Outline
• Biofuels in Europe now and in the future• Effect of biofuel blending on air quality• Measurements and evaluation conducted by LAT
on SVO and biodiesel blends• Conclusions • Future activity

Biofuels in Europe, 2006
Ethanol Ethanol 16.3%16.3%
Others Others 12.1%12.1%
Biodiesel Biodiesel 71.6%71.6%

• Increasing use of biofuels under EU policy framework
• Important share of “other” biofuels (mainly SVO)

Future trends
Source: European Biofuels Technology Platform 2008
• 35Mtoe biofuels required in 2020 from which 75% diesel substitutes and 25% gasoline
• Where these fuels will come from? The current skepticism appears justified.
• Limited resources, best available practices for the transition period from first to second generation technologies

Impact of biofuels on emissions and air quality
Source: US EPA
Is this a realistic picture of what should be expected in Europe in the near
future?
• Studies indicate positive results on exhaust emissions from biodiesel introduction except on NOx
• Most studies based on older engines, or different quality diesel
• Few data regarding real world operation
• What about non regulated pollutants?
6
LAT experimental activities
• Evaluation of biofuels on exhaust emissions, regulated and non regulated
• Application of B10 EN14214 blends from various raw materials on a Euro 3 Common rail passenger car for 17000km
• Application of unesterified cottonseed oil on the same vehicle for 11000km
• a raw material of great importance for Greece which is not preferred by biodiesel factories
• derived from specialized refining and treatment process
• Utilization of legislated and real world simulation (Artemis) driving cycles
