Hexagon working on 700 BAR CNG containers!!

Currently, CNG is approved by the US DOT to be transported
at 250 BAR. A BAR is the same as an ATM, meaning 250 BAR is
like atmospheric pressure at sea level x250. So the gas is 250x more
dense than if it was not contained.

Hexagon Raufoss in Norway is working on large 700 BAR containers!
700 BAR= 10,000 psi. Remember the pressure created by frac-pumps
needed to fracture solid rock under 7,000'ft of overburden is ~15,000 psi.

700 BAR tanks are currently being tested in various countries for CNG fuel tanks
in vehicles (as opposed to payload tanks).

This could make LNG obsolete! Remember, by taking methane to
-260'F, at 1 BAR it becomes 600x concentrated. BUT-- LNG is super
expensive to create, require exotic/expensive containers, they leak
BY DESIGN, etc.

So if the industry can ship methane by using "ordinary" CNG at 10,000 psi,
it will be MORE concentrated as LNG, with presumably 1/2 to 1/10th the capital
costs.
