Here’s a giant “battery of sand” that could come in very handy in the future

Must read

We know that solar power (the cheapest in history), wind, hydroelectric and other renewable energy sources can provide unlimited energy… world capacity to store sees some logistical problems. From this perspective, research became indispensable and a new idea emerged.

We’re talking about a.sand cell” It stores the energy, the excess energy generated by the wind and the sun, in the form of heat in a large sandbox to be discharged when needed. While the storage capacity is 8 megawatt hours of energy, it can discharge approximately 200 megawatt hours of energy in kilowatts and store it for months.

The main task is to use it as a high-power, high-capacity storage tank for excess wind and solar energy. Energy is stored in the form of heat, which can be used to heat homes or provide hot steam and heat for industries that are often dependent on fossil fuels.“It writes Polar Night Energy (PNE) in a statement.

To be clear, storing energy in the form of heat is not a new idea, but hiding it in the sand can be a pretty effective solution. In fact, the material has a significantly higher boiling point and can store much more energy than a similarly sized water tank.

PNE company already Such a big battery in a small town called Kankaanpää in western Finland, where it helps to heat homes and a local swimming pool. By the way, here are two drops of water-powered batteries in order not to prolong the matter.
