Green Technology Redefines Navigation, Powered by 192 Solar Panels and 37,500 kWh of Clean Energy Annually.

Get ready for a new era in navigation. The world’s first hybrid solar cargo ship, the Blue Marlin, is ready. It promises to transform cargo transport, combining innovation and sustainability.

The Partnership Between Wattlab and HGK Shipping Revolutionizes

The decarbonization of waterway transport gains massive momentum. This is thanks to a visionary partnership between the Dutch Wattlab, a solar energy specialist, and the German HGK Shipping, a giant in inland shipping. The hybrid solar cargo ship Blue Marlin is the result of this union. Its baptism ceremony took place in Hamburg, Germany, on July 3rd. This milestone seals the commitment to a greener future.

How the Blue Marlin Generates 37,500 kWh/Year of Clean Energy

The technology onboard the Blue Marlin is impressive. It features 192 solar panels that generate an astounding 37,500 kilowatt-hours (kWh) of electricity per year. The installation took place at the De Gerlien van Tiem shipyard in the Netherlands. This solar energy powers the onboard systems and, crucially, the ship’s propulsion. The Blue Marlin is the first inland transport vessel to depend directly on solar energy. Furthermore, it has a “Future Fuel Ready” diesel-electric propulsion system and optimization to operate in shallow waters. The SEAFAR technology allows for remotely controlled navigation.

Efficiency and Sustainability in Shallow Waters

With a length of 86 meters and a width of 9.5 meters, the Blue Marlin is designed for maximum efficiency. Its draft of only 1.10 meters is perfect for operations in shallow waters. Maneuverability is ensured by Veth twin propellers and a bow thruster. Its modular design allows for barge coupling, increasing its capacity to up to 3,110 tons of cargo. The hybrid solar cargo ship mainly transports bulk goods for Salzgitter AG, one of Europe’s largest steel producers.

Less CO2, More Efficiency in Inland Transport

The solar installation of the Blue Marlin operates in harmony with four diesel generators. This synergy allows for “peak shaving,” reducing energy consumption during peak hours. The automated energy management system distributes electricity precisely, optimizing efficiency and cutting fuel consumption. The expectation is a significant reduction in CO2 emissions, potentially reaching 36,000 kg per year. The hybrid solar cargo ship Blue Marlin has already been recognized with the prestigious Gold Green Award. It is a giant step towards sustainability in logistics.

Mother and daughter build a 70 m² house with more than 8,000 discarded glass bottles and impress with their creativity; known as the Casa de Sal, the property is located on Itamaracá Island, in Pernambuco.

Workers were opening a new road connection near the Marginal Tietê when they found, in the underground of the construction site, remnants of locomotives, wagons, and boilers from the 19th century linked to the forgotten history of Lapa.

Instead of burning or burying old tires, an American city is transforming about 2,000 of them into the street itself, paving its first sections with a quieter and more durable rubber asphalt.

China transforms desert-devastated area into the world’s largest artificial forest, planting trees for 60 years, blocking sand that reached Beijing, and creating a “green lung” of 92,000 hectares in a region once considered lost.

Greek island offers free housing for volunteers, but there’s a condition: you need to take care of rescued cats.

Engineers want to carve through Africa with a giant canal to bring water from the world’s second-largest river to a dying lake on the edge of the Sahara Desert that has already lost 90% of its water.

China has deployed snake-shaped robots to slide along power lines, where they have already inspected over 130 kilometers of cables using cameras and sensors to detect damaged wires, worn-out parts, and overheating.

Malaysia created a tunnel that becomes a road on a normal day and a giant flood drain when rain threatens Kuala Lumpur.

Owner of Tok&Stok and Mobly raises alert in retail, sees debt exceed R$ 1 billion and rushes to court to try to save stores, jobs, and essential operations

Forget the image of a frozen and still continent: scientists have just revealed hundreds of earthquakes beneath East Antarctica, in an area where no one expected to find this phenomenon.

While almost everyone depends on the supermarket, Ângelo, 36, and his aunt Inês, 75, go to the market only to buy salt, coffee, and cleaning products; everything else comes from their own land in Casca, Rio Grande do Sul.

Libya built over 4,000 kilometers of underground pipelines to bring water from the Sahara to coastal cities in a project that the government itself called the Eighth Wonder of the World.

While giant ships still burn heavy fuel and the maritime sector races against climate targets, Maersk and Vale are starting to bet on ethanol as a new route to reduce emissions at sea.

China begins construction of the world’s largest LNG ship, a 344-meter giant capable of supplying 4.7 million homes for a month, carrying 271,000 m³ of gas, and placing QatarEnergy in the largest naval order ever recorded in world history.
