8 The Chinese transport sector adapts slowly to Europe and North America Context – Transport Sector OverviewThe Chinese transport sector adapts slowly to Europe and North AmericaNorth AmericaPassenger transport relies mainly on passenger vehicles30% of final energy consumption20% of GHG- EmissionsEurope30% of final energy consumption20% of GHG-EmissionsChinaPassenger transport relies on passenger vehicles and public transportPassenger vehicles become an increasingly important mode of transport8% of final energy consumption9% of GHG-EmissionsOne aspect of the framework for Co-Evolution in which the three regions differ is the economic importance of the transport sector and the importance of passenger vehicles for personal transport. While Europe and North America (both regions basically make up the developed world) show similar characteristics for this aspect, the situation in China is very different. In China, personal transportation is a market that has immensely grown during the last few years.Transport sector has fastest growing energy use and strongest reliance on fossil fuels of all economic sectors worldwide.
9 Context –Economic Situation Diverse Economic and Population Background - North America and Europe are comparableGDP per capita (PPP)North America and Europe have a GDP of 4 and 3 times the world average, respectivelyChina has a much lower GDP per capita (0,7 times the world average)Population342 million – North America500 million – Europe (EU27)Low population density in Nordic Countries1.3 billion – ChinaHigh density only in southern and eastern ChinaUrbanizationHigh rates in North America (80%) and Europe (72%) & Northern Europe (79%)Much lower urbanization (47%) in China Urban Chinese population surpasses both North America’s and Europe’s totalWorld AverageSource: IfHT, values from World Monetary Fund1 billionSource: IfHT, values from CIA & EurostatGDP = Gross Domestic Product; PPP = Purchase Power ParityThe Gross Domestic Product expressed per capita in Purchase Power Parity values takes price differences between different countries into account. Thus, these values are better comparable than pure GDP values.The Urbanization rates of Europe and North America, again, are close. 75% of European population (77% (N) – 92% (IS) of Nordic) live in cities while 80% do so in North America (more in Canada than in US). Thus, especially Nordic Europe and North America are similar regarding their population levels.Sources:International Monetary Fund (for GDP per capita (ppp))Eurostat, Statistics Canada, US Census Bureau, CIA – The World FactbookUnited Nations, Department of Economic and Social Affairs, Population Division: World Urbanization Prospects, The 2009 revision.Nordregio 2010100%Source: IfHT, values from UN
10 Differences in Vehicle ownership and Market development Context – Vehicles MarketDifferences in Vehicle ownership and Market developmentNorth AmericaEuropeChinaVehicles on Road277 million210 million~55 millionPassenger Vehicle Sales12 million (2009)16 million (2009)10,3 million (2009) 13,7 million (2010)Vehicles per 1000 people830473Nordic: 500Eastern: 38054 Beijing: 228Overall Market situation todayStagnating, expected to increase as of 2012StagnatingStrongly growing (doubling of sales within 3 years)The road infrastructure differs between the three regions. Refer to Annex A13 for details.Vehicle ownership and market development for passenger vehicles again are similar for North America and Europe. However, North American vehicle ownership per person is unequalled by any other region. China‘s situation is especially interesting regarding the potential for Electric Vehicles and Co-Evolution. Low vehicle ownership and strong growth of vehicle sales may facilitate the market entrance of electric vehicles.Sources:US Census Bureau, State Motor Vehicle Registrations.Statistics Canada, Motor vehicle registrations.Eurostat
11 Context – Chinese Vehicles Market Chinese market will be catching up on Western levels – further extreme growth expectedHighest global sales of passenger vehicles as of 2009Sales more than doubled within 3 years~ 13.7 million new passenger vehicles in 2010Further growth expected, especially for lower-margin subcompact and compact cars2010Vehicle Sales (Total/ Passenger Vehicles Commercial Vehicles)The booming market for passenger vehicles and the further expected growth especially for subcompact and compact cars opens opportunities for electric vehicles. At the right price electric vehicles could be preferred over conventional cars.

12 Context – Passenger traffic Cars are most important for passenger traffic and will most likely stay soEurope and North America rely mainly on private cars for passenger transportImportance of vehicles is mirrored in available infrastructure (Annex A13)Further increase in traffic expected for the European UnionPassenger traffic activity + 51%, 2005 – 2050Reasons:ImmigrationExpansion of the Union (increase in labor mobility)Economic growthIncrease in labor mobilityNorth AmericaEuropeShare of passenger-km in private cars93%83%Travelled km per person and year15,000 – 20,000ca. 10,000Nordic: 14,000 – 20,000Especially in North America and Europe, cars are most important for personal transport needs. While public transport networks in China and Europe take up most or some of the passenger-kilometers, in North America public transport is almost exclusively used in cities.

