Seaside LNG

What Seaside LNG does

Seaside LNG is a Houston-headquartered private LNG production and bunkering logistics platform operating the only fully integrated domestic LNG supply chain in North America — combining shoreside liquefaction, LNG storage, and Jones Act-compliant maritime bunkering infrastructure. The company is structured around two principal assets: a 50/50 joint venture with Pivotal LNG (BHE GT&S, a Berkshire Hathaway Energy subsidiary) for the JAX LNG facility in Jacksonville, Florida — a small-scale LNG liquefaction plant with 360,000 gallons per day of production capacity and 4 million gallons of storage — and Polaris New Energy LLC, a wholly owned subsidiary that operates the largest fleet of Jones Act-compliant LNG bunker barges in the United States (Clean Canaveral and Clean Everglades, each 5,500 cbm; Clean Jacksonville, 2,200 cbm; totaling approximately 13,200 cbm of bunker capacity).

The company's service portfolio spans LNG and BioLNG bunkering operations (including ship-to-ship fueling), supply and distribution, energy management (hedging and supply agreements), project planning for LNG adoption, and cooldowns/commissioning support for LNG-fueled vessels. Operations are conducted from Houston (corporate headquarters) and Jacksonville (operations hub), with active service at Jacksonville, Port Canaveral, Galveston, Baltimore, and Pacific Northwest ports, and development underway at multiple additional U.S. ports and Bahamas/Puerto Rico.

Seaside LNG generates revenue through long-term enterprise contracts with major ocean-going vessel operators across container shipping (CMA CGM, TOTE Maritime), cruise lines (Carnival Corporation, Royal Caribbean, Disney Cruise Line), and cargo carriers (Pasha Hawaii). Pricing is quote-driven and confidential, structured around per-vessel-call LNG bunker transfers and multi-year fuel supply agreements. The company is sponsored by Houston-based energy infrastructure investor Arroyo Investors and was founded operationally in 2015 with the establishment of JAX LNG.

Revenue model

1. LNG Bunkering Services: Seaside LNG charges vessel operators a per-metric-ton or per-gallon fee for physical LNG fuel transfer (bunkering) services at U.S. ports, particularly Jacksonville, Baltimore, and the Pacific Northwest. Revenue is transactional per vessel call, with recurring revenue driven by scheduled liner service contracts.
2. LNG Fuel Supply (via JAX LNG JV): Seaside LNG sells LNG as a fuel commodity to maritime customers through its Pivotal LNG joint venture (JAX LNG), generating supply contract revenue from long-term LNG sale and purchase agreements with shipping lines.

Core offering

Seaside LNG operates an integrated LNG production and bunkering logistics platform, producing and delivering LNG fuel to maritime operators at major U.S. ports. The company owns the largest fleet of Jones Act-compliant LNG bunker barges in the United States (Clean Canaveral, Clean Everglades, Clean Jacksonville) and operates the JAX LNG liquefaction and distribution facility in Jacksonville, Florida through a 50/50 joint venture with Pivotal LNG. Seaside delivers LNG as a cleaner-burning marine fuel to container lines, cruise operators, and cargo vessels under multi-year enterprise contracts.

Product overview

Seaside LNG operates as an integrated LNG production and bunkering logistics platform—the only company with integrated shoreside liquefaction, LNG storage, and Jones Act-compliant bunkering capabilities in North America. The platform centers on JAX LNG (a 50/50 joint venture with Pivotal LNG), the first small-scale shoreside LNG facility in the U.S., which produces 360,000 gallons per day with 4 million gallons of storage. The bunkering operations are conducted through subsidiary Polaris New Energy, which operates the largest fleet of Jones Act-compliant LNG barges in North America, including Clean Canaveral (5,500 cbm), Clean Everglades (5,500 cbm), and Clean Jacksonville (2,200 cbm). The portfolio also includes complementary services such as supply and distribution, energy management (risk management, hedging, supply agreements), project planning for LNG adoption, cooldowns and commissioning support, and regulatory consulting.

Direct peers

• Titan LNG: Titan LNG is a dedicated small-scale LNG bunker supplier operating across Northwest Europe with truck-to-ship and barge solutions. It is directly comparable to Seaside LNG in pure-play LNG bunkering focus, though it does not have a Jones Act-constrained U.S. footprint.
• Gasum: Gasum is a Nordic LNG distribution and bunkering company operating bunker barges in Northern Europe. It is a directly comparable pure-play LNG bunker operator with similar barge-based delivery model and downstream customer profile (cruise, cargo, ferry).
• Bunker Holding A/S: Bunker Holding is one of the world's largest independent marine fuel suppliers, with growing LNG bunker trading and physical supply operations globally. It is comparable as a marine bunker competitor with overlapping bunker fuel customer base and similar enterprise sales motion.
• Peninsula Petroleum: Peninsula is one of the largest independent physical marine fuel suppliers globally, increasingly active in alternative fuels including LNG bunker trading and delivery. It is a comparable marine bunker competitor serving a similar portfolio of cruise, container, and bulk customers.

Others

• GAC Bunker Fuels: GAC is a global marine fuel logistics and trading company and a documented channel partner of Seaside LNG. It is comparable as an enabling/distribution participant in the LNG bunker supply chain rather than a direct competitor.
• Fincantieri S.p.A. Fincantieri's Bay Shipbuilding division built Clean Canaveral and Clean Everglades for Seaside LNG. It is an adjacent participant as the leading builder of Jones Act-compliant LNG bunker barges and an enabling infrastructure supplier rather than a competitor.

Regional players

• Crowley Maritime Corporation: Crowley is a major U.S.-flagged Jones Act vessel operator with extensive LNG and energy logistics capabilities in the Caribbean/Puerto Rico trade. It overlaps with Seaside LNG in the Jones Act domestic trade market and shares key customers (e.g., Puerto Rico container routes).

Broad incumbents

• Shell Marine Products (Shell plc): Shell is the world's largest marine fuel supplier and a leading LNG bunker player operating at Rotterdam, Singapore, and U.S. Gulf ports. It is the dominant global LNG bunkering incumbent that Seaside LNG competes against for international and select U.S. opportunities.
• TotalEnergies Marine Fuels: TotalEnergies is a top-tier global marine fuel supplier with growing LNG bunkering operations in Europe and Asia. It is a comparable broad incumbent in the same LNG bunker fuel category, though it does not operate Jones Act-compliant U.S. domestic assets.

Emerging players
