Trade-off designs of power-to-methane systems via solid-oxide electrolyzer and the application to biogas upgrading

François Maréchal, Jan Van Herle, Stefan Diethelm, Ligang Wang, Guillaume Jeanmonod

Solid-oxide electrolyzer based power-to-methane is promising for large-scale energy storage as well as biogas upgrading by efficiently converting intermittent renewable power and CO2 (e.g., in biogas) into synthetic methane. Either air or pure oxygen can b ...

A Cogeneration System Based on Solid Oxide and Proton Exchange Membrane Fuel Cells With Hybrid Storage for Off-Grid Applications

François Maréchal, Ligang Wang, Francesco Baldi, Maria del Mar Perez Fortes

Solid oxide fuel cells (SOFC) have developed to a mature technology, able to achieve electrical efficiencies beyond 60%. This makes them particularly suitable for off-grid applications, where SOFCs can supply both electricity and heat at high efficiency. C ...

Power-to-fuels via solid-oxide electrolyzer: Operating window and techno-economics

François Maréchal, Jan Van Herle, Stefan Diethelm, Ligang Wang, Tzu-En Lin

Power-to-fuel systems via solid-oxide electrolysis are promising for storing excess renewable electricity by efficient electrolysis of steam (or co-electrolysis of steam and CO2) into hydrogen (or syngas), which can be further converted into synthetic fuel ...

Balancing wind-power fluctuation via onsite storage under uncertainty: Power-to-hydrogen-to-power versus lithium battery

François Maréchal, Jan Van Herle, Ligang Wang, Yumeng Zhang

Imbalance costs caused by forecasting errors are considerable for grid-connected wind farms. In order to reduce such costs, two onsite storage technologies, i.e., power-to-hydrogen-to-power and lithium battery, are investigated considering 14 uncertain tec ...
