Massive underground salt crystals are used to store energy for entire continents
Deep beneath the Earth's surface, massive salt caverns act as geological batteries, storing trillions of watt-hours of energy to ensure entire continents remain powered through the harshest winter months.
Engineers utilize the unique impermeability of rock salt to create massive underground storage vessels capable of holding natural gas at pressures up to 250 bar. Unlike porous sandstone, these salt crystals provide a perfectly airtight seal that prevents leaks.
