Concept of cross-seasonal energy storage water

What is seasonal thermal energy storage?

Generally speaking, seasonal thermal energy storage can be used by storing summer heat for winter use or storing winter cold for summer use, i.e., summer heat for winter use and winter cold for summer use. Common seasonal heat storage includes seasonal sensible heat storage, seasonal latent heat storage, and seasonal thermochemical heat storage.

What are construction concepts for large or seasonal thermal energy storage systems?

Fig. 1. Construction concepts for large or seasonal thermal energy storage systems and their advantages and disadvantages . 2.1.1. Tank thermal energy storage (TTES) A tank thermal energy storage system generally consists of reinforced concrete or stainless-steel tanks as storage containers, with water serving as the heat storage medium.

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.

What is seasonal thermal storage based on supercooled PCM?

The future research direction of seasonal thermal storage based on supercooled PCM is proposed. Seasonal thermal energy storage (STES) is a highly effective energy-use system that uses thermal storage media to store and utilize thermal energy over cycles, which is crucial for accomplishing low and zero carbon emissions.

What is triggered crystallization in seasonal thermal energy storage?

In seasonal thermal energy storage, on-demand triggered crystallization is more common. Currently, the common ways to trigger crystallization in seasonal heat storage include adding seeds, mechanical vibration, applying electric fields, and cooling down crystallization.

How to use PCMs as seasonal thermal energy storage media?

There are two ways to use PCMs as seasonal thermal energy storage media, one is the direct-type, which directly uses the performance of PCMs, and the other we can call the supercooling-type, that is, using its supercooling capacity for thermal storage, the latter way is also the main way to use PCMs for seasonal thermal energy storage.
