The next big #EnergyStorage device could be a 1000 °C #SandBattery
With high specific heat, low thermal conductivity, and no risk of fire, sand-based energy storage systems are gaining traction in grid-scale and industrial heating applications.
by Georgina Jedikovska, Jul 17, 2025
Excerpt: "While at first glance, sand might not seem like the most high-tech solution for energy storage, its ability to capture and retain heat has been harnessed for millennia.
"Sand might not seem high-tech, but its thermal properties have been used since antiquity. #AncientEgyptians mixed sand, silt, and straw to construct homes that absorbed solar heat by day and slowly released it by night.
"Today’s engineers are taking that principle further using refined materials, insulated steel silos, and precision heating systems to build high-temperature thermal energy reservoirs using sand."

How 2,000 Tons Of #Sand Stores 100 Megawatt-Hours And Slashes Carbon Emissions 70%
By John Koetsier, Apr 14, 2026,
"#PolarNight is doubling its size with a new 250 megawatt-hour facility in Vaaksy, #Finland, which will output 2 megawatts of energy consistently. That newer and bigger battery will use only slightly more sand – 2,400 tons – because the #SandBattery’s design renders it more efficient with size. What will become the new world’s largest sand battery is already under construction and is scheduled for completion in summer 2027."

Anyone have an electric burner element? I'm ready to start experimenting with a #SandBattery to store excess solar as heat to radiate into my space at night.
I have a water heater element, but I understand those can burn out easily because they're intended to be submerged in water all the time.

Finland has launched the world’s largest sand battery, a groundbreaking energy storage system that can store heat for months and power an entire town for a week. Finland’s sand battery helps stabilize the energy grid, ensuring renewable sources like wind and solar can still provide power during periods of low generation.
Sand batteries could become a key player in solving the renewable energy storage crisis.

World's first '#SandBattery' can store heat at 500C for months at a time. Could it work in Australia?
By technology reporter James Purtill
Mon 18 Jul 2022Excerpt: "Polar Night Energy's chief executive officer Markku Ylönen said the entire battery could be built in "any steel workshop".
" 'It's really a typical #silo with nothing that special,' he said.
"To discharge the stored #ThermalEnergy, air is circulated through pipes in the sand where it's heated, then directed, to wherever it's needed.
"Right now, that's mostly heating homes, but it could also be used for high-temperature industrial processes, Mr Ylönen said."

WOW, how research in energy storage pays off: #Sand #Batteries.
The sand battery is simplicity itself. “We just heat air and circulate it through sand,” says Liisa Naskali, COO of Polar Night Energy. Sand, or other material crushed to sand-size, has the ability to store heat for weeks. Unlike other batteries, the system doesn’t rely on chemicals, doesn’t degrade, and won’t catch on fire. In operation, the sand battery has demonstrated a round-trip efficiency of 90%.

Here's a working sand battery in Finland. Heated to 500°C, it'll store heat for up to three months. This one heats all the town's municipal buildings, uses no chemicals, it doesn’t degrade and won’t catch on fire.
Seriously cool tech!

love both #energyStorage and #sand :,D
"#PolarNightEnergy has built an industrial-scale sand battery in Pornainen #Finland. The #battery is set to reduce #carbonemissions from the local #heating network by as much as 70%. At 42 feet tall and 50 feet wide, the battery can store up to 100 MWh, enough to heat the whole town for a week. The #sandbattery can hold a charge for months at a time, helping balance the energy #grid during periods of high demand."

‘A very Finnish thing’: Big #SandBattery to store wind and solar energy using crushed soapstone
The battery will be able to store a week’s heat demand in winter - how does it work?
By Lottie Limb
Published on 10/03/2024"A huge sand battery is set to slash the carbon emissions of a Finnish town.
"The industrial-scale storage unit in Pornainen, southern Finland, will be the world’s biggest sand battery when it comes online within a year.
"Capable of storing 100 MWh of thermal energy from solar and wind sources, it will enable residents to eliminate oil from their district heating network, helping to cut emissions by nearly 70 per cent.
" 'It's exciting to build a large-scale thermal energy storage, which will also act as a primary production plant in Pornainen's district heating network,' says Liisa Naskali, COO at Polar Night Energy, the company behind the innovation.
" 'This is a significant step in scaling up the sand battery technology.' "

I've shared a few notes about these sand-based heat batteries before, but this is a cool (pun intended) development: instead of sand, using the waste rock material from soapstone fireplace manufacturing for a 100 MWh installation that enables the municipality to remove oil burners and replace them will surplus electricity stored as heat.
