  1. WEBINAR Cities’ experience with biofuels 14/01/2013 14.00-15.30 Gerhard Ablasser, City of Graz

  2. Background & Objectives • City of Graz – fact • 265.000 inhabitants • 121.000 employees • 70.000 daily commuters • 4 universities with 50.000 students • area of 127 km² • UNESCO World Heritage since 1999 • Cultural Capital City of Europe in 2003 • OSMOSE Award 2006 • CIVITAS City of the year 2008 CIVITAS Webinar 00/00/2013

  3. „From the frying-pan into the tank“

  4. Ökodrive-Ecodrive - the project 1990Start collection of used cooking oil from private households 1994 Starting of pilot project - Research work on Biodiesel from used cooking oil • operation of 2 buses of the public transport service (GVB) 1999Start collection of used cooking oil from restaurants 2003 EU Project CIVITAS/ trendsetter operation of additional 54 buses with biodiesel 2005100 % biodiesel public transport fleet (135 buses) 2005EU Project KAPA / GS equipment with particle catalytic converters

  5. Collection of used cooking oil private households more than 250 restaurants, hotels, snackbars... Öko-Service / Eco-Service

  6. Good partnership:Company SEEG-company converting used cooking oil to biodiesel

  7. Company BDI / with Technical University / Chemical Institute / Transport Company (GVB)

  8. Good partnership:Graz Karl Franzens University Institute for Organic Chemistry Technical University Graz: Institute for Internal Combustion Engines and Thermodynamics

  9. Good partnership:PublicTransport Company Graz (GVB)

  10. Technical requirements & Results • check of all assemblies supplied with biodiesel (heaters) • exchange of fuel hoses • certification from the engine manufacturer • consent from the supplier of the injection pump • motor oil change every 30.000 km, but no special oil was needed • no greater wear of the engine • 5 – 8 % higher consumption • combination with fossil diesel in winter • biodiesel is cheaper ( depents on tax regulations ) • scientific examination

  11. Motives for GVB - public transport operator • price of biodiesel fuel is lower - no mineral tax • but: 5 - 8% higher consumption of biodiesel • pioneer for environment protection • ecological aspect • interest in technical progress for better air quality • image improvement of Public Transport

  12. Lessons learned I • you need a very motivated team in all sectors of the partnership that is responsible for the running fleet • high international interest about the experience of Graz but less followers in Austria • using Biodiesel as a fuel made from waste material was the right step but only a step in the right direction • The experience of Graz opened the way for blending biodiesel in a large scale

  13. Lessons learned II • no future for 100% biodiesel with new generations of engines, EURO VI but a way to do something positive with all older buses immediately • problems with particulate catalytic converters; livetime of 2 – 3 years is not acceptable • Problems with heating system can be solved with a dual tank system • to not discuss – you must start to do it

  14. The future in Graz • Pilot with 4 CNG Mercedes since March 09 • Hybrid bus test since spring 09 • Electric bus test since February 2013 • preparation of the future way – at the moment it seams to be CNG with a high focus on local produced biogas • Using the experience of European projects and learning from European partners to find the right solution • focus on other private and public fleets like taxies, public services, …
