The need for power to gas system is increasing according to the increase of power generation by renewable energy. Heat and mass balance of the coal gasification methane production system was analyzed aiming to integrate with the power to gas system which utilizes methane as a storage medium. The system converts 500 ton/day of coal to 141 ton/day of methane and conversion efficiency is 64.9% in calorie basis. Suppose surplus electricity is 10 MW, 7.8% of coal and 12.9% of oxygen can be saved by the integration. Surplus water recovered from the outlet of shift reactor and water generated with methane at the methanation reactor is recycled to the gasifier outlet to increase H_2O/CO ratio of syngas. This direct quench method contributes to reduce the plant cost because water can be recycled without water treatment.
