Hydrotug 1: the very first hydrogen-powered tug

Port of Antwerp-Bruges and CMB.TECH joined forces to create the world's first hydrogen-powered tug. The Hydrotug 1 will be sailing around Antwerp from 2024.

The Hydrotug 1 consists of two innovative dual-fuel BeHydro engines that can run on either hydrogen or traditional fuel. This tug is part of an integrated greening programme for the Port of Antwerp-Bruges fleet and is being deployed as a major step in the transition to a climate-neutral port by 2050. With the Hydrotug 1, CMB.TECH is affirming its international pioneering role in the transition to ships powered by environmentally friendly fuel.

The Hydrotug 1 is the first hydrogen powered tug in the world and is part of the greening programme of the Port of Antwerp-Bruges fleet.

In figures

  • The Hydrotug 1 consists of two BeHydro V12 dual-fuel medium-speed engines that can run either on hydrogen or on traditional fuel. 
  • The tug has a length of 30.17 metres, a width of 12.5 metres, a weight of 678.8 tons and a bollard pulling power of 65 tons.
  • The tug can store 415 kg of compressed hydrogen in 54 gas cylinders installed on the deck and eliminates emissions equivalent to 350 cars.

Where was the Hydrotug 1 made?

The Hydrotug brings together a lot of European technology and expertise. The tug itself was built in Spain and made ready for use at IDP Shipyard in Ostend. The BeHydro engines are Belgian-made, while the generators are Swedish and the exhaust system is Swiss. The vessel's wheelhouse, by Alphatron Marine, is a Dutch design. The hydrogen technology on board the tugboat was developed and built by the Antwerp company CMB.TECH. The towing winch and anchor winches come from Brusselle Winches & Steering Gear from Zeebrugge and one of the compressors was supplied by Atlas Copco in Antwerp. 


And don't forget: the crew of the Hydrotug 1 comes 100% from Port of Antwerp-Bruges!

What is hydrogen?

Hydrogen is the simplest and most abundant element in our universe. In its pure form, it occurs as hydrogen gas (H2).


Hydrogen plays an important role in the transition to a climate-neutral world. Despite its energy-intensive production, it produces no emissions when burned and can be produced in an entirely green way.


It can be used for a variety of applications – in the case of the Hydrotug 1, as a fuel. In addition, it can serve as an alternative energy source or a raw material in industry as well.

Depending on the energy sources and CO2 emission from the production process, we speak of gery, blue or green hydrogen.


The Hydrotg 1 is a collaboration between Port of Antwerp-Bruges and CMB.TECH.
