<P>PROBLEM TO BE SOLVED: To aim at effective utilization of energy by accommodating hydrogen needed for a fuel cell system as well as power and heat generated among a plurality of users without waste. <P>SOLUTION: A hydrogen station 10 capable of generating and storing hydrogen, a fuel cell 20 capable of hydrogen power generation, and various equipment/devices of the side of the users 30a to 30n using the hydrogen, power and heat are connected to each other through a grid consisting of a hydrogen piping 2, a power transmission line 3, and a hot-water piping 4 to which the hydrogen, power and heat are supplied respectively, and flow volumes of the hydrogen, power and heat are managed and controlled at a grid management center 40 via communication lines. With this, the hydrogen used for hydrogen power generation of the fuel cell 20 and the power and the heat generated by the hydrogen power generation can be shared among the hydrogen station 10, the fuel cell 20 and the plurality of users 30a to 30n, so that the hydrogen in excess or in short supply can be stored by or supplied from the hydrogen station 10. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
