The following article was published by Cristina Saenz de Santa Maria, Regional Manager South East Asia, Pacific & India, DNV Maritime through the social media platform LinkedIn on Monday (10 January):

The recent COP26 summit in Glasgow made it crystal clear that shipping is heading for carbon zero, but the route there is far from it. The grand challenge of our time remains: how to fuel the maritime industry’s transition to a carbon neutral future?

This is a question Singapore has prioritized as part of its green transition.

Why?

It is the world’s largest bunkering hub. It imports all the gas it needs to power households and the economy. And the strategically located island state has always been looking into the future to keep a leading edge.

In my view, Singapore is in a very good position to play a key role in the decarbonization of the global maritime industry. An important step was the establishment of the Global Centre for Maritime Decarbonisation (GCMD), in which DNV readily agreed to become a founding partner.

The Centre and its partners have now started to explore a portfolio of alternative fuels and strategies that will hopefully enable shipping globally to significantly reduce its greenhouse gas (GHG) emissions.

New fuels on the horizon include sustainable biofuels, biodiesel, bio-LNG, methanol, hydrogen, and ammonia, amongst others.

However, they “must be greener than the incumbent fuels, have a lower carbon life cycle, otherwise it would be a waste of resources to venture into such investments, as it will not reduce the overall carbon/GHG burden on the environment,” rightly notes GCMD Chief Technology Officer Dr Sanjay Kuttan.

GCMD picked ammonia as the first fuel to take a closer look into and commissioned a technical evaluation to define the safety and operational envelopes for ammonia bunkering in Singapore.

So, we must ask ourselves, how viable is ammonia and is it safe enough for widespread use as a marine fuel in Singapore, or anywhere, for that matter?

From our own studies and from pilot programmes conducted in Europe in particular, ammonia comes clean as an ideal marine fuel, as it provides better energy performance than hydrogen and it’s on a par with LNG.

Not only does ammonia burn CO₂-free, like hydrogen, but it has a higher energy density and is easier to store and transport than hydrogen, as it doesn’t require cryogenic – or ultra-cool – storage.

But what about green ammonia? How is it produced and where does it come from?

We know that it is currently going through marine fuel trials in Europe and Japan, and we see that one of the best Asia Pacific sources for green ammonia (and/or green hydrogen) could be Australia, as it is already a major supplier of LNG.

Green ammonia can be produced from green hydrogen, a well-established renewable energy source. Australia already has plans for major green hydrogen plants. In addition, ammonia is widely used there in agriculture, most commonly as a fertiliser.

We’re encouraged to see that the International Energy Agency (IEA) rates green ammonia highly as a shipping fuel for the future. In its Net Zero Emissions Scenario, IEA shows that green ammonia could meet around 45% of global shipping fuel demand by 2050. It also sees it as the lowest cost option as an alternative fuel for the future.

Another advantage for liquid fuels like hydrogen or ammonia is that they can safely be used alongside LNG during the transition phase. We also know that ship engines are being designed in Europe to accommodate ammonia, as an onboard fuel, alongside LNG.

Trials in Norway, for example, have shown that ammonia can be safely deployed even in passenger vessels and the researchers clearly could not identify any “incomprehensible technical or safety barriers”.

The decarbonization process for the global maritime industry is not going to be easy. I know there are challenges, but I see considerable opportunities.

With the right level of commitment and concentrated effort, ammonia could replace LNG as the predominant alternative shipping fuel in the future, with significant scaling after 2030.

But, of course, we must continue to consider – and put to the test – a whole range of alternatives fuels and strategies.

As our Maritime Forecast to 2050 says, it’s equally important to keep in mind a number of essential measures towards maritime industry decarbonization, including greater energy efficiency, fuel flexibility and weighing up all Fuel Ready solutions.

When all is said and done, in the words of our DNV Maritime CEO Knut Ørbeck-Nilssen, “the true fuel of the future is collaboration”.

Yang Ming orders six LNG dual-fuel, ammonia-ready containerships from Hanwha Ocean

Taiwanese shipping firm Yang Ming Marine Transport Corporation (Yang Ming) and South Korean shipbuilder Hanwha Ocean on Wednesday (2 September) signed a shipbuilding contract for six 13,000 TEU class LNG dual-fuel container vessels. 

The contract was signed by Dr. Chuck Tsai, Chairman of Yang Ming, and Mr. Charles Kim, CEO of Hanwha Ocean. The vessels are scheduled for delivery between 2028 and 2029. 

They will complement Yang Ming’s existing fleet of 10,000+ TEU vessels and serve as key vessels on East-West services, with deployment flexibility across trade lanes connecting Asia with the East and West Coasts of North America, South America, and the Mediterranean. 

Each of the six new vessels will have a capacity of up to 13,650 TEU and feature LNG dual-fuel propulsion and Ammonia Fuel Ready specifications.

“As Yang Ming transitions toward net-zero emissions, LNG provides a relatively mature and economically viable alternative fuel solution, capable of reducing greenhouse gas emissions by approximately 20%,” the company said. 

