By 2020, 18 LNG cargoes will load daily to satisfy 50 billion cubic feet per day of anticipated demand, based on current growth forecasts.

Martin Houston, co-founder of US liquefaction company Tellurian, said this means buyers are going to be able to bid for those 18 cargoes on a daily basis.

"Are we moving to a place where spot or the market will decide on [LNG] price, doing away with only long-term contracts?” he asked.
