Hydrogen Bunkering Methods

Four approaches to refueling hydrogen-powered vessels—from fixed installations to innovative container swapping systems

Maritime hydrogen bunkering remains in its infancy, with infrastructure developing alongside the first generation of hydrogen-powered vessels. Unlike conventional marine fuels with established global supply chains, hydrogen bunkering requires purpose-built solutions tailored to the fuel’s unique physical properties—whether stored as compressed gas at 350–700 bar or as cryogenic liquid at -253°C.

Four distinct bunkering approaches have emerged, each offering different trade-offs between infrastructure investment, operational flexibility, and transfer efficiency. The optimal choice depends on vessel type, route patterns, and the maturity of hydrogen supply at specific ports.

Four distinct approaches to maritime hydrogen bunkering serve different operational requirements and infrastructure availability.

Bunkering Methods at a Glance

Method	H₂ Form	Location Flexibility	Transfer Speed	Infrastructure Cost	Best Suited For
Fixed Shore Installation	CH₂ LH₂	Low—single port	Fastest	High	Ferries, regular routes
Truck-to-Ship	CH₂ LH₂	High—any accessible quay	Moderate	Low	Multi-port operations, early adopters
Ship-to-Ship	LH₂	Very high—at anchor/offshore	Moderate–Fast	Medium–High	Deep-sea vessels, offshore operations
Container Swapping	CH₂ LH₂	Medium—crane-equipped ports	Very fast (swap only)	Medium	Inland shipping, fixed routes

Note: Transfer speeds and costs vary significantly based on specific equipment, pressure differentials, and local conditions. Values shown are general guidance.

Explore Each Method

[ 🏭 Fixed Shore Installation Permanent quayside bunkering stations offering highest throughput for vessels on regular routes.

• Fastest transfer rates
• Direct integration with H₂ production
• High infrastructure investment

Safety & Regulatory Framework

Hydrogen bunkering safety builds on decades of industrial hydrogen handling experience, adapted for the marine environment. International standards are evolving rapidly as operational experience accumulates.

Key Safety Considerations

Universal Requirements

• Hazardous area classification and ventilation
• Gas detection and emergency shutdown systems
• Grounding and bonding for static discharge
• Exclusion zones during transfer operations
• Trained personnel with hydrogen-specific certification

Key Standards: IGF Code (IMO), ISO 20519 (ship bunkering), SGMF guidelines, and classification society rules from DNV, Lloyd’s Register, and others provide the regulatory framework for hydrogen bunkering operations.
