MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202521118546 A) filed by Dr. Vishwanath Karad Mit World Peace University, Pune, Maharashtra, on Nov. 28, 2025, for 'solar energy storage capsule using phase change material.'
Inventor(s) include Prof. Dr. Anita Nene; and Prof. Dr. Rohit Ghadge.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a solar thermal energy storage capsule system (100) comprising a Scheffler solar concentrator (102), a receiver, and a detachable tube (104) containing phase change material (PCM) (106). The Scheffler solar concentrator (102) is configured to direct concentrated solar flux to the receiver, which contains water and heats it to elevated temperatures. Heated water is transferred to a thermal storage capsule, where it surrounds the detachable tube (104) arranged in a cantilever configuration within a shell. The tube (104) contains PCM (106), preferably paraffin wax, which stores latent heat during charging. The shell includes a water jacket to facilitate heat transfer and is insulated with polyurethane foam to minimize thermal losses. The tube (104) is removable and configured to discharge stored thermal energy for heating water when solar energy is unavailable. The system provides heated water at approximately 75 C for a capacity of about 15 liters."
