Transatlantic Green Ammonia Bulk Carrier Pilot

Ammonia has been highlighted as one of the more promising future fuels in order to achieve reduced CO2 emissions from shipping. The industry has gained experience with the transportation of ammonia, but there are still several uncertainties related to how well it will work as a fuel for long-distance transportation. This feasibility study (owned by Grieg Maritime Group and facilitated by Green Shipping Program) has evaluated whether it is sustainable to retrofit a ten-year-old ship to operate on green ammonia in a transatlantic trade today.

Project Objective:

The objective of the pilot’s study phase has been to assess the technical and commercial feasibility of retrofitting an open hatch bulk carrier for green ammonia operations in a trans-Atlantic route. What are the key barriers, risks, and possibilities? How does the business case look, and is green ammonia viable as fuel on this specific trade? The pilot-case relates to a specific vessel type, in a defined geography (Europe, North- and South America) with an established value chain. Through five work-streams, commercial, technical, infrastructural, financial and operational aspects were explored.
