With reports about climate change becoming increasingly dire, it’s increasingly important to find an eco-friendly way to not only generate energy, but also store it. After all, wind turbines and solar power and the like don’t run steadily. So we can’t just stick that extra energy in a bottle to use when the wind dies down and the sun sets.
Only no, that’s almost exactly what a group of Scottish scientists is proposing. Except, in this case, the bottle is a layer of porous rocks deep within the sea bed, and the energy comes from compressed air. You simply use your renewable energy source to compress and store the air, and then when you need the energy again you pop the cork, so to speak, and let the escaping air drive a turbine that re-generates the electricity. (Thanks to the extreme pressures down there, the air would stay in place, ...
