Full Steam Ahead for Fuel Cells Sleek yachts, comfortable passenger ferries and modern naval vessels - all stand to benefit from the future use of ecological fuel cells. Up-to-date insights into the state of research are being offered by the H2Expo, a specialist conference and trade fair for hydrogen and fuel cell technologies at the end of August in Hamburg. Hydrogen is the energy carrier of the future. With its high efficiency and low ecological burden, it offers an economical alternative to conventional fuels. Small wonder that the shipbuilding industry is also in the process of rethinking, by promoting research into maritime fuel cell technology against a backdrop of increasing energy costs and ever stricter environmental regulations. Germanischer Lloyd too has been active in this field of research and development for several years now. As a founding member of the Initiative for Fuel Cells and Hydrogen Technology run by the State of Hamburg, Germanischer Lloyd is also participating in the H2Expo. Dr.Ing. Gerd-Michael Würsig, Head of the Section for Fuel Cell and Process Technology within the Advanced Engineering and Strategic Research Division of Germanischer Lloyd, is chairing a workshop on the topic "Maritime Application of Fuel Cells". "We are already expecting the first shipboard applications of fuel cells within the next ten years," is the forecast by Dr. Würsig. Power ratings of several hundred kW can be achieved today, with future output levels reaching into the MW zone. Owing to reduced CO2 emissions, this energy converter is of particular interest for ships sailing in coastal waters. Yachts, sportboats and small ferries stand to profit in the short term. However, fuel cell technology has more advantages to offer: "The low levels of noise and vibration are decisive plus points for naval ships as well as passenger, research and official vessels in ecologically sensitive waters," says Dr.-Ing. Würsig. Practical Research To plumb the potential for ship technology in a practical way and to gain operational experience at sea, Germanischer Lloyd has teamed up with the HDW subsidiary HDW Fuel Cell Systems (HFCS) to develop a demonstrator. An FC system with an output of 160 kW has been integrated into a 20-ft. container. The plant can easily be integrated into the shipboard technology of a wide range of ships. After initial tests onshore, pilot projects will be undertaken on ships in the course of 2005. The certification of the plant will take place according to the Guidelines for Fuel Cell Systems published by Germanischer Lloyd. HDW is already successful worldwide with the commercial application of fuel cells in submarines. For instance, the four new submarines of the German Navy (type U212) were equipped with FC systems. Fuel cells have long since become part of everyday work in certification. (Source: Germanischer Lloyd's publication Non Stop). Contact Dr.-Ing. GerdMichael Würsig, at firstname.lastname@example.org.
