Hyguane, un acronyme qui signifie \u2018 Guyanais \u00e9cologiquement neutre \u00bb
\u2019 Hydrogen \u00bb est un projet ambitieux men\u00e9 par l\u2019Agence spatiale europ\u00e9enne (ESA) avec
L'agence spatiale fran\u00e7aise CNES et ses partenaires industriels et universitaires pour d\u00e9velopper un
\u00e9cosyst\u00e8me d'hydrog\u00e8ne bas-carbone au Centre Spatial Guyanais en Guyane fran\u00e7aise.
Julia Talamoni, ing\u00e9nieure en transition \u00e9nerg\u00e9tique pour le projet Hyguane, explique,
\u201cLe projet Hyguane vise \u00e0 produire de l'hydrog\u00e8ne bas-carbone pour alimenter Ariane 6.
Actuellement, l'hydrog\u00e8ne utilis\u00e9 est produit en Guyane fran\u00e7aise \u00e0 partir de m\u00e9thanol
le reformage \u00e0 la vapeur. Ce proc\u00e9d\u00e9 produit de grandes quantit\u00e9s de carbone et n\u00e9cessite
chaleur externe importante et du m\u00e9thanol, rendant le spatioport d\u00e9pendant de
alimentation ext\u00e9rieure. Le projet Hyguane s'inscrit donc dans une d\u00e9marche plus large visant \u00e0
r\u00e9duire l'empreinte carbone des activit\u00e9s spatiales et \u0153uvre \u00e0 renforcer
la souverainet\u00e9 et l'autonomie de l'acc\u00e8s europ\u00e9en \u00e0 l'espace. Pour une bas-carbone
\u00e9lectrolyse de l'eau de l'hydrog\u00e8ne, l'\u00e9lectricit\u00e9 utilis\u00e9e doit provenir d'une
source d'\u00e9nergie renouvelable. \u201c L'installation de la ferme solaire PV3 fournit une faible
alimentation en carbone vers l'\u00e9lectrolyseur d'eau, conduisant \u00e0 la production d'un
\u201c mol\u00e9cule bas-carbone \u201d, explique Julia.
Le projet pilote d'Hyguane aura pour objectif de produire entre 10 et 151 TP3T d'hydrog\u00e8ne pour Ariane 6
besoins par an. Au-del\u00e0 de cela, l'\u00e9cosyst\u00e8me Hyguane fournira de l'hydrog\u00e8ne pour
carburant pour v\u00e9hicules lourds en Guyane pour la mobilit\u00e9 r\u00e9gionale et pour produire
\u00e9nergie par piles \u00e0 combustible \u00e0 hydrog\u00e8ne, y compris la sauvegarde \u00e9lectrique des syst\u00e8mes critiques
les syst\u00e8mes d'infrastructure au Centre spatial europ\u00e9en en cas de panne de courant.
HYGUANE Hydrog\u00e8ne bas carbone d'ici 2026.<\/p>\n

L'\u00e9cosyst\u00e8me Hyguane sera compl\u00e9t\u00e9 par la construction d'une hydrog\u00e9nation
station de ravitaillement et, dans l'attente d'un financement des \u00c9tats membres de l'ESA, d'un garage pour
entretenir les v\u00e9hicules \u00e0 hydrog\u00e8ne.
Les travaux ont d\u00e9j\u00e0 commenc\u00e9 sur une usine d'\u00e9lectrolyse d'eau et sur une usine d'hydrog\u00e8ne
centre de conditionnement utilis\u00e9 pour comprimer et pr\u00e9parer l'hydrog\u00e8ne produit pour
transport, avec le d\u00e9but des travaux sur les autres \u00e9l\u00e9ments du projet pr\u00e9vu pour 2026.
Selon Teddy Peponnet, responsable du projet Hyguane \u00e0 l\u2019ESA, \u201c Le plein
L'\u00e9cosyst\u00e8me HYGUANE sera mis en service d'ici le second semestre 2027, signature
\u201dLa premi\u00e8re Ariane 6 \u00e0 hydrog\u00e8ne bas-carbone pr\u00eate pour le lancement.\"<\/p>\n

This process produces high amounts of carbon and requiressignificant external heat and methanol, making the spaceport dependent onexternal supply. The Hyguane project is therefore part of a broader initiative toreduce the carbon footprint of space activities and works towards strengtheningthe sovereignty and autonomy of European access to space.\u201d For a low-carbonwater electrolysis of hydrogen, the electricity used needs to come from arenewable energy source. \u201cThe installation of the PV3 solar farm provides a low-carbon power supply to the water electrolyser, leading to the production of a\u201clow-carbon molecule\u201d, explains Julia.The pilot scheme of Hyguane will aim to produce 10 to 15% of Ariane 6 hydrogenneeds per year.
