Abstract
A method and apparatus for storing and transporting energy in the form of compressed air energy via a pipeline shown. The method preferably consists of using at least one power source to drive a compressor to compress air into storage, wherein the pipeline can be adapted to reduce the pressure losses that are experienced along its length, such as by providing first and second segments, wherein the second segment is located further downstream from the first segment, and the first segment's diameter is greater than that of the second segment. Facilities or communities connected to the pipeline can use the energy in the form of electricity, or to drive pneumatic tools or equipment, or to generate chilled air as a by-product, which can be used for refrigeration, air conditioning or desalination. A utility or grid or wind farm or other power source can be used to generate the compressed air energy, such as during low demand periods, such that the energy can be used during high demand periods.
