PCM briefing: Epsom salts for seasonal heat storage; Formato joins Microtek Labs

Ben Welter - Monday, April 16, 2018

Chris Sansom, an associate professor in concentrating solar power at England's Cranfield University, says that magnesium sulphate heptahydrate, or Epsom salts, could be a viable material for seasonal heat storage. Adding water to the salts causes a reaction that creates heat at around 80 degrees C, a good match for space heating and hot water. Sansom is developing a heat storage system for the university’s growing campus. Because the school's CHP system requires a temperature of 90 degrees C, a slightly different form of salt, magnesium nitrate hexahydrate, will be used.
