Maritime Technologies Forum Unveils Hydrogen Bunkering Guidelines

The Maritime Technologies Forum (MTF), which includes flag states and classification societies, has released a detailed report outlining safety guidelines and important considerations for developing systems to bunker liquefied hydrogen. This effort supports the International Maritime Organization’s (IMO) goal of achieving zero greenhouse gas emissions from ships by 2050.

Hydrogen is seen as a promising zero-emission fuel for ships, but the MTF report points out the specific challenges of using hydrogen, especially in its liquefied form, as a marine fuel. Key findings from the report include:

• Unique Properties of Hydrogen: The extremely low temperature of liquefied hydrogen requires special bunkering arrangements. Experience with LNG doesn’t directly apply to hydrogen.

• Complex Bunkering Process: Handling liquefied hydrogen requires a piping system free of nitrogen to prevent freezing and blockages, making it more complex than LNG bunkering.

• Material and Insulation: Hydrogen systems need different materials and better insulation compared to other fuels.

• Customized Procedures: Special procedures for hydrogen bunkering are necessary, which may include more automation to handle the complexities involved.

• Training and Certification: Due to the increased complexity, crew members will need specialized training and certification, highlighting the need for expertise in hydrogen bunkering.

• Enhanced Safety Protocols: Safety systems must be updated to manage the extra risks of using liquefied hydrogen, in line with the MTF’s guidelines on safety management for alternative fuels on ships.

These guidelines are a vital step toward making hydrogen a practical and sustainable fuel for maritime use, emphasizing safety, training, and the need for customized equipment.
