The total production number is around 25k globally from the start to now; currently the factory could produce ~20k units a year, with the option of adding a shift to enter the 30k unit per year production range.55 k would be nearly twice the potential factory output in Hambach.
Don’t know if they reached the 30 k all over from beginning by now.
A yearly production of 25k would be a dream for Ineos at the moment!
55,000 units a year is both outside the scope of realistic sales and realistic production
