6 FAQs about [Concentrated solar underground thermal storage]

What is thermal energy storage?

Thermal energy storage provides a workable solution to the reduced or curtailed production when sun sets or is blocked by clouds (as in PV systems). The solar energy can be stored for hours or even days and the heat exchanged before being used to generate electricity .

Can thermal energy storage reduce solar energy production?

One challenge facing the widespread use of solar energy is reduced or curtailed energy production when the sun sets or is blocked by clouds. Thermal energy storage provides a workable solution to this challenge.

What is concentrating solar thermal power (CSP)?

1. Introduction Concentrating solar thermal power, more commonly referred to as CSP, is unique among renewable energy generators because even though it is variable, like solar photovoltaics and wind, it can easily be coupled with thermal energy storage (TES) as well as conventional fuels, making it highly dispatchable.

Why should thermal energy storage technologies be developed?

CONCLUSIONS Thermal energy storage technologies need to be developed and become an integral component in the future energy system infrastructure to meet variations in both the availability and demand of energy.

Does solar energy have a 'long term' storage requirement?

Solar energy has a one-day period, meaning that the ‘long term’ storage requirements is based on hours. In that context, thermal energy storage technology has become an essential part of CSP systems, as it can be seen in Fig. 13, and has been highlighted over this review.

What is underground thermal energy storage (Utes)?

Underground thermal energy storage (UTES) provides large scale (potentially >10 GWh) storage capacity per site that is difficult to achieve with other heat storage technologies, and benefits from a typically lower range of storage costs (Persson et al.,2014).
