2.CoalandgaspolicyintheEU2.1. IntroductionEuropean energy systems have entered a period of rapid transition. This transition is driven by technological and policy responses to three major inter-connected challenges: avoiding dangerous climate change; ensuring energy security for the EU; and fostering economic competitiveness in the EU.

Electricity generation based on fossil fuels is currently a significant element of most European energy systems, and for many countries domestic production of lignite, hard coal, and natural gas still contributes to energy independence. In its current form, this method of electricity generation is not consistent with the long-term goals of EU energy policy. Coal- and gas-based power generation will have to undergo the greatest changes as a part of energy transition in the EU, affecting both the technologies used and their roles in the system.

TheEUpolicy framework sets the stage for this transition,both in short and long term. It isthusimportanttotakeintoaccountitscurrentformandlikelyfutureevolutionwhenexploringthe development of novel energy solutions based on fossil fuels. This will ensure that current innovationeffortwillmeetfuturemarketdemand,notonlyintheEU,butalsoglobally.Successfulimplementation of new technologies in Europe provides an opportunity to lead by example anddevelopproductsandexpertisetosellinothermarkets.

This Section presents the EU role in regulating energy sector in the member states. Subsections 2.3and2.4provideanoverviewofcurrent legislative framework in thisareaandanticipatedfuturedynamicsoftheEUpolicyarecoveredinsubsection2.5.TheSectionconcludeswithadiscussiononimplicationsforenergytechnologiesbasedoncoalandgas(subsection2.6).

2.2. Coal and gas-fired plants in the EU energy systemThe EU electricity production is diverse, with a limited share for each type of energy technology, and the dependence on fossil fuels varies significantly by member state.

Page 9: Future Energy Costs: Coal and Gas Technologies

KIC InnoEnergy · Clean Coal and Gas TechnologiesFuture Energy Costs: Coal and Gas Technologies 16 17

While numerous central European countries rely on domestic lignite deposits, natural gas and hardcoal are vital elementsof energymixesacross theEU.Only countrieswitha significanthydropowerpotentialand/orambitiousnuclearenergyprogrammeshavebeensofarabletominimise their reliance on the fossil fuels to produce electricity.

While new energy technologies based on wind and solar energy are being deployed in the EU, so far the issue of supply variability has not been addressed. Thus, there is still a need for flexible back-upplants,whichshouldbe in linewithclimateandenvironmentalobjectivesoftheEUpolicy.

While the EU as a whole imports most of the natural gas and hard coal it uses, the level of energy dependence also varies among the member states. Despite the phase-out of hard coal mininginmostoftheEU(withPolandremainingthebiggestproducer),numerousEuropeancountries such as Germany, the Czech Republic, and Greece rely on their domestic lignite resources. Several member states have enough natural gas deposits to cover a significant partofdomesticdemandorevenexportthefuelabroad(forexample,theNetherlandsandDenmark). Thus, while renewables and energy efficiency are crucial for ensuring energysecurity for the EU as a whole, there is also a rationale for further development of coal and gastechnologieswhichwillallowtouseEuropeanindigenousfossilfuelsinthecost-efficientand sustainable way.

2.3. The EU role in regulating the energy sectorTheLisbonTreaty,whichcameintoforceinDecember2009,introducessharedcompetencein the area of energy policy between the member states and the EU. This means that both the states and the EU institutions have an impact on the regulations shaping the energy sector.Thespecificprovisionsaregiveninarticle194oftheTreatyfortheFunctioningoftheEuropean Union.

The EU’s aims in the energy sector are to:•ensurethefunctioningoftheenergymarket•ensure security of energy supply in the EU•promoteenergyefficiencyandenergysavingandthedevelopmentofnewandrenewable

forms of energy, and•promotetheinterconnectionofenergynetworks.

The Treaty assumes that the member states retain the right to determine their own energy mix. Theunanimous support from the states is required forenvironmentalpolicies affectingdomestic energy use as well as energy taxation. Thus, while the EU institutions have a mandate to pursue the development of single energy market and decarbonisation of the Europeanenergy system, they cannot directly determine the energy choices on national level. In practice, however, the European climate and environment protection legislation is a complex set of rules that significantly limit viable energy options in accordance with the broader sustainable development goals of the EU. Furthermore, the EU has an exclusive competence in the area of competitionprotection.Thismeansthatithasafinalsayonthestateaidrulesandisabletoblockdomestic support schemes in the energy sector if they are seen as harming the competition on theinternalmarket.OtherareasoftheEUintervention–suchasR&Dsupportorcohesionpolicy– may also influence energy sector by redirecting the public funds towards development of preferred elements of the energy mix.

