Flexible ammonia production technology is currently scaling up to meet the challenges of fluctuating electricity feedstock. The ability to ramp down plants to 5 - 10% of their nominal load will minimize the requirement for hydrogen storage buffers and reduce the overall cost of renewable ammonia production. The first demonstration-sized flexible ammonia plants are due to begin operations later this year.
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.
WinGD and CMB.TECH will team up to develop & deploy ammonia-fueled, two-stroke engines in ten Capesize bulk carriers, to be built at the Beihai shipyard in China. The pair will continue development of WinGD’s dual fuel X72DF design, which was first announced in December 2021. Delivery of the vessels is due in 2025-6.
In maritime ammonia updates this week:
Topse & Mintal Hydrogen will develop a dynamic, renewable ammonia plant in Baotou, China. Similar to Topsoe’s project in Skovgaard (Denmark), the electrolyser plant in Baotou will be directly connected to renewable energy generation, with production to begin in 2025.
Amon Maritime has launched a new subsidiary - Amon Offshore - which will build, own and operate a fleet of ammonia-powered platform supply vessels, to operate off Norway’s coast. The new PSV design has already received AiP for ammonia notation from DNV, and preliminary flag approval from Norwegian Maritime Authorities. We also explore two more AiP for ammonia-powered vessels in China: a 16,000 TEU container ship and a 50,000 tonne, mid-range oil/chemical tanker.
Since the Clydebank Declaration was signed last December, the prospect of ammonia-fueled, green maritime corridors has been steadily rising. The Global Maritime Forum has just released a valuable discussion paper on potential definitions and approaches for green corridors. Recent announcements in Europe, Singapore, Australia and the Nordic countries demonstrate growing momentum. For maritime stakeholders to capture early learnings and best manage the complex task of alternative maritime fuel scale-up, the opportune time is right now.
