Slide title Technical requirements & Results
• 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
•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

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
Slide title
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
Slide title
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, …
