ENERGY INDEPENDENCE SYSTEM USING PURE OXYGEN COMBUSTION POWER GENERATION AND NEW RENEWABLE ENERGY

摘要

The present invention relates to an energy independence system using pure oxygen combustion power generation to increase an energy independence level and new/renewable energy. More specifically, according to the present invention, the energy independence system comprises: a fuel supply unit supplying a low grade fuel; a low grade fuel power generation unit performing pyrolysis by using the low grade fuel supplied through the fuel supply unit as an energy source to generate electricity; a new/renewable energy unit producing electricity through new/renewable energy; a water electrolysis unit using the electricity produced through the new/renewable energy unit to water electrolysis to separate water into hydrogen and oxygen; a pure oxygen supply unit supplying pure oxygen from the water electrolysis unit or the outside to reduce a pollution source during power generation of the low grade fuel power generation unit; a methanation unit performing methanation which couples carbon monoxide or dioxide produced through the low grade fuel power generation unit to the hydrogen separated through the water electrolysis to produce methane; and a methane processing unit capturing the methane produced through the methanation unit to store or transfer the same to the outside.
