a tonnage threshold –must also recognise need to retain some older coal and gas power plants on the system to provide back up

14 Page 13 A commensurate ambition for CCS in Scotland Two CCS demonstrations in Scotland by 2015, one coal and one gas 2.4GW advanced supercritical coal with CCS to replace Longannet by GW CCGT/CHP with CCS to replace Peterhead by 2020/5 And one other 1GW plant to replace Torness - to be decided around 2018 Delivers a power generation mix for Scotland that –Would be near- zero emissions by 2025 –Ensures security of supplies (gas issues) and firm power on demand (cf wind intermittency) –Sets an example that other major users of fossil fuels could copy All should use CCS technologies from Scottish companies capable of exploiting the global market and generating economic benefit and employment here on a scale comparable to the oil and gas industry Create many thousands of skilled jobs in construction and operation of CCS plants

15 Page 14 CCS and Renewables in Scotland - an Alternative Scenario Carbon Clean We have modelled the electricity system in Scotland and looked at how to achieve – decarbonisation by 2025 – security of supplies – firm generation in response to demand –and a more economic mix Principles –Sufficient capacity in Scotland to meet peak demand and export clean electricity –Utilise existing grid and power plant sites –Kick-start CCS as a basis for a major new industry in Scotland –Set an example to the world Alternative Scenario Carbon Clean compared to Existing plant mix and the two Scenarios explored by SKM in their report of Nov 2008 for the Scottish Government 2010…… Carbon Clean Scenario…. 2030SKM, 2030 Existing mix

17 Page 16 Intermittency of wind generation – impact has to be recognised SKM report: Combined Scottish wind generation output will be 10% or less for around 20% of the time (ie one in five winters on average will experience wind power levels of 10% or less at times of peak demand) So for one winter in five or one day in five we must completely (90% or more) backup the wind capacity with firm power Turner UKCCC report also recognises that renewables will need full backup by firm power but requires this to be clean And the backup power generation must be able to follow daily variations in demand and balance the wind generation

28 Page 27 Early opportunities for CCS Demonstration – are we ready? UK CCS competition –underway. SP are one of three short listed bidders EU programme for demos funded from 300M EUAs from the new entrant reserve –Call in late 2009 EU proposed economic regeneration package has earmarked 250M euro for UK CCS –Early spend sought if package approved EU voluntary agreement to spend 50% of Auction revenues on climate change mitigation and adaptation RDAs, especially Yorkshire Forward, are developing CCS schemes Conservatives policy statement The low carbon economy – security, stability and green growth proposes to fund –Pipeline networks –5000MW of CCS Demonstration projects –CCS costs for additional coal power plant We need more urgent action within Scotland to prepare for these opportunities

29 Page 28 Tomorrows World How to deliver clean and secure power and set an example of global relevance Doosan Babcock are committed to development and global implementation of cleaner power plants - clean coal, clean gas, nuclear and renewables as rapidly as the market allows We can set an excellent example to other countries which will build fossil fuel power plant if we insist on building all coal and gas plants capture and storage ready in parallel with actions to demonstrate, and then implement, properly regulated and monitored CCS Thank you for your attention
