PtH4GR²ID - Power to Heat for the Greater Region's Renewables Integration and Development

Project Description

In the context of Power to Heat, PtH4GR²ID investigates the potentials of electricity-guided heat pumps in combination with storage technologies from an economic, technical and social point of view. The basis is the development of a sustainable control concept for heat pump and storage planning. After simulation calculations have been carried out, the findings are evaluated on the basis of pilot installations in the Greater Region. In addition to technical feasibility and cost-effectiveness, social acceptance plays a decisive role. The project has a total budget of around 2.6 million euros and is 60 percent funded by the European Regional Development Fund (ERDF). The Unit of Real Studies contributes to the project by calculating the life cycle costs for the buildings to be modernised.
