Vessels outfitted with dual-fuel LNG-burning engines are poised to have the lowest marine fuel expense heading into 2025 when the EU will tighten its marine EU emissions trading system (ETS) regulations and add a new regulation, "FuelEU", from 1 January 2025.
Considering both regulations, at current price levels, fossil LNG (also known as grey LNG) will be priced the cheapest compared with conventional marine fuels and other commonly considered alternative fuels such as biodiesel and methanol.
The EU's FuelEU maritime regulation will require ship operators traveling in, out and within EU territorial waters to gradually reduce their greenhouse gas (GHG) intensity on a lifecycle basis, starting with a 2pc reduction in 2025, 6pc in 2030 and so on until getting to an 80pc drop, compared with 2020 base year levels.
The FuelEU GHG intensity maximum is set at 85.69 grams of CO2-equivalent per MJ (gCO2e/MJ) from 2030 to 2034, dropping to 77.94 gCO2e/MJ in 2035. Vessel pools exceeding the FuelEU's limits will be fined €2,400/t ($2,675/t) ofvery low-sulphur fuel oil (VLFSO) energy equivalent. GHG emissions from grey LNG vary depending on the type of marine engine used to burn the LNG, but ranges from about 76.3-92.3 gCO2e/MJ, according to non-governmental environmental lobby group Transport & Environment. This makes a number of LNG-burning, ocean-going vessels compliant with FuelEU regulation through 2034.
The EU's ETS for marine shipping commenced this year and requires that ship operators pay for 40pc of their GHG generated on voyages within, in and out of the EU. Next year, the EU ETS emissions limit will increase to 70pc. Even with the added 70pc CO2 emissions cost, US Gulf coast grey LNG was assessed at $639/t VLSFOe, compared with the second cheapest VLSFO at $689/t, B30 biodiesel at $922/t and grey methanol at $931/t VLSFOe average from 1-18 September (see chart).
"In 2025, we expect [US natural gas] prices to rise as [US] LNG exports increase while domestic consumption and production remain relatively flat for much of the year," says the US Energy Information Administration. "We forecast the Henry Hub price to average around $2.20/million British thermal units (mmBtu) in 2024 and $3.10/mmBtu in 2025."
Provided that prices of biodiesel and methanol remain relatively flat, the projected EIA US 2025 LNG price gains would not affect LNG's price ranking, keeping it the cheapest alternative marine fuel option for ship owners traveling between the US Gulf coast and Europe.
LNG for bunkering global consumption from vessels 5,000 gross tonnes and over reached 12.9mn t in 2023, according to the International Maritime Organization (IMO), up from 11mn t in 2022 and 12.6mn t in 2021. The maritime port authority of Singapore reported 111,000t of LNG bunker sales and the port authorities of Rotterdam and Antwerp reported 319,000t in 2023 from all size vessels.
Among vessels 5,000 gross tonnes and over, LNG carriers accounted for 89pc of LNG bunker demand globally, followed by container ships at 3.6pc, according to the IMO. The large gap between LNG global and LNG Singapore, Rotterdam, and Antwerp bunker demand, is likely the result of most of the demand taking place at the biggest LNG export locations where LNG carriers call, such as the US Gulf coast, Qatar, Australia, Russia and Malaysia.