Quantification of healthy life years lost in Europe”- report which gives an estimate of 1 million disability adjusted life-years (sum of the potential years of life lost due to premature death and the equivalent years of “healthy” life lost by virtue of being in states of poor health or disability) that are due to environmental noise. A huge proportion of environmental noise is traffic-related, in cities especially to vehicle traffic.It is estimated that EVs production capacity (per model and year) will be needed for economies of scale.An estimate of the present value of investments required for developing the electric road transport infrastructure in the EU amounts to € billion.
15 EVs are a niche market Context – Transport Sector – Electric Vehicles EVs are close to the marketThis will change with increased adoption and information to the general public.North AmericaEuropeChinaEV sales (2009)1.1% of passenger vehiclesJDPower: 2,8% sales1% of passenger vehicles0,4% of vehicles(distribution below)Only HEVs,BEVs sales negligibleE-Bikes and E-Scooters includedLess than 0,01% of vehicles on road are EVs2020 Outlook3-10% of passenger vehicles on the road ( )5% TargetMarket share of 3-10% = 0,45-1,5 million EVs in Europe in 2025, seen as “realistic”As of end of 2010 there have been 7466 EVs (BEV, PHEV, HEV, FCEV) delivered in China.

16 Context –Electric Vehicles & GHG Mitigation Benefits regarding GHG emissions strongly depend on the regional electricity mixEVs considered as low- or no-emission-vehiclesTechnically this depends on the electricity mixEVs powered by coal-fired power plants emit >800gCO2/ kmNighttime charging can result in both increasing the share of RES-E and in increasing the share of fossil base-load electricity and thus in higher emissionsEmissions of EVs are 50% of ICEVs’ with current European electricity mixEmissions of EVs are 89-74% of ICEVs’ with current USA electricity mixGHG emissions lower in Canada (2006 data) because of higher proportion of RES-E (depending on province)Using RES-E, GHG emissions could be reduced to 75%-38% of ICEVs’ to which the new CAFE standards of 35.5 mpg by 2016 apply.ICE BC AB SK MB ON QC NB NS PEI NL200100Electricity mixes for the three world regions can be found on slide 41.Sources:European Parliament, 2010: Challenges for a European market for Electric VehiclesEuropean Environment Agency (2009): Towards a resource-efficient transport system.CANMET Energy, Electric Vehicle Technology Roadmap for Canada, 2009.GHG = Greenhouse gas – EV = Electric vehicleICEV = Internal combustion engine vehicle RES-E = Electricity from Renewable SourcesCAFE standards = US fuel efficiency standards
17 Context – Transport Sector – Emissions of EVs GHG emissions from electric vehicles are beneficial only in some Chinese regionsIn China the high share of coal-based electricity in the grid increases EVs’ emissions above those from conventional ICEVs (2010 data)The electricity mix in the more densely populated southern and eastern China decreases EVs’ emissions below conventional valuesThe northern regions that today have the highest emission values have large unconnected wind resourcesN NE E C NW S Hai Av ICEElectricity mixes for the three world regions can be found on slide 41.Sources:Earley et al, 2011: Electric Vehicles in the Context of Sustainable Development in ChinaGHG = Greenhouse gas – EV = Electric vehicleICEV = Internal combustion engine vehicle RES-E = Electricity from Renewable Sources
18 Context – Electric Vehicles – Economic Influence Low gas prices in North America and China reduce interest in EV’s cost-benefitsGas prices and gas tax are low in China, Canada and the USA relative to EuropeGas prices around the world (US $ per gallon, 2011)Source:Since many potential electric vehicle users shrink back at the price, the total costs of ownership are the most important financial argument for electric vehicles. However, these costs can only compete with those from conventional vehicles if the price difference of the fuel types is high enough. Thus, low gas prices reduce the margin in which electric vehicles are cheaper than conventional ones (cumulated over the entire lifetime).
19 Context – Electric Vehicles – Economic Influence General transport sector emissions policies influence also the deployment of electric vehiclesGHG emissions are taken into account through taxation in many European countries (map) (Dark Blue: more than one taxation scheme, Light Blue: one kind of CO2-tax) and in ChinaTax benefits from this taxation reduce impact of cost-difference compared with conventional carsNo taxation of GHG emissions of passenger vehicles in North AmericaElevated electricity costs in Nordic countriesInfluence the economical viability of EVsVariety of policies regarding future of transportShift of commodities to rail and inland navigationIncrease of public transportHolistic approach provides less secure framework for investmentsAn overview of policies that concern the deployment of electric vehicles can be found in Annex A5.Another aspect that influences the total costs of ownership of electric vehicles is the taxation these vehicles are subject to. This aspect can be varied according to governmental targets and is therefore an interesting policy instrument.In Europe, vehicle taxation is more and more based on GHG emissions. The map shows the distribution of GHG emissions-based taxes in Europe. Dark couloured countries have implemented more than one taxation scheme that takes CO2-emissions into account. Light couloured countries have implemented only one form of incentive. The measures include: registration tax, annual circulation tax, company car tax, deduction of vehicle use, incentives for purchase of an environmentally friendly car (sometimes bound to scrapping an old car first)Vehicle taxation in China is based on displacement and fuel consumption (proportional to CO2-Emissions) of the vehicleSources:ACEAFinish Energy Industry ,2011: Energy taxation in Europe, Japan and the United StatesEuropean Parliament, 2010: Challenges for a European market for Electric VehiclesEuropean Commission, 2011: White Paper.

