1 Biogas in Denmark - status and framework conditions BIOGASS11 March Lars Rohold Danish Biogas Association

2 March In relation to the objective of 20 to 30% renewable energy in the EU there is a long way before biogas becomes more common to use as energy source. Source: European Environmental Agency Biogas as renewable energy in EU 2 We are here !!!

3 March Danish Biogas Association Renewable energy in Denmark Wind Heat pumps Waste Wood Straw Biogas

4 March Danish Biogas Association Biogas in the Danish Energy System n Biogas is a “Small player” n Renewable energy is depending on political will n Competition with other RE, Combustion and wind energy.

5 March Danish Biogas Association Renewable energy in Denmark Wind Heat pumps Waste Wood Straw Biogas ’11

6 March Nordic BIoEnergy Reference plant Endeavour of the Danish Energy Authorities: About 20 central biogas plants were built in the late 80s and early 90s. They represent a total unique international reference Central biogas plants in Denmark

7 March Danish Biogas Association Danish biogas plants Number of plants 21 centralized biogas plants 60 farm scale biogas plants Joint and farmscale biogas plants 2003 Manure t Organic residues t Total t

12 March Danish Biogas Association Danish energy sector From centralized power plants to decentralized production Centralized production in the mid 80’sDecentralized production of today Decentralized CHP Wind mill park Centralized CHP Legend:

13 March Danish Political Model n Biogas to Decentralized CHP for heat and power production n Subsidized by the electricity producer n Utilization of heat in the district heating (Only one “costumer” and only one “integration” ) Danish Biogas Association

14 March Danish Biogas Association Advantages of biogas plants n Greenhouse gas reduction u Efficient F heat and power: 220 % F transportation: 167 % u Cheap F 0 to 5 CAD

15 March Danish Biogas Association Advantages of biogas plants n Greenhouse gas reduction n Utilisation of organic waste u Win-win situation F increased gas production F tipping fee F reduced costs for industry u new types of biomass: F energy crops F animal by-products F glycerine from biodiesel Joint biogas plants 2002

16 March Danish Biogas Association Advantages of biogas plants n Greenhouse gas reduction n Utilisation of organic waste n Redistribution of manure u from F livestock farmers to plant producers F farm to field F tractors to lorries F km distance 10 km

17 March Danish Biogas Association Advantages of biogas plants n Greenhouse gas reduction n Utilisation of organic waste n Redistribution of manure n Organic fertiliser u declarated nutrient content u free of pathogens and weed seeds Total N:5,0 NH4-N:4,0 P:0,9 K:2,8 Kg/ton

18 March Danish Biogas Association Advantages of biogas plants n Greenhouse gas reduction n Utilisation of organic waste n Redistribution of manure n Organic fertiliser n Smell from slurry reduced u thinner liquid u disperses quicker into soil Wind direction Raw manure Digested manure 5 minutes 12 hours

19 March Danish Biogas Association Advantages of biogas plants n Greenhouse gas reduction n Utilisation of organic waste n Redistribution of manure n Organic fertiliser n Smell from slurry reduced n Improved nitrogen utilisation n Reduced risk of leaching n Separation of digested biomass u low technology u net energy surplus

20 March Biomass potential in Denmark n Overall inventory shows that there is enough biomass to hundreds of biogas plants 20 (All values in TJ)

21 March Political Energy Settlement (2004) 21 Energiforlig giver fremtidstro for biogas Fredag 2. april 2004 Med regeringens energiforlig i denne uge med alle Folketingets partier på nær Enhedslisten gennemføres omsider sidste års aftale om at sikre den danske biogas en afregningspris på 60 øre pr. kWh i 10 år frem.

