Zeolite Thermal Storage Retains Heat Indefinitely, Absorbs Four Times More Heat Than Water
6th June 2012
Zeolites (literally “boil stones”) aren’t exactly new: The term was coined in 1756 by Axel Cronstedt, a Swedish mineralogist who noted that some minerals, upon being heated, release large amounts of steam from water that had been previously adsorbed. For the last 250 years, scientists have tried to shoehorn this process in a heat storage system — and now, the Fraunhofer Institute, working with industrial partners, has worked out how to do it.