“At the same time, ammonia can serve as a carbon-free fuel by utilising converted LNG storage facilities, while offering relatively lower conversion costs and comparatively well-developed supply chains and infrastructure. The Ammonia Fuel Ready design will therefore provide Yang Ming with greater flexibility in responding to increasingly stringent international regulations on greenhouse gas emissions.”

In addition, the vessels will be equipped with Type B LNG fuel tanks with a design pressure of 1.0 bar to enhance the safety and efficiency of LNG operations, together with a range of energy-saving technologies, including Wind Shields, Rudder Bulbs, Pre-Swirl Stators, and Shore Power Systems. Smart ship technologies and cybersecurity protection features will also be incorporated to enhance operational efficiency, safety, and reliability while effectively reducing fuel consumption and greenhouse gas emissions.

Deliveries under Yang Ming’s next-generation fleet optimization plan commenced earlier this year. By 2030, a total of 24 new vessels are expected to enter service. 

This includes 18 LNG dual-fuel vessels—comprising five 15,500 TEU, seven 16,000 TEU, and the six 13,000 TEU vessels under this contract—alongside six 8,000 TEU methanol dual-fuel-ready ships.

LR, China’s MARIC unveil tanker concept ready for three future bunker fuels

Lloyd’s Register (LR) and the Marine Design and Research Institute of China (MARIC) on Thursday (3 September) have secured Approval in Principle (AiP) for a new 114,000 DWT product and crude oil tanker designed to accommodate future conversion to LNG, methanol or ammonia.

Announced at SMM 2026, the concept addresses one of the biggest investment challenges facing shipping today: the need to develop vessels and capabilities that can support a range of alternative fuel options and pathways as technologies, infrastructure and regulations evolve.

While LNG is already a mature fuel pathway, methanol and ammonia remain at an earlier stage of development, with questions around global fuel availability, infrastructure development, economics and long-term adoption.

The 114,000 DWT tanker concept has been designed as a product and crude oil carrier that can accommodate future conversion to LNG, methanol or ammonia as technologies, regulations and fuel supply chains mature. By incorporating conversion readiness at the design stage, the concept aims to reduce future retrofit complexity and provide owners with greater confidence when planning long-term fleet investments.

The design concept was reviewed against LR’s July 2026 class rules and regulations, including requirements relating to ships using gases and other low-flashpoint fuels, alongside relevant IACS Common Structural Rules for oil tankers. Final classification and statutory approval remain subject to full compliance with all applicable rules and regulations.

Theo Kourmpelis, Global Business Director for Tankers, Lloyd’s Register, said: “Shipowners are being asked to make major investment decisions today despite continued uncertainty around which fuels will dominate in the decades ahead. Alternative fuel solutions each offer potential pathways to compliance, but fuel infrastructure, regulation and economics continue to evolve at different speeds around the world.

“Designs that preserve flexibility will be critical in helping owners manage risk while preparing for multiple future scenarios.”

Si Nan, Marine & Offshore Marketing Department Vice Director, MARIC, said: “As the industry explores different decarbonisation pathways, shipowners need vessel designs that can adapt alongside technological and regulatory developments. This concept was developed specifically to provide greater fuel flexibility and long-term resilience, allowing owners to respond to changing market requirements without being locked into a single fuel strategy.

“Receiving Approval in Principle from Lloyd’s Register is an important milestone that validates the design concept and supports its future development.”

DNV: Alternative-fuelled vessel orders hit highest monthly level since October 2024

Latest data from classification society DNV’s Alternative Fuels Insight (AFI) platform alternative-fuelled vessel ordering was strong in August, with 52 new vessels added to the platform.

This is the highest monthly total since October 2024 and follows another active month in July, when 47 vessels were added to the database.

LNG-fuelled vessels accounted for the vast majority of August activity, with 46 orders recorded. The container segment led the way with 30 orders, while the car carrier segment contributed a further 12 LNG-fuelled vessels. In addition, four ethanol-fuelled bulk carriers and two hydrogen-powered bulk carriers were added during the month, as well as one LNG bunker vessel.

The strong summer performance marked a significant acceleration in ordering activity after a relatively slow start to the year. In total, 242 alternative-fuelled vessel orders have been placed in the first eight months of 2026, representing a 27% increase compared with the same period in 2025.

LNG remains the dominant fuel choice, accounting for 63% of all alternative-fuelled vessel orders registered so far this year. Container vessels represent the largest share of these LNG orders (59%), followed by car carriers (30%).

Jason Stefanatos, Global Decarbonization Director at DNV Maritime, said: “The past two months have been particularly strong for alternative-fuelled vessel ordering, with August recording the highest monthly total we’ve seen since October 2024. This has helped lift year-to-date orders to a level well above the same period last year.

“LNG remains the leading fuel choice, driven largely by activity in the container and car carrier segments. These sectors have been among the earliest adopters of alternative fuels, supported by predictable liner operations and increasing demand from cargo owners to reduce emissions across supply chains. 

“For many owners, LNG offers a combination of emissions reductions, fuel availability and future flexibility while the longer-term fuel landscape continues to evolve. 

“At the same time, the latest figures include orders for ethanol- and hydrogen-fuelled vessels, highlighting that owners continue to explore a range of decarbonization pathways. Different segments are making different fuel choices, but the overall level of activity demonstrates continued investment in lower-emission shipping.”
