New liquid hydrogen carrier would transport green H2 from Scotland to Germany

C-Job Naval Architects has designed a new class of liquid hydrogen tanker in partnership with LH2 Europe. LH2 Europe will use the abundant renewable electricity in Scotland to produce green hydrogen and market it at a competitive price with diesel. The new tanker will transport the liquid hydrogen to terminals in Germany, with a strategic vision to expand supply to other markets as demand increases.


Hydrogen will be essential to the future of energy. It is up to us how quickly we can make that happen. LH2 Europe aims to have a full liquid hydrogen supply chain ready by 2027. We plan to initially deliver 100 tons per day (t/d) of green hydrogen and ramp up production to 300 t/d within three years, depending on demand.

This tanker design is a key step in providing the infrastructure to make that clean energy future a reality. Current vessels in operation are not able to deliver hydrogen at the scale we expect will be required to meet the needs of the market.

—Dr. Peter Wells, CEO of LH2 Europe


LH2 Europe in collaboration with C-Job Naval Architects developed an initial design for a liquid hydrogen tanker of 141 meters and a storage capacity of 37,500 cubic meters.

Liquid hydrogen provides unique challenges in ship design and engineering. As a comparison, LNG tankers use ballast water to compensate the loss of weight following delivery to ensure enough draft. As liquid hydrogen is high in volume but 20 times lighter than LNG, this required a unique solution. We have created a trapezium-shaped hull design which creates enough deck space to fit the tanks without the need for ballast.

The vessel is powered by hydrogen fuel cells and will be equipped with three liquid hydrogen storage tanks with total capacity of 37,500 m3—enough to refuel 400,000 medium-sized hydrogen cars or 20,000 heavy trucks. The tanks will have a much lower boil off than those currently used in the maritime industry.

The limited remaining boil off will be captured and directly utilized in hydrogen fuel cells, providing power to the vessel's propulsion systems, resulting in emissions of water only. The vessel itself will have zero greenhouse gas emissions during operations.

Vessel specifications

Length overall 141.75 m
Rule length 135.75 m
Breadth 34.90 m
Depth 8.75 m
Draught design 5.80 m
Installed power 5,000 kWe
Speed 14 knots
Accommodation 14 crew
Cargo tank capacity 3 x 12,500 m3

The ship is expected to be ready and commissioned six months before the first delivery of hydrogen in 2027.



Would not it be cheaper to transport electricity from Scotland to Germany




Australia plan to feed Singapour with large amount renewable electricity with high voltage direct current line, same between Morocco and UK project, just build HVDC line between Scotland and Germany much more efficient.

European Union never invest to develop HVDC Supergrid network (, much more sense than to generate clean H2, compress it to transport in liquid form, decompress, generate electricity.

The cheapest way to transmit energy is the use of pipeline, like H2 or Natural Gas pipeline. H2 pipelines can cost as little as 1/10 that of electricity powerline to transmit an average flow of energy over several days.