As a result, the EU regulatory framework in the areas of energy, climate, environment andcompetitiondefinetheprospectsfortheenergysectorinEurope,asshowninFigure2.1.Powergeneration from fossil fuels – notably hard coal, lignite, and natural gas – faces the greatest challenges. In order to meet the stringent environmental targets, this part of the energy sector has to transform itself while facing ever more competitive pressure from low-carbon sources.

2.4. Key European regulations affecting coal and gas-fired plants

2.4.1. EU emissions trading schemeTheEUEmissionTradingScheme (EUETS) is a key instrument for achieving the long-termgreenhouse gas (GHG) reduction targets in the EU. By setting an absolute cap on thegreenhousegasesemittedbythesectorscovered(includingpowergeneration)andallowingemitters to trade the resulting limited number of emission allowances, it creates the price signal to reduceGHGemissions.Graduallydecreasing the totalGHG limitby reducing thenumber of available emission allowances each year increases the pressure to lower emissions fromtheenergysectoroverthelongterm.From2013to2020,thecapisreducingby1.74%peryear.From2021onwards,theannualreductionwillriseto2.2%inordertomeetthegoalof40%GHGcutsintheEUby2030.

In the short and medium term, the relevance of EU ETS as a driver of power sector decarbonisation isunclear,due tooversupplyofallowanceson themarket.Thishasdrivendown thecostsofCO

2emissions and weakened the price signal to invest in low-carbon solutions. The EU has

respondedbypursuingstructural reformof thesystem. Itskeyelement– themarketstabilityreserve (MSR)–will startoperating in2019.Eachyear,12%ofallowances incirculationwillberemovedfromthemarkettoMSRifthesurplusofallowancesishigherthanapredefinedlevel(833millionallowances).Whenthesurplusfallsbelow400millionallowances(ortheirpricerisessharply),100millionallowancesaccumulated in theMSRwillbe releasedback to themarketeachyear.Thus,theMSRisaquantity-basedmechanismwhichaimstostabilisethepriceofGHGemissions. It remains to be seen whether and to what extent this goal will be achieved.

EU ETS is also intended to provide a source of funding for low-carbon technologies. Regulations state that at least half of the revenue from national auctions should be used for funding climate changemitigationandadaptationmeasures.Inaddition,after2020,400millionallowanceswillbe used to create an innovation fund, which will support deployment of innovative low-carbon technologies in the energy sector and wider industry. It will operate in a similar way to the currentNER300programme,whichisfocusedonlyonlow-carbonenergygeneration.

EU ETS will finance a modernisation fund, which will support the energy sector transition in member states with relatively low GDP per person. Most of these countries have alreadysecured derogation for their energy sectors, allowing free allocation of allowances to electricity generators in exchange for investments to modernise and reduce carbon emissions. In principle, all these funds may be used for the development and scaling up of technologies for low-carbon production of energy from coal and gas technologies, including carbon capture and storage (CCS)solutions.Thecurrent lowpriceofallowances,however,doesnotprovideanadequatepricesignalforthistechnologydevelopmentasshowninFigure2.2.Thus,whileEUETSreducesincentives for the development of conventional coal- and gas-fired- power plants in the long term, itdoesnotprovide sufficient support for thedevelopmentof cleanalternativesbasedonfossilfuelstoproceedasquicklyasitcould.Theresultisinvestmentuncertaintyandslowerprogress in deployment of technologies including CCS in Europe.

2.4.2. Air qualityEUclimatepolicyisnottheonlydriverofenvironmentalregulationsaffectingtheprospectsofcoal- and gas-based power generation in the EU. Another important factor, especially in short and medium term, is EU legislation related to air quality. The EU Industrial Emissions Directive (IED)setsmandatoryemissionsstandardsforlargeindustrialinstallations,includingpowerplants,asshowninTable2.1.Thestandardsconcerningharmfulsubstancessuchassulphurornitrogenoxides apply to existing installations from January 2016.Numerous derogations give utilitiesenough time to retrofit their power plants according to new rules, however. These include plants that have a limited lifetime and are expected to be decommissioned at the latest by the end of 2023,smallsystemsisolatedfromtheenergynetwork,andplantsfocusedonprovidingusefulheattopublicnetworks.Thederogationsendbetween2020and2023.

