Title
(EN) METHOD FOR HYDROGEN PRODUCTION VIA METAL-WATER REACTION
(FR) PROCÉDÉ DE PRODUCTION D'HYDROGÈNE PAR RÉACTION MÉTAL-EAU
Abstract
(EN)
Hydrogen gas is produced by exposing a metal to an aqueous solution, wherein the aqueous solution is under supercritical conditions or is at a temperature of at least 200°C and at a pressure of at least the saturated vapor pressure of water at said temperature. Metals include A1, B, Mg, Si, Ti, Mn, and Zn. Metal oxides and/or metal hydroxides may also be recovered. The process may potentially be used to produce hydrogen on demand with applications in producing clean energy.
(FR)
L'hydrogène gazeux est produit par exposition d'un métal à une solution aqueuse, la solution aqueuse étant dans des conditions supercritiques ou étant à une température d'au moins 200 °C et à une pression d'au moins la pression de vapeur saturée de l'eau à ladite température. Les métaux comprennent Al, B, Mg, Si, Ti, Mn et Zn. Des oxydes métalliques et/ou des hydroxydes métalliques peuvent également être récupérés. Le procédé peut potentiellement être utilisé pour produire de l'hydrogène à la demande avec des applications dans la production d'énergie propre.
