Flow battery system for high altitude

Subcategory (under Clean Energy): Storage
Technology Readiness Level (TRL): TRL 7 - Pre-commercial demonstration
Technology Outline (Process Description)

The proposed project aims to develop a Vanadium Redox Flow Battery with an appropriate thermal management system to cater the energy demand in extreme cold climate. The system consists of 50 kWp solar PV system, 20 kW/200 kWh Vanadium Redox Flow Battery and a 2 x 15 kVA inverter. The system was commissioned to cater for the energy requirement of an Army base at an altitude of 17600 ft in the North Sikkim Forward area on 28th April 2021. The system successfully replaced a 30 kVA diesel generator and it is in operation to date and caters to the army base’s critical energy demand

Salient Features/Advantages

  • A 50 kWp solar plant is installed to cater the total energy requirements of the army base at an altitude of 17600 ft
  • A 20 kW/200 kWh vanadium redox flow battery is integrated in the system
  • A conceptual model of “Oxycafe” is capable of catering the oxygen demand on site

Key Outcomes

  • The system has survived two winters without any significant maintenance. The system has successfully supplied around ~ 40 MWh of energy annually and met 22 kW of peak power demand. The system has successfully saved ~ 27,000 L of diesel per year which in turn saves around 71 Ton of CO2 emission
