Outline of the 2008 BCURA Coal Science Lecture
• Why coal-fired power generation will play a vital role to 2050 and beyond, in the UK and globally.
• The status of coal-fired power-plant technologies, including carbon dioxide capture and storage, which can make coal-fired power very much cleaner, with near-zero emissions.
• The role of the UK industry and research-base in the clean-coal revolution at home and overseas.
• UK and EU policies and actions as governments seek to meet their sometimes conflicting objectives of security-of-supplies, reduction of emissions and affordable energy.
• The lecture will present the case for more coal and less gas in the generation mix, and for cleaner coal, with mandatory carbon capture–ready (CCR) power plant. The case for multiple CCS demonstrations in the UK will be presented.
• And answer the criticisms levelled at those who plan new coal power plant
Page 2
Viewpoint of Doosan Babcock
• The lecture will be presented from the particular point of view of Doosan Babcock, as a UK-based global supplier of coal-fired power plant
• Doosan Babcock has a history of 117 years in power generation – It was at the forefront of the development of pulverised coal-firing and its technology is
used in about one third of the UK coal-fired fleet, including at Drax – the largest and still the newest (first unit commissioned in 1974) coal-fired power station in the country.
• The company has played a major part in improving existing coal power plant – supplying the flue gas desulphurisation system for Drax, over 3000 Low NOx burners,
boosted overfire air NOx reduction for more than 10GW of power plant and now Selective Catalytic Reduction to meet LCPD NOx levels for 2016
• The total company reference list is now 162,000 MW (40,000 MW supercritical !). – Supercritical boilers were first supplied to European customers in the mid 80’s and then to
China from 2001 • Advanced supercritical boilers which give an overall plant efficiency of 46% LHV are
now being offered with full guarantees– with the first order being that from Dong Energy for the Griefsvald Power Plant in Germany
(2x800 MW). Such plant have CO2 emissions 23% below the UK average

Science and Technology base for Doosan Babcock’s business
• Much of the company’s business has resulted from technological developments in anticipation of government requirements and this strategy has been reinforced since Doosan’s acquisition of the company in 2006.
• Doosan Babcock’s business and planning outlook is very dependant on government policies
• We seek to use our experience of introducing new technologies to help the government and its agencies to accelerate the introduction of clean coal technology including CCS as part of a balanced energy portfolio
• “Coal Science” is essential to our business but science alone is not enough, it needs to be followed up with policies and actions by governments and investment in technology, capacity and skills by industry

Doosan Babcock has retained its skills through
•export sales of new boilers,
•construction of plant for others
•boiler services/upgrade work in the UK
•manufacturing capacity in UK, recently enhanced through link to our parent company
•continued investment in R+D
But there are bottlenecks and we are already expanding both capacity and manpower!
We need a basis against which to plan our future investment!!!

Coal + CCS is a lower cost low-carbon option
• Recent evidence to the House of Commons Select Committee on Environmental Audit Committee by EON UK, a major developer of windfarms (onshore and offshore), gas-fired power stations and the proposer of the Kingsnorth clean coal project, quoted the following relative costs-of-electricity generation (£/MWh):
107.0107.0107.0Offshore Wind

• New technology for New-Build claimed attractive because of potential for hydrogen generation and CO2 capture
• Total of 4 units in operation worldwide on coal and some plans for further plants
• Challenges have been poor availability, high cost, lack of flexibility, lack of EPC guarantees
• Latest designs attempt to improve availability with consequences on cost and efficiency
• Main challenge for CCS is the GT (has to fire natural gas, syn gas and hydrogen in turn)
• IGCC projects are being developed in UK, Europe and USA, some with CCS, but few are certain to go ahead. Futuregen on hold.

Amine Oxyfuel IGCC
From joint paper with Jacobs at Powergen 2006
5 -6.2 Euro/kwhfor New build, <5 Euro/kwhfor retrofit
Three options for commercialisation by 2020 :
Numerous studies show these are similar in resulting efficiency and cost of electricity and competitive amongst low carbon technologies
No clear winner but Post Combustion Capture and/or Oxyfuel will be needed for retrofit to plants currently being built around the world (including China and India) – hence BERR choice for its competition
All three capture technologies have been proved in pilot plants but need scale up and demonstration on full-size plants

