7 Jul 2026 I thank the Renewable Thermal Collaborative (RTC) for organising a webinar highlighting some of the recent achievements of thermal energy storage technologies. Conceptually thermal-energy storage is quite simple. You heat up a material and it stores energy either in the form of sensible heat, latent heat (phase change) or thermochemically. At medium grade, with temperatures of up to 400C, these systems are hard to beat as they can provide industrially useful heat. This stored heat is highly valuable in food processing and bio refining industries because process temperatures rarely exceed 200C. Besides food processing there are several other industries that can use medium grade heat for drying and preheating. Since heat is used in all industries, it is the single unifying theme of the entire manufacturing sector and residential too because many electrical appliances are performing temp control work. Thermal energy storage technology is ther...
2 Jul 2026 Great honor to be a part of discussion led by Prof Vasi,Electrical Engg,IIT Bombay on industry academia collaboration. Research has always had to and will always have to balance funding from government and industry while pursuing something that is truly novel ,yet can have practical applications in the future. Directed research has its merit. But nothing beats original ,curiosity driven enquiry. Majority of science and all of its transformative ideas that we take for granted today were discovered by people who were merely following their curiosity and not thinking about immediate applications. Those came decades later. All pioneers were explorers — they built new fields where no expertise existed. Fundamental research carries with it the potential to create new industries, it's difficult to put a dollar value on it and it can't exactly be funded in the same way as a typical R&D lab with a fixed outcome or a deliverable. Scientific inquires can be a...
