Emerging Trends in Inorganic Phase Change Material Market

By 2027, Lucintel anticipates the preference for phase change materials within the building, cold chain logistics, electronics, thermal storage, and building specification markets will replace pilot project preferences. Lucintel anticipates purchasing decisions will be based on performance, fire safety, and lifecycle economics. It is expected developers will buy phase change materials for reliable thermal management solutions as an alternative to new (novel) materials.

• Sustainability: In 2025, there was increased interest by building owners in the sustainability of thermal storage materials, including embodied carbon, toxicity and service life. Due to the demand for building carbon impact reporting, it is expected repeatable thermal energy storage will become an important factor in procurement choices.
• Digital Manufacturing: Within the years 2025 to 2027, automation of the control of formulations of salts and hydrates, as well as automated mixing has become the norm and so has formulation software. Digital twins are modeling thermal energy storage windows, which is expected to reduce the qualification time and allow for larger orders.
• Functional Products: In March of 2025, there was increased specification interest for PCM packs covering very narrow temperature bands, including logistics for the health care sector with a band of 2 to 8 degrees C; the market is evolving toward composite materials that integrate structural stability, corrosion resistance, and latent heat of fusion. Functional differentiation will maintain the profitability of the product beyond the margins for commodity products.
• Regional Supply Chain Diversification: Responses to unpredictability in freight costs in 2025 prompted a preference for a second source for salt, encapsulant, and container production. Regional production is anticipated to shorten lead times and reduce inventory within the next 3 to 5 years. However, qualification remains slow.
• Automation: PCM systems integrated into thermal energy storage units in 2025 were able to charge or discharge during peak demand pricing periods thanks to building management controls and automation. With automation, systems are able to use capacity more efficiently by up to 15% when compared to a fixed controlled system. Increased flexibility makes inorganic phase change materials much more economical to install in high energy use buildings.

The next phase of the market will compensate suppliers based on verified thermal outputs rather than material sold. Inorganic PCM has some advantages over organic PCM such as fire resistance and temperature stability. Adoption will continue to be specific to each application, but the construction of cold chains and the flexibility the systems can provide to the electrical grid will provide a consistent demand for the technology. Scalable solutions will be based on engineering while short term demonstration platforms will fail.

Recent Developments in the Inorganic Phase Change Material Market

The market for inorganic phase change materials is moving from lab phase demonstrations to thermal management, resilient cold chains and efficient build solutions. Activities are expected to increase from 2025 to 2027 as manufacturers improve salt hydrate stability, system integration and fire performance. Lucintel expects this market to grow in parallel with investments in energy storage, data centres and low carbon construction.

• Funding for Thermal Storage Projects: Long duration thermal storage projects are attracting funding under public programs. An example is a $75 million funding round offered by the US Department of Energy in January 2025, which supports a reduction in the risk associated with technology. This will help drive the adoption of inorganic phase change materials by customers and reduce the risks associated with the first installations.
• Partnerships for Data Center Cooling: Inorganic phase change materials are being tested by cooling system providers and data center operators to address peak cooling demands. Demand for thermal buffers will increase from the addition of 2GW of new data centers by Microsoft in their fiscal year 2025 (July 2025).
• Building Code Push: Implementation of the revised Energy Performance of Buildings Directive by EU Member States from 2025 will put pressure on builders to use passive thermal regulation systems. While builders wait, manufacturers must validate the performance of the materials through durable and cycle compliant systems.
• Formulation of Salt Hydrates: Nucleated and encapsulated formulations reduce supercooling and phase separation. Enhanced formulations saved by numerous cycles exceeding 10,000 for HVAC applications and industrial heat recovery were introduced in 2025.
• Investment in Cold-chain Technology Increases: DHL plans to expand its healthcare logistics network in 2025, while pharmaceutical logistics continues its investment in reusable temperature-control packaging. In the meantime, single-use packaging and shipping can be reduced by the use of Inorganic phase change materials that provide stable temperature bands.

The phase change material market will continue its rapid growth over the next five years, but will still be highly fragmented. Suppliers that will gain the most business over this period will sell more integrated systems rather than individual elements. During this period, performance verification, long cycle life, fire safety, and supply assurance will be of greater concern than the nominal magnitude of the latent heat of the phase change material. Growth will be uneven and concentrated in the data center industry, logistics, and in buildings that face stringent energy performance building standards.

