Demand for liquefied natural gas (LNG) as a marine fuel is projected to at least double by 2030 as abundant global supply and tougher emission norms accelerate fleet conversions.

Singapore led LNG bunkering volumes in Q3 2025, followed by China and the Netherlands. According to Rystad Energy, global LNG bunkering may exceed 4 million tonnes by end-2025 and double by 2030.

Ship certifier DNV estimates the number of LNG-ready vessels will rise from 781 today to over 1,400 by 2030.
