Retrofitting vessels for ammonia fuel: new technical study from Grieg Star

By on March 21, 2023
Grieg Star and a series of high-profile maritime consortium partners have assessed the full feasibility for retrofitting a Grieg Star L-Class vessel to run on ammonia fuel. The study concludes that technical & regulatory challenges will not be showstoppers in the transition. A combination of high investment costs, uncertainty over ammonia fuel availability & pricing and slow market development remain the biggest barriers, presenting significant risks for first movers.

Mitigating emissions risks from ammonia-powered vessels

By on March 20, 2023
Technology solutions to manage emissions from ammonia-powered internal combustion engines will be commercially available on a similar timeline to the engines themselves, a new report from the Mærsk Mc-Kinney Møller Center concludes. Although the authors are confident ammonia combustion emissions (including the potent greenhouse molecule N2O) will be successfully minimised, key gaps include a lack of industry-wide emissions thresholds and a poor understanding of the well-to-tank emissions of ammonia fuel, particularly CCS-based ammonia.

Maritime ammonia: fuel cell propulsion systems, car carriers & bunkering in Germany

By on January 31, 2023

In maritime ammonia updates this week:

  • Alma Clean Power’s containerised SOFC system design has been granted AiP by DNV. A 2 MW, ammonia-fed system will be used to retrofit the Viking Energy vessel as part of the ShipFC project.
  • Grimaldi Group has increased its order for ammonia-ready car carriers to fifteen. China Merchants Heavy Industries will construct the 9,000 car equivalent units design at Jiangsu shipyards, delivering the first vessels in 2025.
  • Mabanaft and Hapag-Lloyd will explore the supply of ammonia bunker fuel to Hapag’s vessels at the Port of Hamburg (Germany), and the Port of Houston (USA).
  • and the German Federal Ministry for Economic Affairs and Climate Action will fund the construction of three, future-proof LNG bunker vessels, which are designed to be upgraded to handle ammonia fuel.
