Bringing energy
to the maritime
industry
About us
Eyder’s mission is to pioneer a fleet of zero-emission vessels to distribute green ammonia across the Nordics and Northern Europe. With scalable, flexible designs tailored to customer needs, the ships will support shore power, rotor sails, and batteries.
Our concept portfolio includes multiple configurations, enabling ship-to-ship bunkering and ship-to-terminal flexibility—ideal for space-constrained ports. Optional Arctic class certification further enhances operational reach in demanding environments. As one of the world’s first vessels to both run on and deliver green ammonia, Eyder sets a new standard for sustainable maritime logistics.
A series of green vessels
Eyder has developed a portfolio of concept designs for vessels intended to distribute and bunker green ammonia, offering flexibility in both size and function to meet the diverse needs of end customers. These designs range from small-scale bunkering barges of 1,000 cubic meters to large-scale distribution vessels of up to 25,000 cubic meters.
The long-term ambition is to develop a series of vessels, called MS Green Ammonia, with the optimal size for each vessel determined by factors such as location, bunkering frequency, and volume. Through close dialogue with customers, Eyder can advise on vessel sizing, fuel pricing, and distribution costs, enabling trade optimization and tailored solutions that are both efficient and economically sustainable.

The first concept design
The first vessel concept developed is 7500 cbm and is equipped with two C-type tanks that store 5000 tonnes of green ammonia. The engines are dual fuel engines, which gives flexibility in an emerging market. With a length of 120 meters and a draft of 7 meters, the vessel is designed to access most ports along the Norwegian coast, with the option of supplying directly to other ships or to terminals for further distribution. Total loading capacity is 1,000 m³/h.
The concept design was developed with LMG Marin and was granted approval in principle in 2022. Supported by soft funding from ENOVA and The Research Council of Norway, Eyder aims to enhance the green ammonia value chain by connecting production sites with end-users through optimized voyage routes, ensuring competitive pricing.
