1 Field Trip in Austria October 10 th 12 th,

2 Aim of the Field Trip During the projects activities it has been observed that in Poland there are major prejudices under the population about the implementation of bioenergy. Though the political targets are high, the implementation of bioenergy is lacking far behind. It seems very important for the 4Biomass project partners to demonstrate the advantages that come along with bioenergy investments. This field trip was part of the projects work description and crucial for preparing investments - the core output here in this workpackage. The Field Trip provided the opportunity to get to know by the stakeholders local/national conditions and regulations, learn problems, which occurred during the operation of the units and exchange experiences from their management. This knowledge may foster the sustainable exploitation of biomass within the EU by eg. creating more effective political measures. It appeared very beneficial to all project partners to bring stakeholders from Poland to Austria in order to show how bioenergy can bring added value for the people that live there. The participants were the representatives of the communes from different part of Poland in order to disseminate the knowledge gained during the Tour in different Voivodships. Selected were the decision makers, including mayors, council members or presidents of municipal companies, who may directly influence on the local energy strategy plans and implement technologies presented in Austria. During the Field Trip from large to small scale units were visited. All site visits are presented in the details below. 2

3 Location #1 Obermarkersdorf (biomass district heating and solar thermal energy) Chairman of the co-operative Werner Grolly, Phone: General Information capital expenditure: 1.2 Mio ,000 for the second boiler annual throughput: approx. 3,000 m³ of loose material, wood chip The boiler room is situated on the periphery of the village, in the vicinity of the church in the direction to Schrattenthal. Energy production: The system for distant heat distribution in Obermarkersdorf provides heat and hot service water for 95 clients. During winter, the boiler with an output of 840 kw is used, which is supported by operation of another boiler with an output of 340 kw and solar device for covering peak loads. During summer months, primarily the solar device, with its equalizing reservoir and volume of 80,000 l, where hot water intended for use is stored, is used for preparation of hot service water, while consumption peaks are covered again by the boiler with an output of 340 kw. The original idea to build the distant heat distribution system came from then mayor of the Obermarkersdorf municipality and the present chairman of the cooperative, Mr. Werner Grolly. He was thinking about possibilities of closing an ecological cycle within the village for several years. The municipality owns 350 ha of forest and forests with a total 3

4 area of 1,200 ha are located on the territory of the municipality, thus, these are ideal circumstances for building the distant heat distribution system fuelled by wood chip. Combined production of heat for distant distribution fuelled by wood chip and solar energy is a pilot experiment, which is unique in Austria for the time being. Economics Operator: FWG Obermarkersdorf reggenmbh has 95 members with participation certificates. Capital expenditure: 1.2 Mio ,000 for the second boiler Cash resources: Customers consuming heat are paying a connecting fee and they are getting settlements according to consumed kwh quarterly. Each customer is paying a basic fee according to calculated thermal load. Cash expenses: The plant covers costs for its functioning by its operation; the original loan for this purpose is almost fully repaid. Technical Data 1 boiler fuelled by forest wood chip with a thermal output of 840 kw, 1 boiler fuelled by forest wood chip with a thermal output of 340 kw, 1 equalising reservoir for hot water with a volume of 80 m³. material usage: 4

5 approx. 3,000 m³ of loose material, forest wood chip from the territory of the municipality Residues: Produced ash serves as valuable fertilizer in agriculture. Location #2 Waldland Oberwaltenreith, Farmers-cooperative with about 750 members for production and marketing of many farmers-products like plant-oil, straw and flax for thermal insulation, linen, flax, clothes, food, etc. Vermarktungs GesmbH Oberwaltenreith 10 A-3533 Friedersbach Tel: +43/2826/ Fax: +43/2826/ General Information Farmers-cooperative with about 750 members for production and marketing of many farmers-products like plant-oil, straw and flax for thermal insulation, linen, flax, clothes, food, etc. 5