20 Societal change drives the deployment of electric vehicles Context – Electric Vehicles - DriversSocietal change drives the deployment of electric vehiclesUrbanizationUrban areas experience most traffic problemsHigh population density in urban areas warrants investments in infrastructureUrban population tends to early adoption of new technologiesSo far the number of EVs (per head) is biggest in citiesBut:Charging infrastructure faces competition for spaceImmigration and labor mobilityIncrease mobility needsCustomer acceptance of new mobility patterns, of the look, space and performance of EVsThe main driver for the deployment of electric vehicles in cities is the increasing number of people living there. This increases traffic problems and local emissions and calls for new mobility solutions. Immigration – thus, an increase in population – and increasing labor mobility also increases traffic volumes. However, even the biggest need for alternative transport solutions will not lead to an increased deployment of electric vehicles unless the potential customers accept the look, space and performance of these new vehicles and are also willing to accept changes in their personal mobility patterns. Successful car-sharing and bike-rental projects show that people are accepting new mobility solutions.Sources:EurostatEuropean Parliament, 2010: Challenges for a European market for Electric VehiclesSessa & Enei, 2009: EU transport demand: Trends and drivers
21 Context – Electric Vehicles – Drivers Technical and political development will have strongest influence on EV deploymentPolitical and regulatory supportSubsidiesInfrastructure developmentPilot projectsRecommendations from funding organizations207 models recommended for subsidies in China only these models are eligibleSome European countries publish catalogues of vehicles that are entitled to benefitsStandardizationSecure framework for investments from stakeholdersDevelopment of vehicle energy storage systemsLonger driving rangeLower battery costsA list of support policies for electric vehicles can be found in Annex A3. Framework policies that concern the deployment of electric vehicles can be found in Annex A5.Some drivers for the deployment of electric vehicles are universally the same. The importance of political and regulatory support, early standardization and advances in the development of vehicle energy storage systems are needed for opening markets for electric vehicles, for providing security for manufacturers and comfortable usage for customers.The sustainability of the deployment of electric vehicles has to be taken into account for devising support policies!
22 Context – Electric Vehicles – Drivers The availability of charging infrastructure is a basic requirement for electric vehicle deploymentSecurity aspect for usersNecessary for widespread EV usageQuick-charging is now being implemented in the Nordic European countriesApril 12, 2011 Denmark's first quick charge station opened (max. 20 minutes for 80 % SOC)2 stations have been build in the Oslo area in NorwayBattery swapping stations will be built in Denmark (Figure: Projection for 2012)In China all three charging technologies are/ will be testedSome pilot cities have already published standardsSlow charging and battery swapping are preferred by grid companiesNo governmental preferences yetFirst trials have shown that EV users prefer to charge their vehicle at home. However, widespread charging infrastructure is needed for giving users the security that they can charge their vehicle whenever they need. While everyday use is within the range of an electric vehicle, on-road charging will be needed for exceptional trips. The extend to which vehicles will be sufficiently standardized for enabling battery swapping remains unclear.
23 Electric vehicles do not meet with favorable conditions everywhere Context – Challenges for EVsElectric vehicles do not meet with favorable conditions everywhereDiverse climate conditionsAll three regions encompass various climate zones with cold winters in the north and humid and hot summers in the southThese climatic differences will lead to different battery lifetime and vehicle availabilityLandscape and road conditions varyAreas with low population density increase infrastructural costs for widespread deploymentMidwestern America, western and northern China, northern EuropeFor first usage in cities population density is not an issueAgeing population in North America and EuropeAgeing people remain increasingly mobile and thus cause more trafficAn increasing share of governmental funds has to be dedicated to careFunding for new technologies becomes more difficultSources:European Parliament (2010): Challenges for a European market for electric vehicles
24 Complementary use rather than replacing conventional vehicles Context – Electric Vehicles – MarketsComplementary use rather than replacing conventional vehiclesElectric vehicles are typically second carsCommutingGermany: most commuting distances are 80 km or underThis is absolutely within EVs rangeInner-City-TrafficReduction of local emissionsNoiseGreen House Gases and ParticlesShort distances, stop and goIntegration into Car-Sharing programsNo individual perception of purchase costsPublic electric vehicles in ChinaBuses & Taxis – uniform fleets allow economies of scale and battery swappingSanitation vehicles, postal cars, other public services’ vehiclesA list of EV models that are available in the three regions is listed in Annex A6.Electric vehicles are and will be deployed first as second vehicles that are used mainly for commuting and inner-city traffic. These usage patterns are within the range electric vehicles can drive and their users keep their first cars for any other trips. The integration of electric vehicles into car-sharing programs is possible, too.In China the first deployment today is mostly made up of public vehicles – especially buses and taxis. The pilot cities thus can buy large numbers of identical vehicles which all have the same requirements on charging infrastructure and result in economies of scale for vehicle manufacturers. Private electric vehicles are only subsidized in five cities (see slide 29).In Montreal, car-sharing program Communauto will be adding 50 Nissan LEAF EVs to its fleet of 1000 vehicles by the end of The charging infrastructure will be provided by Hydro Quebec, the principal electrical utility.Sources:European Parliament, 2010: Challenges for a European market for Electric Vehicles
25 Usage models have different requirements on EVs and infrastructure Context – Electric Vehicles – MarketsUsage models have different requirements on EVs and infrastructureInner-City trafficShort distances, low requirements for speedSlow charging, mostly at homeCommutingMedium requirements for distances and speedSlow charging, at home and at workCar sharingShort and medium distances, low and medium speedSlow charging at stations, maybe battery swappingInter-City-TrafficLong distances, high requirements for speedFast charging and battery swapping on roadThe requirements on electric vehicles from different usage patterns show why first deployments in cities are so attractive. Distances travelled while commuting or in inner-city-traffic are within the range of electric vehicles. Additionally, the requirements for speed are medium hight. Vehicles in car-sharing fleets have approximately the same requirements. Thus, slow charging “at home” (= at sharing station) and at work combined with the possibility to fast charge on the road will suffice. Only long distance traffic e.g. between cities that also requires high speed will need fast charging and/ or battery swapping possibilities “on the road”.
26 Context – Electric Vehicles – Business Models EVs should be offered in a package including additional transport and other servicesPublic transport ticket(s)Rental car serviceCombination with car-sharing programs?Installation of home charging pointAccess to charging stations/ reserved parking spotsFree charging on public charging stationsFlat rate for charging current from RES-EPay-per-mile battery leasing offersMaintenance servicesGuarantee on battery and vehicle partsInsuranceElectric vehicles are part of a transition in the transport sector. As such their deployment should be complemented by offering mobility solutions for the needs that are not easily fulfilled through electric vehicles (long-distance travel).The public acceptance of electric vehicles can be increased by offering services packages that include charging points and convenient accounting solutions.

