The invention relates to the technical field of energy storage systems, and discloses a port distributed efficient energy recovery system which comprises a loading and unloading crane, a lithium ion capacitor, a chemical battery pack and a power grid system. The loading and unloading crane is provided with a first generator motor; the lithium ion capacitor and the chemical battery pack are electrically connected with the first generator motor, the lithium ion capacitor is used for supplying power to the first generator motor in the starting stage and recycling electric quantity generated by the first generator motor, and the chemical battery pack is used for supplying power to the first generator motor in the operation stage. Recycling electric quantity generated by the first generator motor and storing surplus electric quantity of the new energy power station; in the lifting state, at least one of the lithium ion capacitor, the chemical battery pack and the new energy power station supplies power to the firs
