New Flow Battery to Keep Big Cities Lit, Green & Safe

View | Comment

The new zinc-polyiodide redox flow battery uses an electrolyte that has more than two times the energy density of the next-best flow battery used to store renewable energy and support the power grid. It’s high energy density, and resulting lower cost, make it ideal for large cities where space is at a premium.

JRSE-Bensalah-algorithm-corrected.jpg

A group of researchers in Tunisia and Algeria show how fuzzy logic has helped them create an ideal photovoltaic system that obeys the supply-and-demand principle and its delicate balance. They describe this new sizing system of a solar array and a battery in a standalone photovoltaic system in The Journal of Renewable and Sustainable Energy.

University of Utah scientists captured enough data on crucial steps in a chemical reaction to accurately predict the structures of the most efficient catalysts, those that would speed the process with the least amount of unwanted byproducts. The new approach could help chemists design catalysts that are not just incrementally better, but entirely new.
