Pioneer projects Fairs

Pioneer projects Fairs and conventions From a nursery school built according to passive house guidelines to a renovated retirement home that became a model of energy efficiency, more than twenty exemplary Stuttgart Region projects are now featured online at www.zukunftsenergien.region-stuttgart.de (only in German) A fermentation plant using a fuel cell Bio-waste optimally used for energy Today, organic waste can no longer be used as landfill but has to be processed instead. Böblingen County's solution is to make energy-rich biogas out of its biowaste in its own fermentation plant in Leonberg and then feed this biogas into a combined heat and power plant to produce electricity and heat. Some 30,000 t of bio-waste are processed annually in this plant. The 8.2 million kWh of electricity made each year in two combined heat and power plants is ultimately channelled into the public grid. This amount is enough to supply some 2,300 households with all the electricity they need for a year. Some of the biogas made here ends up in a special demonstration plant that is the world's first facility to use a molten carbonate fuel cell (Hot Module) to convert biogas into electricity and heat. Large photovoltaic power plants in the Stuttgart Region Lapp Kabel, one of the leading suppliers for the photovoltaic sector, is showing others the way. The company's own logistics centre at their headquarters in Stuttgart-Vaihingen now has a solar power plant heating the centre's 4,500 qm of floorspace. The installation on the Lapp logistics building is the second largest such plant in the Stuttgart Region. Only the solar plant on top of the DaimlerChrysler engine factory in Stuttgart is larger. A photovoltaic power plant with a surface area of 2,000 qm has also been installed on the roofs of a public housing project in Geislingen an der Steige. Providing solar heat locally for the new housing development Rotkehlchenweg in Fellbach The city power company in Fellbach opted for a new and unconventional solution for its new neighbourhood development project Rotkehlchenweg. This applies not only to designing buildings for minimal energy consumption but also to the centralized heating solution for the entire neighbourhood. The overall energy concept was developed by the Steinbeis Transfer Centre for Energy, Building and Solar Technology (www.stz-egs.de) in Stuttgart. Three solar power plants and a condensing boiler provide the neighbourhood with heat. An exemplary energy concept for the “Museum Ritter” in Waldenbuch Ritter, the chocolate maker with a penchant for squares, designed its new “Museum Ritter” according to ecological principles. In order to use energy as responsibly as possible, they chose to exploit solar energy, biomass and geothermia. They have also managed to use 100% regenerative energy to cool the air. A thermic solar power plant on the roof of the museum provides 40% of the heat needed, an additional 40% comes from hot underground water that is circulated through 73 upright pipes located inside the building's pilings. Aside from these measures four boilers that burn wood-pellets also provide energy. MUSEUM RITTER with Squares of Light by Waltraut Cooper, 2006, © VG Bild-Kunst, Bonn “CEP – Clean Energy Power ® ” Stuttgart The fair “erneuerbare energien” continues in 2008 under the new name “CEP – Clean Energy Power ® ”. The fair offers a broad spectrum of topics related to renewable energies, rational use of energy and energy-efficient building and renovation. Half-day and whole day conventions and workshops inform participants about new scientific and practical developments. The balance: 250 exhibitors, 8,000 fair visitors and 1,000 convention guests. The relocation of the fair from Böblingen to Stuttgart in 2007 is expected to trigger yet more growth. www.erneuerbareenergien.com/english “Pellets” now with a European dimension The trade fair Pellets, the accompanying industry forum of the same name and the exhibition with a total floor space of 5,000 qm demonstrate the increasing internationalisation of the wood pellets industry. The trade fair alone brought 420 visitors from 21 countries to Stuttgart. The organisers later renamed it accordingly: In the future the trade fair focusing on heating with wood pellets will be called “Interpellets”. www.pelletsmesse.de f-cell – from R&D to the market Over time the f-cell fair has developed into one of Germany's most important events for fuel cell technology. Some 600 participants from 20 countries take part in the many individual events. F-cell is an important link between science, manufacturers, suppliers and users. In the beginning quite small, the fair gets bigger every year. In 2006 more than 50 exhibitors came to the fair. www.f-cell.de/english

Projects and initiatives The Cluster Initiative of the Stuttgart Region Economic Development Corporation (WRS) The WRS initiates and manages networks like the two that focus on biomass and fuel cells. The WRS's other important tasks include soliciting grant money to realize specific projects and providing interested groups with appropriate information. For example, they compile and distribute a fuel cell source book, dispense information about how biomass can be used as fuel, publish an industry guide in the internet about clean energy sources, and maintain a solar roof exchange platform where solar investors can find roof space available in the region for investment purposes. Beyond that, the WRS' experts support businesses by offering unbiased consulting free of charge about all aspects of choosing a new location, whether expanding or building anew, whether starting a new business or seeking venture capital. EU Project POLYCITY Three large housing development projects in Germany, Spain and Italy are being supported as part of the POLYCITY project. The main focus is on optimising energy consumption and using renewable energy for fuel. The German project area is the Scharnhauser Park neighbourhood in Ostfildern. Here an exemplary ecological residential area is being developed over an area of some 140 ha. Only buildings that conform to low-energy building specifications are allowed. A central block heat and power plant that runs on wood chips supplies most of the energy required. www.polycity.net Centre for applied research in universities – sustainable energy technology The zafh.net is one of three centres of excellence in the state of Baden-Württemberg. The participating universities of applied sciences all conduct research on new technologies for the year-round use of renewable energies for heating and cooling and to make electricity. Heating and cooling buildings sustainably is a particularly innovative area of research that has to do with developing solar thermal refrigeration machines, exploring shallow geothermic sources and investigating the possibilities of cooling passively. It is all about finding economical and energy-efficient solutions and getting these developed to the marketable stage. www.zafh.net Regional Competence and Innovation Centres in the Stuttgart Region The only way to reach the goals of using more renewable energies and getting fuel cell applications to the marketable stage faster is by supporting intensified cooperation between businesses and research institutions. An especially good way of formalising this kind of cooperation is through regional competence and innovation centres. Networks like these use regional funding sources to improve communication and exploit synergies between businesses, research establishments and universities working in related technology fields.
