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.



You are right but the article was wrong on the low temperature and “liquid air” point.
To know more i read a little bit here :

it shows my comment was right as well.
No, the entire point is that it’s a new liquid process type, not the traditional compressed only. That’s the news.
