3 Agenda Background Biogas drivers Biogas injection experience Bio-SNG Conclusions 01 December 2010, E.ON, Page 3

4 Agenda Background Biogas drivers Biogas injection experience Bio-SNG Conclusions 01 December 2010, E.ON, Page 4

5 European outlook - growing natural gas market but decreasing production Source: Eurogas 5

6 Swedish Government climate policy Year 2020: 50% of Swedish energy use be based on renewable sources CO2 emission reduced by 40% Energy efficiency increased by 20% 10% renewable sources in transport sector Year 2030: transport sector independent of fossil fuels Year 2050: net contribution of CO2 shall be reduced to zero

7 Agenda Background Biogas drivers Biogas upgrading experience Bio-SNG Conclusions 01 December 2010, E.ON, Page 7

8 National roadmaps for sustainable gas system (SE) 2 billion m ~10% biomethane billion m 3 /year (510 TWh/year) Total investment demand >60 billion (UK) 5-15% biomethane 2020 (DE) 6 billion m billion m (NL) 15-20% biomethane 2030

9 European drivers for biomethane Energy tax directive, 3-4 c/kwh for petrol/diesel Carbon emissions trading system transport sector not included >20 MW prices /ton National incentives (UK) Renewable Obligation Certificates Renewable transport Fuels Obligation (SE) Tax exemption (DE) Renewable electricity, (NL) 15-20% biomethane 2030 Feed in tariffs

10 Swedish political framework Gas grid injection Tax exemption for biogas in the gas grid Trading of biogas to specific customers CO 2 -based road tax 40% reduced tax on company CNG/biogas vehicles Climate investment program Environmental policy for governmental organizations (85% env. Vehicles 2007)

11 Agenda Background Biogas drivers Biogas injection experience Biogas as vehicle fuel Conclusions 01 December 2010, E.ON, Page 11

12 Biogas upgrading plants in Europe Total number of plants: 104 Total injection capacity: > m 3 /h Annual production capacity: 3,2 TWh Annual natural gas consumption: 5100 TWh (D)35 (NL) 4 (FR) 3 (CH) 15 (SE) 38 (AT)5 (ES) 4

13 Why upgrade biogas? Requirement of gas applications prevent mechanical wear prevent corrosion Rise calorific value of the gas increase driving distance for vehicles and ascertain function of gas equipment Standardization of the gas 01 December 2010, E.ON, Page 13 even fuel quality

14 Swedish standard for biogas as vehicle fuel, 1999

15 Biogas upgrading - Water scrubber systems CO 2 -absorption in water Suitable for sites with water readily available Methane losses has to be controlled Growth on packing requires attention Photo: BioMil

16 Biogas upgrading - PSA Pressure Swing Adsorption Adsorption 4 bar Desorption in vacuum Activated carbon or zeolites Poisoned by hydrogen sulphide

17 Biogas ugrading - Chemical absorption Chemical reaction Liquid reacts chemically with carbon dioxide Alkanolamine, ex. MEA Atmospheric pressure Regeneration through heating

18 Biogas upgrading - Cryogenic systems Technology still under development First Swedish plant now in operation Potential for CO 2 -recovery Methane may be produced in liquid form (LBG)

26 Feasibility of pressurized biomass gasification was demonstrated by E.ON in the Värnamo plant (6 MW el, 9 MW heat ) Test program concluded 1999 More than 3600 hours in Combined Cycle dmode About 8500 hours of gas production No negative effects on gasification, filter or gas turbine The result from Värnamo shows that gasification works 26

27 GoBiGas Phase 1, 20 MW Bio-SNG Existing wood pellets-fired boilers

28 GoBiGas project status October 2010 State funding 25 % of project cost, 222 MSEK granted from the Swedish Energy Agency under provision of approval by the EC, discussion ongoing. Gasification Cooperation between Metso Power (SF) and Repotec (AT). Basic Engineering being carried out Methanation Basic Engineering with Haldor Topsö (DK) Ground work and civil engineering Engineering and preparation for start of work at site 2010 Permits Applications for environmental permits and building permits for Phase 1 and Phase 2 Preliminary investment decision in June 2010 Plant in operation second half of 2012

30 Bio2G (Biomethane 2nd Generation) The Bio2G project comprises design, erection and commissioning of a biomethane plant with 200MW output (input: solid biomass) Planned start of construction 2013 Silo for moist biomass fuel Fuel dryers Gasification Flares ASU Methanation Planned start of operation 2015 Boiler house Silos - ash, bed material 350 m Discussions ongoing with possible partners

31 International outlook indicates several activities European Cooperation in Güssing through GoBiGas project GdF Suez is starting up a 7-year project (45 M ) aiming at developing the whole value chain from fuel supply to grid injection 3 years after E.ON Large European public funding schemes are aimed at large scale demonstration of renewables (NER 300) and reference plants for production of biofuel (EBTP, EIBI) MILENA Pilot plant operation and demonstration plant planned

32 Summary Drivers and political incentives essential for a positive development Several commercial techniques available for biogas upgrading Cost to upgrade biogas is c/m 3 cleaned gas Feasibility studies show that Bio-SNG production can be an interesting option with same subsidies as for biogas Bio-SNG production has definite benefits of scale (>150MW) Potential to build MW plants in Sweden based on present raw material supply => would cover major part of present natural gas consumption
