SWITCH Marine on Tuesday (30 November) said the world’s first hydrogen fuelling of a commercial marine vessel has been successfully completed .

On 18 November at All American Marine shipyard; the vessel began its final sea trials before delivery. 

The event is a monumental step towards decarbonisation of the worldwide shipping industry and showcases the United States’ energy transition away from fossil fuels, it states.

The new 75-passenger ferry Sea Change received hydrogen into its 242 kg tanks on the upper deck. It uses hydrogen in fuel cells producing electricity to power electric motors for distances up to 300 nautical miles, and speeds up to 20 knots – similar capabilities as diesel-powered vessels – with the added benefits of zero exhaust smoke or other emissions and very little vibration and noise.

The fuel loaded in the vessel’s tanks includes green hydrogen, produced in California by an electrolyzer powered with renewable solar power, which results in zero carbon emissions in the production of the fuel as well.

“While it’s taken us years to get to this point, the timing couldn’t be better,” says Pace Ralli, CEO of SWITCH Maritime. 

“In this moment, our nation is more committed than ever to making the transition to a carbon-free economy. Hydrogen will play a major role in that future, and major players in the maritime industry are ready to decarbonise. We are grateful to all our partners, and proud to play a small role in accelerating the widescale adoption of hydrogen power. Hopefully this is just the first domino to fall.”

The fueling follows the regulatory approval in October by the United States Coast Guard (USCG) of the hydrogen powertrain and storage systems onboard the Sea Change, representing the culmination of years of cooperation with the USCG focused on safely integrating hydrogen power and storage systems on passenger vessels. 

The achievement of the significant milestone unlocks the possibility of many future deployments of similar hydrogen power systems on all vessel types – including ocean-going containerships.

Zero Emission Industries (ZEI), formerly Golden Gate Zero Emission Marine, is responsible for the design and development of the first-of-its-kind maritime hydrogen and fuel cell system as well as the vessel’s unique fueling system that allows it to be fueled directly from a hydrogen truck, and was responsible for the successful regulatory approvals of all hydrogen-related aspects onboard. 

ZEI is a cutting-edge hydrogen technology company that develops and sells turnkey hydrogen power systems, advanced fuel cell balance of plant sub-systems, fueling systems, and proprietary safety systems for a range of applications.

“We’re super excited to see the Sea Change start sea trials, and I felt proud watching our fueling and hydrogen systems operate in the real world for the first time,” added Danny Terlip, Lead Engineer at ZEI. 

“Our whole mission at ZEI is to build new technology that makes hydrogen accessible and easy to use, and this event demonstrates how far we’ve come.”

For the fueling during sea trials, SWITCH has engaged West Coast Clean Fuels (WCCF) to develop and permit the end-to-end clean fuel supply chains that will deliver hydrogen to the Sea Change, as well as BayoTech, for high-pressure gaseous hydrogen delivery to Sea Change during sea trials in Washington using transport trailer-to-ship transfer.

SWITCH’s vision is to achieve a fully zero-carbon fueling supply chain of green hydrogen, which is currently in short supply in the US. Building more and larger vessels that demand large volumes of hydrogen offtake will increase green hydrogen production volumes, and drive the cost of hydrogen lower than diesel, further advancing the rollout of hydrogen-fueled fleets.

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.”
