Kremsmüller Heat storage tanks
Renewable energies such as wind and solar power are central to the energy transition. However, they are not always available when energy is needed. Heat storage systems provide the necessary flexibility here: they convert surplus electricity into heat and make it available when needed. In this way, they help energy suppliers to combine security of supply with climate protection.
One of the key challenges of the energy transition is the efficient storage of electrical and thermal energy. Kremsmüller’s heat storage solutions make an important contribution to this: they enable the use of waste heat from power generation and industrial processes, as well as the storage of surplus energy from renewable sources.
Heat storage systems enable renewable energies to be integrated efficiently. Electricity and heat are decoupled, enabling economical and flexible energy management in the grid.
The energy transition is already in full swing and will gain even more momentum in the coming years. The shift to more and more renewable energies and the necessary increase in the efficiency of existing power plants require targeted optimizations to ensure a secure energy supply at all times. Together, we are shaping the energy transition locally—with experience, innovative strength, and tailor-made solutions for municipal and industrial energy projects.
Ingolstadt Municipal Utilities uses waste heat from surrounding industrial plants, including Audi, to supply its district heating network. Two 25-meter-high heat storage tanks store up to 170 megawatt hours of energy in the form of 130°C hot water and release it as needed.
The project – the largest of its kind in Bavaria – was implemented by Kremsmüller Anlagenbau in collaboration with Max Straube GmbH. In addition to the storage facility construction, it also includes the hydraulic integration into the network and a modern pressure maintenance system.
“New landmark for Ingolstadt” is a bit of an exaggeration for these striking towers, especially with Audi as their neighbor. But the project does have a certain appeal—particularly from a technical standpoint, with its guarantee of CO2-neutral heating.
As part of the SolarHeatGrid climate protection model project, Stadtwerke Ludwigsburg-Kornwestheim implemented Germany’s largest solar thermal plant in 2017. A key element of this project was a high-performance heat storage tank, which was implemented by Kremsmüller in collaboration with Max Straube in 2019/2020.
The pressure storage tank has a capacity of 2,000 m³, operates at 5 bar overpressure and temperatures of up to 110 °C. With a height of 20 meters and a diameter of 14 meters, it weighs up to 3,000 tons when in operation. Twenty-four bored piles were driven 13 meters deep for the foundation – a technical masterpiece for a stable, inner-city energy supply.
