Abstract [en]

Electric vehicles seem to offer a great potential for sustainable transport development. The Swedish pioneer project GreenCharge Southeast is designed as a cooperative action research approach that aims to explore a roadmap for a fossil-free transport system by 2030 with a focus on electric vehicles. In the first paper of this tandem publication, the authors propose a new generic process model embedding the Framework of Strategic Sustainable Development. The purpose of applying it in an action-research mode as described in this paper was twofold: (i) to develop a vision for sustainable regional transport and a coarse roadmap towards that vision, and, while doing so, (ii) get additional empirical experiences to inform the development of the new generic process model. Experts from many sectors and organizations involved in the GreenCharge project provided vital information and reviewed all planning perspectives presented in Paper 1 in two sequential multi-stakeholder seminars. The results include a sustainable vision for electric vehicle systems in southeast Sweden within a sustainable regional transport system within a sustainable global society, as well as an initial development plan towards such a vision for the transport sector. The vision is framed by the universal sustainability principles, and the development plan is informed by the strategic guidelines, of the above-mentioned framework. Among other things, the vision and plan imply a shift to renewable energy and a more optimized use of areas and thus a new type of spatial planning. For example, the vision and plan implies a lower built-in demand for transport, more integrated traffic modes, and more multi-functional use of areas for energy and transport infrastructures, for example. Some inherent benefits of electric vehicles are highlighted in the vision and plan, including near-zero local emissions and flexibility as regards primary energy sources. The vision and plan also imply improved governance for more effective cross-sector collaboration to ensure coor- dinated development within the transport sector and between the transportation sector and other relevant sectors. Meanwhile, the new generic process model was refined and is ready to be applied and further tested in the GreenCharge project and in other projects within the transport sector as well as other sectors. The study confirmed that the new generic process model suggested in support of sus- tainable transport system and community development is helpful for giving diverse stakeholders, with various specialties and perspectives, a way of working that is goal-oriented and builds on effective, iterative learning loops and co-creation.

Abstract [en]

This article aims to develop and test a new approach for comparing sustainability effects (mainly approximated through CO2 emissions) and the total cost of ownership of various business models (Regular Purchasing, Car Pooling, Car Leasing, and Taxiing) applied to private cars with different energy carriers (Biogas, Ethanol, Gasoline, Plug-in Hybrid, and Electric). The results indicate that, out of all of the vehicles, electric vehicles are the most competitive—from both an ecological and economic perspective. Moreover, of all of the business models, Car Pooling is the most competitive when driving short to medium distances, reducing CO2 emissions by 20-40% compared with Regular Purchasing. Meanwhile, Car Leasing emits the same amount of CO2 emissions as Regular Purchasing if both are driven the same number of kilometers per year. The results also indicate that, from a cost effectiveness perspective, people who travel less than 2000 km per year should primarily consider using Taxis or similar services, while Car Pooling is most cost effective for those who travel from 2000 to 8500 km. For those who travel between 8500 and 13500 km per year, Car Leasing is the most cost effective, and Regular Purchasing is the best option above 13500 km per year. If most car owners were to accept and adapt to this identified need for a market move towards Car Pooling with Electric Vehicles, necessary transportation could be ensured while significantly reducing the number of cars on the road, whether from Regular Purchasing or Car Leasing, as well as those that run on fossil fuel. This, in turn, would result in less fossil fuel use, fewer emissions, and decreased negative effects on human health.

Abstract [en]

Between 1950 and 2013 the total amount of Swedish travelling has increased from about 20 billion to about 140 billion passenger kilometers. This included an increase in travelling with private cars from about 3 billion to about 105 billion passenger kilometers, and in bus travelling from about 2.5 billion to about 5 billion passenger kilometers. The European commission has indicated that public transportation (if powered by clean fuels) is a suitable way to reduce environmental and health problems.

