Dutch college students cross North Sea in hydrogen boat — however you gained’t trip one anytime quickly
A staff of scholars from the Technical College of Delft have made historical past by crossing the North Sea in a totally hydrogen-powered boat.
TU Delft’s Hydro Movement staff set off from Breskens, Netherlands on July 11, with 160km of tough ocean forward of them. Shortly into the journey, nonetheless, the vessel suffered a failure in its cooling pump and needed to dock in Belgium for repairs.
After a little bit of tinkering, the problem was resolved and the crew set sail as soon as extra. They arrived at Ramsgate, UK, 12 hours later. The boat, which cruises at 40km/h, made the journey utilizing simply 12 kgs of hydrogen gas.
The scholars began constructing the experimental vessel in August final 12 months. All the pieces — from the carbon fibre hull to the hydrogen propulsion system — was made out of scratch.

The eight-metre-long vessel is powered by a gas cell that sucks hydrogen from three storage cylinders and converts it into vitality. This vitality feeds right into a battery pack which in flip powers the motor.
TU Delft college students have been engaged on greener boat designs for nearly 20 years. For over a decade the college championed the event of solar-powered boats, making the swap to hydrogen 4 years in the past.
Hydrogen energy
The Hydro Movement undertaking goals to show the viability of hydrogen as a gas supply for ships, that are one of many hardest types of transport to decarbonise. The worldwide transport business contributes 3% of worldwide carbon emissions — greater than air journey.
Hydrogen is the “finest technique to retailer inexperienced vitality,” mentioned the Hydro Movement staff on their website. “When transformed by gas cells it has an vitality storage density roughly 235 occasions bigger in comparison with business commonplace lithium-ion battery cells.”
Hydrogen boats have been making vital headway in recent times. In 2021, Norway launched MF Hydra, the world’s first hydrogen-powered ferry. The nation just lately started building two extra of the vessels.
Nonetheless, most hydro boats right this moment are very like TU Delft’s — experimental prototypes not designed for business use.
The principle drawback with bringing them to the market is value and infrastructure.
Hydrogen, particularly the inexperienced selection, made utilizing renewable vitality, shouldn’t be obtainable in massive portions right this moment. There are additionally a number of technical challenges in dealing with the gas safely and making it cost-competitive with diesel.