34 Safety standards are especially important Context – Electric Vehicles – StandardizationSafety standards are especially importantDiffering vehicle standards between the USA and Canada (involving bumpers, seat belts, side door strength, metric indicators, etc.).To be harmonized by 2012There is a need for nation-wide harmonized standards for after-market ICE vehicle conversion.Safety of plugs and the charging process is a concern besides design, number of phases & voltage level for chargingPure electric vehicles from independent manufacturers may not be as equipped for safety as modern cars are (airbag, anti-lock brakes, electronic stability control etc.)
35 Targets for Electric Vehicles on the road Context – Electric Vehicles – ObjectivesTargets for Electric Vehicles on the roadNorth AmericaUSA: 1 million electric vehicles on the road by 2015The EV project which encom-passes 18 urban areas in six states will install 14,000 chargers (residential and public)Canada: 0.5 million electric vehicles on the road by 2018EuropeSum of national targets: 5 million electric vehicles on the road until 2020Needed growth rates for these targets range from 20,000 – 250,000 EVs per year over a 2 – 20 year periodDifferent pilot projects have targets for charging stationsChina0.5 million electric vehicles on the road by 20155 million electric vehicles (5%) on the road by 2020Most ambitious national target worldwideEach pilot city has targets for charging stationsNational targets for infrastructure:- Portugal: 1300 slow charging stations and 50 fast until end of 2011 in Portugal.The European accumulated national targets amount to 5 million electric vehicles. This means a market share of 30% assuming that the overall number of vehicles remains constant. Thus, the European targets are most ambitious which is mirrored in the growth rates of 20,000 – 250,000 new electric vehicles per year. Whether these values will be achieved is highly uncertain.

37 Context – Electric Vehicles – Regulatory Barriers The lack of standards makes long-term planning difficult for vehicle and infrastructure manufacturersNo coordinated effort between car-making markets in terms of regulation (regarding emissions standards which were agreed on in Europe & China or the type of technologies to support) yet.Makes planning effectively for the long term difficult for auto-makersCan be somewhat mitigated by technology-sharing agreements between companiesHinders large-scale deployment (i.e. Chevrolet intends to produce only 10,000 units of the Volt in its first year of production in the United States).No political will to implement high fuel taxes to stimulate the greatest advances in vehicle efficiency and alternative vehiclesIncreasingly strict fuel efficiency standards are a good first stepAn overview of EV related standards can be found in Annex A7.

