UK Government – Delivering Carbon Capture & Storage
Louise BarrHead, Outreach and CollaborationOffice of CCS, Department of Energy and Climate Change
Why Does Carbon Capture and Storage Matter?
2
‘With Global population is set to rise from 7 to 9 billion by 2050, world energy demand is expected to increase by 50% over the next 20 years alone’‘Zero Emissions Platform’
‘Unless the rise in average global temperature is kept below 2 degrees C devastating and irreversible climate changes will occur’
‘Today renewables provide 13% of our energy and this could climb to 30% by 2030. Fossil fuels will remain our main source of energy for decades to come.’
‘CCS is an essential part of the portfolio of technologies needed to achieve substantial global emissions reductions’‘International Energy Agency’
‘CCS will provide up to 20% of the reductions we need to make by 2050’‘International Energy Agency’
Why CCS is important…

Tackling Global Climate Change
What is Carbon Capture and Storage?
CAPTURE
We can capture at least 90% of the CO2 emitted by power plants and heavy industry
SAFE TRANSPORT
Liquid CO2 has been transported by pipeline for decades
SAFE STORAGE
Using natural storage mechanisms, CO2 is trapped between 700m and 5,000m underground
CAPTURE
Pre-combustion capture
CO2 is captured before fuel is burned
CAPTURE
Oxyfuel capture
CO2 is captured during fuel combustion
CO2 is captured after fuel has been burned
CAPTURE
Post –combustion capture
TRANSPORT
• CO2 is already transported by pipeline, and also by ship when the distance between the CO2 source and storage is too far
• Widespread deployment of CCS will therefore require a CO2 pipeline network
SAFELY STORING CO2
9
The liquid CO2 is pumped deep underground into one of two types of CO2 storage reservoir (porous rock)
Cap rock
Cap rock
Deep saline aquifer
700m - 3,000m
up to 5,000m
Depleted oil and gas fields
Safety of Stored CO2 Increases Over Time
Residual Trapping
Some of the injected CO2 becomes trapped in the tiny pores of the rocks and simply cannot move, even under pressure
Dissolution Trapping
A portion of the CO2 dissolves into the surrounding salt water
Mineral Trapping
After dissolution, some of the heavy CO2-rich water sinks to the bottom of the reservoir, where over time it may react to form minerals such as those found in limestone.
Why CCS is important for the UK…

Ensuring domestic energy security
Why CCS is a major opportunity for the UK: oil and gas expertise and potential storage locations

• UK is ideally placed for offshore CO₂ storage;
• The estimated CO₂ storage capacity of the UK and its continental shelf ~ 22 GTonnes;
• Approximately 100 years of capacity at UK current rate of emissions.

The UK Government’s Commitment to CCS
Maintaining the focus on Delivery …..Demo 1
• FEED studies continue - expected to complete in spring 2011 - currently considering how best we disseminate this knowledge
• Outcome of the procurement of ‘Demo 1’ expected to be announced in second half of 2011, subject to agreeing terms which are acceptable to the Government and the bidder
• Pending successful selection, operation to start shortly after construction (2014-15)
• 1st demonstration is intended to bring invaluable technical, regulatory and commercial knowledge with an explicit commitment to knowledge transfer
• First stage of a process to enable wide deployment in 2020s
• Demos 2-4 will build on arrangements created to enable demo 1 to succeed
Commercial scale demonstration:Demonstration 1
• Scottish Power are the remaining bidder in the first CCS demonstrator project, subject to due diligence and satisfactory terms;
• Scottish Power Consortium seeking to take forward Longannet demonstration project.
• Scottish Power Consortium which also includes Shell (for the storage) and National Grid (for the transport);
• This demonstration project would be retrofitting around 300 MW post-combustion capture technology; and
• Will be one of the first commercial scale coal fired CCS projects in the world.

Working together and sharing knowledge is key… Knowledge Transfer
• Our aim is to provide key information to facilitate the development of other CCS projects in the UK and internationally
• To deliver this, the Knowledge Transfer from projects is expected to go significantly beyond normal commercial practice
• We will deliver Knowledge Transfer from the E.ON FEED and Scottish Power FEED
• And Knowledge Transfer will be integral to the first demonstrator project
• Knowledge Transfer will feed into the EU Project Network and the Global Carbon Capture and Storage Institute’s (GCCSI) knowledge sharing programme.

Maintaining the Focus on Delivery ….. Demonstrations 2 - 4
• Market sounding process signalled a good appetite of further demonstrators and several well developed proposals
• Also signalled the need to include a demonstration of CCS on gas
• EU launched the New Entrants Reserve funding (NER300 funding) launched on Tuesday 9th November 2010. This will provide funding (some £300m EU ETS allowances) towards some 34 renewables projects and 8 CCS projects in the EU
• The call for proposals for NER300 funding was launched on 9th November 2010, with responses due by 9th February 2011
• Decisions on funding arrangements for demonstrations 2-4 are being considered in the context of the March budget

Challenges to overcome…
• Regulatory
– Regulatory environment for key elements of the CCS chain not yet finalised (particularly relating to the consent for storage facilities and the treatment of liabilities associated with the storage of carbon dioxide)
• Technical
– Challenges in, for example, scaling up of capture technologies, identification, characterisation and operation of storage, integration of the full chain
• Commercial
– Need to develop frameworks that successfully integrate all elements of the chain into a commercially viable entity
• Reform of the electricity market
– Emissions Performance Standard, carbon floor price, capacity guarantees
• Access to finance
– Current economic circumstances, uncertainty over the future shape of the energy markets, challenges and risks associated with ‘first of a kind’ – all make for a difficult environment within which to secure finance
• Public acceptance
OCCS role is to address these challenges to make CCS a reality in the UK
Maintaining the Focus on Delivery … Developing a Roadmap
How much CCS and by when?
20
• Scale of challenge
• Market measures required for commercial deployment
• Demonstration to deployment
Roadmap will:• focus on actions to 2020 to enable
commercial investment decisions in the early 2020s
• look at multiple roll-out scenarios to 2050 and identify longer term issues to be addressed

Industrial CCS
Learning from Demonstration Innovation & R&D
Other activities: International
Global• Research and Development projects: progress under a UK-US MoU on
Energy R&D; working towards launch Phase II of the EU-China Near Zero Emissions Coal (NZEC) project;
• Capacity building: making operational the Carbon Sequestration Leadership Fund (CSLF) capacity building fund
• Global leadership: joint lead with Australia on the Clean Energy Ministerial CCUS Action Group, support for CCS in Cancun (December 2010)
• Knowledge Transfer through the GCCSI
EU• Progressing work under the North Sea Basin Taskforce• Working with European partners through the European Industrial Initiative• New Entrant Reserve • Knowledge Transfer through the EU Project Network
The prize from CCS is potentially enormous…
• CCS will provide up to 20% of the CO2 reductions we need to make by 2050
•Wider deployment of CCS will build on the Demonstration Programme. CCS will be applied to gas fired power plants and industrial sources
•CCS also has the potential to retain or create 70,000 – 100,000 high value jobs in UK
•The CCS sector alone could be worth £1.5-3 billion a year by 2020, rising to 3-6.5 billion a year by 2030
