A zero-emission interregional cargo ship  

Energy Observer, via its subsidiary EOConcept, a pioneer in sustainable maritime solutions, has launched the Energy Observer 2 project in 2022 with the ambition of designing the world’s lowest-carbon cargo ship. EO2, an advanced demonstrator combining cutting-edge engineering and innovative technologies, aims to transform maritime transport towards low-emission solutions. This European funding marks a crucial step towards the construction and operation of the world’s largest liquid hydrogen-powered cargo ship by 2029, supporting the transition to environmentally friendly maritime technologies. 

The current design of the EO2 is a 160-meter container ship, capable of carrying up to 1,100 TEU containers with a range of 14 days, corresponding to 1,600 nautical miles. Equipped with electric propulsion powered by 4.8 MW of fuel cells developed by EODev and its industrial partner Toyota, this vessel represents a breakthrough in low-carbon maritime technologies. Scheduled for commercial operation from 2029 on Europe’s Atlantic and Channel coasts, EO2 could reduce CO₂ emissions by 112,250 tonnes over ten years, equivalent to the annual absorption of 190,000 mature trees. This pioneering project aims to demonstrate the technical and economic viability of liquid hydrogen for maritime transport on short segments, consolidating Europe’s position as a leader in the energy transition
