Document Type and Number:
Japanese Patent JP2019090084
Kind Code:
A
Abstract:
To provide the low carbon energy system that can efficiently suppress carbon dioxide.SOLUTION: The low carbon energy system comprises: connecting a water electrolysis apparatus 3 and methanation apparatus 4 through a hydrogen supply line 13, connecting the methanation apparatus 4 and a cogeneration system 5 through a first methane supply line 14, connecting the water electrolysis device 3 and the cogeneration system 5 through an oxygen supply line 12, connecting the cogeneration system 5 and the methanation apparatus 4 through first carbon dioxide recovery means 15, using the cogeneration system 5 to supply to the methanation apparatus 4 the carbon dioxide generated when operating using oxygen supplied from the water electrolysis apparatus 3 and methane gas supplied from the methanation apparatus 4, and using the methanation apparatus 4 to react hydrogen supplied from the water electrolysis apparatus 3 with the carbon dioxide recovered from the cogeneration system 5 for producing the methane gas.SELECTED DRAWING: Figure 1
