Pit heat storage and large solar collector (SUNSTORE 3, Phase 2)
The aim of the project is to demonstrate a full scale pit heat storage (60.000 m3 ) in combination with a large solar collector field (35.000 m2) and heat pumps (3 MW).
The aim of the project is to demonstrate a full scale pit heat storage (60.000 m3 ) in combination with a large solar collector field (35.000 m2) and heat pumps (3 MW). This energy plant will be able to supply the Danish city Dronninglund with 50% of its heat demand (20.000 MWh). The rest of the heat demand will primarily be produced in a natural gas fired combined heat and power plant. The result is expected to be a well functioning full scale pit heat storage integrated in a total energy concept that can be replicated in a combination with all types of district heating plants, stabilise heat prizes and at the same time give better possibilities for electricity regulation
The objective of the SUNSTORE 3 project has been to optimize, design and implement a full scale demonstration plant with 35,000 m2 solar thermal collectors, 60,000 m3 pit heat stor-age and a heat pump that utilizes the storage as heat source.
The demonstration plant opened in May 2014. The cost is a little lower than budgeted and the production from the plant seems to be as expected.
