Abstract

L'invention propose des moyens qui permettent d'harmoniser les influences saisonnières et météorologiques de l'énergie de régénération et les comportements prédéfinis de consommation humaine sur le réseau d'énergie, et de convertir cette harmonisation en une alimentation durable à long terme en énergie qui confère en outre de la stabilité aux réseaux existants par accumulation intermédiaire du CO2 et recours à une valorisation de ce dernier. Dans ce but, elle propose un procédé de répartition d'énergie selon lequel un réseau de courant (20) qui répartit du courant ou des charges alimente plusieurs emplacements consommateurs (21). De l'énergie (30, 31) formée par régénération par l'intermédiaire d'éoliennes ou de cellules solaires n'est pas entièrement injectée dans le réseau (20) mais utilisée au moins en proportion importante pour former de l'hydrogène (40). L'hydrogène est hydrogéné dans au moins une installation d'hydrogénation (10) en même temps que le dioxyde de carbone provenant d'autres centrales électriques (81, 82) ou d'une réserve finale (83); on forme ainsi au moins un hydrocarbure gazeux combustible (11). L'hydrocarbure combustible est valorisé de nouveau dans une centrale (81, 82) pour produire du courant électrique, le carbone circulant en cycle (100) avec amenée d'énergie (30, 31, 35) formée par régénération et fourniture d'hydrocarbure combustible.
