Two SeaShuttles Could Decide the Future of Liquid Hydrogen at Sea
Two commercial container ships, 6.4 MW of fuel cells, 17 tonnes of
liquid-hydrogen storage and more than 3,000 hours of planned real-world
testing will finally expose the numbers that hydrogen shipping has been
missing: fuel consumption, bunkering time, reliability and cost per box.

The experiment is no longer simply whether a fuel cell can propel a
ship. It is whether a repeatable commercial corridor can make hydrogen
available, affordable and operationally invisible to the cargo customer.
Hydrogen shipping has spent years in feasibility studies, concept drawings and pilot craft. Samskip's SeaShuttle project is approaching a different test. These vessels are intended to carry paying container freight on a scheduled service between Rotterdam and Oslo.
The first vessel is currently scheduled to enter service in the second quarter of 2027. During an 18-month HyShip demonstration, the project intends to collect more than 3,000 hours of operating data covering sailing, port manoeuvring and hydrogen bunkering.
That makes the commercial question unusually measurable. A successful demonstration must show more than zero exhaust emissions. The ships must maintain schedule reliability, bunker without damaging port turnaround, secure enough liquid hydrogen at a repeatable price and keep the freight premium small enough that customers will actually use the service.

Why this route
Hydrogen gets a much easier commercial test when the route never changes
Oslo-Rotterdam Green Corridor
Fixed ports, predictable cargo and repeatable bunkering
Norway
Oslo
SeaShuttle
Netherlands
Rotterdam
Published route references place the practical corridor at roughly
555-650 nautical miles depending on routing and operating pattern.
Fixed-route shipping removes one of hydrogen's biggest weaknesses.
The operator knows where the ship will refuel, how far it must sail,
which terminals it will use and roughly how much energy each voyage
requires. Deepsea tramp shipping rarely offers that level of certainty.
The 17-ton tank
The range problem looks manageable on this specific corridor
Energy calculations use hydrogen LHV of 33.3 kWh/kg and Ballard's
published 53.5% peak fuel efficiency.
Stored H2
17 t
Roughly 240 cubic metres of liquid hydrogen
Liquid hydrogen density is approximately 70.8 kg/m³. Cryogenic containment and system space make the installed package larger than the liquid volume alone.
Chemical energy
~566 MWh
The tank carries a large amount of energy by mass
Hydrogen has excellent gravimetric energy density even though its volumetric energy density remains low.
Peak conversion
~303 MWh
Electrical energy at 53.5% peak fuel-cell efficiency
This is a theoretical energy screen. Actual ship performance will vary with fuel-cell load, auxiliaries, batteries and operating conditions.
Full 3.2 MW
~95 h
Nearly four days at the full rated fuel-cell output
Actual average propulsion demand should be below maximum installed power for much of a normal voyage.
From order to operation
The project has already shown how difficult first-of-a-kind shipping can be
March 2023
Two vessels ordered at Cochin Shipyard
The original shipyard announcement targeted deliveries beginning
in the third quarter of 2025.
February 2024
Steel cutting begins
Physical construction starts on the first SeaShuttle.
2026
SeaShuttle becomes HyShip's commercial demonstrator
The project now combines the vessels, bunkering infrastructure,
hydrogen supply and regulatory work inside one demonstration program.
End 2026
Current target for first yard delivery
Samskip says final hydrogen upgrades will follow in Rotterdam.
Q2 2027
First commercial SeaShuttle service
Current target for Rotterdam-Oslo operations.
2028
Preferred Rjukan LH2 supply begins
Norwegian Hydrogen currently expects industrial-scale deliveries
from Rjukan to begin in 2028.
The timetable contains a fuel-supply question.
The vessel is currently scheduled before the preferred Rjukan supply
project starts deliveries. That makes interim hydrogen sourcing an
important part of the 2027 commercial demonstration.
Fuel-price threshold
Today's unusually expensive MGO makes hydrogen look much closer to parity
ShipUniverse model using a 2 MW average electrical load, 600 nm passage,
53.5% fuel-cell efficiency, 45% diesel efficiency and $90/tCO2.
MGO comparator
~$5.60/kg
VLSFO comparator
~$3.25/kg
Model LH2 case
$7.00/kg
The conventional fuel chosen for comparison changes the answer dramatically.
Rotterdam MGO was about $1,390/t on September 29 while VLSFO was
roughly $686.50/t. A commercial hydrogen case therefore cannot be
reduced to a single universal $/kg break-even point.
The customer-level question
A fuel premium can look very different when divided across the containers
Modeled H2 / 600 nm leg

