A fuel cell might be considered as a type of flow battery in that the power conversion component is independent of the chemical energy capacity of the device. Most fuel cells involve oxygen at the positive electrode, and cannot be reversed electrically efficiently, and consequently cannot be used effectively as an electrical energy-storage device.
Flow batteries and regenerative fuel cells have the potential to play a pivotal role in this transformation by enabling greater integration of variable renewable generation and providing resilient, grid-scale energy storage.
Rather than viewing flow batteries as a replacement for fossil fuels, we should see them as a valuable addition to our energy portfolio. A diversified energy mix that includes coal, natural gas, renewables, and advanced storage technologies like flow batteries is the most practical path forward.
Using this historical convention, a redox flow battery is better described as a secondary fuel cell or regenerative fuel cell, with the fundamental difference between batteries and fuel cells being whether energy is stored in a solid state electrode material (batteries) or in the electrolyte (fuel cells) .
Our solar PV systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
