Sweden s thermal power storage project is the world s first

Why is thermal energy storage important?

As thermal energy accounts for more than half of the global final energy demands, thermal energy storage (TES) is unequivocally a key element in today’s energy systems to fulfill climate targets. Starting from the age-old TES practices in water and ice, TES has progressed today into many energy systems.

When did geothermal energy start in Sweden?

Geothermal energy utilization started in Sweden in the 1970’s and 1980’s, triggered by the oil crises, and the following nationwide efforts towards an oil-independent energy system. Heat pump technology was promoted, favored by the national power production strategy based on nuclear and hydropower.

Which Swedish energy storages are being built in 2024?

13 February 2024 SWEDEN – The energy storages are being built in Falköping (16 MW), Karlskrona (16 MW), Katrineholm (20 MW), Mjölby (8 MW), Sandviken (20 MW), Vaggeryd (11 MW), Värnamo (20 MW) and Västerås (11 MW). A storage with a power of 20 MW correlates to what a Swedish town with 40,000 inhabitants on average consumes during peak hours.

What is the Arlanda Airport aquifer – thermal energy storage system?

The Arlanda Airport Aquifer – Thermal Energy Storage System is an 8,000kW energy storage project located in Arlanda, Stockholm, Sweden. The thermal energy storage project uses others as its storage technology. The project was commissioned in 2009. Description The Arlanda Airport Aquifer – Thermal Energy Storage System was developed by LFV Group.

Could a high-temperature packed bed thermal energy storage system be used?

Researchers from Sweden's KTH Royal Institute of Technology have designed a high-temperature packed bed thermal energy storage (TES) system that could be used for the storage of electricity generated by large-scale renewables.

Does Sweden use geothermal energy?

The extensive use of ground source heat pumps (GSHP) nationwide has made Sweden the European leader in geothermal energy utilization, in terms of installed units and capacity, as well as extracted thermal energy (Antics et al. 2013). Approximately one fifth of all single-family houses in Sweden are heated by a GSHP.
