How a Sand Battery Could Revolutionize Home Energy Storage. 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.
