How sand batteries could change the rules of the energy storage game

The future of the energy sector has always been associated with the need to accumulate capacities and use them as needed efficiently. Mankind is constantly looking for ways to conserve energy. Among them are lithium-ion batteries, gas storage, pumped storage hydropower, and gravity energy storage systems. All options have their advantages and disadvantages, so scientists do not stop looking for new technologies and methods.
For example, to store energy, literally, in the sand. How can the world's first commercial sand battery installed in Finland be a game changer in green energy storage? Find out about it in today's video! The advancement of "green" energy, in particular, solar and wind, poses several challenges, the most important of which is how to efficiently store "clean" electricity as the sun and wind cannot be turned at will. Definitely, it would be possible to build huge lithium-ion batteries, as Elon Musk's company did for the Australian government in 2017. But such projects have many disadvantages.
First of all, the cost of the battery.
