Congratulations to all award winners and thank you for your pioneering spirit in expanding bioenergy.
Bioenergy award for future-proof biogas plants
Communication on the bioenergy award from the Specialist agency for renewable raw materials from the 14.11.2012.
Exemplary, exemplary and future-proof: Within the framework of the funded by the Federal Ministry of Food, Agriculture and Consumer Protection through the Agency for Renewable Resources (FNR) and the Kuratorium für Technik und Bauwesen in Landwirtschaft eV (KTBL) federal competition "Model solutions for future-proof biogas plants", three biogas plants from Bavaria and Lower Saxony were honored at the BioEnergy Decentral in Hanover on November 13th. Biogas plants were in demand, which, thanks to innovative process technology, efficient biomass utilization, economy and environmental friendliness, are model and exemplary. During the selection, attention was also paid to technical suitability, integration into the overall operation and the agricultural structure. Particular attention was paid to a high overall efficiency, with special attention to the sensible use of waste heat.
The award winners were honored with a certificate, a biogas sticker and prize money.
The award-winning systems are briefly presented below. The booklet accompanying the competition "Clever farmers give gas - model solutions for future-proof biogas plants 2012" (order no. 40097), which was published by the KTBL, provides detailed information.
Bioenergy award: Bio Energie Hofguträder GmbH & Co. KG, Bastheim
The biogas plant of Bio Energie Hofguträder GmbH & Co. KG has an installed electrical output of 250 kWel and is part of an ecologically managed family business. Around 80% of the substrates used are grass clover and pig manure. The remaining 20% is made up of maize, rapeseed GPS and low-quality grain. Most of the heat generated is supplied to public institutions and commercial enterprises and also for drying grain and Wood chips used on the company premises. At times of high heat demand, a biogas boiler is activated to ensure security of supply in the local heating network. Of particular note is the particularly high proportion of clover grass of 50%. The neighboring clover grass companies receive a nutrient balance through the return of the digestate. As a result, these organic farms have a high-quality manure available at the time they are needed.
Bioenergy award: Agrokraft Streutal GmbH & Co. KG, Unsleben
Agrokraft Streutal GmbH & Co. KG operates a biogas plant with an installed capacity of 889 kWel combined with a biogas processing plant with a capacity of 700 mn³ Raw biogas to biomethane per hour. 46 farmers are involved as partners in this system concept. Maize silage, whole grain plant silage (GPS) and manure are used as substrates. The CHP of the first plant supplies the heat for gas treatment using amine scrubbing and supplies a local heating network and a nursery. With an exhaust gas aftertreatment system, formaldehyde and methane emissions from the CHP plant are largely eliminated. To reduce the proportion of maize, farmers carry out trials and fermentation tests Streaky Silphie and Szarvazi grass through. In addition, they create flower strips that contribute to increasing biodiversity and improving the landscape.
Bioenergy award: Agrogas & Wärme GmbH & Co. KG, Malstedt
18 farmers are shareholders in Agrogas & Wärme GmbH & Co. KG. The installed electrical output of the plant is 1250 kW, the capacity of the processing plant 900 mn³ raw biogas per hour. Pig and cattle manure as well as maize silage, grass silage and Sugar beet used. The proportion of manure is 27%. A total of 5 CHPs are operated with 250 kWel each, 2 of which are at the plant site. Their waste heat is used on site for fermenter heating and gas treatment using amine scrubbing. 3 satellite CHP units supply the nearby town of Malstedt and 2 farms with piglet production and holiday apartments with heat. The biogas plant is an important component of the bioenergy village of Malstedt and thus also contributes significantly to the promotion of the village community.
Two of the award-winning biogas plants were built by the plant manufacturer MT-Energie. Here you will find the Press release on the bioenergy award the company.
Göttingen relies on bio-heat and is recognized as an energy community
Communication on the bioenergy award from the Agency for Renewable Energies (AEE) dated November 16, 2012.
In the university town of Göttingen in Lower Saxony, combined heat and power plants (CHP) supply households with bioenergy from the region via district heating networks. In the future, the networks will be expanded bit by bit. The city has been recognized as an “energy community” for its commitment. With the title, the Agency for Renewable Energies honors exemplary municipal energy projects and places them on the information portal Municipal renewable in detail.
“As a larger city, our options for using renewable energies are of course more limited than in the country, because we only have a limited amount of free space. We can do more by increasing efficiency. In Göttingen, however, it is important to us that both go hand in hand, ”explains Mayor Wolfgang Meyer. "We are also in exchange with the district of Göttingen. The cooperation gives us additional design options. ”The joint energy agency Region Göttingen also networks municipalities, farmers, companies, citizens and the scientists at the University of Göttingen.
The district heating in Göttingen is also partly supplied from the region: raw biogas is transported from an installation in neighboring Rosdorf to Göttingen via an eight-kilometer pipeline. There it flows into three new 650-kilowatt CHP units, which are connected to the largest district heating network in the city center and generate electricity and heat using cogeneration.
“The greatest potential for the use of district heating lies in densely populated inner-city areas, where it is otherwise relatively difficult for renewable energies. We therefore want to significantly expand district heating in the historic city center ”- reports the head of the municipal specialist service for climate protection and energy, Dinah Epperlein.
The city had a model project investigate how CO2-free energy supply is also possible in the historic city quarter at the botanical garden. The result: Without impairing the listed roofs and facades, 40 percent of the heat consumption can be saved through renovations. When all households are connected to the district heating network, another can be used Biogas CHP (combined heat and power plant) completely save the remaining emissions - the demand would also be met in the electricity sector. "With district heating, we can carry renewable energies into the city," says Epperlein. "For the implementation of the energy transition On site, energy efficiency and renewables have to complement each other in densely populated cities, ”says Nils Boenigk, project manager“ Municipal Renewable ”at the Agency for Renewable Energies. "The Göttingen Energy Community uses efficient biogas power plants, district heating networks and good cooperation with the district to meet this challenge."
