| Master and Commander Posts: 1893 Location: Patterson, New York | Subject: Hydrogen Boats Forever - HBF Air Products Fuels New Hydrogen Submarine for Hellenic Navy July 12, 2007: 10:51 AM EST LEHIGH VALLEY, Pa., July 12 /PRNewswire-FirstCall/ -- Air Products, in partnership with Hellas Air Pro Ltd., recently supplied a new state of the art submarine of the Hellenic Navy with hydrogen. This is the first fueling of this kind in Greece and took place in Skaramanga, near Athens. Prior to this event, Air Products had supplied the integral components of the hydrogen fueling station to Howaldtswerke -- Deutsche Werft GmbH (HDW), who owns the design of the submarine and who supplied the fueling station to Greece. The HDW Class 214 submarine has a fuel cell-generated power supply, allowing it to operate entirely on hydrogen. The fuel cell, which produces electrical energy from oxygen and hydrogen, allows the new submarine to cruise under water for weeks without resurfacing. Conventional diesel-electric submarines typically deplete their battery power after a few days cruising under water. In addition, the fuel cell makes no noise and produces no detectable exhaust heat, in turn making the submarine virtually undetectable. The fueling technology is based on Air Products' unique cryogenic hydrogen compressors (CHCs), which are used in conventional hydrogen supplies, as well as in bus fueling applications. "We are paving the way to the future hydrogen economy, by already supplying liquid hydrogen from Central Europe, as far as Ireland, Italy, Spain and Israel. By supplying liquid hydrogen as well as fueling equipment, we are able to offer a complete and safe package to our customers. We are proud to have already supplied hydrogen fueling equipment, as well as liquid hydrogen, to fuel submarines from the German Navy and now the Hellenic Navy, and we hope more will adopt this revolutionary technology soon," said Ian Williamson, general manager-Future Energy Solutions, Air Products Europe. Air Products is an industry leader in hydrogen safety and engineering, and a global leader in hydrogen production and distribution, as well as the industry leader in hydrogen fueling stations for clean transportation applications. Over the past 10 years, the company has developed over 70 hydrogen fueling installations in the United States, Korea, Singapore, Japan, Italy, Germany and India. Over 33,000 vehicle fuelings have already taken place using Air Products' technology. The submarine was built by Hellenic Shipyards S.A., part of the new North European shipyard concern ThyssenKrupp Marine Systems, who also owns HDW. Hellenic Shipyards is planning to build further fuel cell-powered submarines for the Hellenic Navy, under a HDW license. Additional contracts are in place to add plug-in fuel cell sections into conventional driven submarines. Air Products also supplies industrial gases and associated equipment to a variety of other industries, including metals processing, refining, chemical production, fat and oils production and electronics processing, as well as supplying hydrogen purification equipment. Air Products serves customers in technology, energy, healthcare and industrial markets worldwide with a unique portfolio of products, services and solutions, providing atmospheric gases, process and specialty gases, performance materials and chemical intermediates. Founded in 1940, Air Products has built leading positions in key growth markets such as semiconductor materials, refinery hydrogen, home healthcare services, natural gas liquefaction, and advanced coatings and adhesives. The company is recognized for its innovative culture, operational excellence and commitment to safety and the environment and is listed in the Dow Jones Sustainability and FTSE4Good Indices. The company has annual revenues of $9 billion, operations in over 40 countries, and over 20,000 employees around the globe. For more information, visit http://www.airproducts.com | ||

| Plankowner Posts: 5024 Location: Gulfport, MS | Subject: RE: Hydrogen Boats Forever - HBF Archerfish was tied-up in a nest of Limey boats outboard the British submarine depot ship HMS Adamant (A108) in Faslane. (Long before the days of our Nukes being there) It was still an hour or so until time for the noon meal when I wandered over to the Adamant to goof off for awhile. As I leaned on the rail on the 01 level and looked down at the boats in the nest alongside I became aware that the Limey boats were all granting early liberty. This was unusual for them as they always seemed to put in a full day’s work during the week. I asked one of the British sailors that was standing near me what was going on. He told me that "The Exploder is on the way in and whenever she enters port we all get off before she gets here." I asked "What the hell is the Exploder and why does her arrival get you early liberty?" He explained that Exploder was really HMS Explorer (S40), which was one of two experimental boats that were fueled by highly-volatile Hydrogen Peroxide (HTP), the other being Excalibur. The nickname Exploder referred to the fireballs thrown from the exhaust when the engines were started. Both boats were powered by diesel engines, electric motors, and steam turbine plants that were similar to the Walther HTP system used by the Germans in their Type XVII-B boats near the end of WW II. One of the German boats, U1407, was found scuttled in Cuxhaven in 1945. She was raised by RN occupational forces and commissioned as HMS Meteorite. HMS Explorer and Excalibur were both built by Vickers for full-scale testing of HTP as a fuel and were used as high-speed underwater targets for anti-submarine warfare training. They were among the fastest submarines in the world, but were soon rendered obsolete by the advent of nuclear power. My friend told me it was customary that whenever one of these experimental submarines entered port, all hands that weren't required to be aboard other in-port vessels were granted early liberty prior to their arrival. That sounded like a good custom to me, so I hot footed it back to the boat and presented my case to the Engineer (Miles Graham). I should have saved my breath. | ||
