Abstract:
1. A renewable energy storage system for storing renewable energy, comprising: electrical power generator converting the renewable energy into an electrical power; energy storing device storing the electrical power; hydrogen producing device producing hydrogen, using the electrical power obtained by the electrical power generator and/or the electrical power stored by the energy storing device; hydrogenating device for adding the hydrogen produced by the hydrogen producing device to unsaturated hydrocarbon; saturated hydrocarbon storing device for storing saturated hydrocarbon produced by adding the hydrogen to the unsaturated hydrocarbon; unsaturated hydrocarbon storing device for storing the unsaturated hydrocarbon; unsaturated hydrocarbon supply amount controller for controlling an amount of the unsaturated hydrocarbon that is stored in the unsaturated hydrocarbon storing device and is to be supplied to the hydrogenating device; output voltage detector detecting an output voltage value of the electrical power generator; charge voltage detector detecting a charge of voltage value of the energy storing device; and electrical current detector detecting an electrical current amount supplied to a hydrogen producing detector, wherein an amount of hydrogen produced by the hydrogen producing device is estimated based on detected output voltage value, detected charge voltage value, and detected electrical current amount, and wherein the supply amount controller controls the amount of the unsaturated hydrocarbon to be supplied to the hydrogenating device based on the estimated amount of hydrogen.