TheIEDintroducesthemandatoryuseofbestavailabletechniques(BAT),whichmeanstheones that offer the greatest (currently feasible) reduction of pollutant emissions and theirimpact on the environment. The BATs are defined in BAT reference documents (BREFs),whichwillbecomelegallybindingintheregulatoryframeworksetbytheIED.BATsforlargecombustion plants will be applicable to coal- and gas-powered plants. They are expected not only to tighten the existing standards (such as those for emissions of sulphur andnitrogenoxides),butalsointroducenewstandardsforsubstancespreviouslynotcoveredbyenvironmental regulations. This will result in further retrofit needs for existing power plants, as well as increased investment costs.

Utilities that decide to invest in retrofitting existing coal- and gas-fired power plants face the riskofnot recovering the costsof compliance tonewairquality regulations. This isduetotwokeyfactors.Firstly,revenuesfromthewholesaleelectricitymarketdonotcoverthe fixed costs of conventional plants. While this issue may be eventually addressed by theenergymarketreform,thereisthesecondfactor:unclearpositionofretrofittedpowerplants inthefuturemeritorder(supplycurve)duetopotential increases intheemissionallowance prices and further growth of renewables. The higher the variable costs of coal and gas plants relative to other installations in the system, the lower their capacity utilisation. This, in turn, increases the cost of compliance to emission standards per unit of energy produced.

From the point of view of coal- and gas-based power plants this means that they will have to compete with alternative options for providing securityofsupplyinelectricitymarkets.

2.5. Prospects for EU policy

2.5.1. Climate policy after COP21Since2005andtheestablishmentoftheETS,theEUhasdemonstratedthatitisstronglycommittedtoitsclimategoals.TheCOP21Parisagreementhasreinforcedthiscommitment,signalling that global and EU climate policy will be tightened over time. Although the negotiations that concluded during COP21 took a bottom-up approach (each partydeclaring itsownclimatepolicytargets), theglobalpolicyshift towardsdecarbonisationhas been confirmed. In consequence, calls for upward revision of EU climate and energy targets for 2030 have re-emerged. These calls have been largely ignored so far, as thedebate on climate policy within the EU remains largely driven by the internal discussions on ETS reform.

Thekeyunresolvedquestionconcernstheroleofthesystemintheexpecteddecarbonisationof Europe’s power system and industries. At the same time, the need for technology specific policies for renewable energy systems, energy efficiency, nuclear or clean coal is oftenunderlined. In this context the Paris agreement should be seen as a confirmation rather than an enhancement of European ambitions in the climate protection area. In the future, actions of third parties including the U.S. and China may put additional pressure on Europe to adopt more far-reaching commitments.

The long-term viability of coal- and gas-based electricity generation depends on the technological innovations allowing them to stay in the merit order not only if the EU ETS price significantly increases, but also if even near-100% carbon emissions reductions targets areadopted. While the EU provided funding for pilot CCS projects, low ETS prices and investment uncertainty have resulted in much slower progress than expected in this area. Various measures to increase the pace of CCS development in Europe are considered for the near future, but no actionshavebeenundertakenuptodate.

Ontheotherhand,withouttechnologiessuchasCCS(andotherssuchascarboncaptureandutilisationandCO

2enhancedoil recovery),achieving theEUclimate targets for2050maybe

either costly or technically not feasible, especially if process emissions in industry are takenintoaccount(suchasproducedfromcementorchemicalplants).Thepotential forachieving“negative emissions” from biomass and CCS plants creates opportunities for future research and innovations within this area.

2.5.2. Energy securityWhilethecurrentEUframeworkprioritises renewablesandenergyefficiencyas long-termcontributors to improved energy security, the role of indigenous fossil fuels (includingcoalandshalegas)isalsorecognisedbytheCommission,providedtheiruseisin-linewithclimate goals and environmental standards. There are major technological and geopolitical arguments for their continued use in the European energy system even if the ambitions reduction targets are accepted.

Coal- and gas-fired power plants are still expected to contribute to security of supply, providing necessary flexibility and predictability for the future energy system. This may change if technological alternatives in the form of cost-effective energy storage are developed. It is, however, considered unlikely that thiswill happen on a system-widescalebefore2030.Therefore,theEUhasundertakennumerousstepstowardsincreasinggas supply security, including supporting infrastructure developments, promoting regional approaches to resolving gas supply distortions, and increasing the transparency of intergovernmental agreements in energy. On the other hand, coal supplies areconsidered secure despite the significant dependence of the EU as a whole on imports, thanks to thediversity in thepotential suppliersandhighmarket liquidity.Becauseofthat,domestichardcoalsourcesarenotperceivedbymostoftheparties(includingtheCommissionandmostmemberstates)asasignificantcontributortoenergysecurityforthe continent.

