Finnish researchers have installed the world’s first fully functional sand battery, which can store green energy for year-round supply.

Climatic change has been one of the most critical issues of the era, affecting all the living creatures on the planet. The matter is of utmost importance, so governments worldwide are constantly looking for renewable energy sources to lessen carbon emissions. The sand battery installed by Finnish researchers can be the solution to all the problems as it can store power for several months.

The researchers said that the sand keeps the heat at about 500C. The device is heated using low-grade sand and inexpensive electricity generated by wind or solar power. It can be stored and used during winter when energy is more expensive. The main component of this apparatus is a silo which is filled with about 100 tons of building sand.

After Finland joined NATO, Russia halted electricity and gas supply, raising concern over the source of heat and light in the country. Indeed this tiny power plant with the new technology to store power can be a hope to ease some worries in Finland
