Alaska senator Dan Sullivan voiced support this week for the development of the proposed Alaska LNG liquefied natural gas project, citing the alignment between the plan's supporters and what he said are its strong competitive advantages, writes Caroline Evans.

"To me, the markets and the strategic competitive advantages with regard to an Alaska LNG project remain," Sullivan told reporters at CeraWeek in Houston.

The proposed $43 billion Alaska LNG mega-gas project being pursued by Alaska Gasline envisages a liquefaction facility at Nikiski producing up to 20 million tonnes per annum, a gas treatment plant on the North Slope and an 800-mile (1287-kilometre) pipeline to deliver gas for export and for customers in the state.
