I think i read that they could not deliver the quality and quantity expected for automobile production. Bad product, overextension and I won’t be surprised if some graft will show up once they start digging. Norway has another such venture where the executive suite pays themselves handily and delivered nothing.

Northvolt also counted on cheap materials from Russia, e.g. infamously environment unfriendly nickel from Norilsk, which clearly didn't pan out after the 2022 invasion of Ukraine.
