#EnergyTransition #SandBattery - World’s Largest Sand Battery achieves its targets – Emissions reduced by 70% - "The Sand Battery built by Polar Night Energy for Loviisan Lämpö has now been in operation for one year. With the help of the Sand Battery, climate emissions from the Pornainen district heating network have been reduced by 70 percent. The technology also has significant potential to reduce emissions in industrial applications. The world’s largest Sand Battery was commissioned in Pornainen, Finland, in June 2025. During its first year of operation, the Sand Battery has met all performance targets and design specifications set for it. It serves as the primary production facility for the local district heating network." - Polar Night Energy https://polarnightenergy.com/news/worlds-largest-sand-battery-achieves-its-targets-emissions-reduced-by-70/

Die #Sandbatterie hat den Ölverbrauch beendet, den Einsatz von Biomasse verringert und die Emissionen des Fernwärmenetzes um 70 Prozent reduziert.
Das Unternehmen will auf diesem Erfolg aufbauen und arbeitet bereits an einer noch größeren Anlage.

A town in #Finland has built the world’s largest #sandbattery, using 2,000 metric tonnes of crushed soapstone to store #heat. This innovative solution provides #cleanenergy for the town’s #heating needs, significantly reducing carbon emissions and reliance on fossil fuels. The sand battery technology offers a promising solution to the challenge of renewable energy intermittency, with potential for global replication. https://www.cnbc.com/2026/07/25/finland-sand-battery-renewable-energy-storage.html?eicker.news #tech #media #news

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."

When wind power is abundant and spot prices are negative (which occurs in Finland about 700 hours per year, including winter) this #sandBattery takes excess electricity off the grid, stores 250 megawatt-hours (MWh) heat in hot sand, and afterwards feed 2 megawatts (MW) into the #districtHeating grid

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."
