Green Ammonia Volume Analysis – A Roadmap Towards 2030

Yara Clean Ammonia, together with NCE Maritime CleanTech and with analysis support from DNV, have delivered a volume analysis and roadmap for the use of renewable ammonia in the Norwegian domestic shipping sector. With the right policy levers in place, renewable ammonia can meet and reach beyond the 2030 decarbonisation targets for the Norwegian domestic fleet, reducing emissions by as much as 69%.

Ammonia vessel updates: the Castor Initiative, MS Green Ammonia & post-Panamax bulkers

Five ammonia vessel updates this week:

1. An ammonia/liquefied CO2 carrier concept design from Mitsui O.S.K. Lines & Mitsubishi Heavy Industries.

2. Approval in Principle for an ammonia-fueled car carrier designed by China State Shipbuilding.

3. Approval in Principle for the MS Green Ammonia.

4. An MoU between three members of the Castor Initiative to design & construct two Very Large Crude Carriers.

5. A concept design for up to four types of ammonia-ready, LNG-fueled vessels (ARLFV) from NYK Line.

Ammonia-ready, ammonia-fueled and on-water ammonia production

Following last month’s shipbuilding news from China, this week we explore three ammonia-related announcements from Norway-based players:

1. Breeze Ship Design’s ammonia-fueled oil tanker design, with a demonstration vessel to be eventually chartered to Equinor.

2. An order for six ammonia-ready, robotic offshore vessels from VARD.

3. And the P2XFloater, a new vessel concept from H2Carrier for the world’s first floating, industrial-scale ammonia production plant.

Ammonia-ready vessels: new contracts & deliveries in China

This week we explore a trio of announcements out of China:

1. The ammonia-ready vessel Kriti Future has been delivered to owners Avin International.

2. Höegh Autoliners has contracted China Merchants Heavy Industry to build at least four of their new ammonia-ready vessel design: the Aurora-class car carrier. The new builds will meet requirements for DNV GL's methanol and ammonia-ready notation guides.

3. And Swiss-based shipping giant MSC has placed an order for six ammonia-ready container ships from Dalian Shipbuilding in China. The vessels will be powered by WinGD dual-fuel engines, for which retrofits will be available by 2024/5 to run on methanol and ammonia.

New ammonia-powered vessels: Newcastlemax & Panamax class

Rio Tinto and AngloEastern have announced they will develop Newcastlemax class, ammonia-powered bulk carriers. The dry cargo vessels will be the maximum size allowed to dock in the Port of Newcastle, Australia: an important coal & iron ore port in global maritime trade. Both AngloEastern and Rio Tinto are members of an Itochu-led maritime fuel study investigating the use of ammonia. In Japan, a "greener ships" consortium has produced its first-ever ammonia-powered design: a Panamax-class bulk carrier. And the China State Shipbuilding Corporation will develop two 93,000 m3 ammonia-powered ammonia carrier vessels, with Bureau Veritas granting AiP for the vessel design.

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.