Vehicle to grid services are taken into account only in two North American pilot projects. However, vehicles taking up and feeding back renewable energy from and into the distribution grid might steady the feed-in from renewable sources and provide reserve power to the grid which could earn revenue for the owner. For offering significant amounts of reserve energy, vehicles should be aggregated into groups.Sources:"Kortlægning af strategier for lavenergibyggeri i EU Lande", COWI 2011, Report for the Danish Government.

46 Electricity grids are very different in the three regions Context – GridsElectricity grids are very different in the three regionsNorth AmericaOld and not always reliableInvestments decreased over last yearsGrid structure is radial, meshed in regions with high population densityLow overall population density makes expansion costlyIntegration of EVs possible in some regionsEuropeStable and modernGrid structure:Transmission: meshedDistribution: meshed, loop or rayIntegration of EVs possible for up to 40% penetration in most gridsChinaStrong expansion of the transmission grid is going onDistribution grids are not always fit for integrating either RES-E or EVsThe North American grid has grown from regional grids. Investments during the last decade were low because the grid capacity sufficed. Today, investments have to increase to assure supply security. Since especially densely populated regions are likely to experience failures, a modernization of the grid is urgently needed. In China, the grid is straining to keep up with the increasing demand due to the economic growth. Here, both transmission and distribution grids have to be expanded for enabling an increased share of RES-E and EVs and still assuring supply security.European grids generally are in a good shape. They can take up a high share of electric vehicles. However, locally an increase in both distributed production and electric vehicles may result in overloads.Source:Jenny Gold (2009): A Modern Electric Grid: The New Highway System?

57 Cooperation between stakeholders needed for Co-Evolution Co-Evolution – General RequirementsCooperation between stakeholders needed for Co-EvolutionCo-Evolution only possible if both EV deployment and RES-E production are encouragedRES-E production needs to increase for Co-EvolutionTariffs for charging with RES-E need to be developedCooperation between stakeholdersVehicle and infrastructure standardsFacilitating RES-E integrationProvide possibilities for RES-E chargingGlobally coordinated development of standardsSynergies can only emerge if technological development does not take different directionsInternational cooperation between stakeholders of the Co-Evolution of electric vehicles and renewable electricity is crucial for this Co-Evolution. Especially the development of vehicle and infrastructure standards is needed for international compatibility issues and economies of scale. The range of standards that is needed also encompasses tariff structures for RES-E charging.
58 Both RES-E production and EV deployment rely on electricity grids Co-Evolution – System RequirementsBoth RES-E production and EV deployment rely on electricity gridsGrids need to be sufficiently stable and/ or expanded for accommodatingNew centralized (off-shore/ on-shore wind) and distributed (solar PV, micro-wind, etc.) productionPreference for centralized RES-E production means more attention on transmission grids. Security of supply is seen as more important than increasing the share of RES-E.Additional distributed loadBattery swapping stations could stabilize and centralize demandA preference for home charging means increased (distributed) household-loadOpportunities for high penetration of EVsRegulated chargingFor better capacity utilizationFor taking stress off the distribution grid (assets)Storage of RES-EIncrease share of RES-EProvide reserve power for gridStabilize feed-in from volatile sourcesFor a Co-Evolution of renewable electricity and electric vehicles the stability of the electricity network has to be guaranteed at all times. Both the integration of new production and new loads can increase the stress on the grid’s assets. Battery swapping stations and centralized RES-E production in big plants can simplify the management of load and production. Battery swapping stations can answer to demand side management with more capacity than single EVs (and vehicles do not have to be aggregated for offering a similar capacity).Today’s hope that a high penetration of electric vehicles will lead to an increased share of stable, “produced-on-demand” renewable electricity fed into the grid after having been stored in electric vehicles’ batteries will only be possible with a sophisticated communication infrastructure that links RES-E production and electric vehicles.PV = PhotovoltaicsRES-E = Electricity from Renewable Sources