 

This thesis focuses on sustainable personal road transport, and aims to develop and test a new approach to examining the economic and socio-ecological sustainability effects of various road vehicles for private travelling and related business models. A special focus is set on comparing various bus systems for public transport and ways (business models) for private people to access cars. The main comparison parameters are the total cost of ownership and carbon dioxide emissions of different energy carriers for buses and cars. The Design Research Methodology is used to guide the research approach. The approach also builds on the Framework for Strategic Sustainable Development, which includes, for example, principles that define any sustainable future and a strategic planning process. The approach first employs Strategic Life Cycle Assessment to give a quick overview of sustainability challenges in each bus life cycle stage from raw materials to end of life. Several analysis tools such as Life Cycle Costing, Life Cycle Analysis, Product Service System, and Business Model Canvas mapping are then iteratively used to ”dig deeper” into identified prioritized challenges. Literature reviews, interviews, and simulations are used as supporting methods.

 

The results from a first theoretical test of the new approach suggest that a shift from diesel buses to electric buses (powered by renewable energy) could significantly lower carbon dioxide emissions, while also significantly lowering the total cost of ownership. The theoretical calculations were followed up by testing of electric buses in real operation in eight Swedish municipalities. The tests verified the theoretical results, and showed that electric buses are better than diesel buses both from a sustainability point of view and a cost point of view, and also that electric bus operation is a practically viable alternative for public transport. The new approach was tested also by comparing a variety of business models for private car travelling. The results indicate, among other things, that only people who travel more than 13.500 kilometers per year would benefit from owning a car.

 

In all, the thesis suggests a simultaneous shift from diesel buses to electric buses in public transport and, for the majority of the car drivers that drive less than 13.500 kilometers per year, switching from car ownership to car use services would be favourable for an affordable transition of the transport sector towards sustainability.

Abstract [en]

From a theoretical perspective, Electric buses can be more sustainable and can be cheaper than fossil fuelled buses in city traffic. The authors have not found other studies based on actual urban public transport in Swedish winter climate. Further on, noise measurements from buses for the European market where found old. The aims of this follow-up study was therefore to test and possibly verify in a real-life environment how energy efficient and silent electric buses are, and then conclude on if electric buses are preferable to use in public transport. The Ebusco 2.0 electric bus, fitted with a 311 kWh battery pack, was used and the tests carried out during November 2014 to April 2015 in eight municipalities in the south of Sweden. Six tests took place in urban traffic and two took place in more of a rural traffic setting. The energy use for propulsion was measured via logging of the internal system in the bus and via an external charging meter. The average energy use turned out to be 8 % less (0,96 kWh/km) than assumed in the earlier theoretical study. This rate allows for a 320 km range in public urban traffic. The interior of the bus was kept warm by a diesel heater (biodiesel will probably be used in a future operational traffic situation), which used 0,67 kWh/km in January. This verified that electric buses can be up to 25% cheaper when used in public transport in cities for about eight years. The noise was found to be lower, primarily during acceleration, than for buses with combustion engines in urban bus traffic. According to our surveys, most passengers and drivers appreciated the silent and comfortable ride and preferred electric buses rather than combustion engine buses. Bus operators and passenger transport executives were also positive to start using electric buses for public transport. The operators did however point out that procurement processes need to account for eventual risks regarding this new technology, along with personnel education. The study revealed that it is possible to establish a charging infrastructure for almost all studied bus lines. However, design of a charging infrastructure for each municipality requires further investigations, including electric grid capacity analysis, smart location of charging points, and tailored schedules to allow fast charging. In conclusion, electric buses proved to be a preferable alternative for all stakeholders involved in public bus transport in the studied municipalities. However, in order to electric buses to be a prominent support for sustainable development, they need to be charged either by stand-alone units or via an expansion of the electric grid, and the electricity should be made from new renewable sources.

Abstract [sv]

GreenCharge Sydost är en sammanslutning av regionförbund, kommuner, landsting och företag medett övergripande syfte att främja införandet av elfordon i främst sydöstra Sverige. Blekinge TekniskaHögskola är huvudman för projektet med ansvar för att driva forskningen, och Miljöfordon Syd attdriva den operativa projektledningen avseende demonstrationer och samverkan med intressenter.Under 2013 gjorde forskningen inom GreenCharge en beräkningsstudie som påvisade att elbussar urett livscykelperspektiv har mycket mindre utsläpp än dagens dieselbussar och totalkostnaden skullekunna bli 25 % lägre över en 8-års period i Karlskrona på linje 1 och 7, 21 % i Jönköping på linje 1och 3, samt 17 % i Sundsvall på linje 2 och 4. Detta gäller under antagande att bussen drivs med nygrön el, att realränteökningen blir 1 % per år samt att energi-pristrender sedan 10 år tillbaka fortsättergälla framöver.. Beräkningsstudien antog också efter simuleringar utifrån befintliga linjer och aktuellavärden från busstillverkare en energianvändning på 1,04 kWh/km för eldrift.

