The world’s largest sand battery has been opened in Finland and is capable of storing large amounts of energy from renewable sources such as solar and wind.
The 13-meter structure, located in the South Municipality of Porn this, is capable of storing 100 MWh of energy-enough to provide energy to approximately 10,000 homes for one day.
The thermal storage system, built by Finnish Polar Night Energy, works by warming low -grade sand with excess power generated by renewable energy.
The sand can then store this heat at a temperature of about 500 degrees Celsius for the same time until the network needs electricity again.
If necessary, the battery releases warm air sand, which is used to heat water for the local heating network.
Hot water is used to warm up houses, offices, schools and pools in the Kankaanpää district, replacing the old wooden wood power plant and reducing carbon emissions by about 70 %.
“These facilities are now operational and provide affordable regional heating,” said Lisa Nascali, CEO of Polar Energy.
“We have shown that there are cost -effective solutions for heating, just investing.”
Polar Night Energy says the technology offers enormous potential for providing cost -effective and clean energy for storage markets around the world.
Another experimental project is scheduled to begin in Valkeakoski in the coming weeks, and Finland launched an ideal test after Russia stopped gas and electricity in 2023.
Finland also goes to carbon neutrality over the next 10 years before reducing greenhouse gases by more than 90 % by 2050.
“Energy storage plays an important role in energy transfer, where combustion -based production disappears and society moves to carbon neutrality,” said Sari Molla’s Minister of Environment and Weather at the opening of the sand battery.
“Porn this sand battery is a great example of how cleaning through the electricity of the area’s heating networks.”