6 Waldland is a company, which processes and promotes vegetable and animal specialties. It is a network, which connects many market participants. Waldland is strongly bound to the Waldviertel. The binding starts at its members, which are spread across the whole Waldviertel. The spread of supplying farms is very important for the success of Waldland. The members sign a contract with Waldland to produce a special crop or breed animals. With their identification number they grant the fixed Waldland quality. A great number of the members cultivate according to the rules for organic farming. A further specialty of Waldland is processing the raw materials at the Waldland site. Own equipment allows an immediate and flexible adaptation to new raw materials and products. Therefore the increase in value stays in the region. Location #3 Hafnerbach (Primary school Hafnerbach, Museumsstraße 43, 3385 Prinzersdorf) General Information Small scale wood-fired biomass district heating plant realised and operated by BeNö. Regional added value: EUR per year CO2-saving: kg /year Construction:

7 Operators: community Bioenergie Nö Hafnerbach consisting of 5 farmers and foresters Supplied buildings: municipality office, primary school, kindergarten, parsonage and church Heat consumers overall: 4 Investment costs: EUR excl. VAT Biomass boiler: 200kW with 5m rotation auger Heating output objects: 230 kw Heat storage tank: 4.000l Heat district grid: 255m Fuel wood: wood chips, W30, ca. 600 bulk qm/year Wood chips storage: ca. 100 qm Location #4 Straw fired district heating plant Stetteldorf General Information address: A-3430 Stetteldorf telefon: +43 (0) oder +43 (0) fax: +43 (0) gemeinde@stetteldorf-wagram.gv.at homepage: business management: Hermann Resch general management: Hermann Resch state: Lower Austria type of energy: biomass 7

8 capital expenditure: approx. ATS 37.5 Mio. (approx. 2.7 Mio.) annual throughput: approx. 2,000 t of straw/a annual production: - annual electricity production: - annual heat production: approx. 5,000 to 6,000 MWh/a input: Straw operator: Members of FWG Stetteldorf The plant for distant heat distribution is situated on the right side above the municipality directly next to Wagram. Thanks to chosen construction of massive concrete and wood, the plant fits harmonically into the surrounding landscape. At the beginning of 2007, approx. 250 households and public buildings, such as a school, town hall, kindergarten, vicarage hall etc. in three cadastral municipalities were connected to the piping with a length of approx. 7 km. Energy production: Straw is bought from farmers, members of the cooperative, left loosely on fields, while it is compressed, loaded and transported to the straw storage by big compressors owned by the cooperative. Average weight of a straw bundle is approx. 300 kg. With 2,000 tons of straw, this corresponds to approx. 750 ha of field sown by grain crops. The fuel is fed to the straw-fuelled boiler by automatic tossing device from the storage with a capacity for weekly consumption. Straw bundles are filled to this storage by a stacker. Prior to burning in the straw-fuelled boiler Hollensen Biomaster, straw bundles are fully automatically cut up. The heat for heating purposes and preparation of hot service water is produced only during heating season. 8

9 When there is approx. 15 t (corresponding to 300 t of straw, considering 5 % of ash or approx. 1,000 bundles á 300 kg) in the pit for ash, approx. 40 m³ of water is added, mixture is mixed by a mixing device, pumped into the reservoir for liquid manure and evenly emptied to fields as fertilizer without burdening the environment with dust. Connections are realized only with the condition that there will be contractually an agreed minimum consumption on a level of 2/3 of calculated connecting value. In such a manner, the cooperative for distant heat distribution ensures a fixed basic revenue. Each consumption place can be technologically monitored online and at the same time, remotely controlled. Also customers can control their connection themselves remotely by means of internet. Contrary to oil, gas, electric energy or coal, there was no increase of tariff prices for heat consumption for the time being. Assumed costs for construction were observed and the plant is even more economical as stated in the original calculations. Economics Operator: Members of FWG (cooperative for distant heat distribution) Stetteldorf am Wagram. Capital expenditure: approx. ATS 37.5 Mio. (approx. 2.7 Mio.) Cash resources: 0.05 is charged for each kwh up to the limit of minimum consumption. Each kwh above the limit of minimum consumption is charged by a rate of Costs for heating are maintained at the same level already for 13 years. Cash expenses: Farmers, being members of the FWG Stetteldorf cooperative, get payment for loose dry straw of around 30 per ton + 12 VAT. 9

