How a Sand Battery Could Revolutionize Home Energy Storage. Use code UNDECIDED50 to get 50% OFF First Box and free wellness shots for life with any active subscription at https://bit.ly/3TiVmO8! Sand. It’s coarse, it’s rough, and it can make for a great sand battery. And as weird as that might sound, it’s just one example of the many earthy materials currently used for thermal energy storage (or TES). A while back, we covered the debut of the world’s first commercial sand battery, which is big enough to supply power for about 10,000 people. Now, sand-based energy storage has reached a new frontier: individual homes. Companies like Batsand are currently offering heat batteries that bring hot and fresh sand directly to your door. Seems you can get just about anything delivered these days.
But what’s stopped us from experimenting with residential TES before? How will heat storage impact our lives in our homes? And where exactly are homeowners supposed to put this stuff?

The most efficient solution for storing solar energy is to extract energy from the ground with a ground source heat pump, like Matt has.
This solution has the lowest CO2 emissions.
The next step would be to supplement the system with an air source heat pump that only runs when the outside temperature exceeds the earth's temperature.
What I really want is a heat battery that will store heat for about 6-9 months. At that point, I can hold all the heat from summer over to warm my house in winter and then use the cold from winter to cool my house in summer. Alas, thermodynamics and heat insulation limits make that a pipe dream. Current systems are only good for a few days at best as the heat leaks away: they're really designed just to level out daily heating loads, not annual heating and cooling loads.
i misread "bastard" and i thought it was a good product name
If it only reaches 40°C then that water is nowhere Safe, similar issue exists with Heatpumps. The Energy savings in ideal conditions don't matter as you will rarely ever operate in those conditions for any length of time and even if you were you'd need to come up with 15°C-20°C to keep the Water safe for Human use.
we in Malaysia had abundant of solar sunshine and rain all year round. We did not fully utilized this gift yet we keep on making so much of noise on gas fuel prices yet never willing to try on alternative energy. Sometimes people which live in a colder climate tend to have a clever brain. They able to use every single drop of resources available without waste.
One of the best videos on Youtube. Genius idea, thanks for sharing.
Worthless here in the northern Chihuahuan desert where we usually have only 2 months of cool, and rarely what anyone anywhere else in the country would describe as "cold" weather. We spend nearly all of our energy on air conditioning. While you could use sand to power a gas-absorption system, these systems are extremely expensive and would require many years to recover their cost. Just thought out how different life is in the desert southwest on many levels.
We have been doing that with geothermia
Great vid. A lot of homes such as mine are built on a slope. We could have easily hid a Batsand or two under the back end of the house with minimal installation cost.
Why was the pyramids built around all that sand?
الترجمة ممتازة جدا جدا جدا ❤❤❤
Salt batteries for home also makes a lot of sense.
Could we maybe pick something that we're not already rapidly running out of for the basis of future technologies?
"You're using most of your energy to heat your home" I like how the whole video just pretends Summer isn't a thing
i thought the world is running out of sand
Finally, you cover something that is actually viable, not like the heat pump estuary!!!! ,
I dont like sand, it's corse, rough and irritating and it gets everywhere.
-Anaking Skywalker
Does it matter what type of sand?
Bravo……black plastic……no go………factor………cheers
I think sand would be more versatile for colder climates, coming from an architectural perspective, my mind immediately goes to the idea I would prefer to pitch sand over water with a client
Why is it so cold in the desert at night?
I have an on demand water heater. I hate it but its way more efficient than a regular water heater.
I'd love to see how this technology matures
Have you thought about using a sterling motor with your sand battery?.
Might as well just go with a salt battery cause you can actually get electricity out of it.and salt holds heat pretty good too.
its just a thing U put it uder the bilding…
Im going to build one that just burns your house hold cardboard and paper garbage, i will show you how to NOT buy into solar
How can one switch off the AI-generated translation? It is awful to watch.
Sorry but Im already paying 25 per month to avoid commercials. Goodbye.