Furnace Performance Prediction
• PhD project being undertaken by Leeds University, School of Process, Materials and Environmental Engineering.
• Funding from EPSRC, CASE award from Doosan Babcock.• Commenced June 2007.
• To develop a model which predicts the thermal performance of the furnace and pendant surfaces of current-day large fossil-fired utility boilers based on the underlying physical processes.
• Validate the model against plant data.• Extend the model to oxy-fuel firing.
CASE AwardLeeds UniversityCASE AwardLeeds University
ObjectivesObjectives
ApproachApproach
MotivationMotivation • Models used to predict the thermal performance of large fossil-fired utility boiler furnaces have traditionally relied on highly empirical methods, making them unsuitable for future technologies such as oxy-fuel firing.
• Develop intelligent models using Neural Networks (NN) giving accuracy and computational efficiency.
• Generate data sets for both conventional and oxy-fuel firing as input to the NN’s from CFD, purpose made radiation models and plant data where applicable.
• Better understand the underlying science of oxy-fuel firing and develop new radiation models.

ECO-ScrubEnhanced combustion with oxygen and scrubbing
– either no recirculation or partial recirculation of flue gas with replacement of some air by oxygen
• reduces volume of flue gas• enhances CO2 concentration of flue gas
Several potential benefits– potential for net reduction of operating cost due to increased
capture efficiency (opex)– potential for slight reduction in size of post-combustion
capture plant (capex)– reduced-cost retrofit option or potential for savings in new
plant through advanced combustion optimisation and reduced boiler size
– may also be able to reduce size of SCR plant– no issues with air in-leakage

Future R+D
• Support by DTI, BERR, TSB , and the Research Councils has laid a good foundation and we have now the opportunity to build on this
• Need targeted research as above but also require underpinning R+D in cross cutting areas such as coal science, modelling, environmental impact etc
• R+D in Universities also has an important role in creating the skilled people which industry needs for the future and specialist laboratory facilities – EPSRC Doctorate Training initiatives welcome
• EPSRC/EON Strategic Partnership - Call for University proposals, very timely (deadline 6 Nov ) and appropriately targeted
• ETI (autumn), TSB (next year) and BERR ETF(?) expected to call for proposals in this topic area – all will encourage involvement of the Research community in what will be industry- led projects
• Need properly coordinated support for CCS Research and Development, underpinning demonstration projects, bringing together the activities of the Research Councils, Technology Strategy Board, Carbon Trust, Energy Technology Institute and Environmental Transformation Fund
• APGTF will publish its recommendations in January 2009

EU Policies on Energy and Climate Change
• EU energy policy must balance the competing requirements of security, environment and competitiveness (Moscow - Kyoto – Lisbon)
• Sometimes these objectives are compatible, sometimes opposed
• The Spring Council of Ministers 2007 committed Europe to
– At least 20% reduction in greenhouse gases by 2020, and an objective of 30% by 2020, subject to international agreement
– A mandatory target of 20% of energy consumption to be from Renewable sources by 2020 , including a 10% target for biofuels
– Specific plans to be drawn up …. these were published 23 January 2008
Page 67
EU Policies on Energy and Climate – package of 23 Jan 2008
• Strategic Energy Technology Plan (
– CCS is included in the key technical challenges for next ten years to meet 2020 targets, along with renewables
• Communication: Supporting Early Demonstration of Sustainable Power generation from Fossil Fuels
– Crucial need for CCS recognised– Considers options for funding/incentives but offers only modest funding from the
EU for coordination actions described as a “CCS Initiative”– Seeks support from industry
• Proposed Directive: Regulation of Geological Storage of CO2– CO2 captured and stored will be credited as not emitted under the Emissions
Trading Scheme– Options considered included the possibility of making CCS mandatory, but that this
was decided against on cost grounds– Proposes that the LCPD be amended to require all new plants to be capture ready
Page 68
EU Policies on Energy and Climate Change – January package
• Amendment of ETS Directive– Recognises CCS and clarifies that CO2 stored in a regulated site will be treated as
not emitted– All CO2 Allowances to be auctioned from 2013, no free grandfathered allowances -
inherently favours gas vs coal– A proportion of auction revenues (>20%) should be used to reduce GHGs
(including CCS)
• Renewables Directive– A mandatory target of 20% of all energy consumption (power transport and
heating/cooling) to be from Renewable sources by 2020 averaged across EU , including a 10% target for biofuels
– UK target is 15 %, recognising that we have only 1.5% now
Page 69
EU Policies on Energy and Climate Change – current situation
• European Parliament ENVI voted on 7 October 2008 on:– ETS Directive– CCS Directive
• Important outcomes – three Amendments proposed by the rapporteurs were passed– Financing of Demonstration Projects
• Up to a maximum of 500 million allowances (=20Bn euros) in the new entrants reserve shall be awarded to large-scale commercial demonstration projects
• EU or in developing countries and countries with economies in transition outside the EU that ratify the future international agreement.
• EC shall strive to ensure that convincing progress towards letting contracts for theconstruction of 12 large-scale commercial demonstration projects can be displayed before the meeting of the Conference of the Parties to the UNFCCC to be held in Copenhagen in November 2009
– CCS• on compromise amendment 13 of the CCS directive, it was agreed that: “a CO2 stream shall
consist of not less that 95% of carbon dioxide…– Emissions standard for all new power plants
• Member states shall ensure that from 1 January 2015 the operating permit for all electricity-generating large combustion installations with a capacity greater than 300MW granted a construction permit or, in the absence of such a procedure, granted an original operating permit after 1 January 2015 include conditions requiring compliance with an emission performance standard of 500 g CO2/kWh
These decisions will proceed to the full, plenary session of the Parliament and must receive the endorsement of the member states in the Council of the European Union.
Would prevent coal power plants without CCS whilst permitting less than BAT gas power plants !!!!!!!