This means that minimisation of energy costs is constrained by reaching other targets. In practice,thisisseenintheEUpreferenceformarket-basedmechanismswhichareexpectedtoallowcost-efficientachievementofsustainable,secureenergysupply.

Two converging processes are visible:1.Developmentofanewenergymarketdesign,and2.DeepeningenergymarketintegrationundertheThirdEnergyPackage.

Thesearebothintendedtoincreasecost-efficientlythesecurityofsupplywithintheEUand–atthe same time – support gradual decarbonisation of the European power system. A consequence oftheseprocessesis likelytobethatcoal-andgas-firedplantswill facemorecompetitionineachmarket,throughexternalenergysupplyandinternallythroughhigherlevelsofrenewableand increased demand response.

At the same time, clean coal technologies and CCS for gas are included in the long-term energy decarbonisation pathways by the EU and other international institutions, such as the InternationalEnergyAgency(IEA).Whilemoreexpensivethanconventionalcoal-andgas-fired power plants, they significantly reduce the costs of the deep decarbonisation policies in the energy sector and therefore remain an attractive alternative option as part of the future power mix. In this context more innovative approaches to the integration of clean coal and gas technologies with renewable generation are required in the longer term to achieve least-costoperationof thewholeenergy system (for example to avoid very lowcapacityutilisationratesatCCSplants).

An important element of EU energy and environmental policy is air quality. Policy focus in this respect isgraduallymoving from industrialemissions (coveredby IED) towardspollutionfrom other sources, such as the transport and residential sectors. In this context, electrification of transport and development of district heating may contribute to air quality improvement, while at the same time increasing demand from the power sector. As such, this offers newopportunities for fossil-fuel-based technologies, provided they are able to reduce theirGHGemissions significantly. This again shows the importance of CCS and other clean coal and gas technologies for their future in the EU energy system.

CHPproductionisoneofthetechnologicaloptions,providingreducedfuelinputsandCO2

emissions.TheuseofCHP ispromotedbytheEnergyEfficiencyDirective,whichrequiresa cost-benefit assessment of CHP introduction whenever there is a potential for suchinvestment (usually when there is new investment or substantial refurbishing of powerplant,industrialfacilityordistrictheatingnetwork).Nevertheless,coal-andgas-basedCHPplantsareunder significant regulatoryandmarketpressure. They facechallenges relatedboth to electricity and heat production, such as low wholesale electricity prices, new emission standards and the need to compete with distributed heat production, which is often not subject to similar climate and environmental standards. Furthermore, in its Heating and Cooling Strategy communicationreleasedinFebruary2016,theEuropeanCommissionfocusesmainlyonrenewables-basedCHP,suchasbiomass-firedorgeothermalinstallations.Nevertheless,therearepotentialsynergiesbetweenCHPandCCStechnologieswhichmayimprove the competitiveness of coal- and gas-fired plants because the unit costs of capture and storageofCO

2.6. Implications for coal and gas-fired energy technology developmentTheEuropeanregulatoryframeworkputspressure inthreewaysonconventionalcoal-andgas-based power plants:

•Increased costs related to climate and other environmental externalities•Limitedpossibilitiesforreceivingstateaid,and•Increasedcompetitiononthesingleenergymarket.

Global climate policy leads in the same direction. After the COP21 Paris summit in 2015, itregained its momentum, casting doubts on the long-term prospects of unabated fossil fuels in theglobalenergymix.Theseprocessesmakeconventionalcoal-andgas-basedpowerplantslargely incompatible with the European and global climate policies in the long-term. Further developmentofrenewablesandenergyefficiencymeasurestogetherwiththeincreaseofETSallowance prices will gradually decrease the capacity utilisation factors of existing and planned conventional coal- and gas-fired plants.

Atthesametime,fossilfuelpowerplantshavedistinctivetechnologicalfeaturesthatmakethemuseful, elements of the modern energy systems. Therefore, the energy transition foreseen by European policy should not be seen as just a threat for fossil fuels, but also an opportunity to redefine the place of coal- and gas-fired plants in the broader energy system.

There is an urgent need for low-carbon innovations, as only affordable, near zero-emissiontechnologiesarelikelytosecuremarketshareforelectricityproductionafter2030.Developingsolutions for near zero-emission fossil fuel plants will significantly decrease the cost of energy transition, stabilizing the energy system and providing much-needed security of supply.

