Slide title

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, …
