EOS - Increasing the energy and cost efficiency by optimizing structural tubes

Heat exchangers are technical components for energy processes that are used in large numbers in a wide variety of applications. So-called waste gas heat exchangers are specifically used to increase the efficiency of plants in which heat is recovered from waste gases. The EOS project involves the development of a method for optimizing the energy and cost efficiency of waste gas heat exchangers. The aim is to maximize heat transfer while reducing production costs at the same time.

smartHeat - Use of excess electricity in heat storage systems

The share of renewable energies in electricity generation has risen sharply in Germany in recent years. However, the German power grid has not yet been upgraded for the changeover to a renewable energy supply. To avoid grid overload, photovoltaic and wind power plants are currently regulated incrementally using ripple control receivers, or are being disconnected from the grid altogether.