Abstract [en]

To reach Swedish national climate change reduction targets, organizations collaborate for a sustainable development to improve energy efficiency, reducing pollution and noise in public bus transport. This follow-up study continues to strengthen the previous study by deepen the economic comparisons of two electric buses with different driving range and different type of chargers. The study aims to emphasize on sensitivity analysis for the total cost of ownership (TCO) to reduce uncertainty by identifying which factors of interest that most likely cause the estimated cost values for the electric bus. The result shows that the percentage change of line distance (km/year), operational years, and investment cost would be the most influential and significant factors on TCO.

Abstract [en]

European national, regional, and local authorities have started to take action to make public bus transport services more effective and less polluting. Some see the possibility to move beyond a narrow focus on efficiency or carbon dioxide reductions towards an integrated sustainability perspective. This paper uses this perspective to build and test a new assessment approach that should enhance decisions on bus transport powertrains and energy carriers for Swedish medium-sized cities. The study suggests that a superiority of electric powertrains is revealed if a traditional economic analysis is integrated with a strategic sustainability perspective.

Abstract [en]

Vehicles, infrastructure, fuel systems and other energy-driven systems that serve public transport are complex with many resource inputs and outputs, and involve many processes. Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) helps analyzing those by quantifying environmental and economic effects, but will not in themselves provide a full systems perspective. Swedish authorities have set ambitious national goals, and many regions targets a 100% increase in public transport by 2020. The medium sized city of Karlskrona (36,000 inhabitants), that is included in this study together with Sundsvall and Jönköping, embraces those goals too. This study analyzes relevant differences between bus solutions, to investigate a change to more sustainable bus propulsion systems. The study zooms down to compare energy carriers (diesel, biodiesel, biogas, and electricity) in different powertrain combinations (combustion engines, electric hybrids, and pure electric). The Framework for Strategic Sustainable Development (FSSD) where principles are defining a sustainable future is used to broaden from a cost and environmentally shortsighted perspective to a long-term sustainability perspective with systems thinking. The Strategic Life Cycle Assessment (SLCA) is first used to give a quick full scope of sustainability challenges in each bus life cycle stage from extraction to end of life. Then LCA and LCC approaches are used to” dig deeper” into prioritized identified challenges. Initial study results suggest that electric drivetrains would be preferable in city buses within the coming decade - both from an economic and a sustainability perspective. It not only lowers emissions and energy usage, but also provides a platform for future promising energy carriers.

Abstract [sv]

