References on seasonal energy storage

Why is seasonal energy storage important?

Energy storage at all timescales, including the seasonal scale, plays a pivotal role in enabling increased penetration levels of wind and solar photovoltaic energy sources in power systems.

What is seasonal thermal energy storage (STES)?

The applications of seasonal thermal energy storage (STES) facilitate the replacement of fossil fuel-based heat supply by alternative heat sources, such as solar thermal energy, geothermal energy, and waste heat generated from industries.

Does seasonal thermal energy storage provide economic competitiveness against existing heating options?

Revelation of economic competitiveness of STES against existing heating options. Seasonal thermal energy storage (STES) holds great promise for storing summer heat for winter use. It allows renewable resources to meet the seasonal heat demand without resorting to fossil-based back up. This paper presents a techno-economic literature review of STES.

Can solar energy be used as a seasonal energy storage facility?

In combination with seasonal energy storage, solar energy can make a major contribution to heating of buildings. The incoherency of the solar radiation peak season and space heating demand creates the interest in applying the ground as a seasonal storage medium of solar energy. A seasonal storage facility can be designed in many different ways.

How can a seasonal storage facility be designed?

A seasonal storage facility can be designed in many different ways. Heat can be stored in the ground (clay, sand), in unfractured rocks, and in water [7, 40–42]. Four fundamental options for long-term solar thermal energy storage are presented in a schematic way in Figure 14 and they are mentioned below: Figure 14.

Can grid-integrated energy storage reshape seasonal fluctuations?

Grid-integrated seasonal energy storage can reshape seasonal fluctuations of variable and uncertain power generation by reducing energy curtailment, replacing peak generation capacity, and providing transmission benefits.
