    Abstract: An energy storage bridge includes a plurality of bridge girders and a bridge deck. The bridge girders include multiple steel pipes for carrying loads and storing energy in a form of compressed air contained therein and a plurality of web plates. The bridge deck is disposed on top of the bridge girders and configured for loading live loads. The steel pipes are assembled in at least a row aligned vertically. Each web plate connects a row of the steel pipes at a center line separating the steel pipes into two halves. Alternatively, a steel pipe is connected by two webs at the two sides of the pipe. Each bridge girder forms an energy storage unit between two consecutive movement joints of the energy storage bridge. Every two consecutive storage units are joined by a high pressure flexible pipe to form a giant energy storage unit. Each energy storage unit is provided with inlet and outlet pipes to in-take compressed air from electric compressors driven by the grid power or by regenerated powers, and to release the compressed air to generate electricity. The bridge girders are disposed at a predetermined transverse spacing across the width of the bridge deck and configured for supporting the bridge deck as a roadway surface.

    Abstract: A remaining gas amount calculating device includes a hydrogen tank, an opening/closing valve arranged to deliver hydrogen gas from inside the hydrogen tank, a decompression valve arranged to decompress hydrogen gas delivered from the hydrogen tank, a pressure sensor arranged to measure the pressure of hydrogen gas decompressed with the decompression valve, and a power source system controller arranged to determine the remaining gas amount in the hydrogen tank by calculating the gas pressure in the hydrogen tank based on the hydrogen gas pressure measured with the pressure sensor. The relationship between pressures in a primary chamber and a secondary chamber of the decompression valve is monotonical such that when the pressure in the primary chamber increases, the pressure in the secondary chamber also increases; and when the pressure in the primary chamber decreases, the pressure in the secondary chamber also decreases. The remaining gas amount calculating device makes it possible to calculate the amount of gas remaining in a gas container without using a gas pressure measuring device that measures directly the pressure in the gas container.
