Optimal conditions for storage and bulk transport of natural gas were defined in the 1960’s by H. C. Secord. Those optimal conditions were explored and confirmed through full-scale, USCG approved shipboard testing by R. J. Broeker and Columbia Gas System Service Corp. over 50 years ago.

A massive R&D program by ExxonMobil in the 1990’s and 2000’s re-confirmed the advantages of liquefying natural gas at temperatures well above traditional LNG by applying modest containment pressure. A “Pressurized LNG (PLNG)” facility is much simpler and less than half the size, requiring only about half as much energy as conventional LNG while producing a fluid nearly as dense (ref. Bowen et al, GasTech 2005). The reduced size, cost and complexity of PLNG plants makes it much more practical and safer to install them on barges than traditional LNG plants.

Now, ezNG Solutions offers a practical tank technology for storing traditional LNG or PLNG as well as gas handling technology for injecting natural gas fluids into and extracting them from containment. The ezNG® cells can be used individually or in assemblies that efficiently fill constrained storage spaces.

Alternatively, ezNG’s cellular array tanks made of low carbon steels can be used for highly efficient shipping of very large volumes of Liquefied CO2 (LCO2) for remote CCS / CCUS.
