Each one costs hundreds of thousands of US dollars.Tapestryhttps://www.blogger.com/profile/17267094484651413428noreply@blogger.comtag:blogger.com,1999:blog-30136383.post-48769571616449621792007-12-22T21:53:00.000+00:002007-12-22T21:53:00.000+00:00My sources tell me that the only economic way to d...My sources tell me that the only economic way to deliver and ship hydrogen around is as Ammonia, which has the formula NH3. It is a dense gas, and is produced on an industrial scale and is delivered everywhere.<BR/><BR/>Inside the vehicle it is 'cracked' by heating it up. The hydrogen splits from the nitrogen and they instantly separate with hydrogen rising to the ceiling of the chamber.<BR/><BR/>The problem is the pumping from the bulk storage into the vehicle's fuel tank. NH3 is a highly pungent gas and even a drop spilled would cause personnel to evacuate. Ammonia pumping systems are being worked on by vehicle manufacturers and by oil companies, so that ammonia can be delivered successfully.<BR/><BR/>If this problem was solved, there is a viable fuel supply route.<BR/><BR/>But the fuel cells only last about one year in continuous operation before they degrade. That is not yet long enough for the lifetime of the vehicles.Tapestryhttps://www.blogger.com/profile/17267094484651413428noreply@blogger.comtag:blogger.com,1999:blog-30136383.post-21542944586120846132007-12-22T20:15:00.000+00:002007-12-22T20:15:00.000+00:00Part of my work is with a company that uses hydrog...Part of my work is with a company that uses hydrogen as part of its process. It uses tankersful of the stuff. These days the tankers come from the continent, as the suppliers have shut down the last remaining UK supply. I hope that Uncle Ken has factored in the use of diesel to get the hydrogen from Rotterdam or wherever else it comes from! And you don't get much hydrogen in a tanker, most of the space is fresh air between the cylinders.Anonymousnoreply@blogger.com
