      This is a hilarious breakthrough.

      Lithium-ion batteries require lithium, cobalt, and nickel materials that are expensive, hard to mine, and environmentally damaging. This battery uses nothing but air. It is 100% recyclable, has a lifespan of 30-40 years.

      China is essentially breaking out of the rare earth monopoly they essential control.

      >The facility, located outside Golmund in the northwestern province of Qinghai, consists of a series of white tanks that compress air and cool it to -317 Fahrenheit (-194 degrees Celsius).

      >At this extremely low temperature, air turns into liquid. Once it is released, its volume expands by more than 750 times. This powerful expansion energy is harnessed to drive turbines and generate electricity.

      >The facility harvests energy from a connected 250,000-kilowatt photovoltaic farm that stretches out into the Gobi desert.

      …so is it the 250k solar array and/or did compressors get more efficient?

      can uber compressors make this viable on a residential (in the basement) level?

      ….because it also „provides“ air conditioning 😛

      It’s just compressed air storage, this isn’t new. Might be the biggest installation but let’s stop accepting IE’s clickbait headlines.

      Round trip efficiency for existing batteries is around 80%, pumped hydro storage is also around 80%. SMES is up around 95%.

      This compressed air system is claiming 55% round trip efficiency.

      Yes, this is an interesting project but it’s not problem solved. You need to produce far more energy using CAES to deliver the same peak time supply.

      It’s also worth mentioning that losses in transmission are about 5% per 1000km, so being located in the Gobi desert means that probably only half of the electricity produced by these solar panels and storage in this compressed air system will actually end up being able to be used by households.

      This might also serve as a LOX or neon production facility. If you’ve got the cryogenics anyway …
