Hydrog\u00e8ne: Pourquoi et comment?<\/strong><\/p>\n\n\n\n

R\u00e9sum\u00e9:<\/strong>

Les politiques \u00e9nerg\u00e9tiques li\u00e9es \u00e0 l\u2019hydrog\u00e8ne varient selon les \u00c9tats.<\/p>\n\n\n\n

Tout d\u2019abord, pourquoi l\u2019hydrog\u00e8ne ? Cette petite mol\u00e9cule est avant tout un vecteur d\u2019\u00e9nergie, puisqu\u2019elle transporte des \u00e9lectrons. Mais elle constitue aussi la base de trois productions majeures :<\/p>\n\n\n\n

\u00b7 L\u2019ammoniac (NH\u2083)<\/strong>, indispensable \u00e0 la fabrication d\u2019engrais ;<\/p>\n\n\n\n

\u00b7 Le m\u00e9thanol<\/strong> et les carburants d\u2019aviation durables (SAF : Sustainable Aviation Fuel)<\/strong>, essentiels pour la d\u00e9carbonation de l\u2019industrie chimique et des transports ;<\/p>\n\n\n\n

\u00b7 La sid\u00e9rurgie verte<\/strong>, qui vise \u00e0 r\u00e9duire drastiquement les \u00e9missions li\u00e9es \u00e0 la production d\u2019acier.<\/p>\n\n\n\n

Les acteurs du march\u00e9 de l\u2019hydrog\u00e8ne incluent les producteurs, les transporteurs (y compris le stockage) et, enfin, les consommateurs. En Suisse, quelques acteurs sont pr\u00e9sents, principalement sur le segment de la mobilit\u00e9, sur les routes, dans les airs et sur l\u2019eau.<\/p>\n\n\n\n

La production d\u2019hydrog\u00e8ne bas carbone repose sur deux technologies principales : l\u2019\u00e9lectrolyse de l\u2019eau<\/strong> et la plasmolyse du m\u00e9thane<\/strong>, qui seront pr\u00e9sent\u00e9es.<\/p>\n\n\n\n

Enfin, nous discuterons de la place de l\u2019hydrog\u00e8ne dans le paysage \u00e9nerg\u00e9tique europ\u00e9en pour les ann\u00e9es \u00e0 venir..<\/p>\n\n\n\n

Parcours: <\/strong><\/p>\n\n\n\n

Hubert Girault est Professeur Em\u00e9rite de l\u2019EPFL o\u00f9 il a enseign\u00e9 l\u2019\u00e9lectrochimie pendant de nombreuses ann\u00e9es. Il dirige maintenant H2ValSmart, soci\u00e9t\u00e9 de conseil active dans la production et l\u2019utilisation de l\u2019hydrog\u00e8ne. <\/p>\n\n\n\n