78 Co-Evolution – Feasibility of policy options Two-phase long-term policy approach needed for large scale Co-Evolution of EVs and RES-EPrepare for EV’sInfrastructure and standardizationPilot fleets in niche markets for learning effects and cost reductionsProvide long term perspective to industryIncrease RES-E productionPriority access for renewablesFeed-in tariffs or premiumsRPS or obligationsCap and tradeGrid stabilityEnsure balanced grid developmentCoordinate technical and institutional effortsSmart grids and active load management/ regulated chargingLong distance transmissionPhase 1MarketPreparationDetails on two-phase roadmaps for the three regions can be found in Annex A12. In the following different policy options are presented with their strengths and weaknesses.Phase 1 should be aimed at gaining experience. Learning effects which are mainly influenced by accumulated production numbers enable vehicle OEM’s to produce vehicles at lower costs. Also in phase 1, the different needed standards should be defined AND IMPLEMENTED. The shape of the plugs used for charging EV’s for instance as well as the voltage level / frequency should be defined. Also, the standard to which the “smart grid” should comply, as well as appliances (chargers) that are attached to this smart grid. Since in phase 1 (roughly between now and 2015) EV’s will not be on the road in significant numbers, the advanced V2G (vehicle to grid) services mentioned earlier are not needed yet.3rd column: Priority access to prevent night charging of EV with coal-based baseload powerPhase 2 is aimed at using the increased number of EV’s to achieve not only co-evolution / co-existence, but also additional benefit. For this, the advanced V2G services should be in place. This is what “ increase system integration” means in this context.[Martine: suggest to change latter sentence to: with active load management (Phase IV in Ch 4 of report, several benefits can already be gained without V2G]Optional information:An interesting parallel might be to briefly mention the abundance of adapters needed to fuel LPG powered vehicles in Europe. This has come about since different countries started using different gas connections without first defining a standard connection. The end result is that LPG cars from the Netherlands are incompatible with the filling nozzles in Belgium for instance. And since all the necessary investments have already been made, nobody (car drivers, OEM’s and fuel station operators) is willing to change anything about this.Increase deployment of EV to reach mass marketsIncrease system integration to enable higher use of EV and RES-EPhase 2Deployment78
79 Regulatory framework Phase 1 Co-Evolution – Feasibility of policy optionsRegulatory frameworkPhase 1Emission targets for electricity production and vehicle fleets warrant other support policiesTargets for the deployment of electric vehicles are an incentive for first deploymentsStandards for vehicles and infrastructure provide security for manufacturersConsequenceLegitimate base for further policiesOpposition from the people (North America)FeasibilityFeasible in all regionsEmission targets are more easily implemented for electricity than for existing vehicle fleetsStandards have to be based on technological consideration and have to be implemented quicklyDetails on two-phase roadmaps for the three regions can be found in Annex A12.

