Sodium-ion vs lithium-ion BESS: Cost parity not before 2031
“Europe needs massive investments in energy storage to achieve true independence. This requirement cannot be met by a single technology, let alone by depending on a single geographic area. The goal is therefore to build a storage industry and a broader grid infrastructure under the control of Western countries. A strategic and ambitious goal that will take time,” Dario Bertagna, senior managing director and co-head of Clean Energy at Capital Dynamics, told pv magazine Italia.
