Topic & aim

The aim of the project is to consistently exploit the advantages of small biomass-fueled CHP-plants: constant availability, storage capacity and the capability to partly compensate for high volatilities of wind and solar power in electricity and heat generation. Furthermore, application possibilities for such plants will be substantially further developed while thermal energy grids will be the basis to investigate load management and generation schedules for electric power grids.
