Why Flexible CCS? (Or Why not more wind / nuclear?)

Poyry: “How wind generation could transform gas markets in GB and Ireland”, 2010Weather patterns of January 2000 but with wind penetration of 2030

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

• 5th / 6th April 2011 – High rain and wind led to need for downward regulation in Scotland– Several Wind Farms bid OFF for several hours

• 16th May 2011 – Several Wind Farms bid OFF for several hours– 2GTs at Peterhead and Longannet U3 held ON at low load at same time

• 21st 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

SSE CCS Strategy Overview

1. Engage in collaborative R&D(OxyCoal1&2, CASSEM, CASS-CAP, CO2 Re-use, storage integrity…)

2. Pilot capture technology at scaleCCPilot100+ at Ferrybridge (Coal)

3. Demonstrate full chain on GasPeterhead CCGT Post Combustion DemoBuild company CCS operations know how

4. Be CCS Ready on future CCGT FleetBe ready to move when the time is right…BUT avoid first mover disadvantage

Driving Innovation

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

Core R&D Programme

Also includes corrosion coupon extraction and analysisPhase 2 is similar but with a more advanced solvent

Possible CCPilot100+ Extensions

• CCGT Flue Gas Simulation– Lower CO2 concentration: Capture Performance – Higher O2 concentration: Solvent Degradation

• Inc. Flexibility– Amine Tanks?– Dehydration?– Compression?

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

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

“Consortium Thoughts”

• 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?

• Are they going to give us the drawings / data / analysis we asked for?

• 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.
