Can Cobalt-Graphene Beat Out Platinum As Catalyst in Hydrogen Fuel Cells?

Platinum works well as a catalyst in hydrogen fuel cells, but it is expensive and degrades over time. Brown University chemist Shouheng Sun and his students have developed a new material — a graphene sheet covered by cobalt and cobalt-oxide nanoparticles — that can catalyze the oxygen reduction reaction nearly as well as platinum does and is substantially more durable.

'Nanoflowers' for Energy Storage and Solar Cells

North Carolina State University researchers have created flower-like structures out of germanium sulfide (GeS) – a semiconductor material – that have extremely thin petals with an enormous surface area. The GeS flowers hold promise for next-generation energy storage devices and solar cells.

Harnessing the Power of Spinach

Vanderbilt University researches have developed a way to combine Photosystem 1 (PS1), the photosynthetic protein that converts light into electrochemical energy in spinach with silicon (the material used in solar cells), in a fashion that produces substantially more electrical current than has been reported by previous biohybrid solar cells.

Starting Point for Overcoming Barrier to Fusion Power

The accuracy of a new model for predicting the size of a key barrier to fusion power, which was developed by physicist Robert Goldston of the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL), has been confirmed. Goldston’s model predicts the width of what physicists call the “scrape-off layer” in tokamaks, the most widely used fusion facilities.

Promoting Virtual Power Plants for Efficient Renewable Energy Production

Researchers from the School of Electronics and Computer Science (ECS) at the University of Southampton have devised a novel method for forming virtual power plants (VPPs) to provide renewable energy production in the UK. Small and distributed energy resources (DERs), such as wind farms and solar panels, have been appearing in greater numbers in the electricity supply network (Grid).
