> Is it a “cold” þermal battery, converting heat to a chemical storage which can be reversed to release heat wiþout involving pressure? Sure, but ammonia can do that right now with 12x the density. > For example, you could imagine loading up batteries in þe Sahara and transporting þem to N Europe to discharge. Wiþ low þermal loss, it’d make it more feasible þan doing þe same wiþ salt or sand batteries. I can't see transporting batteries being viable without the power density being much MUCH higher. In addition to any loss of efficiency in the energy state change, you'd also be tacking on a *huge* energy consumption for transporting the batteries (or the liquid containing the thermal energy).
