New safety guidelines for the use of ammonia as fuel on gas carriers have been approved at the International Maritime Organization’s (IMO) Maritime Safety Committee (MSC 111), marking a step towards the commercial deployment of ammonia-fueled vessels.The guidelines, developed through collaboration between Lloyd’s Register (LR), the Belgian Federal Public Service Mobility and Transport (FPS Mobility) and gas shipping operator EXMAR, provide a practical framework to manage the safety risks associated with ammonia.By drawing directly on operational experience and regulatory input…

DNV’s Energy Transition Outlook Hydrogen to 2060 report explains why hydrogen won’t be the next LNG.LNG emerged to monetize geographically concentrated natural gas resources and move energy from a small number of exporting regions to distant markets. Hydrogen, by contrast, will be produced in all regions, predicts DNV.As a result, hydrogen systems are shaped primarily by local production, demand patterns, and balancing requirements rather than by global resource scarcity. Moreover…

Korean Register (KR) announced that it is serving as the Coordinator of two International Maritime Organization (IMO) expert groups in key marine environmental areas: ammonia effluent management and response procedures for nitrogen oxides (NOx) reduction strategy failures.As international pressure to reduce greenhouse gas (GHG) emissions from ships intensifies, ammonia-fueled vessels are gaining traction as a zero-carbon alternative to conventional marine fuels. However, ammonia's high toxicity means that ammonia effluent can be generated during vessel operation…

The Ulsan Port Authority (UPA) announced the successful completion of the world’s first ammonia bunkering operation for an ammonia dual-fuel gas carrier at Ulsan Port on April 23, 2026.This milestone builds on Ulsan Port’s earlier achievements, including the world’s first methanol bunkering demonstration (2023–2026) and simultaneous LNG bunkering operations for car carriers. With this latest development, Ulsan Port has, for the first time in the world, demonstrated ammonia bunkering for a commercial vessel via Port-to-Ship (PTS) operations…

Japan’s NYK Group has launched a lubricating oil analysis service to monitor the condition of ammonia-fueled engines, as it seeks to support the adoption of alternative fuels in shipping.The service, developed by group company Nippon Yuka Kogyo, is designed to detect early signs of abnormalities in engines using ammonia as fuel.Ammonia is seen as a next-generation maritime fuel due to its low greenhouse gas emissions during combustion, though it requires new approaches to monitoring engine performance.The service uses lubricating oil analysis to assess internal engine conditions…

Everllence has announced the successful factory acceptance test (FAT) of its first ammonia-burning engine built by licensee Engine & Machinery of Hyundai Heavy Industries (HHI-EMD) in South Korea.The dual-fuel Everllence B&W 6G60ME-LGIA (-liquid gas injection ammonia) type is slated for a vessel for Singapore-based, Eastern Pacific Shipping currently under construction at HD Hyundai Heavy Industries (HHI) in Korea. The engine also comes equipped with HPSCR (High Pressure Selective Catalytic Reduction) technology.The first very large ammonia carrier is scheduled for delivery in October 2026.

NYK Bulkship (Asia), Golden Island and Yara Clean Ammonia Norge have concluded a non-binding Term Sheet that paves the way towards a partnership to supply low-carbon ammonia as a marine fuel in Singapore.The companies began discussions in the beginning of 2024 to explore the launch of the business, aiming to commence operations within this decade.NYK group operates a fleet of more than 900 vessels. “With its potential to significantly reduce greenhouse gas emissions, ammonia is expected to play an important role in the future marine fuel mix.

Wärtsilä has announced that its 4‑stroke engine solution for ammonia fuel now offers a higher power rating. As part of the company’s ongoing development of ammonia‑fueled engine solutions, the upgrade to the Wärtsilä 25 Ammonia engine raises output to 315 kW per cylinder at 900 rpm and 345 kW per cylinder at 1000 rpm, matching the power level of the LNG‑fueled Wärtsilä 25DF engine. A key benefit of the upgrade is that fewer cylinders are required for a given power demand, which will reduce installation complexity and simplify maintenance.

Many claim to have ‘saltwater in their veins,’ but all you have to do is walk into the corner office of John McDonald, the new Chairman and CEO of the American Bureau of Shipping (ABS), to see that him saying “I was born into maritime” is not hyperbole. The first thing that greets you is a Dusan Kadlec nighttime painting of the Brooklyn Bridge, a painting that has special meaning to him as he fondly remembers being on a boat in New York harbor in 1983, his father USCG Captain of the Port of New York at that time, watching the fireworks over the bridge for the celebration.

Belgian shipowner Exmar has named two ocean-going ammonia dual-fuel midsize gas carriers, said to be the world’s first, marking a milestone in the development of low-emission shipping.The two vessels, ANTWERPEN and ARLON, were built in South Korea in cooperation with HD Hyundai as part of a multi-year development programme.Each vessel has a cargo capacity of about 46,000 cubic metres, including 45,000 cubic metre cargo tanks and two 500 cubic metre deck tanks. The design incorporates…

Swan Defence and Heavy Industries Limited (SDHI) has secured an order from Energy ONE Limited to build four ammonia dual-fuel bulk carriers, marking the first such vessels to be constructed in India.The contract covers four 92,500-deadweight tonne bulk carriers, which will be among the largest commercial ships built at an Indian yard, the company said.The vessels will measure about 229.5 meters in length with a beam of 37 meters and will be equipped with ammonia-fueled propulsion systems.

The trade of global fertilizer and ammonia faces intense pressure due to the effective closure of the Strait of Hormuz as diplomatic talks between the US and Iran remain uncertain. Rystad Energy’s 2025 trade mapping shows that the sale of 15% of global ammonia and 21% of urea, which is used as a high-nitrogen fertilizer, are tied to exporters potentially impacted by the closure. This includes leading producers Saudi Arabia and Qatar, followed by Kuwait, Bahrain, the UAE, Iran and Iraq.

lomarlabs has entered a collaboration with Blaze Energy to pilot a third-generation, compact, engine-integrated fuel reformer designed to accelerate the practical adoption of alternative fuels in commercial shipping.The collaboration will culminate in a pilot installation onboard a Lomar vessel, enabling Blaze Energy to validate its multi-fuel reforming system, under real marine operating conditions. The Flex-Fuel Reformer converts ammonia, methanol, or LNG into hydrogen directly onboard the ship…
