BillHustonBlog: 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.
