Called liquid-air energy storage (LAES) the plant uses renewable electricity to compress air to extreme densities until it turns to liquid.

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.

    … is up and running in the west of the China.

    No. “in Chinas’ west ?” or " … ?" idk.

    When electricity is plentiful, it powers machinery that draws in air, compresses it and cools it to extremely low temperatures of around -190°C. At this point, the air becomes a liquid, taking up far less space than it did as a gas.

    No. Liquid fractions of gases from air readily separates. So O2(l), N2(l), Ar(g), and many other, each being much more valuable alone. Helium for example is very expensive.

    (So, economically speaking, only the nitrogen should be expanded back to retrieve stored energy.)

    in my opinion, this article could have been much better even if written by artificial intelligence.
