With energy demand forecast to double in the first half of this century and conventional sources diminishing,the production of liquefied natural gas(LNG)continues to make an important contribution to meeting the energy challenge.The days of the so-called easy oil and gas are numbered.Increasingly,producers will need to access fossil fuel resources in more challenging environments and in more distant and remote locations.As the distances between resources and markets increase,LNG is vital to the security of energy supply.Not surprisingly,therefore,demand for LNG remains strong.In 2007,LNG accounted for about 7% of global gas consumption.Currently,LNG demand is growing at around 8%/yr to 10%/yr-four times the global annual growth rate of natural gas overall.
