Thermal Energy Storage Market Trends

Decentralization of the renewable energy sector to boost the market growth

The deployment of decentralized renewable thermal energy storage is powering a disrupting transformation of the energy sector. The speedy growth of decentralized renewable energy technologies is likely to change the structure of the energy sector towards a multi-operator set-up in which large utilities interact with captive consumers and mini-utilities. Renewable energy distributed through the grid and mini-grids and off-grid installations has provided power to 30% of the people who have gained access to electricity since 2000. To achieve a 100% electrification rate by 2030, decentralized renewable thermal energy storage share will need to increase significantly. For over 70% of those who gain access in rural areas, decentralized systems based on renewable energy will be the most cost-effective solution.

Further, governments, associations, and universities across the globe are taking several steps to invest actively in R&D to come up with creative storage mediums which have a low or zero effect on the environment. The growing government initiatives coupled with technological advancement initiatives adopted by various vendors are anticipated to boost the thermal energy storage market CAGR over the forecast period.

Additionally, renewable power generation and thermal energy storage have emerged as major alternatives to fossil fuels, thus reducing the dependency on them. This, in turn, has resulted in a viable solution for countries worldwide to opt for them to meet their carbon reduction targets and switch towards cleaner energy technologies. The rise in the deployment of renewable energy in the last decade has been noticed on account of these methods.

However, renewable energy sources, including solar and wind, have intermittent supplies. To counter the intermittency nature of large-scale renewable deployment, thermal energy storage systems provide a viable solution as they can be integrated with CSP projects to boost the thermal energy storage market revenue positively.

Thermal Energy Storage Market Segment Insights:

Thermal Energy Storage Technology Insights

The Thermal Energy Storage Market segmentation, based on technology, includes sensible heat storage, latent heat storage, and thermochemical storage. The sensible heat storage segment held the majority share in 2021 of the Thermal Energy Storage Market revenue. This can be attributed to the rising demand for solar thermal energy storage and their applicability across large-scale HVAC systems. However, thermochemical storage is the fastest-growing category over the forecast period. In this storage, the heat stored by various mediums is released when a reverse reaction occurs between them. This type of heat storage is preferable for the long-term repository as losses do not occur over time but only during the charging and discharging phases.

Thermal Energy Storage Material Insights

The Thermal Energy Storage Market segmentation, based on storage material, includes water, molten salt, phase change material, and others. The molten salt segment dominated the market in 2021 and is projected to be the faster-growing segment during the forecast period, 2022-2030. This is due to its high technological efficiency and usage in various solar energy projects. Molten salt is utilized to store the heat collected using solar troughs and solar towers. However, phase change material is the fastest-growing category due to the global energy-saving and sustainable development trend.

November 2022: Hyme Energy ApS announced that the company is partnering with Bornholms Energi & Forsyning (BEOF) to construct its first molten salt thermal energy storage storehouse demonstrator on the Danish island of Bornholm. The storage structure is designed for completion in 2024 and will have an accommodation of 1 MW/20 MWh. It will deliver heat, power, and ancillary services to the local network.

Thermal Energy Storage End User Insights

The Thermal Energy Storage Market data has been bifurcated by end users into commercial & industrial, utilities, and residential. The commercial and industrial segment dominated the market in 2021 and is projected to be the faster-growing segment during the forecast period, 2022-2030. Rising infrastructure development and establishment spending will propel the demand for HVAC systems. Hence, the growing adoption of these systems across several industries using large quantities of hot water for economic purposes positively impacts market growth. However, residential is the fastest-growing category over the forecast period. Thermal energy storage plants are used to generate electrical energy to suffice the energy demand of the residential sectors.
