Note:
This paper proposes a critical analysis of the possible roles that hydrogen may have in the future as an energy carrier. The discussion is based on the status of current and mature technologies, on forecasts about upcoming opportunities for hydrogen production, management and use, and one general environmental, social and economical considerations. The attention is focused on the transportation sector, where recent scientific studies have proposed well-to wheel primary energy consumption comparisons between several scenarios, in the long term, for vehicle propulsion, based on the analysis of the global life cycle and the overall induced environmental impact. For zero-local-emissions urban transportation, these studies indicate that both battery operated fully electric vehicles and hybrid vehicles have the potential to offer greater differential advantages from a global point of view, than hydrogen operated fuel-cell vehicles.
