When the AC line (11) of one local system (10A) and a power system (1) are in the parallel-off state, a control device (C) included in a power supply system (S) causes the local inverter devices (13) of the local systems (10) to operate in a parallel-off operation mode in which control is performed such that the voltage of power on the AC line (11) is at a target voltage and such that the frequency of power on the AC line (11) is at a target frequency determined according to the state of charge of a power storage device (12). When a condition for switching to the connected state has been satisfied, the control device (C) stops operation of the local inverter device (13) in the parallel-off operation mode and causes a switch to the connected state by operating the interrupting device (2), and thereafter causes the local inverter device (13) to operate in a charging operation mode used in charging the power storage device (12) with supplementary power received from the power system (1).

A method for hydrogen production by pressure swing adsorption that can increase the recovery efficiency of an adsorption target component while enabling an off-gas to be appropriately supplied to a combustion device is provided that can achieve a cost reduction and an increase in the efficiency of the combustion operation.


For implementing a reforming reaction such as steam reforming or autothermal reforming, to obtain hydrogen, carbon monoxide, carbon dioxide, methane, etc. by bringing hydrocarbons and steam into contact with a reforming catalyst, an arrangement is provided to enable reforming of the hydrocarbon to proceed under a stable condition for an extended period thanks to high sulfur resistance thereof. The arrangement employs a reforming catalyst supporting both platinum and iridium on an inorganic oxide support for the reforming of the hydrocarbon.


Provided is a granular activated carbon having many mesopores that can be used for applications similar to zinc chloride-activated carbons, and also provided is a method for manufacturing the same. The granular activated carbon is obtained by bringing an activated carbon into contact with a calcium component, followed by activation and washing.

A power consumption mode guiding device (30) is provided in a local system (10) in which the frequency of power on an AC line (11), to which a power consumption device (14) and a power storage device (12) are connected, is controlled so as to be at a target frequency determined according to the state of charge of the power storage device. The power consumption mode guiding device (30) includes a frequency detection unit (31) that detects the actual frequency of power on the AC line (11), an information storage unit (32) in which pieces of guidance information for guiding the mode of use of the power consumption device (14) by a power consumer (D) to a prescribed mode are stored in advance in association with pieces of frequency information obtained from detection results from the frequency detection unit (31), and a guidance information output unit (34) that reads out, from the information storage unit (32), the piece of guidance information that is associated with the piece of frequency information obtained from the detection result from the frequency detection unit (31), and outputs the piece of guidance information to the power consumer (D).


Provided is a granular activated carbon having many mesopores that can be used for applications similar to sine chloride-activated carbons, and also provided is a method for manufacturing the same. The granular activated carbon is obtained by bringing an activated carbon into contact with a calcium component, followed by activation and washing.
