Polar Night Energy is a Finnish startup that designs and manufactures high temperature thermal energy storages. The Sand Battery developed by the company enables a significant increase in wind and solar energy production while reducing the use of fossil fuels. The company was founded in 2018.
Finland ''s Polar Night Energy has secured €7.6 million ($8.2 million) in seed funding. The startup, known for its thermal energy sand-based storage systems,
Polar Night Energy''s sand-based high temperature seasonal heat storages may save over 100 Mt CO2e per year in 2030 according to Mission Innovation''s report. The amount is approximately 3% of the current
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 heating power and 8 MWh
The world''s first sand-based thermal energy storage system goes into operation in Western Finland. Polar Night''s unit is a steel container of approximately four meters wide and seven meters high. FOR THE FIRST TIME, sand is being used to store thermal energy thanks to the work done by Polar Night Energy, a Finnish company.
It''s quite a simple structure to begin with, Polar Night Energy said of its prototype. A tall tower is filled with low-grade sand and charged up with the heat from excess solar and wind electricity.

The first commercial sand-based thermal energy storage system in the world has started operating in Finland, developed by Polar Night Energy. Polar Night Energy''s system, based on its patented technology, has gone online on the site of a
Vatajankosken Sähkö and Polar Night Energy have signed a preliminary agreement to construct a sand-based heat storage with 100 kW heating power and 8 MWh capacity. It would provide heat for Vatajankoski''s district heating network in Kankaanpää, Finland. Vatajankosken Sähkö and Polar Night Energy h
See below for Finnish. Polar Night Energy is developing the world-renowned Sand Battery towards Power-to-Heat-to-Power (P2H2P) capabilities – a cutting-edge system that converts excess renewable energy into heat, then back into electricity. The company will
To aid international expansion plans, Polar Night Energy is looking at replacing sand with other granular, non-flammable materials in places where there''s a shortage of sand.
Polar Night Energy''s sand-based high temperature seasonal heat storages may save over 100 Mt CO2e per year in 2030 according to Mission Innovation''s report. The amount is approximately 3
As a material, sand is durable and inexpensive and can store a lot of heat in a small volume at a temperature of about 500–600 degrees Celsius, says Polar Night Energy''s CTO Markku Ylönen. Vatajankoski is happy to co-operate with Polar Night Energy in testing and validating the first-of-a-kind high temperature heat storage unit as
Finnish companies Polar Night Energy and Vatajankoski have built the world''s first operational "sand battery ", which provides a low-cost and low-emissions way to store renewable energy. The
We use sand as the storage medium, which leads to safe operation and a natural balance in the storage cycle. Additionally, sand is a cheap and abundant material, which can be
Polar Night Energy heat storages can be connected to most heat transfer systems and are compatible with heat pumps. The system can produce hot water for water-circulating systems, or hot air and process steam for industrial