Marketliberalisationandintegrationmeanthatinnovativecoal-andgas-basedsolutionsshouldaddressnotonlytechnical,butalsomarketchallenges,suchaslowcapacityfactorsdrivingupthe average total cost of electricity production. Developing affordable low-carbon optionsfor fossil fuel use is also important from the global perspective. It will contribute to increased ambition of climate policies beyond the EU, which is necessary to meet ambitious goals set by the Paris agreement.

3.Methodology3.1. Scope of modelThe basis of the model is a set of baseline elements of capital expenditure (CAPEX),operational expenditure (OPEX) and annual energy production (AEP) for two differentrepresentative Technology Types under given conditions, impacted by a range of technology innovations. Analysis is carried out at two further points in time (years ofFID),thusdescribingvariouspotentialpathwaysthattheindustrycouldfollow,eachwithan associated progression of LCOE. Themodel has been successfully used in previousprojects delivered by BVGA for KIC InnoEnergy.

While the baselines each represent a relevant current plant, the innovation impact modelling andmoderationprocessresultsinanaverageimpactonLCOEforprojectswithFIDintheyearunder consideration.

There is significant variability in costs between projects, due to both supply chain and technologyeffects,evenwithintheportfolioofagivenpowerplantdeveloper.Assuch,anybaseline represents a wide spectrum of potential costs and it is accepted that there will be actualprojectsinoperationwithLCOEssignificantlyhigherandlowerthanthoseassociatedwith these baselines.

3.3.1. Maximum technical potential impact

Innovations are considered in clusters of similar technologies or impacts. Each of these may affectanumberofdifferentcosts,AEPorlosses,aslistedinTable3.1.Themaximumtechnicalpotential impact on each of these is recorded for each innovation cluster. Where relevant and where possible, this maximum technical impact considers timescales that may be well beyond 2025,thefinalyearofFID.

Frequently, the potential impact of an innovation can be realised in a number of ways, for example through reduced CAPEX or OPEX, or increased AEP. The analysis uses the implementationresultinginthelargestreductionintheLCOE,whichisacombinationofCAPEX,OPEXandAEP.

3.3.2. Commercial readinessIn some cases, the technical potential of a given innovation will not be fully realised, even on a projectwithFIDin2025.Thismaybeforanumberofreasons:

•A long research, development and demonstration period for an innovation•The technical potential can only be realised through a design’s ongoing evolution based on feedbackfromcommercial-scalemanufactureandoperation,or

•The technical potential impact of one innovation is decreased by the subsequent introduction of another innovation.

This commercial readiness is modelled by defining a factor for each innovation specific to each year of FID, defining how much of the technical potential of the innovation is available to projectswithFIDinthatyear. Ifthefigureis100%,thismeansthatthefulltechnicalpotentialis realised by the given year of FID. For some of the innovations modelled, it is anticipated that furtherprogresswillbemadeafterthelastyearofFIDmodelled(2025).

The factor relates to how much of technical potential is commercially ready for deployment in a commercialplantofthescaledefinedinthebaseline,takingintoaccountnotonlytheofferingfor sale of the innovation by the supplier but also the appetite for purchase by the customer.

At this stage, the impact of a given innovation is still captured in terms of its anticipated impact on each cost and operational parameter, as listed in Table 3.1.

These impacts are then applied to the baseline costs and operational parameters to derive the impactofeachinnovationonLCOEforeachTechnologyTypeandyearofFID,usingagenericweightedaveragecostofcapital(WACC).

5. Coal power plant5.a. BaselineThe modelling process described in Section 3 is to:•Define a set of baseline power plants and derive costs, and energy-related parameters for each•For each of a range of innovations, derive the anticipated impact on these same parameters for

each baseline power plant, for a given year, and•Combine the impact of a range of innovations to derive costs, and energy-related parameters

for each of the baseline power plants for each year.

This Section summarises the costs and other parameters for the baseline coal power plants. The baselines were developed by the KIC subject matter experts in coal power systems, and relate to subcritical conventional power plants suitable for retrofitting of technology to improve cost of energy.

Table5.2andFigure5.4showthattheinnovationwiththelargestanticipatedimpactinFID2025is introduction of thermal pre-treatment of biomass and waste-based fuels, which improves the quality of the fuel and allows plants to use greater quantities of biomass and waste-based fuels in place of higher cost fuels.

5.b.2. InnovationsInnovations in fuel handling include physical and thermal treatment of the fuel, blending and the use of additives. A subset of the more important of these has been modelled here.

