CNG

CNG is an alternative to LNG and pipelines for marine transport of natural gas. CNG offers an economically attractive way to deliver commercial quantities of natural gas by ship to customers within 2,000 kilometers (1,200 miles). CNG is compressed and sometimes chilled (but not liquefied) at pressures of 2,000 to 3,000 psi (130 to 200 atm). CNG ships are in effect ‘floating pipelines.’ The on-shore facilities required for loading and off-loading from CNG transport are simple and inexpensive compared to LNG.
