Where ACC Kaiserslautern is
ACC Kaiserslautern is cancelled, and this register holds no position for it. It was to be at Kaiserslautern, Germany; the works was never placed to the precision a mark on a picture would claim, and looking for one was not thought worth doing on a project that stopped.
LOCATION NOT SOUGHT: PROJECT CANCELLED. The perimeter asks for a site the company has confirmed and a citable source can place, and the second half is research that only pays for itself on a works somebody might visit. It was on standby from May 2024 and never left it; nothing was built, and the basemap sweep of the Kaiserslautern industrial area returns the Opel works as numbered halls and nothing naming ACC. What would be bought by finding the parcel is a dot a reader would take for a building. The absence is recorded as a decision rather than left as a gap: this register looks for a position on projects that are being built, and says so where it has not looked.

- 2026-02-07CancelledACC's own statement of 7 February 2026, made to unions and confirmed publicly the same day: the projects in Germany and Italy 'had been on standby since May 2024' and the 'prerequisites' to restart them 'were unlikely to be met', with 'different scenarios' under consideration. The Italian union UILM, which made it public, says management called Termoli and Kaiserslautern 'definitively shelved'. NO EARLIER STATUS EVENT IS RECORDED: the standby of May 2024 was not read into this register at the time and is not being back-dated from a sentence written twenty-one months later.source
Technology and measures
- Gigafactory-scale cell manufacturingcommercialElectrode coating, cell assembly and formation run at gigawatt-hour scale on one site. It is the process node rather than a chemistry: the same lines make several chemistries, and what decides whether Europe has cells is whether the lines exist and yield, not which cathode runs through them.
Funding
No public capital recorded for this project.
