Offshore Supply Vessel Coastal Liberty, operating in the German Wadden Sea, has transitioned to using green hydrogen as its main source of energy, achieving a significant milestone in sustainability. The vessel received class certification in February 2024 for its hydrogen system installed by eCap Marine, which includes fuel cells, a battery system, and safety equipment. The hydrogen is produced locally using offshore wind power, with a focus on safety during transport and usage. The system not only reduces emissions but also improves crew comfort and propulsion efficiency. eCap Marine believes that this investment will benefit customers, society, and the environment in the long run, showcasing a commitment to green energy and innovation in the maritime industry.