Dagens vägtransporter hjälper människor att berika sina liv genom möjlighet till snabba, flexibla och bekväma resor, samt förbättrad tillgång till varor och tjänster. Dock bidrar dagens vägtransporter till hållbarhets- problem och andra problem såsom klimatpåverkan, buller, barriärer i landskapet och olyckor med dödlig utgång. Det svenska samhället har under de senaste decennierna börjat uppmärksamma de stora hållbarhets- utmaningarna världen står inför. Regeringen har satt mål för växthusgasneutralitet år 2050 och en fossil- oberoende fordonsflotta 2030, samt andra mer närtida miljömål. Tyvärr pekar bl.a. indikatorer i miljömåls- portalen på att de flesta av dessa mål inte kommer att uppfyllas. Samtidigt kommer bebyggda områden att förtätas och vägtransporter förväntas öka. Vägtrafikens negativa påverkan på människors hälsa kommer därför att öka om ingen förändring görs, framförallt i stads- miljö. För att bidra till hållbar utveckling behöver utsläpp från lastbilar, bussar och personbilar minska. Regionala och kommunala organisationer kan bidra till omställningen till hållbarhet bl.a. genom ökade krav på lokaltrafikens fordon så att de blir mer energieffektiva, samt avger mindre luftföroreningar och buller. Bussar med elektrifierad drivlina, som laddas med förnyelsebar ny el, är i dagsläget ett lovande alternativ för en sådan förändring. Ett högt inköpspris för eldrivna fordon är i dagsläget ett hinder i upphandling för kollektivtrafik, men det kan komma att sjunka med ökade försäljnings- volymer och teknisk utveckling, framförallt beträffande batterier. Tidigare studier visar på fördelar för eldrift av bussar i storstadsmiljöer (Stockholm, Göteborg och Malmö). Denna studie syftar till att utreda hållbarhets- implikationer och lönsamheten i att använda bussar med någon form av eldrift i kollektivtrafiken i mellan- stora städer jämfört med dagens bussar som drivs med förbränningsmotorer. Med hjälp av Blekingetrafiken, Jönköpings Länstrafik, Västernorrlands kollektivtrafik- myndighet och Volvo Technology Corporation har författarna gjort fallstudier på utvalda stadsbusslinjer i Karlskrona, Jönköping och Sundsvall. Studien tillämpar metodik för strategisk hållbar utveckling som utvecklas i en internationell vetenskaplig samverkansprocess med Blekinge Tekniska Högskola som koordinerande nod. För att bl.a. undvika suboptimeringar ur ett helhets- perspektiv (förbättringar i en fas som kan ge fler och större problem i andra faser, samt hindra global hållbar utveckling) används strategisk livscykelanalys (SLCA) för att identifiera särskilda analysområden, livscykel- analys (LCA) för kvantifiering av emissioner, och livs- cykelkostnadsanalys (LCC) för beräkning av lönsamhet och konkurrenskraft. Beräkningar baseras på tidigare studier och dessa kom- pletteras och verifieras genom simulering av energi- användning för respektive linje. Författarna har valt att studera energibärare då dessa utgör största skillnaden mellan traditionella fossildrivna bussar och de som drivs med el i någon form. Studien utgår från diesel med 5 % FAME/RME och lokalt producerad förnybar ny el från källor som per år ger mer till nätet än vad som tas ut, exempelvis genom s.k. vindkraftsandelar. Eldrift förekommer i tre varianter varav två är hybrider. Primär drivkälla för elhybrid är förbränningsmotorn, vilket förväntas spara i snitt 33 % energi gentemot en dieseldriven buss. Laddhybrid drivs primärt av elmotor med batterier (laddas internt och externt) samt i andra hand av förbränningsmotor, men kan styras till att bli 100 % eldriven. För att utreda lämpligt biobränsle för dessa studeras lokalt framställd biogas ur hushållsavfall och biodiesel (RME) från lokalt odlad raps. Det senare har ur tillgänglighetssynpunkt valts som bränsle till elhybrid och laddhybrid i denna studie. Slutsatserna från studien är att bussar för stadstrafik i medelstora städer som primärt drivs av el (från lokala vindkraftsandelar) jämfört med dieseldrift är... ... tydligt bättre i alla livscykelfaser beträffande energi- effektivisering och emissioner bidragande till växt- huseffekt, försurning, övergödning, skapande av marknära ozon, och partiklar. Detta trots nyttjande av knappa material som Litium i batterier. Det finns också potential till radikal minskning av ljudnivån på bullriga platser. En elhybrid- eller laddhybrid- buss bör ur miljösynpunkt drivas med biogas. ... enligt ekonomisk nuvärdeskalkyl ekonomiskt kon- kurrenskraftiga när anskaffning av laddinfrastruktur (en extra snabbladdare), fordon, samt underhålls- kostnader (med 1 batteribyte), energianvändning (årlig prisökning med 6 %) inkluderas. Elhybrid är 7 %, laddhybrid 18 % och helt eldriven buss 24 % billigare än dieseldrift i Karlskrona (linje 1/7). Lokalt producerad förnybar ny el ger dessutom nya lokala och regionala arbetstillfällen, vilket kan värderas mer än det gjorts i denna studie. ... om något år ekonomiskt lönsamma för linjer vars sträckning kräver mer än 5 snabbladdningsstationer. Resultaten visar på vissa skillnader mellan de studerade städerna, som till största del beror på utnyttjandegraden av bussar, linjernas karaktär, samt stadens storlek och ventilationsfaktorn. Förbättringar ur miljösynpunkt jämfört med dieseldrift är ganska lika i de studerade städerna, men besparingspotentialen (i kronor) för elhybrid-, laddhybrid och el-drift är störst i Karlskrona.