10 Technical data 2 covered storage halls for straw, each with an area of 1,100 m² (6 m high and 20 m wide) and additional 1 x 550 m², also roofed premises. 1 fully automatic jib with grab for transporting straw bundles to the plant. 1 fully automatic cutting device for cutting up bundles. 1 straw-fuelled boiler Hollensen Biomaster with an output of 2,500 kw with fully automatic tossing device. 1 oil-fuelled boiler Hollensen Biomaster with an output of 2,000 kw and the oil tank with a volume of 20,000 l. Material usage: approx. 2,000 t of straw/a Water demand: In small volumes for carrying away ash. Residues: Produced ash is filled into reservoir for liquid manure and applied in liquid form as fertilizer. Annual operation hours: approx. 2,000 to 2,200 hours of full load Annual production: approx. 5,000 to 6,000 MWh of heat per year During the visit, the meeting with Stephan Pernkopf, provincial governor for agriculture, forestry, environment and energy in Stetteldorf took place. 10

11 Location #5 Klosterneuburg: presentation of BeNö (Bioenergy Lower Austria); Cooperative of bioenergy-experts and farmers for planning, building and operation of small biomass district heating plants, owned preferably by farmers. Currently operating 46 biomass district heating plants in the 50 to 300 kw range. General Information In Klosterneuburg, the BeNö (Bioenergy Lower Austria) the Cooperative of bioenergyexperts and farmers for planning, building and operation of small biomass district heating plants, owned preferably by farmers has been presented. BeNö currently operating 46 biomass district heating plants in the 50 to 300 kw range. Location #6 Biomass-heating plant in monastery of Klosterneuburg incl. ORC The monastery of Klosterneuburg has decided to replace the heating of the monastery buildings, which is partially ensured by tiled stoves, by central heating fuelled with biomass. The assessment of the heating requirements of the monastery and of the neighbouring recreational centre "Happyland" resulted in an annual heat requirement of 11,550 MWh per year. 11

12 A 2.5 MW biomass boiler was constructed as well as an electricity and heat generation by an ORC process producing 200 kw of electrical energy and 1.0 MW of heat. The heat load is covered by the base load supply of the ORC process, the trapezoidal load is covered by the 2.5 MW biomass boiler and a 4.0 MW gas boiler is provided for standby and peak load operation. The ORC process is maintained by a 1.2 MW thermal oil boiler. A flue gas condensation system was installed in order to increase energy efficiency, to reduce dust emissions and to avoid the creation of a vapour plume at the chimney flue outlet. The architectural concept was a special challenge for the mechanical engineering design of this biomass heating plant. Heinz Tesar, the winner of the architectural competition, decided for an "invisible" architecture: the entire facility to be constructed (heating plant, biomass storehouse, wine cellar, parking garage for buses and private vehicles) is located under a gently rising hill. Thus the overall appearance of the architectural ensemble of the monastery is preserved. SUMMARY The study tour has had, no doubt a huge impact on the environmental awareness of the participants of the study tour and their understanding of the benefits of a local use of biomass for heating purposes. One of the most important results has been seeing in practice the organisational solutions that could be possibly applied on Poland. The participants maintain contacts with Polish organisers of the study tour regarding the possibilities of designing biomass projects using the Austrian experience. The most advanced are the plans to invest in biomass heating in the commune of Jerzmanowice- Przeginia, where several concrete proposals are being elaborated and in the city of Brzesko, where the local District Heat Company together wilt the City Council has started drafting plans to convert one of the schools in their area from fossil fuel to locally harvested biomass. Several meetings including site visits. with participation of the AGH 4 Biomass team have taken place. Evaluation by participants The filed trip was highly rated by participants, both in the aspect of organisation of the event (72,22% v. good and 27,78% good rates) and the facilities selected for visits (94,44% v. good and good rates). In the evaluation forms participants of the field trip declared plans for investments in biomass energy projects amounted at million EUR and creation of jobs. 12
