1 Capture Technology Selection and Deployment UKCCSC Winter School Jan 2012 Jeremy Carey, Technology Manager, SSE

2 Content SSE CCS in SSE Strategy CCPilot100+ R&D Programme Peterhead Technology Selection

3 SSE Background Generation Networks Customers Services Strategy To deliver sustained real growth in the dividend payable to shareholders through the efficient operation of, and investment in, a balanced range of economically-regulated and market-based energy businesses.

4 UK CCS Deployment Drivers CCC 4 th Carbon Budget: Reducing CO2 through the 2020s 300g/kWhr 120Mte CO2 / 400TWhrs 150g/kWhr 60Mte CO2 / 400TWhrs 50g/kWhr 20Mte CO2 / 400TWhrs

5 GB Generation A >60 Mte / year CO 2 overspend (@400TWhrs) Mte CO Nuclear Renewable Coal TWhrs Gas 2030 Carbon Budget

6 Why Flexible CCS? (Or Why not more wind / nuclear?) Poyry: How wind generation could transform gas markets in GB and Ireland, 2010 Weather patterns of January 2000 but with wind penetration of 2030

7 CCS: A low Carbon Wind / Nuclear Enabler Already examples where wind farms have been bid OFF and fossil plant held ON by NG to maintain constrained grid stability 5 th / 6 th April 2011 High rain and wind led to need for downward regulation in Scotland Several Wind Farms bid OFF for several hours 16 th May 2011 Several Wind Farms bid OFF for several hours 2GTs at Peterhead and Longannet U3 held ON at low load at same time 21 st September 2011 Several Scottish Wind Farms bid OFF Several English Fossil Plant Held ON 2GTs at Peterhead held ON at low load An indicator of the critical enabling role of flexible fossil capacity

8 Mapping Technology Deployment Strategic Importance Forest Fires Technology Transfer Bring In-House - No Reinvention! Significant Funding: Collaborate if necessary Camp Fires Sparks Road Map Target key risks Collaborate Seek Funding Tinderbox Which Quadrant should CCS fit into? Outsource R&D Knowledgeable Customer Ventures? Universities Technology Monitoring Build R&D Networks 10 yrs Time to Commercialisation

9 SSE CCS Strategy Overview 1. Engage in collaborative R&D (OxyCoal1&2, CASSEM, CASS-CAP, CO 2 Re-use, storage integrity ) 2. Pilot capture technology at scale CCPilot100+ at Ferrybridge (Coal) 3. Demonstrate full chain on Gas Peterhead CCGT Post Combustion Demo Build company CCS operations know how 4. Be CCS Ready on future CCGT Fleet Be ready to move when the time is right BUT avoid first mover disadvantage

10 First Mover Disadvantage? Biomass Offshore wind Onshore wind Unacceptable Risk Acceptable Risk Marine & Tidal Wall of death Source EPRI

11 CCPilot100+ Driving Innovation

12 CCPilot100+ Project Objectives Confirmation of Performance Comparison with Renfrew Pilot Validation of Design Models Benchmarking DPS Technology vs. Market Steam / Electricity consumption Solvent Consumption UK Capacity Building SSE & Supply Chain Informed Buyer, Informed Operator Regulators, Academics, Wider Stakeholders

13 Core R&D Programme Also includes corrosion coupon extraction and analysis Phase 2 is similar but with a more advanced solvent

20 Why Goldeneye? Sub-surface CO2 storage FEED already complete Most advanced Regulatory engagement on Licence and Permit in Europe >24 million tonnes capacity and excellent injectivity Two good seals and very few legacy wells good for containment Significant expansion potential in the underlying deep saline formation

21 Why Goldeneye? Timing perfect field reached end of gas production in early 2011 Opportunity for re-use of infrastructure that is only 7 years old Normally unmanned good for HSE Dedicated pipeline to shore St Fergus landfall only 10 km from Peterhead A number of partners interested in joining a Storage Joint Venture

27 Consortium Thoughts Consortium Evaluation Consortium Safety Record Consortium Capability to deliver this project in UK. Consortium Capacity and Commitment to deliver Consortium Robustness Delivery track record Consortium Wtd Ave Can they deliver a complex X00mn construction project in the UK? Do they have the skills, people and commitment do deliver our project? Are they recently married? What is the divorce risk? What similar projects have they delivered together?

28 Technology Evaluation Technology Evaluation Relative process safety, wastes and emissions TRL10: 10 plants operating for 10 years Indicative Performance Guarantees Available Design Maturity / Experience / Risk Low CO2 / High O2 Risk Scale up Risk Operability / Flexibility Relative energy penalty Relative solvent and other operating costs Technology Wtd Ave

29 Engineering Evaluation Engineering Evaluation Compliance with Scope Are they going to give us the drawings / data / analysis we asked for? Extent of Process and Equipment Design proposed Extent of Site Integration Design proposed Extent of Construction Planning proposed Engineering Wtd Ave How well is the integration with the existing site thought through. Will we get a generic solution or one designed for the site specific details of Peterhead. Will they give us a credible construction execution plan that can be reviewed for safety etc.

30 Commercial Evaluation Commercial Evaluation Compliance with Schedule PreFEED Price Not the most important at this stage Will they match our desired schedules? Compliance with Terms and Conditions Quality of submission Commercial Wtd Ave Can we afford it? (Threshold) Can we negotiate reasonable terms? What are they signalling about their desire for the project and the way they will approach it?
