A system and method for storing nitrogen-enriched air (NEA) comprising an air separation device (ASM) and producing NEA in the ASM. One example implementation may include bleed air being supplied to a pressure intensifier. The pressure intensifier is powered by NEA compressed by a first compressor, and the pressure of the bleed air is increased by the pressure intensifier and supplied to an ASM. In another example implementation, a turbine may be drivingly connected to a second compressor and the bleed air supplied to the second compressor. The NEA compressed by the first compressor is supplied to and drives the turbine, which drives the second compressor, and the air compressed by the second compressor is supplied to the ASM. In another example implementation, a turbine may drive an electric generator, which in turn may power an electric motor that drives the second compressor.
