Japan Engine Corporation (J-ENG) on Friday (18 September) said it has completed land-based testing of the world’s first hydrogen-fuelled engine for large commercial vessels, the 6UEC35LSGH.

During factory testing, the engine achieved a hydrogen co-firing rate of at least 95%, reducing GHG emissions by more than 95% compared with conventional heavy-fuel-oil engines.

By adopting a high-pressure direct injection system, which injects fuel directly into the cylinder at high pressure, J-ENG said the engine achieves stable hydrogen combustion. 

Safety measures were also implemented, including a robust structure to prevent hydrogen leakage and double-walled piping for hydrogen supply lines. 

“Approval testing was conducted in the presence of ClassNK and was completed successfully,” the company said. 

The engine will be installed on a 17,500 DWT multipurpose vessel to be built by Onomichi Dockyard for Mitsui O.S.K. Lines and MOL Drybulk.

Hydrogen fuel will be supplied to the engine through a marine hydrogen fuel system, consisting of marine hydrogen fuel tanks and a fuel supply system, developed and manufactured by Kawasaki Heavy Industries.

In addition, Nippon Kaiji Kyokai (ClassNK) will conduct safety assessments throughout each stage of the engine’s development and the vessel’s design, construction and operation.

The vessel will then undergo sea trials before onboard demonstration testing begins in April 2028. 

Kawasaki will also develop and manufacture bunkering equipment for supplying liquefied hydrogen to vessels. 

“The demonstration will further evaluate the engine’s durability and performance under actual operating conditions,” J-ENG added.

Classification society DNV on Monday (21 September) highlighted progress made on several regulatory and technical matters at the 12th session of the IMO Sub-Committee on Carriage of Cargoes and Containers (CCC 12), held from 14 to 18 September. 

This includes alternative fuels, cargo securing, onboard carbon capture systems, and battery carriage: 

Amendments to the IGF Code and development of guidelines for alternative fuels and related technologies

Methyl/ethyl alcohols

CCC 12 finalized the revision of the Interim Guidelines for the Safety of Ships Using Methyl/Ethyl Alcohol as Fuel (MSC.1/Circ.1621). The amendments revise all sections of the existing guidelines, taking into account experience gained to date.

The revised guidelines:

• provide more flexibility in fuel tank placement and leakage-handling arrangements;
• introduce a new concept for ventilation of fuel spaces;
• expand guidance on the design of bunkering stations and fire extinguishing; and
• add new guidance on bunkering operations and personal protective equipment.

Low-flashpoint oil fuels

CCC 12 continued work on the interim guidelines for ships using low-flashpoint oil fuels (fuel with a flashpoint between 52°C and 60°C). It was agreed not to develop detailed provisions for the “temperature-controlled engine room concept” but focus on a safety concept more aligned with the existing guidelines under the IGF code, however with major simplifications of the safety barriers. Work on the interim guidelines will continue in a Correspondence Group aiming for finalization at CCC 13 in 2027.  

Fuel cell power installations and IGF Code amendments

The revision of the Interim Guidelines for the Safety of Ships Using Fuel Cell Power Installations (MSC.1/Circ.1647), and other proposals for amendments to the IGF Code were not discussed in detail, but work will continue in a Correspondence Group reporting to CCC 13 in 2027.  

Development of a safety regulatory framework to support the reduction of GHG emissions from ships using new technologies and alternative fuels

Onboard carbon capture and storage (OCCS)

CCC 12 started the discussion to develop guidelines for the safety of ships fitted with OCCS. The guidelines should contain a technology-neutral main body for common ship-level requirements, while technology-specific safety requirements will be placed in individual annexes. Work on the guidelines will continue in a Correspondence Group reporting to CCC 13 in 2027. The guidelines are expected to be finalized in 2028.

Once a week, bunker intelligence platform ENGINE will publish a snapshot of biofuel bunker prices in Europe, Fujairah and Singapore. The following is the latest snapshot:

• B100 price surges in Rotterdam this week
• Gibraltar’s B30-VLSFO price drops sharply
• Singapore’s bio-blended bunker volumes rose sharply

Europe

Rotterdam’s B30-VLSFO (POMEME) price has dropped $17/mt in the past week, most probably pressured by a $24/mt drop in the Dutch port’s conventional VLSFO price during the same period.

Rotterdam’s B30-LSMGO (POMEME) price has gained by $17/mt to $1,476/mt, which has been similar to a $19/mt gain in the port’s conventional LSMGO price.

B100 has been priced at $1,418/mt in Rotterdam today, a sharp $209/mt increase compared to last week.

Prima Markets’ POMEME barge price, which is an indicator of feedstock sourcing costs, has gone up by $35/mt to $2,059/mt.

Dutch suppliers can generate ZRE A tickets for selling low carbon fuels, which can be traded with other suppliers. The price of these tickets has dropped from €200/mtCO2e ($230/mtCO2e) last Friday to €190/mtCO2e ($218/mtCO2e) on Thursday this week.

Gibraltar’s B30-VLSFO (UCOME) price has slumped $166/mt lower in the past week. The port’s conventional VLSFO price has remained largely unchanged during this period.

This has cut the port’s B30-VLSFO price premium over conventional VLSFO by $172/mt in a single week to $250/mt.

Lisbon’s B30-VLSFO price has dropped $107/mt during the week. It has flipped to a modest $9/mt premium over Gibraltar’s B30-VLSFO price, coming from a $50/mt discount last Friday.

Lisbon’s B30-LSMGO price has slumped $115/mt to $1,600/mt, while the B100 price in the Portuguese port has plunged $215/mt lower to $1,665/mt.

Asia

Singapore’s B30-VLSFO (UCOME) price has dropped $56/mt since last Friday, while the port’s conventional VLSFO price has gained only $5/mt over the same period.

This has narrowed the port’s B30-VLSFO price premium by $61/mt in a single week.

Data this week showed Singapore’s bio-blended bunker sales rose by 48% in August to 57,000 mt, which was the highest monthly volume since April.

B30-VLSFO is priced at $1,015/mt in Hong Kong, which is a $35/mt price discount to Singapore.

Hong Kong’s B30-VLSFO price is at a $109/mt premium over its conventional VLSFO price.
