A hydrogen system includes: a generator which generates hydrogen-containing gas; a storage which stores the hydrogen-containing gas generated by the generator; a first gas passage which connects the generator and the storage; a housing which houses the generator, the storage and the first gas passage; a second gas passage in which the hydrogen-containing gas discharged from the first gas passage to an outside of the housing flows; a first valve provided to the second gas passage; a third gas passage in which the hydrogen-containing gas discharged from the storage to the outside of the housing flows; a second valve provided to the third gas passage; and a controller which opens at least one of the first valve and the second valve.

Hydrogen system

A hydrogen system including: a hydrogen production apparatus that produces hydrogen; a hydrogen storage apparatus that stores produced hydrogen; a first flow path, wherein hydrogen discharged from the hydrogen production apparatus flows into the hydrogen storage apparatus through the first flow path; a second flow path, wherein hydrogen discharged from the hydrogen storage apparatus flows into a hydrogen-using apparatus through the second flow path; a casing that houses the hydrogen production apparatus, the hydrogen storage apparatus, the first flow path and at least part of the second flow path; a third flow path, wherein hydrogen discharged from at least one of the hydrogen production apparatus, the hydrogen storage apparatus, the first flow path and the at least part of the second flow path flows outside the casing through the third flow path; a first valve provided in the third flow path; and a controller that opens the first valve.

A power system includes: a storage battery; a water electrolyzer; a fuel cell that generates electricity using hydrogen supplied from a hydrogen reservoir that stores hydrogen generated by the water electrolyzer; a detector that detects whether there is a person in a building; and a controller that performs at least one of first control and second control. The first control determines a priority between the storage battery and the water electrolyzer, to which electric power is supplied from a power generation device using renewable energy, based on information detected by the detector. The second control determines a priority between the storage battery and the fuel cell, from which electric power is supplied to a power load provided in the building, based on the information detected by the detector.

Power system

A power supply system includes: a hydrogen generation device that uses electric power to generate hydrogen; a hydrogen storage device that stores hydrogen generated by the hydrogen generation device; a fuel cell system that uses hydrogen stored in the hydrogen storage device to generate electric power; a power storage device; and a control device executing at least one of first control and second control based on an electricity expense, the first control controlling a first ratio between electric power to be supplied from a natural energy power generation device to the hydrogen generation device and electric power to be supplied from the natural energy power generation device to the power storage device, the second control controlling a second ratio between electric power to be supplied from the power storage device to a load and electric power to be supplied from the fuel cell system to the load.

Power supply system and method of controlling the same

There is provided a power supply system in which a user can easily determine an optimum method of consuming power obtained by discharging a power storage portion. The power supply system () includes: a power storage portion () that supplies a power by discharge; a dischargeable time prediction portion () that predicts, when a power is supplied to a predetermined load among a plurality of loads included in the load portion (), a dischargeable time that is a time period in which the power storage portion () can perform discharge; and a notification portion () that notifies a user of the dischargeable time predicted by the dischargeable time prediction portion (). The dischargeable time prediction portion () predicts a plurality of dischargeable times in which combinations of loads receiving power supply are different and the notification portion () notifies the dischargeable times.

Power supply system

[Problem] To provide a charging system that levels the amount of grid power that is used, and that is capable of reducing power rates, even if charging has been frequently conducted without limiting the time zones in which charging is conducted. [Solution] A charging system is provided with: a storage unit that is charged by consuming grid power supplied by a power company, and that supplies the stored power through discharge; and a charging unit that charges batteries by consuming power supplied by grid power and the storage unit. Power companies set a power rate that is higher the greater the maximum value of the amount of power supplied for each unit of time is. Furthermore, at least a single charge carried out by the charging unit is carried out over two units of time, and the storage unit supplies power to the charging unit in at least one unit of time other than said two units of time.

Charging system

A power supply system is provided that can reduce the maximum value of the amount of power per unit time supplied to a load and a power storage portion and that can increase the amount of power stored in the power storage portion. The power supply system () includes the power storage portion () and a charge-discharge control portion () that controls the charge and discharge of the power storage portion (). The power supply system () supplies power to an EV charge portion () that is one of power storage portions (). The charge-discharge control portion () charges the power storage portion () when a power or a current consumed by the EV charge portion () is equal to or less than a predetermined magnitude.

Power supply system with controlled power storage

Disclosed is a power supply device which acquires data of the amount of environmental load material emitted from a power supply, and controls operations on the basis of the data.

Power supply device, power storage device, and power control device

A Coriolis mass flow meter targeted for measurement of a fluid with a minute flow rate is reduced in weight and size, the flow meter being in which a subframe supporting a vibration exciter and first and second detectors has an outer peripheral wall, a notch and an inner peripheral wall, a circuit board supported by a main frame is positioned in the portion of the notch, the circuit board is housed in a board case penetrating the main frame, and a liquid crystal monitor is mounted in the portion of the circuit board adjacent to supply/discharge portions of a pair of vibration tubes.

Coriolis mass flow meter having a support frame installed between the pair of vibrating tubes

A flowmeter of Coriolis type includes a supporting base that supports a pair of fluid pipes in a manner capable of being vibrated, and a frame fixed to the supporting base. The frame is integrally formed with a mounting portion disposed between the fluid pipes and having a thickness that does not interfere with the fluid pipes, a reinforcing portion disposed at the outer circumference of the mounting portion and enhancing the rigidity of the mounting portion, and a fixing portion for being fixed to the supporting base. The reinforcing portion has an outer wall portion that protrudes at least to one side of the thickness direction of the mounting portion, and substantially continuously surrounds the outer circumference of the fluid pipes. Penetrating portions for disposing the coils corresponding to respective magnetic substances mounted on the fluid pipe are formed in the mounting portion.
