A recent publication by Wattlab highlights an exciting growth in lasting shipping: the launch of the Blue Marlin, the first hybrid inland cargo vessel powered by solar energy, in collaboration with Germany’s HGK Shipping.

This innovative vessel boasts 192 solar panels that not only power its onboard systems but also drive its high-voltage propulsion system. This marks a significant leap forward,as Blue Marlin is now recognized as the first inland ship to harness solar energy for actual movement rather than just basic functions.

HGK Shipping plays a crucial role in European inland waterway transport, managing a fleet of 350 vessels and moving approximately 43 million tonnes of goods annually. Thier expertise lies in transporting various materials including dry bulk, gas, and chemicals throughout Europe.

Wattlab has been at the forefront of integrating solar technology into both inland and maritime shipping. Actually, another vessel from HGK Shipping called MS Helios made headlines recently for having the largest solar panel array on an inland cargo ship—312 panels—but it only powers low-voltage systems like lighting.

In contrast, Blue Marlin’s advanced setup integrates both low- and high-voltage systems seamlessly. David Kester, co-founder and COO of Wattlab, emphasized that this represents a groundbreaking achievement for inland shipping; it can now be officially recognized as utilizing solar energy directly for navigation.

Under ideal sunlight conditions, this system can generate up to 35 kilowatts of power while working alongside four diesel generators that support its electric propulsion system. This combination allows for “peak shaving,” where renewable energy reduces reliance on additional generators during peak demand times.

Moreover, Blue Marlin employs automated energy management to optimize power distribution based on real-time needs—enhancing efficiency while conserving fuel resources.

Wattlab notes that when sailing downstream with minimal cargo load, there are instances where Blue Marlin could operate solely on solar power—a remarkable feat previously unseen in this sector!
