A flexible water battery and the latest hybrid tower technology in focus at trade show Husum Wind
Max Bögl Wind AG is setting new benchmark standards. With hub heights of up to 178 meters, four hybrid towers, each with 3.4 megawatts (MW) capacity will set a new world record as part of a pilot project in Gaildorf from October 2017. The wind farm is combined with a pumped-storage power plant. This creates a natural energy storage facility based on water, known as the “water battery”. It acts as a short-term storage facility and helps to maintain stability of the grid. The flexible water battery and the latest hybrid tower technology for wind turbines are the focus at the Max Bögl Wind AG stand at this year’s Husum Wind, in hall 2, stand 2D11.
Water provides power
The idea behind combining two renewable energy sources in Gaildorf is that wherever concrete foundations are installed on a mountain, they can also be developed as water reservoirs. Thanks to the water storage facility in the tower foundation, added meters of hub height are obtained, thus leading to a higher wind yield. PE pressure pipes connect these upper reservoirs with a hydroelectric power station and the corresponding lower reservoir 200 meters below in the valley. The water battery reduces the need for chemical large-scale storage facilities and offers a natural alternative. Complex approval procedures, which are required for conventional pumped-storage power plants, no longer apply, since with the water battery, no large-scale intervention in the natural environment is required.
Multimedia presentation of the method of functioning
At the Husum Wind trade fair, Max Bögl Wind AG will offer visitors the chance to experience the water battery at stand 2D11 in hall 2. Using a multi-touch panel, visitors can obtain information about the storage solution, with 3D views of Gaildorf as an example. The precise method of functioning of the water battery and the economic opportunities for electricity marketing are also clearly explained.
The company behind the project is Max Bögl Wind AG, an affiliate company of Max Bögl. The corporate group from Sengenthal near Neumarkt in Bavaria is one of the largest German companies in the construction industry. It has been active in the wind sector since 2010, and has now become the market leader in the production, supply and installation of hybrid towers with hub heights over 130 meters.
About Max Bögl Wind AG
Using renewable energies more efficiently and forwarding the energy revolution. This is the principle behind Max Bögl Wind AG with its innovative technology solutions. The company is the market leader in Germany for manufacturing, delivery and erection of hybrid towers for hub heights of 130 meters and above, and holds the record for the highest wind turbine tower with an hub height of 164 meters. Max Bögl Wind AG sets also new innovative standards in the energy storage industry. With the water battery, an entirely new type of flexible and small pumped-storage power plant has been developed which for the first time combines renewable energies with large-scale storage facilities. Max Bögl Wind AG is an affiliate company of Max Bögl. The corporate group from Sengenthal near Neumarkt in Bavaria, is one of the top ten largest German companies in the construction industry, and has been operating in the wind sector since 2010. Founded in 1929, the family-owned company with around 6,000 employees worldwide has an annual turnover of over 1.6 billion euros.
