A novel solid oxide redox flow battery for grid energy storage

Redox Flow Battery for Energy Storage

To realize a low-carbon society, the introduction of renewable energies, such as solar or wind power, is increasingly being promoted these days worldwide. A major challenge presented by solar and wind power generators is their fluctuation in output. If they are introduced in large numbers to the power system, problems, such as voltage rises, frequency fluctuations and surplus of the generated p...

Integration of a Vanadium Redox Flow Battery with a Proton Exchange Membrane Fuel Cell as an Energy Storage System

The proton exchange membrane (PEM) fuel cell is a green energy producer which converts chemical energy to electricity in high yield. Alternatively, the vanadium redox flow battery (VRB) is one of the best rechargeable batteries because of its capability to average loads and output power sources. These two systems are modeled by Nernst equation and electrochemical rules. An effective energy gene...

Enhanced reversibility and durability of a solid oxide Fe-air redox battery by carbothermic reaction derived energy storage materials.

The recently developed solid oxide metal-air redox battery is a new technology capable of high-rate chemistry. Here we report that the performance, reversibility and stability of a solid oxide iron-air redox battery can be significantly improved by nanostructuring energy storage materials from a carbothermic reaction.

Electrical energy storage for the grid: a battery of choices.

The increasing interest in energy storage for the grid can be attributed to multiple factors, including the capital costs of managing peak demands, the investments needed for grid reliability, and the integration of renewable energy sources. Although existing energy storage is dominated by pumped hydroelectric, there is the recognition that battery systems can offer a number of high-value oppor...
