Phase Change Materials (PCMs) are one of the most effective and efficient mediums for thermal energy storage (TES), offering a cost-effective, stable, and environmentally friendly solution. Thermal Energy Storage (TES) technology eliminates the dependency on instantaneous electricity for heating or cooling applications. TES is one of the clean technologies which supports and extends the use of other clean technologies such as solar, wind, Distributed Renewable Energy (DRE), electric vehicles etc. This means more control over the end use without relying on electric power for the purpose of heating and cooling from the grid or electric batteries or diesel generators.

Phase Change Materials (PCMs) are one of the most effective mediums of thermal energy storage as they are highly cost effective, stable and environment friendly. PCMs have very wide scope of applications whether it is building construction, cold-chain transportation/storage, solar energy storage, temperature controlled packaging for food, pharmaceuticals etc.

FAQs

How can Phase Change Materials (PCMs) help reduce energy costs for my business?

PCMs allow thermal energy to be stored during off-peak hours—when electricity is cheaper—and used during peak demand, when energy costs are higher. This load shifting capability significantly reduces electricity bills in cooling and heating systems. Additionally, PCMs can replace fossil fuel-based systems like diesel generators in backup applications, leading to lower operating costs and reduced carbon emissions.

How do Phase Change Materials improve temperature-controlled packaging for sensitive products?

PCMs can be engineered to store and release thermal energy at precise temperatures (e.g., +3°C or +5°C), making them ideal for maintaining strict temperature compliance in pharmaceutical and food logistics. Unlike conventional ice packs, which risk freezing the product and require deep freezing at -20°C, PCMs designed precisely for +3 deg celsius and +5 deg celsius ( savE®OM03 and savE®OM05 respectively) provide controlled cooling within the required range (2–8°C) and can be conditioned at higher temperatures (e.g., -10°C), resulting in energy efficiency and improved payload protection.

What are the commercial applications of Phase Change Materials in cold storage and logistics?

PCMs are used to enhance the performance of solar-powered cold rooms, enabling 24/7 cooling even without grid power. In cold chain logistics, reefer trucks and micro cold rooms are increasingly integrating PCM systems to reduce reliance on diesel or fully electrify the cooling system. Compared to Li-ion batteries, TES systems offer at least 5x the lifecycle (over 5,000 cycles) and are 3x more cost-effective (as low as ₹4,000 per kWh of thermal storage). This makes PCMs a commercially viable and sustainable alternative in both Indian and international markets.

Can Phase Change Materials be used to improve energy efficiency in buildings?

Absolutely. PCMs are highly effective in reducing the heating and cooling loads in buildings. In centralized HVAC systems, PCMs offer thermal demand flexibility, which helps downsize chiller capacity and reduces energy costs. For passive cooling strategies, PCMs with melting points around +22°C(savE® HS22) are integrated into building interiors, allowing them to absorb heat during the day and release it at night when ambient temperatures drop. This passive thermal regulation is especially effective in climates with high day-night temperature variations.

Are Phase Change Materials environmentally friendly and safe to use?

Yes, PCMs are non-toxic, non-flammable, and chemically stable under normal operating conditions. Many PCMs are derived from bio-based or salt hydrate materials, making them a sustainable alternative to traditional cooling or heating systems. Their long operational life (often over 20 years) and compatibility with renewable energy sources further contribute to reducing carbon footprints and promoting eco-friendly energy solutions.
