The project aims to create a modular, scalable, and utility-scale vanadium flow battery energy storage system (BESS) that is both cost-effective and home-grown, supporting AVL's “pit to battery” strategy. With 2,500+ hours of annual sunshine yet only 15% electrification rates in rural areas, Niger's energy paradox demands. . It is China Petroleum's first zinc-bromine flow battery energy storage system project, which can meet the actual needs of off-grid remote well sites for 4 to 24 hours of energy storage and low-temperature discharge at minus 25 degrees Celsius in winter.

Vanadium's exceptional properties make it ideal for vanadium flow batteries (VFB), a rising contender in the field of long-duration energy storage. Battery storage allows you to store electricity generated by solar panels during the day for use later, like at night when the sun. .
