  We report on the calculation of the two-loop penguin amplitudes in
non-leptonic B decays in the framework of QCD factorization. We discuss the
computation of this genuine two-loop, two-scale problem and provide details on
the matching from QCD onto SCET, the evaluation of the master integrals, and
the convolution of the hard scattering kernels with the light-cone distribution
amplitude of the light meson. Preliminary results on the size of the two-loop
correction are given.
