Small Modules Spark Big Gains for US LNG Bunkering

Modular fueling systems drove a 62% surge in US LNG bunkering last year, proving that smaller infrastructure can deliver massive maritime results

16 Mar 2026

The expansion of the US maritime fuel market is increasingly defined by modular infrastructure, as port operators move away from the high capital requirements of traditional fixed terminals. A market report published on March 13, 2026, indicates that ISO-container and modular bunkering systems have become the fastest-growing segment in the liquefied natural gas (LNG) sector. These portable units allow smaller ports to establish refueling capabilities without the multi-year construction timelines typical of permanent facilities.

By deploying "capital-light" technology, secondary maritime corridors are now able to service dual-fuel vessels that were previously restricted to major hubs. This shift follows a significant period of growth for the industry; the global LNG bunkering market reached a valuation of $2bn in 2026. Data from Kpler shows that US bunkering volumes rose to approximately 578,000 tonnes in 2025, representing a 62% year-on-year increase.

Growth in the Americas, which saw total volumes jump 57% last year, has been anchored by the container shipping and cruise sectors. These industries have benefited from a competitive domestic gas supply and federal incentives aimed at reducing fleet emissions. The integration of digital monitoring and predictive analytics has further lowered operational risks, assisting ports in meeting safety and compliance standards for cryogenic fuels.

The global market is projected to reach $5.52bn by 2032, maintaining a compound annual growth rate of 17.79%. However, the pace of this expansion remains dependent on the development of a specialized workforce capable of managing complex cryogenic systems. As the "access gap" for alternative fuels narrows, the focus for US regulators and port authorities is shifting toward the standardization of these modular systems to ensure long-term network reliability.
