Max Bögl Wind AG demonstrates its new power plant and storage concept at the Energy Storage Europe trade fair in Düsseldorf.

Max Bögl Wind AG will present its globally unique natural storage technology products at this year’s Energy Storage Europe trade fair in Düsseldorf. From March 13 to 15, the company will present its water battery in Hall 8b, booth E31.

The water battery from Max Bögl Wind AG is a completely new type of large-scale storage facility, which combines the production of electricity from renewable energy sources with a modern pumped storage hydroelectric power plant in a technically innovative manner. Proven converters from wind turbines are used in the pumped storage reservoir house in order to satisfy the grid code requirements of the grid operators and efficiently provide balancing energy. Max Bögl Wind AG has succeeded in using a series wind energy product in a hydroelectric power system for the first time. The company is also breaking new ground in the development of polyethylene (PE) connection pipes between the water storage facility and the pumped storage hydroelectric power plant. The pressure pipe has been developed in-house in order to establish location independent production and develop a series product that can be efficiently used worldwide for future water batteries.

The first water battery project is currently being developed in Germany at Gaildorf near Stuttgart. It consists of a wind farm with four wind turbines – among which is the highest wind turbine in the world at 178 meters – and a pumped storage hydroelectric power plant with an installed capacity of 16 MW. The new storage concept uses the tower base of the wind turbines as water storage facilities with a storage capacity of 70 megawatt hours. A penstock connects them with a hydroelectric power station and its lower reservoir located 200 meters further down the valley.

“The water battery is a natural storage facility that stands out due to its durability and high degree of flexibility,” says Jürgen Joos, CFO at Max Bögl Wind AG. Josef Knitl, a Board Member of Max Bögl Wind AG, also adds: “Without large-scale and forward-looking projects and ideas, the energy transition in Germany cannot succeed. With the water battery and hybrid towers, we are making wind energy a more attractive and efficient source of clean energy while also setting new records.”

About Max Bögl Wind AG
Using renewable energies more efficiently and forwarding the energy transition. 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 a hub height of 178 meters. Max Bögl Wind AG is also setting 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 10 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. http://www.mbrenewables.com/
