Abstract (en)
[origin: EP2650401A1] Power station-based methanation system (1) comprises a fossil fuel-fired power station (2) with an electrolysis unit (3), and a methanation reactor (4). The power station and the electrolysis unit are designed to supply the methanation reactor with starting materials for a methanation reaction, and the electrolysis unit is operated in a charging state and a discharging state, where an electric power is supplied to the electrolysis unit and a chemical energy store is charged at the same time, during the charging state and the chemical energy store is discharged during the discharging state. An independent claim is also included for operating the methanation system, comprising either: supplying water to the electrolysis unit, electrolytically or chemically converting the water into hydrogen, mixing hydrogen with the carbon dioxide obtained from power station, and supplying the mixture of hydrogen and carbon dioxide as starting materials to the methanation reactor; or supplying a mixture of water and carbon dioxide obtained from the power plant, electrolytically or chemically converting mixture of water and carbon dioxide into hydrogen and carbon monoxide, and supplying the mixture of hydrogen with carbon monoxide as starting materials to the methanation reactor.
