Salt Hydrate Market

Salt Hydrate Market Growth Outlook (2024 to 2034)

The global salt hydrate market size is expected to be valued at US$ 95.8 million in 2024 and forecasted to expand at a CAGR of 10.4% to climb to US$ 255.4 million by the end of 2034.

Salt hydrates are inorganic salts that contain water molecules in their structure. They have different physical properties from anhydrous salts such as color and density. Salt hydrates boast a high thermal energy storage density. Salt hydrates are an inorganic type of phase change material (PCM) with a melting point of 20 °C to 25 °C. This makes them suitable for construction projects.

Ability of salt hydrates to absorb excess moisture prevents mold formation in medicines, making them useful in the pharmaceutical sector. Glauber salt is an example of hydrated salt used in the textile industry for dyeing wool, nylon, and silk.

Copper sulfate pentahydrate is another example of hydrated salt, which is used in agriculture as a fungicide, algaecide, herbicide, and root killer. Hydrated salt is also employed in the healthcare and beauty sectors. It is generally found in bath products as it has muscle-relaxing properties. Due to extraordinary properties such as gaining and releasing thermal energy, it is considered an ideal candidate for photovoltaic cells in solar cells for ideal thermal energy storage.

• From 2019 to 2023, the global salt hydrate market size expanded at a CAGR of 8.1%, according to Fact.MR, a market research and competitive intelligence provider.

What are the Key Salt Hydrate Market Trends to Focus On?

“Rising Number of Warehouses and Cold Supply Chain Facilities”

Cold storage warehousing is essential for the food industry, as it helps food products move efficiently through the supply chain by offering food safety assurance. PCMs are used in walls of cold stores, which limits the rising temperature inside cold storage facilities during loss of electricity by absorbing the thermal load that enters the cold storage space. Rising use of cold storage warehouses is contributing to the salt hydrate market growth.

• For instance, according to the International Institute of Refrigeration, the total capacity of refrigerated warehouses around the world was 719 million cubic meters in 2020, which was 16.7% greater than the capacity in 2018.

“Extensive Utilization of Salt Hydrates in Construction Sector”

Salt hydrates are integrated into the structure of buildings to reduce the ongoing cost of building operations such as daily heating and cooling. Compared to all other PCM options, salt hydrates have superior thermal storage densities and cost-effectiveness, rendering them highly attractive for practical engineering applications.

• According to the research paper published by the International Journal of Civil Engineering and Technology (IJCIET), the use of PCM can save energy up to 40%, which makes it an important material for green building construction. Green building construction promotes the usage of salt hydrates in concrete.
• For instance, according to a World Bank report, the construction sector was valued at US$ 27.76 trillion in 2022, and it is projected to grow at a significant pace through 2034. The construction sector is forecasted to drive the demand for salt hydrates.

What are the Hindrances to Market Growth?

“Corrosiveness of Inorganic Salt Hydrates and Technological Limitations in Processing”

Several studies have discovered the disadvantages of inorganic salt hydrates such as corrosiveness, which may release harmful substances into the environment. When salt hydrates are used in photovoltaic (PV) cells, the risk of supercooling and phase separation can reduce the PV cell efficiency. These technological limitations while processing methods hinder growth.

Emergence of substitutes could additionally limit market expansion. Economic variables such as volatile demand or elevated production expenses may further challenge market viability.
