Classification society Bureau Veritas (BV) on Monday (12 September) has awarded an Approval in Principle (AiP) to Gas and Heat (GH), a company specialising in the design, construction and integration of Liquefied Gas Handling Systems both for Marine and Onshore installations, for their flexible solution for the transport of liquified natural gas (LNG) and ammonia.

Through a thorough study, GH supported by the BV team demonstrated that IMO Type C cargo/fuel tanks made of austenitic steel with a special grade can transport both LNG and ammonia for sea-going and inland navigation.

Paillette Palaiologou, Vice President South East Europe, Black Sea & Adriatic Zone at Bureau Veritas Marine & Offshore, said: “While the shipping industry is facing many uncertainties, it is the role of class to support the industry in this period of change. I am proud of the work accomplished by both teams and the results are extremely positive for the industry. Providing different options will be key for industry stakeholders as they make decision. We look forward to collaborating with GH on new projects.”

Mauro Evangelisti, President of Gas and Heat SpA, said: "Innovation has always been and will remain our main focus. This study is part of the innovation journey the industry needs for a smart and sustainable transition to a greener future. We hope the use of this material will provide more cost-effective and safer components to the industry."

As part of their ambitions to develop innovative solutions to help the industry anticipate the next wave of alternative fuels, GH embarked on a study to identify possible options and develop solutions.

GH has used austenitic steel with a special grade for LNG containment since its Approval by Bureau Veritas in June 2022, as an “alternative material” with respect to IGC/IGF Code. The compatibility of this material with ammonia has been verified by a specific Stress Corrosion Cracking test performed by GH and then approved by Bureau Veritas in August 2022.

For this innovative material in the shipping world, twelve specimens were prepared for the tests in accordance with ISO 16540. ISO 16540 provides guidelines to evaluate the corrosion of metals and alloys by determining their resistance to stress corrosion cracking using the Four-Point Bend method. This methodology includes procedures for metals that have no distinct yield point in their stress-strain behavior as well as metals with a distinct yield point.

Throughout the test, the specimens were loaded as Four-Point-Bend (FPB) to the Specified Minimum Yield Strength of the base material. Tests were then performed in three different conditions: at ambient temperature, -20C, and -33C, in an environment of pure ammonia.

After the completion of all tests, each specimen was visually examined at x10 magnification by a stereoscopic microscope and subjected to fluorescent liquid penetrant examination to detect any visible surface crack. An additional tomographic scan was performed to ascertain that no inner crack was detected. The outcomes successfully demonstrated that cargo/fuel tanks made of austenitic steel can carry both LNG and ammonia, for seagoing and inland navigation.

BV was involved from the very earliest stages, validating the stress test methodology and reviewing each phase of the test.

“We confirmed that the applied methodology opens the way to design and build LNG/Ammonia tanks that comply with the international code for the construction and equipment of ships carrying liquefied gases in bulk (IGC Code) and the international code of safety for ship using gases or other low-flashpoint fuels (IGF Code), as well as applicable BV’s classification rules for seagoing and inland navigation,” said BV.

GH has already secured one contract which includes the supply of cargo tanks for inland navigation of LNG/ammonia and one for a seagoing LNG/ammonia fuel supply system.

Indonesia and HDF Energy partner to study hydrogen solutions for maritime decarbonisation

PT HDF Energy Indonesia, a subsidiary of French hydrogen infrastructure developer HDF Energy, recently signed a Memorandum of Understanding (MoU) with Indonesia’s Ministry of Transportation (MoT), state-owned electric utility PT PLN (Persero) and ferry operator PT ASDP Indonesia Ferry (Persero).

The agreement outlined a joint study to decarbonise Indonesia's maritime sector using locally produced green hydrogen. The study will be conducted in collaboration with, and co-funded by, the International Maritime Organization (IMO).

The MoU was signed during the Global Hydrogen Ecosystem Summit on April 15, 2025 in Indonesia.

The study will focus on Eastern Indonesia, a region with plenty of sun and home to many of ASDP's strategic ferry routes. HDF Energy is currently developing 23 Renewstable® hydrogen power plants in the region. These facilities combine a solar park with substantial on-site energy storage in the form of green hydrogen to provide non-intermittent, stable and 100% clean electricity to the grid, day and night.

By generating surplus green hydrogen at a competitive marginal cost, Renewstable® plants also pave the way for the supply of green hydrogen to decarbonise maritime transport. The hydrogen produced will be used to power the high-power fuel cells developed and manufactured by HDF Energy in France, a modular, reliable solution tailored to the conversion of maritime fleets.

