There are claims or at least assumptions that: "upon approaching "critical point" pure gases become super compressible. You could compress them many times without pressure increase and store like this if you maintain exact temperature and pressure needed. It opens possibility to superdense gas storage. Impurities tend to destroy this state by triggering convertion to a gas phase. If critical point temperature is exceeded this state is destroyed."

Methane critical point is -82 C at 45 atm. Does it open a new possibilities to store methane or natural gas at liquid form? Natural gas isn't pure gas, does it have a critical point? Could some additives extend temperature brackets of a critical point?
