Double diffractive Higgs boson production is assessed in the picture of composite Pomeron collisions. It is shown how the introduction of Pomeron parton densities allows to describe some critical aspects of the existing data, and how these and future measurements of double diffractive dijet production will allow to constrain the non-perturbative parameters involved in the process.
