Dutch marine solar developer Wattlab has supplied a solar energy system for HGK Shipping’s inland cargo ship, The Blue Marlin, marking a milestone in maritime sustainability. This vessel is the world’s first hybrid solar-powered inland transport ship, featuring 192 solar panels that power both its high-voltage propulsion system and onboard operations.
Wattlab, known for its solar solutions in the maritime sector, previously collaborated with HGK on the MS Helios, which boasts the largest solar panel installation on an inland vessel. However, The Blue Marlin advances this technology by fully integrating solar power into its propulsion system, rather than just serving low-voltage needs.
This hybrid configuration enables automated energy management and peak shaving, significantly reducing fuel consumption by avoiding unnecessary generator starts during peak demand. With a fleet of over 350 vessels and annual freight volumes of around 43 million tonnes, HGK Shipping plays a crucial role in Europe’s inland transport sector. Their commitment to renewable technology reflects a significant shift in an industry increasingly pressured to reduce emissions and enhance fuel efficiency.
