Tobberone

I’d rather that than landfill, though. Today the tree tops, tomorrow the stars, as they say:)

I honestly thought it would be bigger. Having said that, we (as in the municipality i work for) currently have 40-60 MWh sand batteries in production. The first, small and hot, one is currently charging to go into production when it gets colder. The bigger and colder battery is slated to start charging the next season.

“And you can store it for long periods, not just two hours or four hours like lithium-ion batteries, but potentially for days and maybe even weeks.”

I’m guessing here, but “for days and maybe even weeks” must be because the battery is above ground? With good insulation seasonal storage is very much in the cards.

A day care in another Swedish municipality use about 1/5 of the “normal” energy for heating thanks to a sand battery. As in 15-18 kwh/m2/year as opposed to 70 kwh/m2/year as is the current upper limit for new buildings in Sweden.

As bad as things are, I’m still glad that the oil wars are driven by greed and not scarcity. Had the option been mad max things would have been so much more desperate, as things stand, a world with energy and hope is still an option.

I would think that the graph would be rather different had it been “last kilometer”? I’d expect to see electricity at the bottom there.
