Prospects for the application of thermal power storage in sweden

Can thermal energy storage improve energy management?

Thermal energy storage (TES) technologies have significant potential to improve energy management across a wide variety of sectors.

What is a thermal energy storage system (SA)?

In these cases, SAs are the only commercial solution for thermal energy storage in DSG . In this application, the steam is stored at high pressure in saturated liquid water as active direct storage, i.e. the steam is generated in the solar receiver and stored directly in the accumulator, as shown in Fig. 4.9.

What is the future of the Swedish energy system?

Table 1. Summary of literature review. In case of the Swedish energy system, there are uncertainties surrounding the future of nuclear power plants, the anticipated increase in wind and solar PV installations, electrification trends, and the role of hydrogen in the steel industry [34, 35].

What is a thermal energy storage system (CSP)?

A storage solution applicable for CSP technology is the introduction of a thermal energy storage system to store heat provided by the heat transfer fluid (HTF) in order to buffer through weather events and provide thermal energy for electricity generation when solar energy is otherwise absent (e.g. at night).

What are thermal energy storage technologies?

Thermal energy storage technologies occupy a unique position in the energy sector. On the one hand, the basic principles of storing heat have been understood for well over a century and applied in domestic and industrial settings. This includes concepts as fundamental as hot water heaters or regenerator heat storages in steelmaking processes.

How much energy does a thermal storage barge use?

To transport the thermal storage barges, the ship needs a calculated amount of diesel of 6700 GJ/year and a comparable amount is calculated for the primary energy needs for electricity (650,000 kWh/yr) to run the pumps for the heat transfer fluids. The primary energy ratio of energy consumed over thermal energy delivered is 7%.
