6 FAQs about [Finnish solar energy storage system]
Does Finland have a sand battery?
Finland begs to differ. This month saw the Nordic nation launch the world's first commercial "sand battery". About 230 kilometres north-west of Helsinki, in the town of Kankaanpää, homes, offices and the public swimming pool are being heated by thermal energy stored in a 7-metre steel container filled with 100 tonnes of sand.
Can a heat storage system serve more buildings in Tampere?
For example, Eronen mentions the specifications of an expanded heat storage system that would serve more buildings in Tampere. The team calculated that supplying heat to a district of 35,000 people would require a sand-filled storage cylinder that is 25 meters tall and 40 meters in diameter.
Does Finland have green power?
Finland gets most of its gas from Russia, so the war in Ukraine has drawn the issue of green power into sharp focus. It has the longest Russian border in the EU and Moscow has now halted gas and electricity supplies in the wake of Finland's decision to join NATO.
Does Finland need a district heating system?
"It's very useful in Finland where we have cold winters and need heating pretty much from September to May, [due to] an average annual temperature of under 10C (50F)," she says, adding that half of Finland's 5.5 million people are connected to a district heating network.
What makes polar night energy sand-based heat storage system so important?
Simulation image of natural convection effects through ductwork inside the sand storage vessel. The sheer scale of Polar Night Energy’s sand-based heat storage system makes simulation software indispensable. “We cannot possibly build full-size prototypes to test all of our ideas.
What is particle thermal energy storage?
Particle thermal energy storage is a less energy dense form of storage, but is very inexpensive at $2 to $4 per kWh of thermal energy at a 900°C charge-to-discharge temperature difference. The energy storage system is safe because inert silica sand is used as storage media, making it an ideal candidate for massive, long duration energy storage.
