Experience In Berne Switzerland Arthur Wellinger

  1. 1. Experience in Berne, Switzerland UK National Biomethane Conference Arthur Wellinger Site Leader Berne Nova Energie GmbH arthur.wellinger@novaenergie.ch 1
  2. 2. Biogasmax is a FP6 project of the EC The two major objectives of the project are: • Demonstration of large scale digestion and biogas upgrading units with waste material available in urban and close by rural areas • Demonstrate and expand biogas fleets in public transport 2
  3. 3. Biogasmax includes 28partners and 6 demonstration sites: • Lille (FR), Coordinator • Region of Göteborg (Swe) • Stockholm (Swe), incl. Västeras • Berne (Swi) • Rome (IT) • Zielona Gora and Torun (Poland) 3
  4. 4. The Partners BERNMOBIL Energie Wasser Bern ARA Region Bern (ARB) 4
  5. 5. How does the Berne consortium work together? 15 year contract between BERNMOBIL and Energie Wasser Bern BERNMOBIL agrees to exchange 70 diesel buses with gas busses ewb 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 ewb arabern upgrades enough gas for the operation of at least 30 gas busses (1,3 GWh p.a.) ewb pre-finances the upgrading plant ewb 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 5
  6. 6. Arabern: the production site 6
  7. 7. Production targets Goal: 2.6 Mio Nm3 Biomethane by 2011 Trend: Biogas Increase Biomethane Mio Nm3/a since 2006 Mio Nm3/a [%] 2006 4'702’728 2007 5'239’398 11.4 2008 5'700’510 21.2 ca. 1.8 7
  8. 8. Co-Substrates 8
  9. 9. Upgrading with PSA 9
  10. 10. Gas upgrading 10
  11. 11. A label as highest standard of biomethane LCA Data bank 11
  12. 12. 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! 12
  13. 13. The New BERNMOBIL CNG-Busses 13
  14. 14. Comparison Euro5 Diesel – Gas busses CNG Diesel Remarks Elimination Elimination NOx 75 t p.a. without filter (INFRAS) > 40 t p.a. > 30 t p.a. BERNMOBIL’s share on traffic NOx BERNMOBIL Reduced to 9% Reduced to 12% emissions in Bern before biogas busses share was 15% Particle mass irrelevant irrelevant Before gas, 1.07 t p.a. were emitted PM10 Reduced by 1 m kg biogas (approx. 30 busses) CO2 eq. Same as today 2000 t CO2 p.a. CO2-neutral, Biogas from WWTP Noise approx. 63 dB approx. 66 dB With low exhaust Ammonia (Urea) None temperature existing Source: INFRAS 14
  15. 15. Comparison of different bio- fuels How far can a car run with different biofuels produced on 1ha of land 15
  16. 16. Bus filling stations 16
  17. 17. Experience with gas busses During 15 months the bus operation of 45 buses were carefully monitored: • In total, 26 different recurring problems were encountered.The seven most 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 time The new buses will be delivered by Mercedes 17
  18. 18. Development of vehicles Personal cars Busses Target Biogasmax Plus 100 70 Status end of 2006 334 32 Status end of 2007 647 45 Status end of 2008 950 45 18
  19. 19. Increase of private cars Because our planet has no air conditioning I reduce CO2 with IQ I boroughed the world but I bought my NGV Campaign 1: Testimonials 19
  20. 20. Increase of private cars Campaign 2: Are you old fashioned? 20
  21. 21. Promotion of private cars 80’000 flyers to households with special offer 24% reduction 12.5% reduction 21
  22. 22. The fuel price helps as well ! 22
  23. 23. New public filling stations The Biogasmax target was 7 filling stations in the Berne region Achieved are Public Private BRM 2008 8 1 3 2009 11 2 4 23
  24. 24. The end Biogasmax in Berne: A great success! 24
