February 6, 2020: UK energy storage technology firm Connected Energy has had its largest second-life E-STOR battery energy storage system to date commissioned at Umicore’s industrial site in Belgium, the firm announced on January 28.
It has an energy storage capacity of 720kWh and can deliver 1.2MW in power, the firm said.
The system uses Renault batteries that previously powered Kangoo vehicles in France, said the company, which signed a deal in 2016 with Groupe Renault to work with second-life battery storage technology.
“The collaboration with Connected Energy, which has been ongoing for three years, is the beginning of a great story,” said Renault’s batteries operation and business director Amaury Gailiez. “Our second-life batteries are very appropriate for these energy storage applications.”
The system for Umicore has been developed to provide firm frequency response, as the world moves away from a centralized energy model, said Connected Energy CEO Matthew Lumsden.
“Instead we’re seeing a distributed renewables energy set-up, with many renewable energy sites across countries as opposed to fewer, larger facilities. These renewable energy sources have their own volatilities that impact on grid frequency — a problem energy storage can help solve,” he said.
