Abstract: A combined heat and power microgrid system is provided that stores energy in the form of compressed air that can then be utilized as needed in the form of electricity. The compressed air may be generated with energy from multiple electrical energy sources, such as renewable energy sources. The energy stored as compressed air/heat is used to charge a battery by utilizing a pulley system and a barrel housing that transfers kinetic energy generated by the release of the compressed air to an array of piezoelectric generators that can produce electricity, which is stored in the second battery. In addition, water may be extracted from the compressed air storage tank. In this way, energy produced by the renewable sources can be accessed during periods of high need or low production and water may be collected.

Abstract: Disclosed is a compact portable compressed air energy storage (CAES) system that works with renewable energy sources and utilizes batteries to store energies instead of using turbine generators to store energies like traditional CAES systems. The compressed air source can be utilized to apply kinetic pressure to a series of linear or magnetic induction generators to produce energy and store the electricity for end users, enabling the device to function as a portable generator and power station. Its design allows it to apply a fraction of the accumulated energy to generate compressed air with sufficient pressure to trigger a series of novel generators. The isothermic portable design, instead of traditional diabatic design with heat exhausts, makes it appropriate for multiple applications, including handheld power, home power, regional power, and EV-to-grid.
