A refuse vehicle includes tractive elements, a prime mover, and an independent accessory system. The prime mover is configured to generate mechanical energy to drive one or more of the tractive elements. The independent accessory system includes one or more storage tanks, an accessory primary mover, and a hydraulic pump. The one or more storage tanks are configured to store a fuel. The accessory primary mover configured to fluidly couple with the one or more storage tanks to receive the fuel from the one or more storage tanks.
