A techno-economic assessment of implementing power-to-gas systems based on biomethanation in an operating waste water treatment plant

The aim of the present study is to assess techno-economic viability integrating biomethanation into power gas systems in a real waste water treatment plant (WWTP). research first attempt several scenarios based on technology that include both in- and ex-situ as well utilisation on-site renewable electricity grid transient mode. Five were designed evaluated calculated LCOE lies between 127.8 159.8 £/MWh. consideration existing policy mechanisms revenues from by-products reduces LCOEs 31.4–68.1 execution sensitivity analysis exposed price electrolyser cost are main contributors all scenarios. Future advances along with imposing appropriate incentives can create proper framework for two generate profits. concludes current future application should focus utilising generated electricity.
