The invention is an Energy Storage Bridge (ESB) consisting of air-tight steel pipes, which are used to store the compressed air as stored energy, also used as the load carrying structural elements of the bridge. The stored energy can be the unwanted grid power or the intermittent regenerated energy sources. When the energy is needed, the compressed air is released to convert back to electricity, or to make use of the compressed air to produce hot water during its compression cycle, and cool air at its decompression and expansion cycle when it absorbs heat- an air conditioning technology called Air Cycle Air Conditioning (ACAC) widely used in commercial aircraft. For sea-crossing bridges, because of their great lengths the bridge body volume is enormous, and because of their remoteness from populated areas, they suit well for mass energy storage attached to power plants. With safety measures built in the steel pipes, the ESB can be applied to city road bridges. Since these bridges are not far from populated areas, they can be used as small energy storage units that provide the nearby industrial and commercial complex as well as residential buildings hot water and compressed air for air-conditioning using ACAC technology. The process eliminates the conversion of compressed air back to electricity, but directly uses the compression and decompression cycles to supply hot water and cool air for air-conditioning to the nearby consumers.
