This presentation introduces the Compact Onboard DC Grid (cODCG), a next-generation power distribution system designed for short-distance shipping. As maritime industries face increasing pressure to reduce emissions and improve efficiency, cODCG offers a modular, scalable and compact solution optimized for battery electric, hybrid and fuel cell vessels. Attendees will gain insights into the system’s architecture, operational benefits and real-world applications, including a case study. The session highlights how cODCG supports compliance with IMO regulations, reduces lifecycle costs and enables a transition to zero-emission port operations – paving the way for a cleaner, smarter maritime future.
