The engineering phase can now begin, with technical experts from all companies involved working on the detailed integration of the storage system. Once that is complete, production of the optimised battery modules will be commissioned to ensure that operations can begin on schedule. Local companies Equans Switzerland AG and Georg Fischer AG are project partners for the project.
Until this project, the only truly large-scale flow battery projects under construction in the world have been in China. Flow battery projects there are built largely on site, which is possible thanks to lower labour costs than elsewhere. Flow battery projects in Europe and the US meanwhile need to be comprised of modular units built in a factory, in order to be cost-competitive.
Flexbase first announced the project in late 2024, and got construction approval for it a year later.
Speaking to Energy-Storage.news last month, Flexbase’s Aumer said that at the time the company was still in discussion with the potential supplier, but he could share details on the project configuration.
“It’s vertically designed, so the tanks will take a separate floor, as will the stacks. This is due to the limited floor area (12,000 sqm per floor). Construction has already started with core and shell,” Aumer said, shortly after the company announced the start of construction on the project.