22 March Danish Biogas Association Biogas production in Denmark

23 March Danish Biogas Association Biogas development Government January : Biogasproduction to be trippled before 2025

24 March Political Energy Settlement (2008) Danish Biogas Association Fakta: Energiaftalens hovedpunkter Her er de 14 hovedpunkter fra torsdagens energi-forlig, som alle partier undtagen Enhedslisten står bag. Af Thomas Djursing, fredag 22. feb 2008 kl. 10:32Thomas Djursing - Biogasanlæg – både gamle og nye - får en fast elafregningspris på 74,5 øre per kilowatt-time. (Kilde: Ingeniøren)

25 March Danish Biogas Association Payment for electricity from biogas Payment from All plants

26 March Political influence Show examples: With palyers in the business Danish Biogas Association

27 Sønderjysk Biogas- Vi gi’r byen gas! Præsentation for Energipolitisk Udvalg Torsdag den 15. januar 2009 Levering af biogas til naturgasnettet

28 Sønderjysk Biogas- Vi gi’r byen gas! Opfordring Afsætning af biogas til naturgasnettet bør kunne finde sted under samme vilkår som afsætning til kraftvarmeproduktion. Derved –skabes der bedre muligheder for biogas –skabes der mulighed for optimal udnyttelse –sikres den fremtidige udvikling

29 Sønderjysk Biogas- Vi gi’r byen gas! Hvorfor naturgasnettet? Afsætning via naturgasnettet giver optimal anvendelse af gassen – intet spild fleksibel placering – bedst mulig logistik udvidelsesmuligheder – sikret afsætning flere anvendelsesmuligheder for gassen

30 Sønderjysk Biogas- Vi gi’r byen gas! Hvorfor naturgasnettet? Afsætning via naturgasnettet giver mulighed for udvidelse af bestående anlæg intet ”monopol” for kraftvarmeværket biogas i tyndere befolkede områder total fremtidssikring

31 March Danish Biogas Association Government Green Growth Plan 2009 Promotion in biogas through n From currently 5 % to 50 % of manure into biogas in 2020 n Co-ordination plan for construction of biogas plants n Plan for integration of biogas into the energy sector n Obligation for municipalities to point out where to build plants n Distribution in natural gas grid on equal terms as direct co-generation n Equal opportunities for biogas to earn money as natural gas suppliers n Financing u 20 % construction subsidy (in total 300 mill. DKK from 2010 to 2012) u loans guaranteed by municipalities u capital from investors

36 March Danish Biogas Association Filling stations in Sweden Source: Swedish Gas Distribution Local grids Natural gas grid By truck

37 March Danish Biogas Association Transportation - Sweden

38 March Danish Biogas Association Transportation - Sweden

39 March Danish Biogas Association Sweden – gas utilisation (pct) Heat most important Transportation fastet growing

40 March Danish Biogas Association Norway - waste in 29 biogas plants Source sep. household/food waste Food waste retailers Food waste hotels & restaurants Slaughterhouse waste (cat. 2) Slaughterhouse waste (cat. 3) Fish waste (cat. 3) Fats - sewage in foodindustry

41 March Ecopro, Verdal Norway Total area 9000 m2 Start up Sludge March 2008, Food waste April 2008

42 March WASTE FEEDSTOCKS Food waste (source separated household waste) Approx t/a Sludge (from waste water treatment plants) Approx t/a ABP (has not started to receive ABP yet) Approx t/a (slaughterhouse waste and dead salmons from fish farms)

43 March Typical mass balance ProductI/OComments Biowaste1000 kgFood waste 70-82% Sorting reject+grit kgThis number can be improved with better participation Bio-fertilizer~300 kg Biogas at 60% CH m3150 m3 on pure biowaste kWh Electricity kWh 300 kWh on pure biowaste

44 March DIGESTATE – BIO-FERTILIZER The produced digestate (approx t/a) do not need to go through any maturing process At Ecopro they intend to distribute the organic bio-fertilizer to the agricultural sector and to the private sector.  Attractive bio-fertilizer due to: - 100% pathogen-free & nutritious - Minimal odour (smells like soil) - 30% DS content - < 0,5% plastic in weight Cambi bio-fertilizer as produced Scotland: Spreading the Cambi bio-fertilizer into grasslands

45 March Suggestions for Norway n Look at the neighbors (Denmark and Sweden) …do not repeat bad experience! n Find the political argumentation for Biogas in the RE strategy (…you need political support) n Calculate the economical “break even” for investment (…you need investors) n Find the biomass and waste available for biogas production (…you need biomass and preferably a “waste problem”, ex fish industry) n Recycling og Nutrients as a part of future strategy.
