Little extra fun fact since Norsk Hydro was mentioned in the article and now you've mentioned it again-

Norsk Hydro was founded as a hydro power plant + nitrogen fertilizer production company (the nitrogen production needing lots of electricity, and the hydro plant to provide said energy...) but around WWII, pivoted to light metals, and built aluminum and magnesium factories with German company IG Farben, in order to support them in the war, as they were partially under Nazi occupation by then. That all went south but then after the war they kept on with the aluminum business.

The company went on to become experts in aluminum extrusions, and were then contracted not just for the base metal but also to manufacture the first bonded aluminum bare chassis for the S1 Lotus Elise in 1995, which went on to be the basis for the Tesla Roadster.
