Rambabu, Ghulewadi, Maharashtra, on March 10, for 'thermal energy storage device using phase change materials for renewable energy systems.'

Inventor(s) include Mr. Pawar Shekhar Gangadhar; Dr. Manubolu Venugopal Naidu; Dr. P. Sivakumar; Mr. Amol Somnath Parkhe; Dr. S. Devaraj; Dr. Sachin Vyasrao Mutalikdesai; Mr. Bodhe Vaibhav Sakharam; Mr. Gavhane Ganesh Vishwanath; Dr. Pappu Kumar Harijan; and S. L. Rambabu.

The application for the patent was published on May 1, under issue no. 18/2026.

According to the abstract released by the Intellectual Property India: "The present invention relates to a thermal energy storage device utilizing phase change materials for efficient storage and release of thermal energy generated from renewable energy systems. The device comprises a containment structure housing one or more phase change material modules configured to absorb and store latent heat during phase transition and release the stored heat during solidification. A heat transfer mechanism including channels or conduits circulates a heat transfer fluid to transfer thermal energy between the renewable energy source and the phase change materials. The device further includes thermal conductivity enhancement elements such as fins or conductive matrices to improve heat transfer efficiency, and insulation layers to minimize thermal losses. Additionally, a monitoring and control system with sensors regulates thermal charging and discharging operations. The modular design enables scalable deployment in solar thermal systems, geothermal installations, and waste heat recovery applications, thereby improving renewable energy utilization and system reliability."