In addition, innovations for improvements in the physical pre-treatment of fuels were considered. Thesewould increase theLCOE from thebaseline system in this time frame, and soarenotincluded in the overall analysis.

Improvements in fuels through modification and switching

Practice today:Fueladditivesareused,butarelimitedtobasicmineralssuchaskaolinitethatare targeted at reducing slagging and fouling. Fuel blending is practised, but limited to fuels that are not classified as waste.Innovation: This innovation covers two areas:•The use of advanced mineral or artificial additives which reduce ash deposition and influence emissions

such as oxides of nitrogen and mercury, while also reducing high-temperature corrosion, and•Blendingoflowqualityfuels(includingthoseclassifiedaswastes)withprimaryfuelsuptofull

replacement.Commercial readiness:80%ofthebenefitoftheseinnovationsisrealisablein2016,with100%realisableby2020onwards.

Market share:Itisanticipatedthatthisinnovationwillbeimplementedononly40%ofplantsin2025,becauseoflimitationsinapplicabilityduetovariationsinlocalpolicyandregulations.

Introduction of thermal pre-treatment of biomass and waste-based5 fuels

Practice today: In the limited proportion of applications using biomass and waste-based fuels, these are are used without torrefaction or gasification.Innovation: This innovation covers two areas:•Thermal pre-treatment in the form of torrefaction which upgrades the properties of biomass

and biomass-derived waste fuels. This increases energy density, reduces fuel preparation costs (grinding),reducestransportationcostsandincreasestheamountsthatcanbeused(whichalsoreducesemissionscost),butincreasesprocessingcosts;and•Gasification, which reduces pollutant emissions when using some solid fuels containing harmful elements such as trace heavy elements and corrosion-inducers (potassium andchlorine).Someof theseharmfulelementsare retained in thegasifier rather thanpassingthrough to the power plant, so that emissions costs are reduced and the gas produced is easier to use than the solid fuel.

Introduction of hybrid fuel combustion

Practice today: Conventional coal combustion plants use a single combustion chamber with air injected at multiple levels.Innovation: The innovation is to produce an integrated boiler with innovations such as multiple fuel feeds, combustion chambers and reactors that enable the burning of coal alongside low grade fuels, wastes and biomass.Commercial readiness:40%ofthebenefitoftheseinnovationsisrealisablein2016,with80%realisableby2020and100%by2025.Themostcost-effectivecombustiontechnologywilltakethis long to develop.Market share:Itisanticipatedthatthisinnovationwillbeimplementedon30%ofplantin2025,themarketbeinglimitedduetovariationsinplantpreferencesandavailabilityofsuitablefuels.

5.d.2. InnovationsInnovations in the steam and electrical system include steam circuit and turbine flow improvements to materials, waste heat recovery and the electrical system. A subset of the more important of these has been modelled here.

Improvements in steam circuit design

Practice today: Current steam circuits are usually equipped with several steps of high and low pressure heat exchangers and a steam reheating system.Innovation: This innovation covers improved interconnection between stages, which increases heat transfer to useful parts of the cycle. It also includes additional heat recovery processes suchasorganicRankinecyclesystemsandheatpumps,aswellasheatstorageandimprovedprocesses for reheating of steam and preheating of feedwater.Commercial readiness: 50%ofthebenefitoftheseinnovationsisrealisablein2016,with100%realisableby2020.Themainbarrierislimitedexperienceoftheintegrationofthesesystems.Market share:Itisanticipatedthatthisinnovationwillbeimplementedon20%ofplantsin2025.Thelimitationistherelativelyhighcapitalcostforthebenefitsdelivered,makingitattractiveforonly a minority of plants.

Improvements in materials in the boiler and steam circuit

Practice today: Power plants operating with ultra-supercritical steam conditions use advanced steel, but material failures are frequently reported. When existing plants are modernised (includingchanging thesuperheater tubes in theboiler), this isgenerallydonewithout increasing outlet steam temperature and pressure. Corrosion can also be a problem for conventional power plants, especially with furnaces operated for low-emissions and when biomass is co-fired.Innovation: This innovation covers the application of new steel alloys for high temperature, highpressureconditionsandcoatings forwater-walls (evaporators). Thesewillenablehigherefficiencythroughhigheroutletsteamtemperatureandpressurefromthesuperheater,aswellas reduced failure costs. Commercial readiness: 10%ofthebenefitoftheseinnovationsisrealisablein2016,with50%realisableby2020and80%by2025,asnewsteelalloydevelopmentanddemonstrationwilltaketime.Market share: It isanticipatedthat this innovationwillbe implementedon10%ofplants in2025,asitsusewillprimarilybefocusedon(theverylimitednumbersof)newplants,andnewer,existing plants which are operating at high capacity.