With this project, HDF Energy is deploying an integrated approach: producing competitive green hydrogen locally and offering a zero-emission maritime vessels' propulsion solution based on its fuel cells.

ASDP, which operates one of the world's largest ferry networks, plays a critical role in connecting Indonesia's remote islands. As a key player in the maritime sector's energy transition, the company will contribute to the study to identify opportunities for converting its fleet and port infrastructures. The aim is to replace traditional diesel engines with solutions based on green hydrogen and renewable electricity, in order to significantly reduce emissions.

PLN has already taken a proactive role in launching hydrogen pilot projects across the country. The company previously signed an MoU with HDF Energy to accelerate the deployment of Renewstable® hydrogen power plants as a green alternative to diesel-based power — a collaboration representing potential investments of up to USD 2.3 billion, supported by international development institutions including the U.S. International Development Finance Corporation (DFC).

On the same occasion, HDF also signed an MoU with PT Pelayaran Bahtera Adhiguna (PT BAg), a national shipping company specialising in sea transportation services for primary energy distribution across Indonesia. The partnership reflects a joint commitment to assessing hydrogen as a clean alternative to power auxiliary systems on large vessels.

Mathieu Geze, HDF Energy's Director for APAC and President Director of PT HDF Energy Indonesia, stated: “We are proud to reaffirm our commitment to a Net Zero emission future through this strategic collaboration. Working together with PLN, ASDP, the Ministry of Transportation, and with PT Bag, we aim to place Indonesia at the forefront of green hydrogen innovation in the Asia-Pacific. Our fuel cells represent a decisive step forward in the decarbonization of maritime transport in the Indonesian archipelago, as well as a formidable showcase for French innovation on the international stage.”

On a regional scale, this partnership in Indonesia is part of HDF Energy's development drive in Southeast Asia.

On 11 April, in the Philippines, HDF signed a MoU with the Department of Transportation to harness green hydrogen—produced by HDF's Renewstable® power plants currently under development—to power the next generation of hydrogen-fuelled maritime vessels.

The following day in Vietnam, HDF entered into a strategic partnership with ACST, an organisation affiliated with the Ministry of Construction, to advance green hydrogen solutions, including the retrofitting of diesel ferries with HDF's hydrogen fuel cells.

An International Maritime Organization (IMO) proposal for ship owners who exceed emissions reduction targets to earn surplus credits will play a key role in biofuel bunkering options going forward.

22 April 2025

The price of these credits will help determine whether B30 or B100 becomes the preferred bio-bunker fuel for vessels not powered by LNG or methanol. It will also influence whether biofuel adoption is accelerated or delayed beyond 2032.

At the conclusion of its meeting earlier this month the IMO proposed a dual-incentive mechanism to curb marine GHG emissions starting in 2028. The system combines penalties for non-compliance with financial incentives for over-compliance, aiming to shift ship owner behavior through both "stick" and "carrot" measures. As the "carrot", ship owners whose emissions fall below the IMO's stricter compliance target will receive surplus credits, which can be traded on the open market. The "stick" will introduce a two-tier penalty system. If emissions fall between the base and direct GHG emissions tiers, vessel operators will pay a fixed penalty of $100/t CO2-equivalent. Ship owners whose emissions exceed the looser, tier 2, base target will incur a penalty of $380/t CO2e. Both tiers tighten annually through 2035.

The overcompliance credits will be traded on the open market. It is unlikely that they will exceed the cost of the tier 2 penalty of $380/t CO2e. Argus modeled two surplus credit price scenarios — $70/t and $250/t CO2e — to assess their impact on bunker fuel economics. Assessments from 10-17 April showed Singapore very low-sulphur fuel oil (VLSFO) at $481/t, Singapore B30 at $740/t, and Chinese used cooking oil methyl ester (Ucome), or B100, at $1,143/t (see charts).

If the outright prices remain flat, in both scenarios, VLSFO would incur tier 1 and tier 2 penalties, raising its effective cost to around $563/t in 2028. B30 in both scenarios would receive credits putting its price at $653/t and $715/t respectively. In the high surplus credit scenario, B100 would earn roughly $580/t in credits, bringing its net cost to about $563/t, on par with VLSFO, and more competitive than B30. In the low surplus credit scenario, B100 would earn just $162/t in credits, lowering its cost to approximately $980/t, well above VLSFO.

At these spot prices, and $250/t CO2e surplus credit, B100 would remain the cheapest fuel option through 2035. At $70/t CO2e surplus credit, B30 becomes cost-competitive with VLSFO only after 2032. Ultimately, the market value of IMO over-compliance credits will be a major factor in determining the timing and extent of global biofuel adoption in the marine sector.
