The permanent magnet type electrical rotating machine has an overhung rotor support structure in which a shaft of a rotor is supported at only one end side thereof by a bearing provided on one side of a casing of the electrical rotating machine. Another end side of the rotor shaft to be a bearing support-free side is capable of being joined to an end of a shaft of a prime mover via a flange formed at an end of the shaft. The rotor shaft is configured such that, upon a state of not being coupled to the prime mover shaft, the flange on the bearing support-free side is joined to an end face of the casing through a retaining member to be prevented from moving in any of an axial, radial and circumferential directions of the rotor shaft.

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.

An organic hydride reactor generates hydrogen by electrolyzing electrolyte to manufacture the organic hydride from the generated hydrogen. The system has a anode and cathode opposed to each other, the electrolyte supplied between the anode and cathode, a hydrogenation catalyst performing hydrogenation reaction between the hydrogen supplied from the anode by electrolysis and organic compound. The anode cathode has gas-fluid separation function and the electrolyte is supplied to only one surface of the anode and cathode, and a gas caused by electrolysis is discharged from a surface not being in contact with the electrolyte of the anode and cathode.

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.
