Pour soutenir les objectifs mondiaux de d\u00e9carbonisation, l’int\u00e9r\u00eat pour les navires aliment\u00e9s \u00e0 l’hydrog\u00e8ne s’accro\u00eet. Efectis contribue activement \u00e0 cette transition en se concentrant sur les aspects de s\u00e9curit\u00e9 incendie et explosion du stockage et de la dispersion de l’hydrog\u00e8ne en milieu marin.<\/strong><\/p>\n\n\n\n

L’hydrog\u00e8ne comprim\u00e9 (CH\u2082) et l’hydrog\u00e8ne liqu\u00e9fi\u00e9 (LH\u2082) sont les principales options de stockage pour ce type d’utilisation. Alors que le LH\u2082 offre une densit\u00e9 \u00e9nerg\u00e9tique plus \u00e9lev\u00e9e, le CH\u2082 offre une plus grande efficacit\u00e9 \u00e9nerg\u00e9tique et un ravitaillement plus simple. Dans les deux cas, la s\u00e9curit\u00e9 reste un d\u00e9fi majeur, notamment en ce qui concerne le comportement des fuites, la formation de nuages de gaz inflammables et les performances de ventilation dans les espaces confin\u00e9s.<\/p>\n\n\n\n

L’un de nos r\u00e9cents projets a port\u00e9 sur l’int\u00e9gration de syst\u00e8mes \u00e0 hydrog\u00e8ne dans un navire de service typique, servant de cas de r\u00e9f\u00e9rence pour \u00e9valuer les solutions de conception et les strat\u00e9gies d’att\u00e9nuation des risques. Efectis applique une mod\u00e9lisation avanc\u00e9e de la dynamique des fluides num\u00e9rique (CFD) pour simuler la dispersion de l’hydrog\u00e8ne dans divers sc\u00e9narios de fuite, en tenant compte de facteurs tels que la disposition de la ventilation, les taux de rejet et les seuils d’inflammabilit\u00e9.<\/p>\n\n\n\n

Si vous souhaitez en savoir plus sur nos activit\u00e9s de recherche ou de mod\u00e9lisation en mati\u00e8re de s\u00e9curit\u00e9 de l’hydrog\u00e8ne, n’h\u00e9sitez pas \u00e0 nous contacter.<\/p>\n\n\n\n