Introduction of waste heat recovery

Practice today: Waste heat recovery is generally not incorporated in plant units as small as 225MWtoday.Innovation: Theinnovationcoverstherecoveryofsensibleandlatentheat(heatofcondensationof steam in flue gas) which replaces the use of bleed steam for feed-water preheating. Bydirecting bleed steam to the condenser, more power can be produced from the same amount offuelduetoa1.5%increaseofpowerplantefficiency.Commercial readiness: 80% of the benefit of these innovations is realisable in 2016, with100%realisableby2020,asthetechnologiesexist,butexperienceofintegrationisashort-termobstacle for a small number of power plants.Market share: Itisanticipatedthatthisinnovationwillbeimplementedononly30%ofplantin2025,duetotherelativelyhighcostcomparedtothebenefits.

Improvements in steam flow in turbines

Practice today: Steam flow in the turbine is continuously improving. The latest power plants use new blade designs, new seals, valves, and new low-pressure outlet and condenser designs.Innovation: This innovation covers the continued development in all these areas, focusing on increasedefficiencyandreducedOPEX.Commercial readiness: 50%ofthebenefitoftheseinnovationsisrealisablein2016,with80%realisableby2020and100%by2025.Muchofthetechnologyalreadyexistsforretrofittingandnew technology will be developed as new plants are delivered.Market share: Itisanticipatedthatthisinnovationwillbeimplementedon30%ofplantsin 2025. It is unlikely tobehigherbecauseof the relativelyhigh cost compared to thebenefits.

Introduction of high temperature superconducting (HTS) technology in powertransformers and cables

Practice today: Power transformers and cables mainly use copper as the conductor. Thermal management,electricalinsulationandconductionmaterialssignificantlyaffectservicelifetimeandreliability.Transformerefficiencycanbeashighas99%.Innovation: Theinnovationcoversuseofmaterialswithlowerlosses,specificallyHTStechnologyin transformer windings, transmission cables and fault current limiters. As well as reducing losses,HTStechnologiescouldreducefailuresandmaintenancecostsinthesesystems,butalsointroduce potential extra complexity.Commercial readiness: 10% of the benefit of these innovations is realisable in 2016, with50% realisableby2020and100%realisable from2025,as the technologiesexist,but requiredevelopment and commercialisation during this period.Market share:Itisanticipatedthatthisinnovationwillbeimplementedon30%ofplantin2025.Implementation is limited due to the relatively high cost compared to the benefits achievable over the remaining life.

5.e.2. InnovationsInnovations in the emissions treatment system span a range of technologies from pollutant control, through carbon dioxide capture and waste ash treatment. A subset of the more important of these has been modelled here.

In addition, an innovation in abatement methods for carbon dioxide was considered. This would increasetheLCOEfromthebaselinesysteminthetimeframeupto2025,andsoisnotincludedin the overall analysis. Increases in the costs for emitting carbon dioxide, and significant reductions inthecostofthetechnologycould,however,reducetheLCOEinapplicationsinthelongerterm.

Introduction of simultaneous pollutant control methods

Practice today: Current pollution control happens in series. First, oxides of nitrogen are managed through combustion control, followed by selective catalytic or non-catalytic reduction in the exhaust stream. Then sulphur oxides are removed in a wet or dry process using calcium-based sorbents. Finally, dust is removed using cyclones and electrostatic filters.Innovation: This innovation covers simultaneous reduction of all pollutants in the exhaust, using hybrid methods, sorbents and oxidisers in wet scrubbers. Commercial readiness:60%ofthebenefitoftheseinnovationsisrealisablein2016,with80%realisableby2020and100%by2025,theonlybarrierbeingthedriverofemissionslegislationtodeliver the final developments required.Market share: Itisanticipatedthatthisinnovationwillbeimplementedon40%ofplantsin2025,assumingallplantsusingcoalonly(ratherthanacoal-biofuelmix)willneedthistechnologytomeet emissions regulations by then.

Table5.6andFigure5.8 showthat the innovationwith the largestanticipated impact inFID2025isimprovementsinpreventativemaintenance,whichreducesunexpectedfailureandlostgenerationtimeaswellasreducingOPEX.

5.f.2. InnovationsInnovations in the operations and maintenance of plants cover a range of technologies from control and sensor systems and algorithms to maintenance processes. A subset of the more important of these has been modelled here.

