Vanadium Redox Flow Battery based Charging Station for Electronic Devices inaugurated at IIT Delhi

IIT Delhi’s Sustainable Environergy Research Lab (SERL) at the Department of Chemical Engineering is actively working on Vanadium Redox Flow Battery (VRFB) technology. Recently, a VRFB based charging station, especially designed under the Smart Campus Initiative of the Institute, was inaugurated on the campus.

The stored energy in the charging station can be used to charge portable electronic devices such as mobile phones, laptops, tablets, and power banks using various charging ports provided in the station. The team has designed it for charging operation of around 9 hours in a day. The benefit of the charging facility can be availed by the IIT Delhi community as well as the visitors.

Dr. Anil Verma, Professor at Chemical Engineering Department, IIT Delhi said that the research group led by him developed the 2nd generation prototype in the SERL so that the technological and scientific contribution in the form of an environmentally friendly viable product could be available to society. He has informed us that the group is working on a kW level battery stack. The project is funded by DST, MHRD, and IIT Delhi.

“The research team will collect the operational data of the developed prototype in the ambient and live conditions so that appropriate changes in the design and operation can be incorporated in the next scaled-up version,” Prof Verma added.

The facility was inaugurated by Prof. V. Ramgopal Rao, Director in the presence of Deputy Directors (Operations, and Strategy & Planning) and other dignitaries.

What is a VRFB

VRFB utilizes liquid electrolytes to store electrical energy. During charging, the electrical energy is stored in the liquid electrolyte and during discharging the stored energy is used for various applications.

Key Features of a VRFB

The VRFB can efficiently store and utilize renewable energy for a wide range of applications such as rural electrification, e-vehicle charging station, domestic and commercial power back-up etc. leading to zero carbon footprint.

It is non-polluting (no emissions), easily scalable, safe and environmentally friendly, and highly durable. One of the major differences between the flow and conventional battery is the independent scaling of power and energy capacity.

The VRFB can store energy from kWh to MWh range and suitable for long discharge time with low cost in contrast to the conventional battery. The technology is highly suitable wherever diesel generators are used.
