Seasonal thermal energy storage (STES), also known as inter-seasonal thermal energy storage, is the storage of heat or cold for periods of up to several months. The thermal energy can be collected whenever it is available and be used whenever needed, such as in the opposing season. For example, heat from solar collectors or waste heat from air conditioning equipment can be gathered in hot months for space heating use when needed, including during winter months.
Inter-seasonal compressed air energy storage using saline
to ensure energy security. More specifically, inter-seasonal storage will likely be a combination of PHS, CAES, and possibly geological hydrogen storage8. CAES is currently the only other

6 FAQs about [Danish inter-seasonal energy storage kroner]
How can we achieve 100% decarbonisation of the Danish district heating system?
Reaching the stated target of 100% decarbonisation of the Danish district heating systems by 2030 involves ongoing integration of renewable energy resources, for example solar power and wind power, via large heat pumps and geothermal heating; large-scale and seasonal heat storage, and increased harvest of industrial waste heat.
How did Danish heat infrastructure planning work?
The heat infrastructure planning strategically integrated CHPs further into the Danish energy system. The heat supply areas for district heating and the Danish North Sea natural gas were also mapped via a nation-wide planning process referred to as ‘zoning’ [8, 9, 57, 59, 60].
Why is the Dronninglund seasonal storage system better than the Marstal system?
During the webinar, Nielsen gave three reasons why the efficiency of the Dronninglund seasonal storage is significantly better than that of the Marstal system: The Dronninglund seasonal storage is connected to the district heating grid via a heat pump. This makes for lower storage temperatures throughout the year, which reduces heat losses.
Does Danish energy policy change with low-carbon energy transitions?
Shifts in Danish energy policy related to the ongoing low-carbon energy transitions in Denmark are examined in Ref. . Focussing on energy flexibility, it explores the policy changes that affected the previous, strong support for Danish district heating.
What are the unique features of the Danish district heating sector?
Other unique features of the Danish district heating sector include large-scale collective heat planning, the mandatory connection, the non-profit principle, the same approximate price for customers irrespective of heat density, and the relatively high average price of district heating.
When did Denmark start implementing a low-carbon energy transition strategy?
The Danish government published the Energy 2000 Action Plan in 1990, the first low-carbon energy transition strategy in the world. This energy plan prioritized the integration of renewable energy resources into the Danish energy system and planned for phasing coal out of the system.
