H2O is not just a futurist fire prevention vehicle produced by the creative people at Peugeot. H2O produces electricity and water using fuel cell battery technology. Hidden underneath the playful and dynamic appearance of a fire engine lies a very innovative propulsion method. H2O, built on a Partner Electric base, uses the fuel cell battery as a source of on-board energy and features a major innovation for this technology: the hydrogen is produced in real time, based on the systems needs, which means it can overcome the problems associated with storing pressurized hydrogen.
