Advancing aqueous redox flow batteries through molecular engineering

E-Mail Helping to advance the potential of aqueous redox flow batteries - which could provide safe grid-scale energy storage - researchers have engineered a new class of molecules to provide energy storage for this battery type. We have demonstrated here the ability to pursue and exploit accelerated redox reactions enabled by molecular engineering of materials that would otherwise be unsuitable for flow batteries, they write. The past decade has witnessed the rapid development of redox flow batteries, which are well-suited for large-scale grid storage applications. However, suitable redox molecules, which serve as the energy storage materials for these batteries, are currently limited. Developing such molecules for flow battery applications is urgently needed to fully unleash the energy storage potential of aqueous organic redox flow batteries, write Bo Hu and T.

Compound commonly found in candles lights the way to grid-scale energy storage

E-Mail IMAGE: PNNL scientist Ruozhu Feng created a series of molecular engineering steps to cultivate fluorenone s energy-carrying capability, part of an effort at Pacific Northwest National Laboratory to develop new energy-storage technology. view more Credit: (Photo by Andrea Starr | Pacific Northwest National Laboratory) A compound used widely in candles offers promise for a much more modern energy challenge storing massive amounts of energy to be fed into the electric grid as the need arises. Scientists at the U.S. Department of Energy s Pacific Northwest National Laboratory have shown that low-cost organic compounds hold promise for storing grid energy. Common fluorenone, a bright yellow powder, was at first a reluctant participant, but with enough chemical persuasion has proven to be a potent partner for energy storage in flow battery systems, large systems that store energy for the grid.
