SHELL - The global liquefied natural gas (LNG) market has continued to defy expectations of many market observers, with demand growing by 29 million tonnes to 293 million tonnes in 2017, according to Shell’s annual LNG Outlook. Such strong growth in demand is consistent with Shell’s first LNG Outlook, published in 2017. Based on current demand projections, Shell sees potential for a supply shortage developing in mid-2020s, unless new LNG production project commitments are made soon.
