Success factors for small heat grids with seasonal geothermal heat storage
The key factors for the development of a sustainable economy are: a reasonable reduction of the energy services which society can bear, the increase of energy efficiency for the entire energy conversion chain and the use of renewable energies for the remaining energy demand.
GEOSOL deals with the energy services space heating and water heating. They examine structural, technical, economical and social factors of success for the operation of regional solar powered small heat grids with seasonal geothermal heat storage.
The examination of a model system which consists of heat sources (solar thermal collectors), heat sinks (buildings and water heating), heat storages (shallow geothermics) a heat grid and heat pumps is the methodical starting point. The model is displayed in a dynamic computer simulation with a focus on the seasonal geothermal heat storage.
The project is realized in cooperation with the technical high school Wiener Neustadt. The pupils analyse specific case studies in the wider area of Wiener Neustadt. Furthermore they plan to build a field laboratory in order to investigate ground collectors. Additionally they develop a project website, create an information folder and present the project at events.
GEOSOL's results show determining factors for an economically and ecologically reasonable operation of specific systems. In addition the results demonstrate the practicability of these systems based on case studies. In the conclusions the future importance and implementation potentials in Austria are pointed out.
