What is seasonal thermal energy storage (STES)?
Seasonal thermal energy storage (STES) harvests and stores sustainable heat sources, such as solar thermal energy and waste heat, in summer and uses them in winter for heating purposes, facilitating the replacement of fossil fuel-based heat supply and coordinating the seasonal mismatch between heat supply and demand .
How does a thermal energy storage system work?
The excess thermal energy is stored by the thermal energy storage (TES) in summer and released for the thermal load by the GSHP in winter. Most of the thermal load in one year is supplied by the GSHP. The EB can be used to supply heat by absorbing some excess electricity generated by renewable energy.
Can a ground source heat pump provide thermal energy storage?
As the evacuated tube collector area increases, a larger thermal energy storage capacity is required. Above all, the integrated energy system proposed in this paper incorporates the ground source heat pump for seasonal thermal energy storage and addresses the seasonal imbalance between thermal load supply and demand.
How will solar heat storage work?
"The huge storage will be operated as an interseasonal heat storage allowing the solar heating plant to deliver more than 50% of the annual heat production to the network. The rest of the heat will be produced by 3 gas engines, a 10 MW electric boiler, an absorption heat pump and gas boilers." ^ SDH (Solar District Heating) Newsletter (2014).
What are some examples of solar thermal storage?
A number of examples of the use of solar thermal storage from across the world include: Suffolk One a college in East Anglia, England, that uses a thermal collector of pipe buried in the bus turning area to collect solar energy that is then stored in 18 boreholes each 100 metres (330 ft) deep for use in winter heating.
Should district heating be replaced with seasonal thermal energy storage (STES)?
With more renewables in the grid, the benefits of replacing district heating with STES increase. Seasonal thermal energy storage (STES) offers an attractive option for decarbonizing heating in the built environment to promote renewable energy and reduce CO 2 emissions.