UK Energy Policies ( as defined in 2007 EWP, 2008 Energy Bill, and 2008 EWP on Nuclear Power)
• Policies aim for a balanced mix of energy sources to be determined by the market
• Renewables support improved by banding of ROCs to boost marine renewables( including offshore wind, wave and tide). Target of 33 GW of offshore wind announced.
• Nuclear to be encouraged by revised consent and planning approvals system (separating generic safety and policy issues from local planning). Also action on nuclear waste and system to require generation companies to set aside funds for decommissioning and waste treatment
• Fossil to be made cleaner, initially by requiring all plants to be built capture ready. CCS to be demonstrated via a government funded programme with the project chosen by a competition
• “Coal Forum to facilitate dialogue within the industry and work to ensure that we have the right framework, consistent with our energy policy goals, to secure the long-term contribution of coal-fired power generation and optimise the use of economical coal reserves in the UK”
Page 72
Carbon Capture Ready (CCR) Consultation
• Issued July, closing date 22 September, report to Ministers to be published by 22 December
• Makes an excellent case for – coal in the generation mix, – for CCS and for capture ready for coal and gas
• Makes very sensible recommendations on the definition of capture ready based on an IEA report
Page 73
What is CCR? Stages of Capture-Readiness
Capture un-ready
(ie CCS not feasible)
Capture ready(ie CCS feasible and recognised in the power plant design with adequate space provided for a feasible capture option and and route for transport of CO2 identified)
Capture and Storage ready(ie CCS feasible and recognised in the power plant design with adequate space provided for a feasible capture option, route for transport of CO2 identified and suitable store identified)
Capture and Storage Qualified (ie CCS feasible and recognised in the power plant design with adequate space provided for a feasible capture option, route for transport of CO2 identified and suitable store qualified)
Capture and Storage ready to implement(ie Capture plant
installed, pipeline built, storage equipment installed)

Capture Ready
Designing a plant (coal or gas) to be CCR will require• Need suitable space for the capture and compression plant, recognising
the area, height and type of plant, …..not to be underestimated• May require safety buffer zones, eg for oxygen or ammonia plant• Will require space inside the power plant for internal connections• Will require additional cooling water• Will require to have a CO2 storage area in mind, compatible with a credible
route for piping CO2
• All above to be demonstrated in feasibility studies prior to sanction of plant
Mandatory requirements for capture readiness will impact on the siting of future power plants, especially CCGTs

