Il semble que chaque jour il y ait une nouvelle annonce dans les nouvelles concernant les automobiles alimentées par des piles à combustible. Les promesses sont alléchantes, car les piles à combustible ont le potentiel de doubler très rapidement l'efficacité des voitures tout en réduisant considérablement la pollution atmosphérique..

Dans le même temps, il y a eu des reportages pendant des décennies sur les problèmes liés au pétrole. Tout, des déversements d'hydrocarbures aux alertes à l'ozone en passant par le réchauffement de la planète, est imputé à notre dépendance aux combustibles fossiles.

Ces deux forces mènent le monde vers ce que l'on appelle généralement économie de l'hydrogène. Si les prévisions sont vraies, au cours des prochaines décennies, nous commencerons tous à voir un changement étonnant de l'économie des combustibles fossiles que nous avons aujourd'hui vers un avenir à l'hydrogène beaucoup plus propre..
