Patent number: 7824625Abstract: A dehydrogenation fuel theft prevention system for preventing the theft of dehydrogenation organic fuel containing hydrogen is provided. The dehydrogenation fuel theft prevention system is for systems including a reformer for dehydrogenating organic fuel containing at least hydrogen and a dehydrogenation fuel recovery tank for storing dehydrogenation fuel produced when organic fuel is dehydrogenated in the reformer. The theft prevention system is provided with a means for mixing an odorant as a component with a pungent odor other than the fuel components or a agent for coagulating the fuel components. The odorant or the coagulating agent is mixed when fuel is manufactured, distributed, utilized, recovered, or stored or fuel is about to be stolen.Type: GrantFiled: February 18, 2009Date of Patent: November 2, 2010Assignee: Hitachi, Ltd.Inventors: Masafumi Nojima, Akiyoshi Komura, Takao Ishikawa, Kenichi Souma, Masatoshi Sugimasa, Naoki Yoshimoto

Patent number: 7805271Abstract: The object of the present invention provides an evaluation system for evaluating accurately emission amount of environmental influence substance of fuel in a fuel supply facility for supplying stored fuel to a consumer. An evaluation system evaluates the emission amount of environmental influence substance of fuel in which the environmental properties (greenhouse gas emissions) accumulated in the process of drilling a first energy, transporting and storing, producing fuel, and supplying the fuel are taken into account. The evaluation system enables to present the environmental properties of the sold fuel to the fuel consumer and allows the fuel consumer to select, thereby promoting the reduction of emission amount of the greenhouse gas of the fuel supplier and the fuel consumer.Type: GrantFiled: February 20, 2008Date of Patent: September 28, 2010Assignee: Hitachi, Ltd.Inventors: Masafumi Nojima, Akiyoshi Komura, Takeyuki Itabashi, Sunao Funakoshi, Hiroshi Arita, Yukinobu Maruyama, Youichi Horii, Takao Ishikawa
