Méthodes d’ergonomie prospective appliquées à l’identification de besoins pour des systèmes d’énergie à base d’hydrogène : étude exploratoire

Abstract

The energy transition has become a major challenge, even an emergency and a real societal will. Today and tomorrow, we must imagine the needs and future uses of alternative energies such as hydrogen could bring us. To achieve this, we must define and design innovative services that will meet the future expectations of tomorrow's users. But how can we imagine and evaluate products and services when they do not yet exist? How to analyze activities and uses that do not yet exist either? How to work with ergonomics on what will be? To address these issues, it is necessary to introduce prospective in ergonomic approaches, called prospective ergonomics. Therefore, in the context of research on the future uses of hydrogen as energy, we have organized three focus groups of hydrogen experts (in the sectors of production, transport and distribution of energy) and we did an automatic and thematic analysis of their verbal exchanges. This article describes this research by highlighting the major classes of the verbal exchanges, themes gathering human needs and finally descriptions of future users on the basis of the methodology of the personas. The main role of these representations is to facilitate ideation in order to allow hydrogen professionals to design new products and innovative services.
