My problem is that the hob is not near an outside wall. I have looked at
hoods generally and see that most of them are vented through the wall. A few
are "island" hoods that vent vertically.

How do these things actually get vented to outside? A long flexible like a
tumble dryer pipe?

I need something that vents straight up then moves 90 degrees to follow
the ceiling joists, before exiting. A distance of two or three metres.

Use Osma soil pipe (above ground).
