SWS-HEATING is developing an innovative seasonal thermal energy storage (STES) unit with a novel storage material and creative configuration based on a sorbent material embedded in a compact multi-modular sorption STES unit.
It will allow to store and shift the harvested solar energy available abundantly during the summer to less sunny and colder winter periods, thus covering a large part of domestic heating and hot water demand all year round.
In more detail, the project plans to develop a compact and high-performing STES system at low cost. It will then commission a building prototype including the SWS-heating system which will be tested and validated in Germany and Sweden. The long-term goal is to contribute to the development of solar-active houses throughout the EU.
The project's ambitious goal is to meet over 60% of energy demand of buildings located in Northern and Central Europe with solar energy. In Southern Europe, which is generally sunnier, SWS-HEATING hopes to cover 80% of buildings' energy demand by producing energy from the sun.
