H2 technology turning pretty nifty
un sujet a posté Flo dans Urbanisme, architecture et technologies urbaines
Alstom is delivering Hydrogen-fuelled intercity Coradia trains to Lower Saxony. The locomotive and motor engine were manufactured in France whilst the Hydrogen cell was made in Germany. In terms of fuel supply, Hydrogen is generated by electrolysis and the energy used to power this reaction is tapped from wind power. Functionally-speaking, energy is generated by converting H2 gas to electricity using reverse electrolysis - an old technology discovered back in the 19th century. A single H2 fill-up drives the engine with an autonomy of 1,000 km plus the possibility of peaking up to 140 km/h. This is a direct alternative to diesel trains, the motor engine itself is electric, hence quiet, and overhead lines are history. H2 is stored in a highly pressurized state and withheld inside reservoirs bearing high tensile strength, still I ponder on the event of an accident given its extremely exothermic nature. Anyway, I often hear people arguing over job losses through delocalized assembly lines or trivial companies moving to Calgary or Toronto and always thought Montreal (besides France and Germany BTW, coz I deeply love these 2 cultures ) had all what it takes to unleash innovative industries that would disrupt traditional transport and energy markets (kind like the way Apple's smartphones relegated Nokia's mobile technology to oblivion). Quebec has top universities that lead research in the Physical Sciences, lots of natural resources and genuine reasons to curb climate change. One could imagine developing shuttles that use hydrogen cells to transit people from one bank of the Saint Laurent to another. La Rochelle already has one such gizmo and Marseille has been using a solar-powered equivalent to move people around the Vieux-Port.