81 Coupling Renewable Energy and Electric Vehicles Co-Evolution – Feasibility of policy optionsCoupling Renewable Energy and Electric VehiclesHard CouplingElectricity for charging electric vehicles is coupled to the absolute additional RES-E share in the electricity mixCap and TradeElectricity production or the deployment of vehicles have to fulfill emission targets (cap)Any additional demand for electricity or additional deployment of vehicles has to be provided from carbon-neutral sources or has to be compensated by GHG emissions reduction measures applied to other emitters that are part of the system (trade)Manufacturers’ investments in RES-EVehicle manufacturers can count their electric vehicles as zero-emission vehicles if they finance new RES-E productionGrid Stabilization BonusSystem Operators pay this bonus for plugged-in electric vehicles that can either provide demand side management or ancillary servicesTax Exemptions for Charging RES-EElectric vehicles are only eligible for tax exemptions if they charge RES-ERe-Investing electricity tax from charging currentDetails on two-phase roadmaps for the three regions can be found in Annex A12.Six policy options for promoting the Co-Evolution of electric vehicles and electricity from renewable sources were suggested in the RETRANS project.
82 Tax Exemptions for Charging RES-E Co-Evolution – Feasibility of policy optionsTax Exemptions for Charging RES-EPhase 1Vehicles are eligible for tax exemptions if they charge RES-EExemptions from annual vehicle/ motor/ circulation taxesConsequenceAdditional RES-ECost benefits for EV owners as an incentiveIncreased willingness to plug in?CostsAdvanced billing system and separate metering neededFeasibilityFeasible for low penetrations of EVs.Phase-out for higher penetrationsEV owners have to be able to exclusively charge RES-EFeasible in all regionsTax Exemptions for Charging Electricity from Renewable Energy Sources are granted only for those vehicles which are indeed powered by renewable electricity. This condition can be added to the sets of criteria that are in place for choosing those vehicles that are eligible for benefits today. Tax Exemptions are a policy option that is feasible in all three regions. However, this option needs a special RES-E charging tariff for identifying the amounts charged. Especially in North America, such indirect fiscal incentives are likely to be publicly accepted.
83 Re-Investing Electricity Tax Co-Evolution – Feasibility of policy optionsRe-Investing Electricity TaxPhase 1The electricity tax from the traction current is invested in additional RES-EConsequenceAdditional RES-ESpecial electricity tariff/ separate metering for EVs neededMarket distortion in deregulated marketsFeasibilityFeasible in all regionsIn North America this option might be possible only within one interconnection-areaRe-Investing the Electricity Tax from the Charging Current into new renewable electricity production plants is only feasible if electricity taxes exist and amount to a significant contribution for new renewable electricity. As with tax exemptions for charging renewable electricity, this option requires a special charging tariff for electric vehicles. It is feasible in all three regions. Deregulated electricity markets in North America and Europe may be distorted. In North America this option may first be restricted to single interconnection areas.
84 Hard Coupling Phase 1 Co-Evolution – Feasibility of policy options Coupling electricity for EVs and absolute RES-E TargetsAdditional EVs have to be met with additional RES-E capacityConsequenceEVs powered by pure additional RES-ECosts (user & society)FeasibilityUnlikely for North America, because profitability is key for public acceptance of both EVs and RES-EFeasible for Europe but concerns exist that this option may slow down EV or RES-E deploymentIn China – based on policies until today – this option is unlikely. However, if RES-E production is increased significantly and charging business models are set up, Hard Coupling may become feasibleHard Coupling means that the electricity which is needed for charging new electric vehicles has to be generated from new renewable energy sources. Thus, the amount of electricity that is produced from these sources increases according to the increase in electric vehicle deployment. In Europe this measure is feasible but raises concerns that the development of renewable electricity or electric vehicles may be slowed down. Increased costs for the society are expected. In North America and China this option is unlikely because both regions have not even implemented Renewable electricity targets. In North America profitability is key for public acceptance of EVs and RES-E which also is a barrier for this option. The regulated Chinese electricity market would facilitate the implementation of this option.
85 Manufacturers‘ investments in RES-E Co-Evolution – Feasibility of policy optionsManufacturers‘ investments in RES-EPhase 1EVs are considered Zero Emission Vehicles (ZEV) in return for investments in renewable electricityOEMs invest in additional renewable electricity production (depending on MJ/km per sold EV)DSOs invest energy tax for traction current in additional RES-EConsequenceAdditional RES-ECan lead to more emissions from ICEVs – Coupling to fleet emission standards!Conflicts of interests possibleFeasibilityFeasible in Europe, has to be introduced for all countriesThe vertically integrated electricity markets in China and North America may impede implementation (if OEMs are new players in the market)For more information see Annex slides section A14.Vehicle manufacturers invest in new renewable electricity (equalling the amount their EVs are going to use) and can then consider their electric vehicles as zero-emission vehicles. However, emission targets for manufacturers’ fleets have to be in force first. Else, this option might result in higher emissions from remaining conventional vehicles. This option might be feasible in all regions. The vertically integrated electricity sectors in China and North America impede the market entry for OEMs as RES-E producers. Cooperation with the grid companies may be possible. In China, private investments in RES-E are not encouraged. A political change would be needed. Since the electricity mix in China depends on governmental decisions, it has to be ensured that the new renewable capacity is used. In Europe, this option is feasible but has to be implemented on the European level.
86 Cap and Trade Phase 2 Co-Evolution – Feasibility of policy options A Cap and Trade system for fleet emissions per vehicle manufacturerComparable to the ETS and other C&T systems, emission targets will be adjusted over timeEarnings from the emission certificates trading can be invested into new RES-EConsequenceAdditional RES-E / CCSNeeds strong regulatory frameworkTakes effect only on new vehiclesFeasibilityFeasible in all countriesLess likely in North America and China because national Cap and Trade systems for GHG emissions do not exist yet.A Cap and Trade system that couples electric vehicles and electricity from renewable sources sets emission targets for the electricity sector (as in the European Trading Scheme) and the transport sector. As this emission target becomes stricter, the rights to emit have to be traded between the stakeholders. This option may be feasible as a Phase 2 policy option. National or international emission mitigation targets are a premise for Cap and Trade systems. If these are introduced in Phase 1, Cap and Trade schemes that encompass the electricity and the transportation sector are feasible in all regions. In North America emission mitigation targets have to be enforced. In Europe, emissions from electricity production are already included in a Cap and Trade scheme. The integration of the transport sector into that scheme may be possible, the details of the implementation remain unclear. In China this option is feasible, it is feared that such a scheme may slow down the economic development of vehicle manufacturers.
87 Grid Stabilization Bonus Co-Evolution – Feasibility of policy optionsGrid Stabilization BonusPhase 2EVs receive a bonus payment for plugging in and thus being available for storage and feed-in of volatile RES-EConsequenceBetter RES-E utilizationStable gridsAdvanced metering and implementation (billing!) neededFeasibilityThis option is only feasible, if advanced metering (bidirectional!) is already installed on a large scaleProfitability is key for successful implementationFirst Countries: Italy, Sweden, Norway ?The Grid Stabilization Bonus is paid for by DSOs who reward owners of electric vehicles for plugging-in and making their vehicles available for ancillary services. This option is only feasible if smart grid and bidirectional charging technology is available. Depending on the regional development, this option may become feasible in Phase 2 in all regions. This option is a good incentive for encouraging EV owners to plug-in.

Thus, a market driven development for an increase in EV deployment is most likely.Both electric vehicles and renewable electricity will be first implemented regionally. Thus, renewable sources will not necessarily be available for local EVs but have to fuel EVs that are deployed elsewhere. However, the local implementations will drive grid reinforcements there. Public information campaigns can help changing opinions about renewable electricity and electric vehicles.In Phase 2 market entry for new renewable electricity producers may become easier. Consumer demand for Vehicle to Grid services and Feed-In Tariffs may lead to new legislation.

