The present invention provides an improved kinetic energy recovery and/or storage system for vehicles or other devices employing kinetic energy recovery systems comprising a flywheel supported for rotation in a first vacuum enclosure for receiving energy from and dissipating energy to one or more parts of a vehicle; a scroll vacuum pumping arrangement having an inlet arranged to be in fluid communication with an outlet of the first vacuum enclosure for evacuating the first vacuum enclosure; and a second vacuum enclosure having an inlet in fluid communication with an exhaust of the scroll pumping arrangement and arranged to be maintained at a pressure less than atmosphere for reducing the pressure at the exhaust of the scroll pumping arrangement, wherein the second vacuum enclosure comprising an outlet through which gas can be pumped periodically for maintaining the second vacuum enclosure at a pressure less than atmosphere.
