2 From Biogas to Biomethane through Hydrogen Utilization: a Real Case Scenario Daniele Pagani, Nordic Folkecenter for Renewable Energy dp@folkecenter.dk Community Power and Renewable Energy Storage in Denmark and in the EU 12 December 2016

3 3 Agenda Situation Description; Economic Consideration on surplus power; Technical & Economic Results of the study; The future; Conclusions;

4 4 How can we increase our energy production and at the same time reduce our CO 2 emissions?

5 5 Situation Description Wind turbine: Vestas V47, 660 kw Average production: GWh/year; Installation: 2000; Expected lifetime: Extra years; Biogas installation: 6000 m 3 /day (2 digesters x 3000 m 3 ); 65% CH 4 content; Approx. 4 GWh/year production; Input: 70 tons/day of waste; Waste Quantity (tons) Liquid slaughtery waste 25 Cow manure 20 Pig manure (local) 15 Straw from cow beddings 6 Other solid component 2-4

6 6 Situation Description The pig farm: Average consumption: 4-500,000 kwh/y Additional 50-60,000 kwh (August-October) due to ventilation of the harvest;

7 What does this have to do with storage? 7

8 8 Situation Description Upgrade biogas to 80-90% CH 4 and store it!

9 9 Why Upgrading Biogas? Before 1 January 2014: 2000: 0.10 DKK/kWh + Market Price = Max 0,36 DKK/kWh 22,000 full load h in 20 years; After: 0,023 DKK/kWh; Electricity produced with WT1: DKK/kWh Electricity produced with Biogas: Item Price (DKK/kWh) Biogas 25 Subsidy ( fluctuating) Subsidy (0.10 decreasing) Total price 1,23

10 The Upgrading Process Sabatier Reaction: CO 2 + 4H 2 CH 4 + 2H 2 O Increase CH 4 up to 50% = 2x CH 4 quantity More technical information: 1

11 The Upgrading Process Situation Specific 1

12 The Upgrading Process Situation Specific 1

13 The Upgrading Process The Electrolyzer 138,000 USD Consumption: 4.8 kwh/m 3 1

14 The Upgrading Process Technical Considerations Yearly production: 130,547 m3 Yearly consumption: 73,408 1

15 The Upgrading Process Technical Considerations 1

16 The Upgrading Process Technical Considerations +18,200 m 3 H 2 /year 1

17 The Upgrading Process Economic Considerations 1

18 The Upgrading Process Economic Considerations 1

19 The Upgrading Process Economic Evaluations Before Upgrading 1

20 The Upgrading Process Economic Evaluations After Upgrading 2

21 Danish Environmental Goals 2020: 50% Electricity from wind 2030: Coal plants and oil burners are phased out 2035: 100% Electricity and heat from renewables 2050: All sectors powered by renewables 2

22 Danish Wind Energy Situation MW installed wind capacity (2015); 42% of electricity production Highest amount of wind production per capita (852 W); 2

23 Danish Biogas Industry: A Growing Sector cattles pigs Tonnes/year 196+ Biogas plants installed; 95,8 MW installed (2015); GWh/year produced (2010); 2

24 Problems CH 4 content: 50-65% Low energy content More plants needed! CO 2 content: 35-50% Greenhouse gas Human impact is not reduced Global CO 2 Emissions (Million Metric Tonne/year) Trees needed to balance 1 year! 2

25 The Future 1.5 Million cars can be driven with Danish biogas potential; Farmer s truck consumption: 1.8 km/l Gas selling can be an additional revenue for the farmers 2

26 Conclusions Upgrading biogas can be used for: Green transport; Electricity production; Waste treatment; Heat production; Bio-fertilizer production; Additional advantages: Produce more gas with less installations; CO 2 reduction; Seasonal storage in national underground s storage facilities; 2
