Approval in Principle from Korean Register for two ammonia-fueled vessels

Korean Register has granted AiP for two more ammonia-fueled vessel designs: a 60,000 m3 carrier and a 38,000 m3 ammonia transport/bunkering vessel. Both designs were developed by Korea Shipbuilding & Offshore Engineering, with assistance from Hyundai Heavy Industries. Importantly, the new AiPs mark the first milestone achievement for the 'Green Ammonia Shipping/Bunkering Consortium', which was launched in May 2021 with the explicit purpose of developing ammonia-fueled ship designs for approval by Korean Register.

Ammonia combustion analysis: powertrains, turbines & power generation

This week we explore four updates in ammonia combustion R&D:

1. A team from the University of Cambridge has shown merchant vessels are the strongest candidates for conversion to run on ammonia powertrains, with cargo capacity losses of 4-9% able to be feasibly offset by operators.

2. Researchers at the University of Minnesota have successfully tested a thermochemical recuperation (TCR) reactor to improve the efficiency of a dual-fuel, diesel-ammonia compression ignition engine by minimising ammonia slip.

3. A global team led by Cardiff University researchers has revealed some of the inner workings of ammonia combustion in gas turbine flames.

4. A global team has produced a cradle-to-gate environmental assessment for ammonia production and ammonia-based electricity generation, suggesting that renewable and nuclear ammonia have a significant role to play in decarbonising the power sector.

WinGD to develop ammonia maritime engines by 2025

Swiss-based engine developer WinGD has announced that its current portfolio of low-speed maritime engines will be ready to operate on methanol and ammonia by 2024 and 2025 respectively. Although WinGD's diesel-fueled X Engine series will require retrofits, the X-DF Engine series is already designed to run on biogas and will not require major modifications to run on methanol or ammonia.

Kawasaki Heavy’s LPG/ammonia carrier in demand

Kawasaki Heavy Industry's 86,700 m3, LPG and "liquefied ammonia gas" (LAG) carrier has been ordered for the fifth time in 2021. K Line, Eneos (two vessels) and now NYK (also two vessels) will take delivery of the VLGCs from KHI's Sakaide shipyards in 2023 (K Line and Eneos), and 2024 (NYK). The flexibility of the dual-purpose LPG/ammonia carrier is key to its newfound popularity.

Fortescue, LMG Marin and Eidesvik to launch ammonia-powered ships

Four ammonia-powered ships were announced this week, with a mixture of retrofits and newbuilds. Fortescue Future Industries will convert the MMA Leveque to run on near 100% ammonia fuel within 12 months. Grieg Maritime and Wartsila's MS Green Ammonia vessel has a designer, with LMG Marin engaged to complete a concept by mid next year. And Eidesvik, Aker BP and Alma (formerly Prototech AS) have joined forces to deploy the ammonia-fed fuel cell technology being developed for the Viking Energy project.

Maritime Ammonia Fuel – Stepping Forward

Clearly, by now it is a great understatement to say that ammonia as a maritime fuel has potential or could be developed as an alternative to fossil maritime fuels. Enablers for maritime ammonia fuel are being developed and we have moved past simple potential. In terms of on board technology, supply and other critical areas, maritime ammonia fuel is stepping forward. However, we are only starting out and the road ahead remains long, unclear and of course paved with many potential barriers. We welcome therefore the dedication and quality of work being undertaken by many different entities to help untangle complexity and illustrate pathways. Within…

Wärtsilä & Møkster join forces, Japanese maritime consortium takes next steps

Wärtsilä and Simon Møkster Shipping will explore the feasibility of using ammonia as the main fuel in dual fuel engines. Currently Møkster's fleet operates on LNG. In Japan, NYK Line, Japan Engine Corporation, IHI Power Systems, Nihon Shipyards and ClassNK will all collaborate on a demonstration project of ammonia-powered vessels in Japan. First announced in 2020 with three vessel concepts, two of the three vessel designs now have a commercialisation schedule fully defined (the A Tug and the AFAGC).

Maritime ammonia: vessel conversions and new engines by 2023

Eidesvik Offshore and Wärtsilä will cooperate in the world's first ammonia conversion project, with an existing offshore supply vessel (OSV) to be retrofitted with an ammonia-fueled combustion engine, fuel supply and safety system. The project has a completion date of late 2023. In the engine space, MAN ES has signed a new agreement with Mitsui E&S and Mitsui O.S.K. Lines (MOL) to have purchase contracts for its low-speed, ammonia-fueled main vessel engine finalised in 2023.

ABS publishes new guide for ammonia-fueled vessels

As part of its efforts to support the adoption of ammonia as an alternative maritime fuel, the American Bureau of Shipping has published a new, comprehensive guide to ammonia-fueled vessels. ABS joins DNV GL, the Korean Register, RINA and Bureau Veritas in publishing ammonia-ready notations, fuel guidelines & vessel guides this year.
