Interesting question but we can only speculate.
An existing project from ~1998 setup with J Burba and others, many fingers in the pie, to one designed from scratch with full autonomy and the benefit of experience and modern improvements, ~20 years later.
Not really comparable is it.
We will find out soon enough.

The company has not in any guidance hinted at selling industrial grade product.

I asked again this morning and the guidance is.... BG or as required to consumer.

The final runs of the pilot plant must have been good enough for them to believe that this will happen for the commercial plant - 2ktpa battery grade.