Strategic Growth Opportunities in the Inorganic Phase Change Material Market

Expanding data center demand, rules to improve building efficiency, and the push toward electrification are all expected to result in greater demand for solutions in the inorganic phase change material market from 2024 to 2026. Improved economics of the projects is due to reduced cost of storage. Lucintel believes suppliers will shift over the next few years from focusing on commodity heat storage to providing engineered systems, regional manufacturing, and customized products at better margins.

• Building-integrated Thermal Storage: Suppliers in the inorganic phase change material market can produce fire safe storage that integrates into walls, ceilings, and HVAC units. The new version of the EU's Energy Performance of Buildings Directive was published in May 2024. This provides an opportunity as developers look for ways to reduce peak demand without growing mechanical systems..
• Data-center Cooling: Encapsulated salt hydrate systems can be used to store short duration peak loads and reduce oversizing of chillers. Per the IEA's April 2025 report, global data center electricity demand is projected to reach 945 TWh by 2030. The increasing densification of data center infrastructure will create a market for service providers of thermal buffers for the next 3 to 5 years.
• Cold-chain Logistics: Engineered inorganic PCM can be used to maintain a constant temperature during transportation of pharmaceuticals. The World Health Organization reported in February 2025 that over 100 million infants still receive immunizations without a break. The market for thermal buffers will be created by ongoing contracts for thermal shippers validated, replaced, and monitored for their service.
• High-temperature Phase Change Materials: Materials with this capacity can capture waste heat from manufacturing processes of cement, metal, and chemical industries. The U.S. DOE has announced $6 billion grants for industrial decarbonization technologies in 2024. With a carbon-cost pressure, retrofits will become economically attractive when the stored heat displaces fossil fuel firing.
• Combining Food Heat Pumps with Phase Change Materials: Shifting peak demand through off-peak operation of heat pumps becomes possible by incorporating phase change materials. A €1.8 billion renewable energy subsidy by the European Commission for the German industry was approved in February 2025. For both utilities and commercial clients, thermal energy storage will become more of a cost-effective solution than fully electrical batteries.

The focus should be placed on the cycle life, corrosion, fire safety, and end of life services, rather than selling the capacity for latent heat storage. Manufacturing partnerships should help shorten the time to market and reduce the risk of design, while local manufacturing should further reduce the cost and risk. The companies that will dominate this space will make sales of the materials with design support, monitoring, replacements, and recorded carbon Sequestration for customers.

Inorganic Phase Change Material Market Drivers and Challenges

The inorganic phase change material market is sensitive to technology, economic, environmental, and regulatory factors. Growing demand for advanced thermal management solutions exists in the building, electronic, cold chain logistics, and energy storage sectors. Lucintel expects material innovation, increased infrastructure investment, and sustainability goals will become more important. High costs, constrained supply, and performance issues will likely remain key limiting factors.

The following factors will drive the demand for inorganic phase change materials:

