Coordinated by Wärtsilä, an R&D group has been provided with €10 million for the Ammonia 2-4 project. The project aims to complete a retrofit for a two-stroke engine vessel by 2025, as well as establishing a laboratory demonstrator for an ammonia-fueled, four-stroke maritime engine.

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.
