4. 3. Power-to-X-to-Power in Combined Cycle Power Plants : A Techno-Economic Feasibility Study

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Linus Engstam; [2021]
   Nyckelord :Power­to­X­to­power; Hydrogen; Ammonia; Combined cycle gas turbines; PEM electrolyzer; Technoeconomic analysis; Power­to­X­to­power; Vätgas; Ammoniak; Gasturbiner; PEM elektrolysator; Teknoekonomisk analys;

   Sammanfattning : To support the large­scale integration of renewables in electricity grids, power­to­X­to­power (P2X2P) systems have been proposed. These systems serve to increase the flexibility of thermal power plants while potentially providing both economic and environmental benefits by allowing power from the plant to be redirected into an electrolyzer and converted to a gaseous energy carrier.
