Norwegian technology developer Pherousa announced that it has developed & validated an ammonia cracking-based propulsion system, with plans to order six Ultramax vessels fitted with the technology. Grieg Maritime has ordered up to four ammonia-ready bulk carriers from China State Shipbuilding Corporation for delivery in 2026. And a new container ship design has been unveiled by the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping.

Three new ammonia-powered, bulk carrier designs have recently been awarded Approval in Principle. In China, SDTR Marine & SDARI’s Kamsarmax dual-fuel design received AiP from the China Classification Society. In Japan, another Kamsarmax-sized vessel developed by Sumitomo and Oshima Shipping was approved, and ClassNK has signed off on a Capemax vessel designed by MOL and Mitsui & Co., which includes an ammonia-powered main engine and hard sails to improve energy efficiency.

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.

Based on recent press reports, ammonia has a new friend: methanol. With the two upstart fuels being mentioned together with increasing frequency, they seem poised to develop on parallel paths as each seeks market applications where it can become a mainstay solution.

Welcome to the Ammonia Wrap: a summary of all the latest announcements, news items and publications about ammonia energy. In this week's wrap: HyDeal Ambition, new marine tankers, fuel forecasts & SOFC developments, a new technical briefing on power generation, UNSW leads research in P2X, GWs of green ammonia in Denmark, Norway and Chile, green ammonia in the Orkneys, new government focus on ammonia in South Africa, and India to make green ammonia production mandatory?

Three separate projects to design a range of ammonia-fueled vessels were announced last week at a shipping industry conference in China. Lloyd's Register has granted Approval in Principle (AiP) for the design of a 180,000 ton bulk carrier. ABS announced a project to "produce designs for an ammonia-fueled Chittagongmax container carrier of 2700 TEU capacity." And Lloyd's Register also announced a project for "an ammonia-fuelled 23,000 TEU Ultra-Large Container Ship (ULCS) concept design." All three projects are working with the two-stroke ammonia engine developed by MAN Energy Solutions, and all are led by major shipbuilders in China.
