The ship naming ceremony of the research vessel CORIOLIS, led by Karin Prien, Schleswig-Holstein’s Minister of Science, marked a significant event in advancing coastal, hydrogen, and membrane research. The ship, designed as a multi-purpose laboratory, represents a crucial step toward environmentally friendly maritime technology focusing on environmental protection and climate sensitivity. The vessel's innovative propulsion system is powered by electric motors driven by various generators, including a hydrogen fuel cell. Hereon developed a metal hydride tank for hydrogen storage, allowing real-world testing of hydrogen technologies. The ship utilizes membrane technology to reduce nitrogen oxide emissions by up to 80 percent. The CORIOLIS plays a vital role in coastal and climate research, studying carbon cycles, pollutant transport, and the impact of offshore wind energy in the North and Baltic Seas. Real-time data collection enables data exchange with other vessels and stations, contributing to climate change mitigation and coastal adaptation efforts. The vessel also contributes to the development of digital twins of the North and Baltic Seas, enhancing understanding of complex environmental processes and technologies. With a length of approximately 30 meters, the ship is well-suited for sampling in shallow coastal waters, accommodating 12 scientists and 3 crew members. Scheduled for 200 research days per year, the vessel's costs amount to 18 million Euros, with a notable contribution of 1.5 million for the hydrogen system laboratory. The ship, primarily funded by federal funds, is set to begin trial runs in early 2025, showcasing its innovative technologies and research capabilities. The significance of the CORIOLIS project was highlighted by Dr. Jens Meywerk, emphasizing its technical complexity and uniqueness. The vessel's christening was celebrated by guests from politics, science, and business, acknowledging its contribution to advancing coastal research and environmental protection. The interdisciplinary nature of the research conducted on CORIOLIS sets the stage for pioneering advancements in propulsion technologies, hydrogen storage, and membrane technology, positioning the vessel as a cornerstone in sustainable maritime research and environmental protection.
