IGCC-EPI: Decentralized concept of a highly load-flexible IGCC power plant for excess power integration

► A new concept for integration of excess power in IGCC power plants was developed. ► It consists of an electrolysis plant and a methanation process. ► Simulations of the concept in Aspen Plus show a superior operation range. ► Synergies between the processes result in a high overall storage efficiency.
