The American Clean Skies Foundation released a landmark study that highlights how the maritime industry could switch to operating vessels on natural gas and benefit from low prices and low emissions.
The study offers the first in-depth look at the challenges and prospects for converting U.S.-flagged marine vessels to liquefied natural gas (LNG). Low natural gas prices – coupled with rising oil prices – have opened up a significant gap between LNG and traditional marine fuels.
On the environmental front, the maritime industry is facing federal regulations to reduce emissions of nitrogen oxide, particulate matter and sulfur dioxide, which will require switching to ultra-low sulfur diesel. Low in sulfur, LNG can be used to comply with the regulations. Norwegian shipping fleets have been successfully operating on LNG for years.
The report points to two obstacles to fuel switching: the high cost of vessel conversion and the lack of LNG infrastructure, especially at marine ports. The most promising sites are where LNG liquefaction/storage facilities are located close to ports.
The most promising and economical conversions would be large towing tugs, medium-to-large car and passenger ferries, and Great Lakes bulk carriers.
