How does polar night energy's thermal energy storage work?
Polar Night Energy’s thermal energy storage powers the change from fossil fuels to renewable energy. How does it work? The Sand Battery provides low-emission energy, supporting the expansion of solar and wind power without toxic or harmful materials. Our thermal energy storage ensures high security of supply and increases energy self-sufficiency.
What is a polar night energy sand battery?
Seeing the limitations of water systems for energy storage, Polar Night Energy had an alternative solution: “We use really, really hot sand as the storage medium.” The PNE sand battery is capable of providing heat at the extremely high temperatures required by the process industries, unlike water storage systems.
What can polar night energy do for You?
Polar Night Energy’s solution can be adapted and scaled for various energy systems, utilizing cutting-edge technology to optimize energy production, storage and distribution. Decarbonize your industrial processes with our innovative Sand Battery technology.
What is a polar night energy heat transfer system?
Part of the heat transfer system installed by Polar Night Energy in Tampere, Finland. The vertical pipes at left are part of the heat exchanger, while the resistive heater elements are wrapped in white insulation at right. Between these components is the air-circulating radial blower.
Where is polar night energy located?
The nation of Finland, part of which is above the Arctic Circle. Polar Night Energy's heat storage systems are currently installed in the cities of Tampere and Kankaanpää. Big problems demand big solutions, and there is perhaps no bigger 21st-century problem than climate change.
Why does polar night energy need simulation software?
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. We need predictive modeling to answer as many questions as possible, before we commit to assembling all this equipment — and all this sand!”
