New Energy Battery Power Loss in the Northern Night

Can thermal sand batteries produce electricity?

Finnish firm Polar Night Energy developing a new sand battery with Power to Heat to Power (P2H2P) capabilities, allowing stored heat to be converted back into electricity. Image: Polar Night Energy Finnish firm Polar Night Energy will investigate the feasibility of producing electricity from its thermal sand batteries.

Where is polar night energy's sand battery coming from?

Here's another for the pile, coming out of Finland. Polar Night Energy says it's just opened its first commercial sand battery at the premises of "new energy" company Vatajankoski, a few hours out of Helsinki.

What is polar night energy?

Polar Night Energy says it's developed and commercialized a super-cheap, super-simple way of storing energy for anywhere between hours and months, simply using heated sand. Its first 8-megawatt-hour thermal battery has gone online in Finland.

What is a polar night Energy Tower?

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.

Could polar night replace carbon-burning heat sources?

As such, Mission Innovation's climate solutions framework has estimated estimated that deploying Polar Night's energy storage system to its full potential could replace enough carbon-burning heat sources to reduce annual greenhouse emissions by somewhere between 57 and 283 megatons of CO2 equivalent per year by 2030.

How long will a solar battery last in Pornainen?

The battery’s thermal energy storage capacity equates to almost one month’s heat demand in summer and a one-week demand in winter in Pornainen, Polar Night Energy says. Construction and testing of the 13 metres high by 15 metres wide battery is estimated to take around 13 months, meaning it should be keeping residents warm well before winter 2025.