• Greater Focus on Efficiency: Increasing energy costs and the push for decarbonization means buildings, warehouses, refrigerated transport systems, and industrial facilities are starting to use thermal storage materials. The International Energy Agency's January 2025 report revealed that buildings still accounted for roughly 30% of global energy demand, thus creating the necessity for passive temperature control. Inorganic phase change materials can help offset both the cooling and heating loads by storing and discharging heat at constant temperatures. Over the next three to five years, more demanding energy performance and the ongoing investment into efficient infrastructure will create further demand for materials with peak load reduction and improved temperature control.
• Increased Demand for Thermal Energy Storage: Growth in solar and wind energy has led to increased demand for thermal energy storage technologies that can compensate for the varying energy supply. According to one expert prediction for June 2025, over 5,000 GW of renewable power capacity will exist by the end of the decade. This greatly elevates the need for flexible energy storage. Inorganic phase change materials (e.g., salt hydrates, metallic compounds) are able to absorb a lot of energy and therefore support the reconstruction of useful process heat in industry. Their role in integrated district heating, concentrated solar power, and other industries will become more important over the next three to five years as governments and utilities look for alternatives.
• Increased Demand for Thermal Energy Storage: Research is investigating phase stability, thermal conductivity, supercooling, corrosion resistance, and improved encapsulation. As of March 2026,advanced thermal storage materials research is focused on innovative materials that will improve heat transfer by approximately 20% in a lab setting. These innovative materials will address some of the traditional drawbacks that include degradation, leakage, and slow charging. Customization of the temperature range will be improved with better digital models and characterization tools over the next three to five years. Improved thermal stability and reliability of inorganic materials will allow for entry into new markets that were previously unexplored.
• Increasing Demand for Cold-Chain and Temperature-Controlled Logistics: Global distribution of healthcare related products, ingredients for food processing and meal delivery, as well as transportation of biological products, require temperature control. As of October 2025, the World Health Organization continued highlighting that many temperature-sensitive drugs have distribution requirements that include a controlled range between 2°C and 8°C. Inorganic phase change materials can provide passive thermal protection in temperature controlled insulated shipping containers. These materials have been found useful for long and risky transportation where power supply is unstable and/or unreliable because of their stability and ability to remain molten for a relatively long time. Over the next three to five years, the logistics for vaccines, biologics, and fresh food will show a positive demand growth.
• Improved Manufacturing Efficiency and Product Innovation: Manufacturing of shape-stabilized, encapsulated, and modular inorganic phase change materials in various configurations is a new focus for material manufacturers. In February 2026, it was expected that industrialized countries would continue to invest over 500 billion USD in automation technology. Easy-to-install thermal management systems with highly configurable materials will offer advantage to manufacturers due to their integration into various systems with advanced formulations requiring low space and less maintenance. Volume productions may also have a positive cost impact due to process improvements. The next three to five years are likely to bring rapid changes in the construction, transport, and other industries due to increased production variety and manufacturing flexibility.

This Market experiences the following challenges:

• High Initial Costs and Commercial Uncertainty: Expenses for inorganic phase change material systems are often higher than the cost of conventional insulation or thermal storage systems. This is due to the specialized containment, heat exchangers, corrosion protection, and the need for custom installation. In August 2025, Engineering, Procurement, and Construction (EPC) firms opted to take on more projects with anticipated on-site system payback of less than five years. It is anticipated that, during the lifecycle of the system, clients will save enough to justify the system cost. However, customers will delay adopting the system because of the uncertainty posed by the combination of fluctuating electricity prices and the anticipated benefits associated with system utilization rates. In the coming three to five years, system manufacturers must provide a total-cost advantage, design modular systems, and develop systems that will lower the client's purchasing cost, as well as develop financing options.
• Corrosion, Safety, and Material Stability Concerns: Salt hydrates and other inorganic compounds suffer from phase separation, supercooling, volume change, corrosion, and even capacity loss after a finite number of cycles. In April 2026, laboratory studies reported an occurring, unexplained variation of more than 10% in performance between various formulations tested under different cycling conditions. These problems provide increased complexity in the design of systems, greater systems cost, the need for additives and increased monitoring, and heightened safety concerns due to the interaction with the contained materials. Under the current conditions, the issues of safety and durability will prevent the adoption of systems utilizing these materials in sensitive applications, such as solar and battery systems, buildings, and high-value logistics where temperature control and long life are of concern.
• Supply-Chain and Regulatory Constraints: Production involves minerals, salts, metals, components for other encapsulations, and specialty additives, which have volatile prices and supplying availability. By September 2025, critical mineral markets were still confronted with risks of both export restrictions and disruptions in shipping and a regional concentration of capacity for processing. More regulatory requirements regarding the handling of chemicals, worker safety, and the transportation of goods adversely impact the bottom line for businesses and the end user. Additionally, the lack of standardization for product testing hinders consumers from making informed choices when comparing different suppliers. Raw material sourcing with greater diversification, supply chain traceability, product testing modifications for sustainability, and design adaptations for market innovations will improve both resilience and customer confidence for the next three to five years.

The inorganic P-CMATM market is expected to show considerable growth from the increased demand for energy efficiency and integration of renewable technologies with the growth of the cold-chain and advanced thermal management systems. Though greater levels of production may increase efficiency and lower costs, customers will still be faced with supercooling, corrosion, uncertainty in supply, complicated regulations, and high capital costs. The first competitive edge will go to market leaders who are able to demonstrate lifecycle cost benefits, safer alternatives, documented performance, and reliable supply. Most likely, the next three to five years will show greater adoption of specialty high-value products in buildings, and related industrial, transportation, electronic, and energy storage systems.
