World''s First Large-scale Sand Battery Goes Online in Finland
The battery, located in the town of Kankaanpää, is attached to the district heating system. The battery is made of a four-metre by seven-metre steel container that contains hundreds of tonnes of sand. The sand is heated to a temperature of between 500 and 1,000 degrees Celsius using renewable electricity.

Sand Battery: An Innovative Solution for Renewable Energy
In a sand battery, sand is heated using renewable energy sources such as wind, solar, or geothermal energy during off-peak hours when energy demand is small. This stored thermal energy can then be used during peak hours when energy demand is high. The sand battery has numerous advantages over other thermal energy storage solutions, such as its

What is a sand battery?
The Sand Battery efficiently stores large amounts of intermittent energy for extended periods and returns it as highly valuable heat when needed. Polar Night Energy’s Sand Battery is a large-scale, high-temperature thermal energy storage system that uses sustainably sourced sand, sand-like materials, or industrial by-products as its storage medium.
How does sand become a battery?
The sand becomes a battery after it is heated up to 600C using electricity generated by wind turbines and solar panels in Finland, brought by Vatajankoski, the owners of the power plant. The renewable energy powers a resistance heater which heats up the air inside the sand.
What is the world's biggest sand battery?
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.
Could sand be a viable battery for green power?
Other research groups, such as the US National Renewable Energy Laboratory are actively looking at sand as a viable form of battery for green power. But the Finns are the first with a working, commercial system, that so far is performing well, according to the man who's invested in the system.
Can a sand battery save energy?
For applications where high-temperature energy is needed, for example in the wood and construction industry, bakeries, laundries and machine shops, a sand battery can be a viable solution. The heat demand of industry in Finland alone is twice as much as the use of district heat, so the emission reduction potential of the sand battery is huge.
Is a sand battery better than a lithium battery?
The Polar Night Energy team acknowledges this but argues that a sand battery is a far more cost-effective solution. The team has calculated that their battery is eight to 10 times cheaper than a lithium battery which stores the same amount of energy.
