LR: Safety and supply crucial for widespread adoption of ammonia bunker fuel

A new Lloyd’s Register report published on Thursday (21 March) has highlighted the need for industry-wide understanding of the operational and safety challenges surrounding the use of ammonia as a bunker fuel, for its adoption as part of the maritime energy transition.

Fuel for thought: Ammonia report found that although technology for ammonia as a marine fuel is developing rapidly, gaps in the regulatory framework around its use need to be addressed, alongside resolving the challenges for the production and supply of zero or near-zero emissions ammonia.

The report has identified that by taking steps to develop a framework today, the industry can avoid delays and build on the strong technology case for ammonia adoption.

For the safe handling and infrastructure, the maritime industry can draw on the extensive experience of transporting ammonia as a cargo throughout the 20th and 21st centuries. There are, however, still concerns around ammonia’s toxicity, crew awareness and training and its overall impact on aquatic, human and environmental health.

The study also found that among the factors to consider for ammonia adoption, social acceptance and scalability are key.

The pricing of renewable electricity, green hydrogen and carbon capture will all impact ammonia’s affordability as a marine fuel. Clean ammonia producers, who are looking to upgrade production to create blue and green ammonia, see potential in increased demand from agriculture and other sectors, as well as shipping, all putting pressure on supply.

Liam Blackmore, Principal Specialist – Decarbonisation at Lloyd’s Register, said: “Fuel for thought: Ammonia, underlines the importance of addressing regulatory gaps, technology application and production hurdles in order to ensure the seamless integration of ammonia into the marine fuel landscape as part of the maritime energy transition.”

“By proactively developing a robust framework today, it is possible to accelerate the adoption of this, whilst mitigating potential risks and hazards. LR is committed to supporting first movers in ammonia and other alternative fuels, drawing upon our extensive experience and expertise in maritime safety and regulation to help deliver innovative solutions that prioritise safety and reliability.”

LR’s is supporting ammonia pioneers in delivering designs and processes that are safe and reliable. In addition to being a founding member of the Castor Initiative, a joint development project for two deep-sea ammonia propelled tankers, LR will class Exmar’s ammonia-fuelled gas carriers currently under design development by Hyundai Mipo Dockyard.

LR has also issued approval in principle for ammonia-fuelled engine designs and technologies and has completed a risk assessment with Yara Marine Technologies and Pilbara Port Authority for ammonia supply and bunkering.

EXMAR’s “ANTWERPEN” completes first commercial voyage using ammonia bunker fuel

Belgian shipowner EXMAR on Monday (20 July) announced the successful completion of gas carrier ANTWERPEN’s first commercial voyage using ammonia as a marine fuel.

During its voyage from China to India, the vessel achieved ammonia dual-fuel operation fully in line with our expectations and design, demonstrating that the technology works in commercial service.

“Together with our partners, we continue to fine-tune the systems as we build on this outstanding achievement. We are proud of our crew for their excellent pioneering work,” the company said in a social media post.

Developed in close collaboration with HD Hyundai Heavy Industries, WinGD, Nord Gas Solutions (formerly Wärtsilä Gas Solutions), and Lloyd’s Register, ANTWERPEN is capable of carrying up to 46,000 m³ of ammonia or LPG and trading with close to zero emissions when using low-carbon ammonia fuel.

The vessel meets and exceeds current IMO emissions reduction targets, reducing greenhouse gases by up to 90% compared to conventional ships.

Manifold Times previously reported ANTWERPEN participated in a pipe-to-ship (PTS) ammonia bunkering operation in Ulsan Port.

The operation was carried out by Lotte Fine Chemical Co Ltd with 600 metric tonnes (mt) of green ammonia (NH3) supplied to ANTWERPEN.

KR, HD Hyundai tap first ammonia dual-fuel sea trial to develop vessel operating standards

Korean Register (KR) on Tuesday (14 July) said it is collaborating with HD Hyundai Heavy Industries (HHI) to establish a domestic operating environment for ammonia-fuelled vessels under the Ministry of Oceans and Fisheries’ Green Shipping Corridor Construction Support Project.

The initiative supports the development of ammonia as one of the most promising next-generation marine fuels.

HHI recently conducted a sea trial of Korea’s first ammonia dual-fuel propulsion vessel. The trial generated operational data on the vessel’s fuel supply system and engine, which will provide a valuable technical foundation for KR’s future development of domestic guidelines for environmentally friendly vessel operations and supporting wider maritime decarbonisation efforts.

A spokesperson for HD Hyundai, said: “Drawing on our group’s R&D capabilities and on-site technical expertise, we have made meaningful progress in advancing the application of ammonia as a marine fuel. We expect this to help enhance a sustainable maritime ecosystem while strengthening the competitiveness of Korea’s shipbuilding industry.”

Kim Daeheon, Executive Vice President of KR’s R&D Division, added: “The close collaboration between KR and HD Hyundai has enabled us to build the technical foundation for introducing ammonia-fueled vessels in Korea. We will continue to drive national projects forward together with HD Hyundai and establish technical standards befitting the era of Green Shipping Corridors.”
