  • Meet the Blue Marlin: the world's first hybrid solar-powered inland vessel, revolutionizing shipping with 192 solar panels and cutting-edge energy efficiency.

Dutch maritime solar firm Wattlab and HGK Shipping have launched the Blue Marlin, the world's first hybrid solar-powered inland shipping vessel. Equipped with 192 solar panels, the Blue Marlin uses solar energy for both onboard systems and high-voltage propulsion, marking a significant advancement from their previous collaboration on the MS Helios, which only powered low-voltage systems.

The Blue Marlin's solar system can deliver up to 35 kW, working alongside four diesel generators to reduce reliance on additional generators during high-demand periods. The vessel, built at De Gerlien van Tiem shipyard, can operate solely on solar power for limited durations.

How does the Blue Marlin enhance solar power usage in inland shipping vessels?

  • The Blue Marlin's solar panels are strategically placed to maximize sunlight exposure, enhancing energy efficiency.
  • The integration of solar power reduces fuel consumption, leading to lower operational costs and decreased carbon emissions.
  • The vessel's hybrid system allows for seamless transition between solar and diesel power, optimizing energy use based on availability and demand.
  • The solar power system contributes to quieter operations, minimizing noise pollution in inland waterways.
  • The Blue Marlin serves as a model for future sustainable shipping solutions, encouraging the adoption of renewable energy in the maritime industry.
  • The vessel's ability to operate on solar power alone for limited periods demonstrates the potential for fully solar-powered shipping in the future.
  • The use of solar energy for high-voltage propulsion represents a technological advancement, increasing the vessel's overall energy efficiency.
  • The Blue Marlin's design and technology can be adapted for other types of vessels, promoting wider use of solar power in shipping.
