Outline

Methane is known as the candidate for the energy carrier. It is produced by the reduction of the carbon dioxide by hydrogen. The reaction generally requests high temperature over 350℃, which is recognized as an issue for the commercially practical applications. To solve the problem, we will reduce the methanation reaction temperature by greater than 200℃. Combining the water electrolysis over 100℃ with the methanation process, we shall realize the production process of energy carrier where 22-36% of energy consumption from the renewable energy is saved.
