Compressed natural gas (1500 to 2500 psi and 0 to – 40 F). There are 2 technologies for CNG transport: (a) The Cran & Stennings approach; (b) The Enersea approach. CNG is best suitable for voyage distances of up to 2500 miles. Cost of CNG transport: $1.86-$2.43/Mscf (depending on pressure and temperature); Published Cost of LNG transport: $1.89/Mscf. As the distance decreases CNG becomes more attractive than LNG
