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 ...

Design of a Pilot SOFC System for the Combined Production of Hydrogen and Electricity under Refueling Station Requirements

François Maréchal, Jan Van Herle, Stefan Diethelm, Alberto Mian, Maria del Mar Perez Fortes

The objective of the current work is to support the design of a pilot hydrogen and electricity producing plant that uses natural gas (or biomethane) as raw material, as a transition option towards a 100% renewable transportation system. The plant, with a s ...

Stability profiles of transition metal oxides in the oxygen evolution reaction in alkaline medium

Xile Hu, Aliki Moysiadou

The electrochemical water splitting reaction can convert renewable electricity into clean hydrogen fuel. The efficiency of water splitting is limited to a large extent by the sluggish oxygen evolution reaction (OER). Numerous transition metal oxides have b ...

Analysis of hydrogen distribution and migration in fired passivating contacts (FPC)

Christophe Ballif, Franz-Josef Haug, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Andrea Ingenito, Matthieu Despeisse, Philippe Wyss, Mario Joe Lehmann

High temperature passivating contacts for c-Si based solar cells are intensively studied because of their potential in boosting solar cell efficiency while being compatible with industrial processes at high temperatures. In this work, the hydrogenation mec ...

Transition Metal Oxides as Electrocatalysts for the Oxygen Evolution Reaction in Alkaline Solutions: An Application-Inspired Renaissance

Xile Hu, Lichen Bai, Fang Song, Laurent Liardet, Seunghwa Lee, Aliki Moysiadou, Chao Hu

Water splitting is the essential chemical reaction to enable the storage of intermittent energies such as solar and wind in the form of hydrogen fuel. The oxygen evolution reaction (OER) is often considered as the bottleneck in water splitting. Though meta ...

2018

The water-splitting reaction provides a promising mechanism to store renewable energies in the form of hydrogen fuel. The oxidation half-reaction, the oxygen evolution reaction (OER), is a complex four-electron process that constitutes an efficiency bottle ...

2018

Our current energy production is convenient and simple, but it is not sustainable. The negative impacts on our environment are omnipresent in the form of smog, extinction of species, and global warming. A major challenge of our generation is the transition ...

EPFL2018

Heterogeneous electrochemical phenomena, such as (photo)electrochemical water splitting to generate hydrogen using semiconductors and/or electrocatalysts, are driven by the accumulated charge carriers and thus the interfacial electrochemical potential grad ...
