Overview
Phase Change Materials (PCMs) offer a transformative approach to thermal management in energy storage by strategically controlling temperature profiles through latent heat absorption and release. We introduce a cost-effective, scalable spinel nanoparticle (Cu(Mn0.748Ni0.252)2O4) with exceptional thermal resilience and excellent dispersibility, which was used to create a novel Spinel Oxide-PCM nanocomposite. This nanocomposite demonstrates a 45 % increase in specific heat capacity, promising a new generation of compact, cost-effective, and high-performance thermal energy storage systems.
Key Features
- Nanocomposite PCM with ~ 45 % Cp enhancement
- High temperature stable spinel nanoparticles obtained by cost effective route
- High durable cylindrical PCM capsules with a high-temperature corrosion-resistant coating
- Low production cost
Potential Applications
- Solar Building Cooling & Heating
- Solar Thermal Desalination
- Industrial Process Heat
- Solar Steam Generation for Hydrogen Production
Status
- 1 kWh thermal energy storage (TES) prototype system was successfully integrated with ARCI's existing PTC test rig.
- 1 kWh TES tank, including its connecting pipe system, was insulated and charged up to 300 °C using heat transfer fluid (HTF), and its charging performance was subsequently examined.
