Finland continues to surprise the world with its technological advances in terms of energy transition. Therefore, Recently. However, the country inaugurated in Pornainen the largest battery of sand ever built, an ambitious project led by the start-up Polar Night Energy. However, This impressive installation uses approximately 2,000 tonnes of crushed steatitis to store up to “they store energy sand”: finland 100 heat megawatt hours from renewable electricity. Consequently, With a height of 13 meters. Consequently, a width of 15 meters, it provides a continuous thermal power of 1 megawatt, allowing the town to be heated throughout the winter and considerably reducing its carbon emissions.
A technological rise – "they store energy sand": finland
Pornainen’s battery represents a major advance in the field of thermal storage. In addition, It is ten times larger than the first commercial installation of Polar Night Energy, located in Kankaanpä. Furthermore, Connected to the LVIISAN Lämpö urban heating network, it is now essential for the heat supply of the municipality. However, Thanks to this innovation. Furthermore, Pornainen was able to eliminate the use of fuel oil for heating and reduce the consumption of wood chips by 60%, thus relegating the biomass boiler to a secondary role during peaks of demand.
The operation of this battery is based on the use of renewable “they store energy sand”: finland electricity in excess to heat air. which then circulates in tubes crossing the steatite. The latter is brought to temperatures between 500 and 600 ° C. The reinforced insulation of the enclosure makes it possible to keep this heat over several weeks, even several months. When a need is felt, hot air is returned to heat the water from the urban network. In practice, the battery is continuously recharged as soon as renewable electricity is available in surplus. According to Polar Night Energy. this technology allows Pornainen to get climately closer to climate neutrality by 2035, with an annual reduction in CO₂ emissions estimated at 160 tonnes.

Steatite. a strategic choice – "they store energy sand": finland
Traditionally, sand is the reference material for this type of batteries. However, Polar Night Energy chose crushed steatite, a by-product of the Finnish chimneys Tulikivi. This rock has a higher thermal conductivity than that of sand, thus improving the overall efficiency of the system. In addition. its use is part of a logic of circular economy, valuing industrial waste while offering a competitive storage solution.
System performance is based on thermal storage efficiency of up to 99%. with losses limited to 10-15% during load and discharge cycles. The battery maintains temperatures up to 400 ° C, meeting the requirements of urban heating. For Polar Night Energy. the choice of material is always made according to the specific needs of the customer, taking into account physical properties, “they store energy sand”: finland profitability and sustainability. “We systematically select the thermal energy storage support according to the expectations of our partners. while integrating the performance and cost criteria,” underlines Markku Ylönen, co -founder of the company.

Environmental impact. perspectives
The environmental impact of this sand battery is significant. By reducing CO₂ emissions of 160 tonnes per year, Pornainen is positioned as a model commune in terms of sustainability. This installation not only reduces the local carbon footprint, but also to promote the use of large “they store energy sand”: finland -scale renewable energies.
With such an advance, Finland once again demonstrates its commitment to innovative and sustainable solutions. This project could serve as a model for other regions of the world seeking to reduce their dependence on. fossil fuels. Polar Night Energy is already planning to extend this technology to other municipalities. thus strengthening its pioneer role in the sector.
A viable economic model
The economic viability of this technology is based on several key factors. The use of steatitis as a basic material helps reduce costs while increasing efficiency. In addition, the circular economy implemented ensures optimal valuation of local resources.
The economic model developed by Polar Night Energy may well be a solution for the future for communities seeking. to invest in sustainable energy infrastructure. With a significant reduction in heating costs. a decrease in carbon emissions, this technology turns out to be both ecological and profitable. How “they store energy sand”: finland will this Finnish innovation inspire other countries to adopt similar solutions for a greener future?
