Water Battery

One of the greatest challenges of the energy revolution is achieving flexible retrieval of green electricity. Here Max Bögl Wind AG and its Water Battery makes a real difference. Due to the innovative combination of renewable energy and a pumped-storage hydropower plant, a high performance storage solution for flexible energy supply has been created.

The Water Battery serves as short-term storage and makes a contribution to keeping the electric grid stable. Using peak shaving, load peaks can be lowered and power line-related grid fees saved. When needed, the pumped-storage hydropower plant can provide energy within 30 seconds and feed the stored energy into the grid.

Hybrid Tower System

The tower represents the core of every wind turbine, forming the steadfast link between the massive turbine technology and the natural force of the wind. Max Bögl Wind AG continues to enhance its Hybrid Tower System, making constant improvements to efficiency.

Its new Hybrid Towers now ensure hub heights up to 180 meters and can be built at a favorable price. Annual extracted power increases by 0.5 to 1 percent with every additional meter that a wind turbine gains in hub height. Less wind turbulence and, consequently, a significantly improved wind yield mean hub heights over 130 meters are ideal, especially in inland areas with lighter winds. This ensures a faster return on investment for overall projects.

The water battery as a natural energy storage facility: Wind energy technology used in a pumped storage reservoir

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."

World record for the energy transition

It’s official now: Max Bögl Wind AG has built the world’s tallest wind turbine in the town of Gaildorf near Stuttgart, Germany. Featuring a hub height of 178 meters and a total height of 246.5 meters, this wind turbine has set a new world record. The turbine is also part of a wholly unique power plant concept - the water battery.

More height, efficiency and power: That is the aspiration behind Max Bögl Wind AG and their hybrid towers for wind power plants. The pioneering spirit of this Bavarian company is now in full view in the town of Gaildorf near Stuttgart, home of the world’s tallest wind turbine. Located in the Limpurg Hills with a hub height of 178 meters and a total height of 246.5 meters, this wind turbine is a clear sign that Max Bögl Wind AG is pushing the boundaries when it comes to harvesting wind energy. This height record was achieved in part due to the natural water reservoir built into the turbine. The wind farm in Gaildorf is not just any wind farm, but one based on a totally new power plant concept - the water battery - a technological innovation that is setting new industry standards. For the first time ever, power generation from renewable energy is combined with a modern pumped-storage power plant. This new storage concept utilizes the foundation of the wind turbine as a water reservoir, which results in a 40 meter increase in the height of the turbine. This is hugely beneficial since each additional meter of hub height added to a wind turbine increases the annual energy yield by 0.5 to 1 percent. High hub heights mean less wind turbulence and significantly better wind yield, especially for inland locations with weak wind conditions.

The world’s tallest wind turbine is part of a wind farm that consists of four wind turbines with hub heights ranging from 155 to 178 meters. Equipped with powerful 3.4 megawatt (MW) generators from GE, they will begin supplying clean energy to the German power grid in spring 2018. "Our 3MW category platform is extremely flexible and optimized for high energy yield. We are very happy that our customized solution for the GE 3.4-137 has helped to achieve this record," says Andreas von Bobart, General Manager of GE Renewable Energy Onshore Wind Deutschland. It is estimated that more than 10 gigawatt hours will be generated per year, which is enough electricity to power 2,500 four-person households. Max Bögl Wind AG is thus playing its part in making sure the energy transition succeeds. After all, the stated goal of the German federal government is to increase the share of renewable energy sources for power generation to 50 percent. It currently lies at 38 percent. "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," remarks Josef Knitl, Board Member at Max Bögl Wind AG.

The mayor of Gaildorf, Frank Zimmermann, also adds: "In our town and throughout the region, we are investing in our common future in a very ambitious yet sensible way. Thanks to the innovative power plant concept, we are proud to be at the forefront of the energy transition - one of the most important transitions of our age."

Innovative power sources and storage options are indispensable for the energy transition

The foundations of the wind turbine towers in Gaildorf are water reservoirs with a storage capacity of 70 megawatt hours (MWh). A penstock connects them with a hydroelectric power station and its lower reservoir located 200 meters deeper into the valley. The water battery, which was also referred to as natural power storage in the Gaildorf pilot project, can store surplus power from the grid and release it when necessary. It acts as a short-term storage facility and helps to maintain grid stability while guaranteeing a continuous, uninterrupted supply of power. The pumped-storage plant is able to switch between production and storage within 30 seconds.
