Chinese vanadium redox battery manufacturer VRB Energy has begun commissioning a 3MW/12MWH vanadium redox battery, phase one of its Hubei Zaoyang 10MW/40MWh project, which will be the “largest vanadium flow battery installed in China”.

The system is being installed to integrate a large solar photovoltaic system into the grid at Zaoyang.

VRB’s chief technical officer Dr Mianyan Huang said: “We are delighted to have successfully integrated the first module of a 1MW/4MWh VRB-ESS into the grid, allowing our customer, Hubei Pingfan, to immediately benefit from cost-savings on peak-hour electricity tariffs through energy arbitrage at its industrial park.”
