Biogasmax is a FP6 project of the EC
The two major objectives of the project are:
• Demonstration of large scale digestion and biogasupgrading units with waste material available in urban and close by rural areas
• Demonstrate and expand biogas fleets in publictransport
3
Biogasmax includes 28partners and 6 demonstrationsites:
• Lille (FR), Coordinator
• Region of Göteborg (Swe)
• Stockholm (Swe), incl. Västeras
• Berne (Swi)
• Rome (IT)
• Zielona Gora and Torun (Poland)

How does the Berne consortium work together?
15 year contract between BERNMOBIL and Energie Wasser BernBERNMOBIL agrees to exchange 70 diesel buses with gas bussesewb supplies filling station and delivers fuel (biomethane and natural
gas)ewb pays for the additional investment cost of busses out of its eco-
fund
Long-term contract between Ara Region Bern AG and ewbarabern upgrades enough gas for the operation of at least 30 gas
busses (1,3 GWh p.a.)ewb pre-finances the upgrading plantewb pays a lower price for 13 M Nm3 biomethane to pay the
investments back
The goal is that by 2011 all 70 buses are operated on biomethane

A label as highest standard of biomethane

LCA

The top label: naturemade
• Together with ok power the strongest label for green electricity
• it is supported by environmental and consumer groups
• it is highly accepted in the population and in industry
• it uses scientifically based evaluation methods
It was evident to use the label also for biomethane
On February 23, 2009 arabern was certified!

Comparison Euro5 Diesel – Gas bussesCNG Diesel Remarks
NOx Elimination> 40 t p.a.
Elimination > 30 t p.a. 75 t p.a. without filter (INFRAS)
CO2 eq. Reduced by2000 t CO2 p.a. Same as today 1 m kg biogas (approx. 30 busses)
CO2-neutral, Biogas from WWTP
Noise approx. 63 dB approx. 66 dB
Ammonia (Urea) NoneWith low exhaust temperature existing
NOx BERNMOBILshare Reduced to 9% Reduced to 12%
BERNMOBIL’s share on traffic emissions in Bern before biogas busses was 15%
Particle mass PM10 irrelevant irrelevant Before gas, 1.07 t p.a. were emitted

Experience with gas bussesDuring 15 months the bus operation of 45 buses were carefullymonitored:
• In total, 26 different recurring problems were encountered.The sevenmost often occuring problems had nothing to do with gas
• In total, only 15% of the problems were due to gas as fuel (one per 2300km)
• Only one major problem was connected with gas: All cylinder heads had to be changed
In conclusion: The next 30 buses will not be ordered from Volvo for 2 reasons:
• There were (too) many little problems disturbing operation
• Volvo could not deliver Euro 5 buses in timeThe new buses will be delivered by Mercedes
