Polar energy storage power supply

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.

Who is polar energy solutions?

Polar Energy Solutions has been founded to meet these challenges and strengthen the future energy system. The company delivers capacity solutions and support services that ensure stability, security, and reliability in local power grids.

What is polar energy?

Polar Energy is technology-agnostic and invests in the solutions best suited for each specific need — whether that involves balancing power, storing energy, or adding more capacity. When additional power is required, it is generated through gas engines or turbines powered by locally produced renewable biogas.

What is polar night energy?

It can be charged with low-cost grid electricity or self-generated power, and enables participating in grid balancing markets for additional revenue. 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.

How does polar night energy sand battery work?

Polar Night Energy said its Sand Battery works as a high-power, high-capacity reservoir for excess wind and solar energy, storing energy in sand as heat. The new Sand Battery in Pornainen will be filled with crushed soapstone, a by-product of Tulikivi’s heat-retaining fireplace production.

When will polar night energy sand battery be commissioned?

Testing of the Sand Battery will begin during the winter, with commissioning set for 2025. In 2022, Polar Night Energy switched on the world’s first commercial sand-based, high-temperature heat storage system in the Finnish city of Kankaanpää, with 100 kW of power output and 8 MWh of storage capacity.