Equivalent MGO

Fuel parity is not the same thing as vessel parity.
The calculation above does not include higher vessel CAPEX, cryogenic
systems, bunkering infrastructure, maintenance, financing or first-of-a-kind
engineering. It isolates the recurring fuel decision so the remaining gap is visible.
Fuel supply
The planned hydrogen plant is large enough to matter, but timing matters more

Building the first corridor
Commercial proof is being heavily de-risked before the market has to stand alone
SeaShuttle
NOK 148.6M
Enova vessel-project support
Norwegian public support for the zero-emission vessel development.
HyShip
€7.99M
EU contribution
HyShip's total project budget is approximately €10.87 million.
Rjukan LH2
€31.5M
EU CAPEX support
Separate support for the industrial liquid-hydrogen production chain.
Rjukan OPEX
€13.2M
Hydrogen Bank operating support
Separate support intended to narrow the cost gap during early operation.
These figures should not be added together as one ship subsidy.
They belong to different vessel, demonstration and fuel-supply projects.
Their significance is that commercial liquid hydrogen requires an entire
ecosystem to be de-risked simultaneously.
The five commercial gates
Three thousand hours will matter only if these numbers hold together
Range
Does the 17-ton tank provide comfortable operating margin?
The base energy calculation suggests the route is technically
compatible with the storage scale. Weather, reserve margin and
auxiliaries still need real-world validation.
Fuel
Can delivered LH2 reach a repeatable commercial price?
Production cost alone is not enough. Liquefaction, storage,
transport and bunkering must all fit inside the final $/kg.
Bunkering
Can cryogenic refuelling fit inside liner turnaround?
A technically successful bunkering system still fails commercially
if it repeatedly delays a scheduled container service.
Reliability
How often does the vessel need backup generation?
The ships include backup generators for endurance and resilience.
Every hour of backup operation changes the zero-emission result.
Freight
Is the remaining cost premium small enough per container?
Customers buy transport, not hydrogen. Commercial success depends
on converting the system cost into a freight premium the market will accept.
Policy advantage
European regulation gives renewable hydrogen more value than its energy content alone
FuelEU RFNBO reward
2×
Renewable fuels of non-biological origin can receive a double
multiplier in FuelEU GHG calculations through 2033.
ETS phase
Full
Covered 2026 emissions enter the fully phased maritime ETS obligation.
Regulation changes the commercial break-even point.
Renewable hydrogen can create FuelEU compliance value while avoiding
the carbon allowances associated with conventional fuel. The exact value
depends on route, vessel scope, fuel certification and fleet compliance strategy.
Replication boundary
Oslo-Rotterdam can prove hydrogen works without proving it works everywhere
| Operating model | Fuel certainty | Storage challenge | Infrastructure | Hydrogen fit |
|---|---|---|---|---|
| Fixed shortsea corridor | High | Manageable | 1-2 planned hubs | Strongest |
| Regional liner network | Moderate | Moderate | Multiple hubs needed | Possible |
| Deepsea fixed liner | Moderate | Large | Global bunkering needed | Difficult |
| Tramp bulk / tanker | Low | Large | Unpredictable ports | Weak fit today |

This is a screening model rather than a vessel performance prediction.
Hydrogen LHV is fixed at 33.3 kWh/kg, conventional marine fuel LHV at
11.86 kWh/kg and conventional CO2 emissions at 3.206 tCO2 per tonne
of fuel. The delivered LH2 input must include production, liquefaction,
logistics and bunkering if the result is being used for commercial
comparison. Vessel CAPEX, fuel-cell replacement, hydrogen boil-off,
port infrastructure, financing, FuelEU pooling value, grants and customer
green premiums are not included in the core fuel comparison.
