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 ...

Life cycle assessment of power-to-gas applications via co-electrolysis of CO2 and H2O

Ligang Wang

Solid-oxide electrolysis technology (SOEC) can efficiently convert electricity from renewable sources into H-2 via steam electrolysis, or syngas (a mixture of H-2 and CO2) via co-electrolysis of steam and CO2. Co-SOEC provides the advantage of better therm ...

In situ Control of the Adsorption Species in CO2 Hydrogenation: Determination of Intermediates and Byproducts

Andreas Züttel, Ligang Wang, Kun Zhao, Emanuele Moioli, Marco Calizzi

CO2 hydrogenation over catalysts is a potentially exciting method to produce fuels while closing the CO2 cycle and mitigating global warming. The mechanism of this process has been controversial due to the difficulty in clearly identifying the species pres ...

A Review: Electrochemical Biosensors for Oral Cancer

Hubert Girault, Ligang Wang, Tzu-En Lin, Sorour Darvishi

Oral cancer poses a serious threat worldwide owing to its soaring case-fatality rate and its metastatic characteristics of spreading to the other parts of the body. Despite the recent breakthroughs in biomedical sciences, the detection of oral cancer at an ...

Techno-economic optimization of biomass-to-methanol with solid-oxide electrolyzer

François Maréchal, Jan Van Herle, Ligang Wang, Maria del Mar Perez Fortes

The purpose of this paper is to assess techno-economically the integration of solid-oxide electrolysis in biomass-to-methanol processes: (1) The hydrogen produced by electrolysis can be used to adjust the composition of syngas from gasification to increase ...

A data-driven model for the air-cooling condenser of large-scale coal-fired power plants based on data reconciliation and support vector regression

François Maréchal, Ligang Wang, Ivan Daniel Kantor, Jean-Loup Sylvain Robineau

The performance of a direct air-cooling condenser under operation is rather complicated, as it is interactively affected by the operating conditions (e.g., the mode of air fans) and ambient conditions (e.g., temperature and wind speed). To understand the c ...
