Costa Diadema Starts Using Shore Power in Kiel


On June 7th, Costa Diadema, a Costa Cruises ship, successfully connected to the electrical grid available at the Ostuferhafen cruise terminal in the port of Kiel for the first time. It will continue to do so for all scheduled stops until the end of summer.

By using shore power, the ship was able to shut down its engines, thereby reducing direct atmospheric emissions. This is an important step for the company, which is constantly working to improve the environmental performance of its ships both during navigation and while docked in ports.

This milestone was also achieved thanks to the collaboration with the port of Kiel, which will be a very important port for Costa’s Northern European operations in 2024. From May 10th to September 19th, Costa Diadema will visit Kiel every Friday on a week-long itinerary exploring the Norwegian fjords, always docking at the Ostuferhafen cruise terminal, located outside the city center of Kiel.

To continuously improve the environmental performance of its fleet, the company is supported by the Decarbonisation Department of Carnival Maritime, created specifically to develop and test new technologies to reduce environmental impact. These include an innovative lithium-ion battery system; air lubrication systems in the hull to reduce resistance and thus fuel consumption; methanol-fueled fuel cells; new methods for carbon capture and storage; and alternative low-carbon fuels such as bio-LNG or liquefied biomethane.

Costa Crociere aims to operate a net-zero greenhouse gas emission fleet by 2050. The company is working to further enhance the energy efficiency of its existing ships and to support innovation in port infrastructure. Key actions to achieve this goal include the introduction of Costa Toscana and Costa Smeralda, the first LNG-powered ships; the commitment to equip its fleet with shore power connections and to work closely with port authorities to promote wider adoption of this technology; the introduction of advanced air quality systems (AAQS) on non-LNG ships to reduce emissions in port and at sea; route redesign to reduce fuel consumption, and much more.
