Water Battery Is a Natural Power Storage Facility, says Wind AG

By Paul Dvorak | August 9, 2017

Max Bögl Wind AG demonstrates its new power plant and storage concept at the ESNA in California

Max Bögl Wind AG will present its products with a globally unique natural storage technology at this year’s Energy Storage North America (ESNA) fair in San Diego. From August 8 to 10, the company will present its water battery at booth 629.

Water Battery: How It Works

Of course, the device described here is not a battery in the chemical sense of the term, but rather a way to store energy,        and in this case, kinetic energy of the stored water.

 

With the water battery, Max Bögl Wind AG has developed a completely new large-scale storage facility, which sets new standards in a technologically innovative way. For the first time, the production of power from renewable energies, such as from a wind or solar farm or from biomass, will be combined with a modern pumped-storage power plant. The water battery can store surplus power from the grid and the energy can be reused as required. It acts as a short-term storage facility and contributes to maintaining the stability of the grid, as well as guaranteeing continuous, uninterrupted supply. The pumped-storage power plant is available in three performance classes (16, 24 or 32 MW) and can switch between production and storage within 30 seconds.

Wind turbine as a water battery storage resevoir

The foundations of the wind turbines serve as storage reservoirs.

The first project is currently being developed in Germany near Stuttgart. It consists of a wind farm with four wind turbines and a pumped-storage 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 MWh. A penstock connects them with a hydroelectric power station and the corresponding lower reservoir 200 meters below in the valley.

“The water battery is a natural storage facility which stands out for its durability and high degree of flexibility,” says Jürgen Joos, CFO at Max Bögl Wind AG.

The first water battery: made in Germany.
