• By 2028, 2 to 8 deg C alone is expected to reach USD 1253 Mn, with -20 to -35 deg C at USD 444 Mn.

Market Dynamics

Phase change materials (PCMs) are substances that can store and release large amounts of thermal energy as they change from solid to liquid and vice versa. They have become increasingly popular in recent years due to their ability to regulate temperature and reduce energy consumption in various applications. In the UK, there is a growing demand for PCMs across different temperature ranges, making it a key market for this technology. One of the key temperature ranges for PCMs in the UK market is the low temperature range, which typically includes temperatures from -40°C to 10°C. PCMs in this range are commonly used in cold chain applications, such as refrigerated transportation, cold storage and packaging. They help in maintaining a stable temperature within the required range, preserving the quality and safety of perishable products during transport and storage. For instance, in the food and pharmaceutical industries, PCMs are used to regulate the temperature of vaccines, blood products and food items, ensuring they remain fresh and uncontaminated. In addition to the low temperature range, there is also a growing demand for PCMs in the medium temperature range (10°C to 40°C) in the UK market.

These PCMs are typically used in heating, ventilation and air conditioning (HVAC) systems to maintain a comfortable indoor temperature. The use of PCMs in HVAC systems helps to reduce energy consumption by storing thermal energy during off-peak hours and releasing it when needed, thus reducing the reliance on air conditioning and heating units. This is especially important in a country like the UK where energy costs are high and environmental concerns are on the rise. Another segment of the UK PCM market is the high temperature range (above 40°C), which is used for industrial and manufacturing processes. These PCMs are used to regulate the temperature of machinery and equipment, preventing overheating and costly breakdowns. Additionally, PCMs in this range can also be used for thermal energy storage in district heating systems, where surplus heat is stored and used during peak demand periods. In conclusion, the demand for PCMs in the UK market is driven by the need for energy-efficient and sustainable solutions across various temperature ranges. With increasing awareness and government initiatives towards reducing energy consumption and emissions, the demand for PCMs is expected to further increase in the coming years.

As a result, manufacturers are constantly developing new and improved PCMs to cater to the specific temperature range needs of different industries and applications in the UK.
