Alternatively, LNG bunker fueling vessels used to fuel cruise liners and container ships typically hold 4,000 to 20,000 cubic meters (1 million to 5 million gallons). Elba Island will produce approximately 10,000 cubic meters (2.5 million gallons) per day of LNG and Shell may use some or all of that production to satisfy US LNG marine fuel demand. Shell has announced they will have a 4,000-cubic-meter (1 million gallon) LNG bunker fueling vessel operating on the US southeast coast, but it has not said where the needed LNG would be sourced.
