A flow battery consists of tanks, a pump system and battery cells, also known as a battery stack. The tanks contain a liquid electrolyte solution that serves as a storage medium. The electrolyte is pumped through the battery cells to charge and discharge the battery, binding electrons.
[pdf] Under the MFF Power Transmission Enhancement Investment Program II Tranche 3, the ADB has commenced a project in Pakistan which centres on the deployment of a modular lithium-ion battery energy storage system (BESS), which can be conveniently housed in standard shipping containers.
[pdf] Grid scale BESS can be used for frequency regulation, peak shaving (i.e. reducing demand during peak hours to lower grid stress or avoid high tariffs) and grid stability. The 750 kW BESS project at the PECC2 Innovation Hub in Ho Chi Minh City is an example of this.
