The question is in a title. I am solving the NSE on 2D grid. Thus there is only one component of the vorticity. Is it stored at the cell center like pressure?

No, you need to think about its definition du/dy-dv/dx, discretized with second order central formula on the step sizes dx and dy. |

Ok thanks. Now that I think about it, the vorticity will be at the cell center due to taking derivatives.