Coal Forum – actions during 2008
“The Coal Forum will facilitate dialogue within the industry and work to ensure that we have the right framework, consistent with our energy policy goals, to secure the long-term contribution of coal-fired power generation and optimise the use of economical coal reserves in the UK”
• The Coal Forum’s 2008 report includes – modelling of the UK’s generation mix out to 2025– identification of hurdles and barriers to new clean coal power plant and threats
to existing “Opted-in” plant
• Two Scenarios were modelled -– Look at how to fill generation gap in 2016 and consider two extremes “Optimistic
for Coal” and “Pessimistic for Coal”– Assume 1.6GW nuclear new build in 2018, 2.6GW by 2020 – Assume 25GW of wind in 2020– Nuclear station closures as BERR predictions– Use latest BERR demand predictions– Used EMO logic on derated capacity
Page 78
New clean coal or new gas???
When fitted with CCS, higher cost per tonne of CO2
When fitted with CCS, lower cost per tonne of CO2
May get under the bar of the emissions standard
CO2 is 2x gas so needs twice the EAUs, and may face CO2 emissions standard
Meets 2016 LCPD limits and further tightening possible in 2020
May be harder to meet “Capture- ready”requirements
Sites generally suitable for CCS, can meet “Capture- ready” requirements
OK for CHP, closer to urban areasMore suited to central power plant - out of town
Lower capital cost, shorter planning and build time, shorter pay back time
Higher capital cost, longer planning and build time
Higher and more volatile fuel costs, less secure supplies
Lower fuel cost, plentiful supplies, can be stockpiled cheaply
Gas Power PlantCoal Power Plant
Gas has been the default option
Now 12 GW planned/under construction, most nominally CCR
But at least 7 companies are considering clean coal to balance their portfolios
All recognise that they will need to install CCS
Page 79
Coal Forum Scenarios for UK – “Optimistic for Coal”
Scenario assumes• 6 GW of new capture-ready coal by 2016• 4.6 GW of opted-in plant close in 2016• Three CCS coal demonstration plants by 2018• 6GW of CCS on coal by 2025
Outcomes of model• Generation capacity gap unless a further 2GW of Gas CCGT built by 2012
and 5GW by 2016 on top of 12 GW planned/under construction• 60% dependence on gas during a cold still spell in winter in 2016 (cf 36%
now) • 42% of generation from gas, 16% from renewables in 2016• 33% reduction in CO2 emissions in 2025 vs 2006• Annual coal demand 40 Mt/y in 2016, 45 Mt/y in 2020
Page 80
Coal Forum Scenarios for UK – “Pessimistic for coal”
Scenario assumes• No new coal by 2016• 10 GW of opted-in coal plants close in 2016• No CCS demonstration• All new fossil plant are gas
Outcomes of model• Generation capacity gap unless a further 2GW of Gas CCGT built by 2012
and 15GW by 2016 on top of 12 GW planned/under construction• 75% dependence (GW) on gas during a cold still spell in winter (cf 36%

Ambitions for clean fossil fuel power plant with CCS – role of CCR plant
• IEA “BLUE Scenario” requires 28 coal (800MW) and 52 gas (500MW) CCS power plants per year from 2020
• Timing and scale of introduction of CCS is restricted by the pace of – pilot/demonstration projects – introduction of regulations– validation of CO2 storage sites and – market conditions/incentives …dependent on the carbon price under the ETS
• “Capture ready (CCR)” is therefore very important since new power plants are needed in UK and globally on a scale larger and on a timescale faster than it is feasible to install CCS on even a small proportion
• We conclude that we need multiple CCS demonstrations and all other power plants home and abroad built capture ready
• If we do this in the UK, we will set an excellent global example

A campaign for clean coal
• Recognise that despite energy saving measures we will probably need more clean electricity if carbon targets for heating and transport are to be met
• Recognise that coal and gas cannot be avoided if people are to have sufficient energy and therefore that widespread implementation of CCS is urgent
• Recognise that while CCS technologies do not need to be invented they need progressive scale up, requiring a number of demonstration projects before wholesale implementation
• Seek ambitious programmes for implementation of CCS demonstrations ie Multiple capture technologies, coal and gas
• Question very seriously whether one UK demonstration is sufficient in the context of 20 GW of new fossil plant in the UK (Conservatives are saying they would support at least 3)
• Ensure all other coal and gas plants are genuinely capture-ready and plan retrofit of CCS onto capture ready plant as soon as reasonable - will require incentives or regulation if C-price not sufficient soon enough
• Do not allow politicians to discriminate against coal in favour of gas, such policy simply allows the UK to dodge the carbon issues temporarily, increases security and price risks and sets an example we would not want developing countries to copy

Call for Action to accelerate Clean Coal and Clean Gas
• Consenting process to require all large combustion plant/fossil fuel power plant emitting more than 1Mt CO2/yr to be built capture-and-storage-ready
• UK CCS regulations in place by 2010.• The provision of properly coordinated support for CCS Research and
Development, bringing together the activities of the Research Councils, Technology Strategy Board, Carbon Trust, Energy Technology Institute and Environmental Transformation Fund
• 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 auction revenues or the EU 500
• Development of incentives by 2010 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 that take account of– the progress and performance of demonstration projects;– the carbon price versus costs of CCS;– the capacity of the industry to implement.
