Batteries fuel HPA demand: CRU, page-8

Cant verify the point why CRU did not talk about hydros own producing capacity of HPA?!
Within Altechs presentation hydro isnt already listet. Thereby hydro is in my mind the biggest producer of 4N to 6N HPA in the world. Found some following numbers on its homepage

Located in Vennesla at the lower part of the Otra River, the Vigeland Metal Refinery, organized within Hydro's Primary Metal division, has an annual production capacity of 8,500 tonnes of high-purity (99.99-99.999%) aluminium. Located on site, the AS Vigelands Brug "run-on-the-river" power station produces about 180 GWh in a normal year.

Further (but only at german)

Heute verkauft Hydro Aluminium High Purity GmbH rund 5.000 Tonnen im Jahr. Besonders viel davon geht an die High-Tech-Industrie in Asien. Darum unterhält Hydro auch ein Vertriebsbüro in Tokio.
(short translation: Hydro Aluminium High Purity GmbH (a subsidiary of Hydro Norilsk) sells about 5.000 tonnes of high purity alumina per year. A large part goes to the high-tech industry in Asia. That's why Hydro also maintains a sales office in Tokio!)
