5 Stadtbusse in der Beschaffung/ Procuring Clean Buses 11. Dezember Bremen 5 Calculations: McKinsey for BMU, 2010 Remark: -50% is lower Safety line for 2 degrees target All sectors with reductions except transport sector, e. g. Germany reduction of all sectors by 30 % between 1990 and 2010; transport: reduction only 9,8 %. Reductions for 2°C-target needs in- sector achievements, i. e. no shift of obligations between sectors Targets for Transport Sector in Germany: Reduction Final Energy Consumption by 10 % (2020) and 40 % (2050); discussion about national sectoral targets Transport EU: Reduction of CO 2 - emissions by 60 % compared to 1990 until 2050 (Concept Text Transport) Energy EU: Minimum share of 10 % renewable Energy in the Transport Sector until 2020 EU-wide emissions sectors in CO2e, index. (1990=100), Eurostat Global challenge for transport

Dezember Bremen 7 total emissions transport demand [passenger km] energy intensity [joule per pkm] CO 2 - intensity [CO 2e per joule] = xx approaches Avoid traffic e.g. reduce needs for mobility and distances by means of integrated planning Shift traffic and push efficiency e.g. reduce fuel consumption of vehicles and shift traffic to towards more efficient modes Switch fuel e.g. use low carbon fuels such as sustainable biofuels or renewable electricity Source: Composition of total emissions in passenger transport, simplified display after Creutzig/Edenhofer in IVW Hybrid busesElectric buses How to reduce emissions in passenger transport?

8 Stadtbusse in der Beschaffung/ Procuring Clean Buses 11. Dezember Bremen Stand: Dezember 2007 Instruments of sustainable mobility Emission standards - Land transport EURO-standards - Environmental zones Reduction of transport noise - Innovation programmes for rail vehicles - EU-standards for tyres - International Noise standards for airplanes - Requirements of BImSchG (e. g. noise action plans) Taxes as environmental steering instrument - Reduction of fuel taxation for public transport - Benefits for refit with particulate filter - Tax exemptions for fuels with significat reductions of CO 2 emissions Support/ funding of environmental beneficial vehicles - New version of national transport plan (in preparation) - Environmental standards for public procurement in public transport - National cycling plan

9 Stadtbusse in der Beschaffung/ Procuring Clean Buses 11. Dezember Bremen 9 Key reasons for funding better buses Main goals Reduction of CO 2 -emission, pollutants and noise within the sector of public transport Support of Market penetration with existing, highly efficient transport technologies Establishing new technology with lower emissions as permanent element in the fleet of transport companies Stimulation of economy for bus industry and related suppliers Increase attractiveness of Public Transport Noise measurement (source: BMU)

10 Stadtbusse in der Beschaffung/ Procuring Clean Buses 11. Dezember Bremen 10 What are better buses? Main elements – different stages Reduction of air pollutants, mainly NOx and PM: today SCR, particulate filter Gas buses?:1. CNG: no real CO 2 -benefit 2. lower NOx/ PM emission 3. Biogas: CO 2 -benefit dependent on well-to-wheel balance, waste problem, competition with food 4. Noise problems remain Hybrid buses: efficiency technology, introduces electric mobility to public transport Electric buses: various technologies available, test phase, main challenges: battery and charging

11 Stadtbusse in der Beschaffung/ Procuring Clean Buses 11. Dezember Bremen BMU project 2010/ companies: –Stadtverkehr Lübeck GmbH –Üstra Hannoversche Verkehrsbetriebe AG –10 transport companies in Saxony Introduction of 50 hybrid buses in scheduled service 65 – 85 % of extra costs for hybrid elements and support 11

12 Stadtbusse in der Beschaffung/ Procuring Clean Buses 11. Dezember Bremen Environmental criteria BMU project Definition of ambitious environmental criteria in order to promote market entry and to save environmental standards: –Reduction of CO 2 -Emissionen by 20 % compared to equivalent dieselbus –NO X - and PM-emissions at EEV level –Exhaust aftertreatment with closed particulate filter –Underscore EU-noise level 12 Control of criteria with extensive research program: noise measurements on testing area, control of emissions on roller test bench, extensive additional analyses on practicability, technical problems, cost- benefit, acceptance

13 Stadtbusse in der Beschaffung/ Procuring Clean Buses 11. Dezember Bremen Continuation of support of hybrid buses As of 2012 new project with financial support of the BMU-National Climate initiative (NKI) Huge political support for promotion of new climate friendly technologies 13 Environmental requirements (like 2010) - 20 % improvement compared to conv. veh. - EEV plus closed particulate filter, EuroVI underscore noise standards Key issue: cost effectiveness/ profitability Main goal: closure of gap between costs and return Result: - despite reduced funding rate about 60 buses in the programme as of today, e. g. in Hamburg, Wolfsburg, Ingolstadt

14 Stadtbusse in der Beschaffung/ Procuring Clean Buses 11. Dezember Bremen E-buses – a new perspective with potential New trend - No local LAQ emissions - good climate balance, but only with renewables - reduction of noise emissions Energy storage –Regular service of urban buses of 300 km and more with corresponding energy consumption of about 500 kWh –Recharging in most cases necessary Fast charging: –Due to limited stopping time high charging power necessary (200 kW or more) –Further work required on infrastructure Auxiliary technology (heating, climatisation, …) –Extra energy source or significant increase in electric energy consumption Further evolution - main challenges battery and recharging/ time for recharging - economic consideration - environmental performance towards climate 14 * Quelle: Fraunhofer

21 Stadtbusse in der Beschaffung/ Procuring Clean Buses 11. Dezember Bremen Fuel consumption: first results Comparison with comparable conventional diesel vehicles (Euro V/EEV) BMU-Projekt - 12 projects with fuel savings of up to 19% (average > 10 %) - dependency on route characteristics, technology, energy storage, manufacturer (some at the beginning with extra fuel consumption) - variations over the year: better results over summer WG buses (only few months, statistical uncertainties) - 12 m: up to 34 %, 18 m: up to 21 % (some below 10 %) - average between 10 and 20 % currently - parallel hybrids significantly better, robust results over 20 % - first companies expect break-even during lifetime (!) - complete restart of cost-benefit analysis -> FURTHER DETAILED ANALYSIS NECESSARY

22 Stadtbusse in der Beschaffung/ Procuring Clean Buses 11. Dezember Bremen Test bench measurements/ noise All buses within BMU project achieved requirements for NOx/ PM (PM below detection limit) Exhaust temperature higher than concv. Engines (SCR) CO 2 reductions between 20 and 30 % 22 Gelenkbus auf dem Rollenprüfstand (Diesel- Referenz), (Quelle: TÜV NORD) Geräuschmessung auf der ISO-Messstrecke in Papenburg (Quelle: TÜV NORD) Significant reductions of noise in particular in front part of the bus Perception of passengers and among pedestrians: much lower noise, very important element of acceptability

23 Stadtbusse in der Beschaffung/ Procuring Clean Buses 11. Dezember Bremen Some conclusions Significant GHG reductions in transport sector required to achieve 2°-target Other important requirements: air quality and noise reduction Public transport one important element but further improvement of technology necessary Technological evolution started and is accelerating: more electricity (with all suboptions) and less conventional fuel. Hybrid buses as new element in German and European fleets introduced Various projects on different paths: hybrid buses, plug-in hybrid buses and electric buses E-buses as new element with main challenges battery, charging and costs High acceptance of new technologies among passengers and pedestrians, but also drivers New bus trends lead to more sustainability: less emissions, less noise Economic questions/ cost effectiveness will remain as one key issue 23
