Are you sure sunamp is molten salt? To me, molten salt is to store energy at a very high temperature in insulated containers.
I thought sunamp is some kind of room temperature phase change material that does not require heavy insulation.
- iainmerrick 8y agoI’m not at all sure, you’re almost certainly right. (Not knowing much about the chemistry, I’m naively conflating the two) Edit to add: Sunamp has non-zero heat loss, so it must be stored hot rather than room temperature, but it might not be very hot.
- ogrisel 8y agoThere are other alternative technologies to store energy as heat, in particular molten silicon: - https://reneweconomy.com.au/mit-team-gains-ground-on-molten-silicon-energy-storage-concept-23077/ https://reneweconomy.com.au/mit-team-gains-ground-on-molten-... - https://1414degrees.com.au/ https://1414degrees.com.au/ (which looks like a competitor for malta)
- dangravell 8y agoWas going to mention Sunamp. It does use a PCM, and that is described as a salt so maybe it's where the confusion comes from. It also has far better insulation than equivalent devices (hot water cylinders). Typically VIPs, although I've read a few reports about the casing being compromised recently and that wouldn't play nicely with the panel.
- iainmerrick 8y agoYes, I glommed onto the use of “salt” in both cases and figured they were similar.
