One possibility is to simply bury the (top of the) tanks more than about 6m deep (since the temperature gradient moves about 1m/month) and let the surrounding soil add to the thermal mass of the store providing that there is nothing to carry excess heat away such as moving groundwater...

Anyway, yes, sounds like you have your seasonal store right to hand!  You might be more interested in the summer-cooling possibilities than me too.

Google "slab on grade" for how ~2" thick poly foam can be used to insulate a slab foundation. As absurd as it seems, you could insulate a few feet below the surface to reduce your required digging depth.

At any rate, it certainly is an interesting crackpot scheme.
