Offshore Supply Vessel Coastal Liberty has embarked on a sustainable journey by implementing a green hydrogen power system, aiming to reduce its environmental footprint. The vessel, now equipped with a hydrogen-electric power system developed by eCap Marine, operates without emissions, thanks to the utilization of fuel cells and a maritime battery system. Local green hydrogen production, powered by offshore wind, ensures sustainability and safety in handling and transport. The system, which includes fuel cells, a battery system, and safety equipment, offers benefits such as reduced vibrations on board and direct propulsion. Moreover, the scalability of the system allows for potential application in larger commercial ships. The vessel's new technology marks a significant milestone in the maritime energy transition in Europe. eCap Marine believes that this investment not only benefits the environment but also promises long-term advantages for customers and society as a whole.
