Heat transfer modeling in integrated photoelectrochemical hydrogen generators using concentrated irradiation

Sophia Haussener, Saurabh Yuvraj Tembhurne, Mikaël Dumortier

The direct conversion of solar energy and water into a storable fuel via integrated photoelectrochemical (PEC) devices is investigated. Particularly, the proposed device uses concentrated solar irradiation in order to minimize the amount of rare and expens ...

Renewable hydrogen generation from a dual-circuit redox flow battery

Hubert Girault, Christos Comninellis, Xile Hu, Heron Vrubel, Véronique Amstutz, Kathryn Ellen Toghill, Francis Powlesland

Redox flow batteries (RFBs) are particularly well suited for storing the intermittent excess supply of renewable electricity; so-called “junk” electricity. Conventional RFBs are charged and discharged electrochemically, with electricity stored as chemical ...

Formation of an electron hole doped film in the alpha-Fe2O3 photoanode upon electrochemical oxidation

Michael Graetzel, Artur Braun, Florent Alexandre Boudoire

Solar hydrogen generation by water splitting in photoelectrochemical cells (PEC) is an appealing technology for a future hydrogen economy. Hematite is a prospective photoanode material in this respect because of its visible light conjugated band gap, its c ...

Evidence for hydrogen generation in laser- or spark-induced cavitation bubbles

Mohamed Farhat, Marc Tinguely

The growing use of focused lasers or electric sparks to generate cavitation bubbles raises concerns about the possible alteration of gas content during the initiation process and its effect on bubble dynamics. We provide experimental evidence that hydrogen ...
