A consortium of 26 leading companies and associations, led by DNV, has launched the “Handbook for Hydrogen-fuelled Vessels” to address the uncertainties surrounding hydrogen as ship fuel. The MarHySafe joint development project (JDP) aims to create a knowledge base for safe hydrogen operations in shipping:

Green hydrogen could play a crucial role in the maritime industry’s journey towards decarbonization. Many in shipping recognize hydrogen’s potential as a fuel, but the barriers to realizing this potential are substantial. Led by DNV, a consortium of 26 partners and observers have come together in the MarHySafe JDP to examine these challenges. The Handbook for Hydrogen-fuelled Vessels offers a roadmap towards safe hydrogen operations using proton exchange membrane fuel cells (PEMFC). It details how to navigate the complex requirements for design and construction, and it covers the most important aspects of hydrogen operations, such as safety and risk mitigation, engineering details for hydrogen systems and implementation phases for maritime applications.

“Green hydrogen is one of the zero carbon fuels that could be vital to meeting the IMO GHG goals, but as with other new fuels, there are still significant challenges regarding its safe and widespread implementation,” said Knut Ørbeck-Nilssen, CEO DNV Maritime. “We are fortunate to be working with companies that are really ahead of the curve in terms of hydrogen operations. Having such esteemed partners and observers on board this project makes the insights gleaned all the more valuable. Furthermore, it shows how the shipping industry can pool its collective expertise and to tackle these crucial issues. We work best when we work together – the handbook is testament to this.”

Some of the main challenges for hydrogen operations in shipping include the current regulatory framework, which is open to interpretation by different stakeholders, existing knowledge gaps on the safe handling, storing and bunkering of hydrogen, as well as the unique properties of hydrogen that make it challenging to work with.

“This handbook provides a comprehensive overview of what companies need to consider with a hydrogen-fuelled vessel, as well as areas that require further investigation and testing before this technology can be taken up on a larger scale,” said Nathaniel Frithiof, Senior Consultant, Environment Advisory at DNV Maritime and Project Manager for Phase II of MarHySafe. “But as MarHySafe progresses, we are working to ensure that the Handbook is much more than a static document, rather a knowledge hub that will be continually updated and will provide a basis for the future development of hydrogen rules.”

In the summer, the MarHySafe JDP enters into Phase II. This will include pre-calculated risk assessments, experimental testing, as well as more work on hydrogen bunkering and input towards standardization. Alongside this, the Handbook for Hydrogen-fuelled Vessels will be updated continually as the project progresses to reflect the current level of expertise in the industry.

The MarHySafe Phase 1 project partners include: the Norwegian Maritime Authority (NMA), the Norwegian Defence Materiel Agency (Naval Systems, NDMA), Equinor, Shell, Air Liquide, Linde, Kawasaki, Chart Industries, Parker, UMOE Advanced Composites, Hexagon Purus, Fincantieri, Feadship, HySeas Energy, Ballard, Cummins (previously Hydrogenics), Corvus Energy, A.V.Tchouvelev & Associates, Vancouver Fraser Port Authority, Redrock, Hydrogen Technology & Energy Corporation (HTEC), Memorial University, and DNV. The Norwegian Public Roads Administration (NPRA), the Standards Council of Canada, and the Norwegian Directorate for Civil Protection (DSB) were observers in MarHySafe Phase 1.

BHP and GCMD trial multi-feedstock B100 bio bunker fuel on bulk carrier

BHP and the Global Centre for Maritime Decarbonisation (GCMD) on Wednesday (3 June) said they have blended biofuels from two distinct feedstocks—used cooking oil and waste animal fats —and introduced the lower-emissions marine fuel into a BHP-chartered bulk carrier as part of a pilot project.

The bio-blend in the BHP and GCMD pilot is being used on a BHP-chartered bulk carrier Berge Lyngor, owned and operated by Berge Bulk, transporting BHP iron ore from Western Australia to China. When run on bio-blend, the vessel has the potential to reduce well-to-wake greenhouse gas emissions by approximately 79 per cent per voyage compared to sailing on very low sulphur fuel oil (VLSFO).

The vessel bunkered in Singapore in early May with a B100 bio-blend comprising 50 percent tallow-derived biodiesel, sourced and supplied by HAMR Energy, and 50 per cent used cooking oil (UCOME) supplied by Mitsui & Co Energy Trading Singapore (METS).

Mitsui also blended the fuel and Dan-Bunkering coordinated and executed the bunkering operation, which was performed by Global Energy’s barge MT Maple.

The BHP and GCMD pilot will assess how biofuels from multiple feedstocks can be blended, handled, and introduced under real-world operating conditions using existing used cooking oil bunkering infrastructure.

At the same time, insights from this pilot will help identify solutions to challenges related to fuel quality, handling, traceability, and onboard vessel performance.

Biofuels for global shipping today rely heavily on used cooking oil – a feedstock whose availability is approaching its projected limits. Biofuel from waste animal fats presents a promising option to expand the supply of lower-emissions marine fuels.

The outcomes of the pilot are expected to shed light on the practical steps to integrate biofuel blends from different feedstocks into existing supply chains. The diversity of biofuels will provide shipowners and operators with greater flexibility to optimise fuel procurement based on cost, availability, and lifecycle emissions performance.

Biofuels derived from different feedstocks can exhibit varying properties that may impact operations, including potential corrosion from oxidation, fuel system clogging caused by wax formation, which this pilot aims to assess.

The pilot will trace and verify the biofuel blend’s integrity aimed at bolstering confidence in emissions reductions reporting. The pilot will also provide insights into how robust tracing can support future marine fuel supply chains where biofuels from multiple feedstocks with varying lifecycle greenhouse gas emissions footprints are blended together.

This project is co-funded by the Maritime and Port Authority of Singapore under the Maritime Innovation and Technology Fund (MINT).

NYK starts one-year B100 bio bunker fuel trial on car carrier

Japanese shipping firm NYK on Tuesday (2 June) said it has commenced a one-year long-term trial involving the continuous use of 100% biofuel (B100) on an NYK-operated car carrier. 

In this trial, NYK will operate a car carrier continuously on B100 for one year to evaluate the impact on engines, fuel supply systems, and operational practices. High-purity biofuels such as B100 are known to be susceptible to degradation from oxygen, light, and heat, raising concerns about the stability of such fuels during long-term use.

In this trial, the biofuel primarily comprises FAME (Fatty Acid Methyl Ester) derived from used cooking oil and similar feedstocks.

The initiative is designed to evaluate the fuel’s effects on the vessel’s equipment and verify operational safety under real-world conditions. 

Through this effort, NYK seeks to accumulate technical expertise that will support the broader use of high-purity biofuels and further accelerate efforts to reduce greenhouse gas (GHG) emissions.

NYK has been advancing the use of biofuels through various initiatives. In 2024, the company conducted a trial using biofuel blend B24 and subsequently expanded practical usage to B30. However, the company said there remains limited global experience with the long-term continuous use of B100.

“By collecting long-term operational data through this trial, NYK aims to accumulate valuable technical insights to support both the safe operation of vessels and the wider adoption of high-purity biofuels,” it said.
