nnovation labs seems to become part of airports business models. Interestingly, the type of innovations developed are completely different from one platform to another. This suggests that a classification could be helpful, especially when public investment is also concerned. We propose in this paper, in the light of the case study of the hydrogen production at Toulouse Blagnac airport, a methodology to classify the innovations at airports. This classification is supported by a literature review on sustainable and disruptive innovations theories, which helps us identifying factors that drive and characterize these innovations and checking the relevancy of these factors for our case study