The electricity sector has to quickly catch up on RES-E production and ist transmission.In Phase 2 bidirectional charging infrastructure for vehicles-to-grid services becomes increasingly important for managing both increasing production and increasing demand.

101 North America & Europe Conclusions Cities and urban areas will be breeding grounds for EV deployment and charging infrastructureEV expansion to rural areas is highly unlikely in the medium term due to infrastructure and social acceptance issuesIn Phase 1 EVs will not feed back power to the grid outside of pilot projectsNo problems arise in European grids for the projected low shares of EVsMeasures for increased deployment:Support policies (subsidies, tax benefits and other support policies)Battery cost reduction / improved performancePublic information campaignsMeasures for system integrationGet ISO’s involved in pilot projects or local development projectsGrid upgrades and smart grid development to allow for bi-directionality and regulationRegulate grid expansion as a part of a feed-in tariff program (eg. suggested for Province of Ontario)Support policies for electric vehicles include: subsidies for acquisition (might be combined with scrappage incentives), tax benefits (on registration fee or annual taxes), traffic privileges, insurance benefits, access to transport services.Support policies for renewable electricity might continue or be expanded. However, if technologies reach market parity, support policies might only take effect on their interaction with electric vehicles (e.g. benefits for participating in smart grids).
102 ConclusionsChina – Co-Evolution requires changes in renewable electricity and electric vehicles deploymentBoth grid and battery technology require technological innovation in China in order to support the integration of EV and RECharging models must be matched with RE grid interaction models in order to take advantage of clean energy in EVs, and suitable business models need to be developedEmphasis should be on increasing overall RE on the gridAt this time, China is focusing on large-scale RE including wind and solar projects, with little attention paid to distributed RE generation.Private power plants are not approved in China at this time. All power must enter the grid and be downloaded from the grid.There should also be an emphasis on increasing population of EVs – to the scale of millions of vehicles.It is unlikely that smart grid will be economically viable or technologically useful without such large numbers.Incentives are needed for both vehicles and grid companies in order to attain a critical mass of vehicles and smart grid participants.

105 Comparison of regions Lessons learned so far ConclusionsComparison of regions Lessons learned so farOutcome of pilot projects:EVs alone cannot solve traffic problems – an integrated approach and a new concept of transport are necessaryUser acceptance:EVs for a set purpose are well acceptedBusiness cases:Car-sharing/ Mobility Partnerships for commutingUsage patterns:Local solutions for traffic problems and personal mobilityInfluence of RES-E deployment and potentialPotential for RES-E not fully exhausted yetSustainability of RES-E for EVs absolutely vital for ecological benefitsElectricity tariffs that guarantee RES-E for charging EVs are neededMore information about pilot projects in the three regions can be found in Annex A4.Mobility Partnerships are Packages where the acquisition or leasing of an electric vehicle makes the owner eligible for reduced fares on public transport, rental cars, parking spaces and other – locally defined – benefits. Plug-and-Ride offers from railway companies for electric vehicles are one example of a Mobility Partnership with two stakeholders.Finding local solutions for traffic problems and personal mobility goes hand in hand with the mentioned mobility partnerships. Depending on local circumstances (urban/rural, size of the city, availability of public transportation ...) usage patterns (distances, usage frequency etc.) differ and different bundles will be needed. Depending on the usage patterns different EV models may be necessary.
106 Comparison of regions Lessons learned so far ConclusionsComparison of regions Lessons learned so farPolicy options & public acceptanceAn uninformed public does not accept EV promotion “from above”Information campaigns on the benefits of EVs neededIncluding financial, fiscal and non-monetary benefits for usersPolicies furthering EVs and RES-E have to be adapted to regional characteristicsImportant regional differences between policies in Phase 1Possible synergies between regions in Phase 2Skepticism regarding Co-EvolutionLow RES-E shares reduce benefitsTechnological and regulatory hindrances in foreground
107 Follow-up work Conclusions Analysis of the outcome of the different pilot projectsWhich co-operations were fruitful and whyWhat makes EVs successfulExperience with Co-EvolutionAppraisal of technical / grid-related boundaries and barriers to Co-EvolutionImpact Assessment of policy optionsAs more and more pilot projects worldwide advance an analysis of the success factors of electric vehicles will be necessary. Why were EVs accepted and used? Were the users satisfied? Which companies and organizations worked together and what were the success factors in this cooperation? What business models and tariff structures were introduced? Which experiences were made regarding the Co-Evolution with renewable electricity? In what scales were smart grids or V2G involved?From this analysis best practices can be derived which again can help promoting EVs, RES-E and their Co-Evolution.Technical and grid- or system-related boundaries and barriers for Co-Evolution have to be appraised per region or even on smaller scales. This appraisal is needed for developing feed-in and charging strategies that help stabilizing the grid.An impact assessment of the suggested policy options is needed for giving policy makers a help for prioritizing these options.
