The world’s largest demonstration plant for a new kind of renewable energy storage is up and running in the west of the China. Called liquid-air energy storage (LAES) the plant uses renewable electricity to compress air to extreme densities until it turns to liquid. It can then be rapidly released to power a turbine and discharge that green energy back into the grid.



Thanks for this article that is much better than the original one from the post … although it is still limited in regards to the (obvious) separation of gases when in liquid phases. Yet, it does hint at that separation by saying :
We see why they keep their industrial secrets simply reading what they disclose as their source (from China) :