Improvements in control systems

Practice today: Mostofthedistributedcontrolsystems(DCS)installedonolderpowerplantsuse conventional control algorithms, implemented when the boiler was originally commissioned. During the life of the plant, control hardware and user interfaces have generally been upgraded, but control algorithms have not usually changed.Innovation:Thisinnovationcoversadvancedprocesscontrolmethodsincludingneuralnetwork,fuzzy logic, computational models and other advanced, multidimensional algorithms. These control innovations may target any part of the power generation process; however the main focusisthecombustionstage,whereimprovedcontrolwillimproveefficiencyandreduceOPEX.Commercial readiness: 80% of the benefit of these innovations is realisable in 2016, with100% realisable by 2020, because new control ideas and innovations can be implementedindependently of the original manufacturer of control system without significant cost.Market share:Itisanticipatedthatthisinnovationwillbeimplementedon40%ofplantsin2025.

The application of this solution is limited by factors including the age of the distributed control system, the condition of instrumentation and control equipment and the condition of boiler as well as the strategy of the plant operator.

Improvements in diagnostics and measuring systems

Practice today: Coal plants use extensive sensors, measurements systems and diagnostic tools to support monitoring and control of the power generation process.Innovation: This innovation covers the development of advanced sensors and diagnostic systems to improve and extend the inputs to the control system. Innovations include:•Thermal stress monitoring systems, which provide detailed information about dangerous

stress in critical components and enable prediction of the remaining life of components, and•Advanced sensors to measure qualitative process parameters such as flame quality, combustion processes,emissionssystemsefficiencyandbyproductquality.

Commercial readiness:80%ofthebenefitoftheseinnovationsisrealisablein2016,with100%realisableby2020,becausenewsensorsandmeasurementanddiagnosticsystemsarealreadyin use in other industries, and others are currently in the later stages of development. Market share: It isanticipatedthatthis innovationwillbe implementedon40%ofplants in2025,becausetheadditionalbenefitsareeasiest toachieve inconjunctionwiththoseplantsundertakingimprovementsinthecontrolsystem.

Improvements in preventative maintenance

Practice today: 70% of coal plants have been in operation for 20 years ormore, and theiraverage life is 45 years. Their integrated maintenance strategy combines regular planned overhauls with emergency action if equipment fails between overhauls. Basic IT systems and remote monitoring systems inform asset management. Innovation: This innovation covers preventative maintenance algorithms, which provide information about failure in advance, and new maintenance strategies based on operational conditions, device conditions and their remaining estimated life.Commercial readiness: 60%ofthebenefitoftheseinnovationsisrealisablein2016,with90%realisableby2020and100%by2025,asthedevelopmentofmodelsofsystemconditionandremaining life needs until the end of the period.Market share: It isanticipatedthat this innovationwillbe implementedon40%ofplants in2025,becausenewworkingpracticeswillbelimitedbystrongdependenceonlocalconditionsand the operator of the plant.

6.ConclusionsInboththegasCHPandcoalSectionsofthisreport,weconsideredalargenumberofinnovationswith thepotential to reduce LCOEby FID 2025. The commonmajor theme inboth cases isreducingthepartofOPEXrelatingtothecostofthefuelusedperMWhofelectricityproduced,thoughthisisachievedthroughdifferentmethods.

In the case of the gas CHP plant, reduced fuel OPEX is achieved through innovations thatimprove the electrical output achieved per unit of fuel consumed. The four major innovations here are in engine mechanical design and in boosting systems, which both help increase power density,inleancombustion,whichhelpsincreasethermalefficiencyandintheuseofalternativegaseousfuels,whichreducesOPEX.

In the caseof the clean coalplant, reduced fuelOPEX is achieved through innovations thatenable the use of lower cost fuel and waste products. The three major innovations here are thermal pre-treatment of biomass and waste-based fuels, hybrid fuel combustion, and fuel modification(withadditivesandhigherproportionsofwaste-derivedfuel).

Improvements in operations also deliver significant savings, and include innovations in preventative maintenance, start-up and operational flexibility, and in treatment and disposal of the byproducts of solid-fuel combustion.

In total, forbothTechnologyTypes,nearly40different innovationswere identifiedand theirpotentialtoimpactLCOEintheconditionsmodelledwasevaluated.Ofthese,28innovationsmadeapositivecontributiontoreducingLCOEandhavebeenpresentedhereindetail.Someof the other innovations could have a small impact in the timescales of this study, but have significantpotentialtoimpactLCOEoverlongertimescalesordifferentconditions(forexamplewhereemissioncostsaremuchhigher).
