The goal of the project is the realization of a prototype/demonstration model for a total energy system for specific areas, consisting of a storage unit for thermic energy that is connected to a hybrid smart micro grid. The aim is to provide a 100% durable energy supply for specific areas (residential area of 200-400 houses).

There is a mismatch between the supply of durable energy (sun and wind) and the energy need. “Storage is the missing link”. Ecovat provides a solution in storage, and by way of a hybrid micro grid the storage is coupled as well as to the supply, as to the demand side of energy of a residential area.

The design has been tested on feasibility. Prerequisite is, that it is possible to completely close the Ecovat thermically. It has to be placed underground by special building techniques (provided by Soilmix), which also has to be adapted and tested (Wedam/Hoffmann group). Also the storage of warmth in an Ecovat should be charged and uncharged in a smart way, in combination with the supply of electrical energy, through a hybrid smart micro grid (University of Twente).
