Cool Green Energy Factory

Cold energy storage technology


Cool Green Energy Factory is a cold energy storage (CES) system that uses a redesigned multi-use fire water tank to cover the energy needs of industrial cooling processes in factories.

The innovative energy concept is a financially sound, scalable solution for manufacturing companies wishing to make energy-intensive cooling processes economically and ecologically sustainable. The concept emerged from the innovative idea to adapt a fire water tank and to transform it into an energy storage system. To reduce energy costs and CO2 emissions, companies try to use more and more self-generated green energy, for example, in their production plants. (In this case: A 500 kW PV system on a warehouse roof and two nearby wind turbines.) To store the energy surplus generated, a fire water storage tank required by the insurance company for fire protection reasons has been modified so that it can also be used for CES. As a result, cooling for the production process is powered all year with 100% self-generated green energy.


Key features

  • Cooling action required in production runs on 100% green energy.


  • Costlier storage solutions such as batteries are avoided.
  • A payback period of less than five years.
