1 USE OF BIOGAS AND BIODIESEL IN SLOVENIA Tomaž POJE, M.Sc. Agricultural Institute of Slovenia Department of Agricultural Engineering Conference: BIOMASS IN SOUTH EAST EUROPE Berlin,

2 My presentation consists of two parts: - Biodiesel production (Surce: Agricultural Institute of Slovenia) - Biogas (Surce: Agricultural Institute of Slovenia)

3 BIODIESEL PRODUCTION 1 producer of biodiesel in Slovenia (PINUS RAČE) 9000 tons per year New factory in 2010 with the production of tons of biodiesel per year

4 Decentralised oil-mill

5 Usage of biodiesel Up to 5 % of biodiesel in normal diesel fuel (without declaration) 1 filling station with 100 % biodiesel (B100) in Ljubljana, 400 l B100 per month (It was closed in August 2009)

6 SURFACE OF RAPE (ha) Raw material for biodiesel Domestic rape seed Foreign oil (rape oil, palm oil) Average yield of rape seed: 2,3 t/ha YEAR

7 Pure plant oil for vehicles Only a few vehicles (cars, off-road vehicles and tractors)

8 BIOGAS

9 Biogas from WWTP and landfill gas (Source: IJS-CEU, 2008) Six wastewater treatment plants (WWTP): Domžale- Kamnik, Kranj, Ptuj, Škofja loka, Velenje and Jesenice. Under construction are some new devices on central treatment plants. The total electric power is 2,1 MW. Three landfill sites of municipal waste - landfill gas: Ljubljana, Maribor and Celje. The total installed electrical power of all devices is 3,5 MW.

10 AGRICULTURAL BIOGAS PLANTS By the establishment of more appropriate purchase prices and premiums for qualified producers of electricity after 2002 the Government spurred the construction of agricultural biogas plants. In addition to slurry, they use other substrates, mainly energy crops that have a good recovery of methane or biogas.

11 The total electric power installed in cogeneration plants of agricultural biogas plants is 13.8 MW. The heat is used to heat the biogas plant (BP) and the nearby buildings, but currently it does not heat settlements. The last built BP is expected to emit the heat to nearby greenhouses.

12 Biogas plants must acquire the status of qualified electricity producers. Any such qualified electricity producer receives (received) the payment according to a single annual price of EUR per MWh of electricity produced. (old degree old system) He is (was) also entitled to a single annual premium, which is EUR per MWh of electricity produced. These figures are from for the year (old degree old system)

13 Map of agricultural biogas plants in Slovenia, state october 2009

14 "The association of biogas producers" was founded in the 2008.

15 Institute of the Republic of Slovenia for Vocational Education and Training Institute of the Republic of Slovenia for Vocational Education and Training, the central Slovenian institution dealing with development, research and counselling in the field of vocational and technical education prepared a professional standard module course Operator of biogas plant that would be taught in agricultural (biotechnical) schools. The choice of this module will be possible in the school year 2009/2010.

18 Thermal power rating of the cogeneration plant: 1200 kw Electrical power rating of the cogeneration plant: 1000 kw Generated electrical energy: 8 million kwh per year

19 Time of starting: March 2007 Type of corporation: Independent entrepreneur Amount of gas produced: m 3 per day Investment costs: EUR

20 Liquid pig manure: 3200 m 3 per year Grass silage: 3000 ton per year Silage maize: 7700 ton per year Maize grain (Corn Cob Mix): 500 ton per year Bunker silo: m 3 Silage is transported from horizontal silo with loader in the silage dosing system.

21

22 In the process of wet dosing the silage is mixed with pig manure. Wet dosage

23 Digester: 2 x 2200 m 3, second digester: 2 x 2200 m 3 Dige Gas storage tank: 2 x 1200 m 3

24 Pipes for biogas

25 Biogas is transported in tubes to the cogeneration unit with the engine of 1000 kw power.

27 Final storage tank: 6500 m 3 the new storage tank 1200 m 3 the existing storage tank (sump)

32 Statement of the operator (at the end of 2007): The option of biogas production from liquid manure in Slovenia has not been exploited enough so far. All the liquid manure ought to be included in the production of biogas. Positive experience gathered until now is a stimulation for a new investment construction of the next biogas plant in the surrounding of Lendava for which we have already collected the required documentation. The construction is planned for the year 2008.

33 FUTURE OF BIOGAS IN SLOVENIA Agricultural potential for biogas production (Source: Peter Pšaker, Agricultural Chamber, meeting of the advisory committee for the project BIOGAS REGIONS; AIS, )

34 AGRICULTURAL POTENTIAL for biogas - Livestock manure (cattle and swine liquid manure (slurry), chicken manure, manure) - Plant biomass (stubble and main crops on arable land, permanent pasture - grass)

35 Scenarios to calculate the potential - Scenario 1: The least interference with the primary agricultural production - Scenario 2: Increased livestock productivity and changes in dietary habits of people - Scenario 3: It is more advantageous for farmers to sell the plant biomass for biogas than for human food or animal feed

36 Potential of biogas from agriculture Slovenia Scenario 1 Scenario 2 Scenario 3 45,1 MW 61,7 MW 78,1 MW The largest share in the Pomurje, Podravje and Central Slovenian Region A greater number of biogas plants with the total power of more than 30 MW are being built, designed and located currently. (Source: Dušan JUG, meeting of the Advisory Committee BIOGAS REGIONS; 29/5/2009)

37 USE OF BIOGAS Currently, only to produce electricity and heat. It is possible to use biogas as a motor fuel in vehicles or in distribution of natural gas pipelines.
