CA 2747097

The invention relates to methods and to plants (100) for supplying storable and transportable carbon-based energy carriers (108) using carbon dioxide (101) as the carbon supplier and using electricity (E1, E2). The plant (100) comprises a plant (300, 301; 400) for generating a first energy component in the form of DC power (E1) from renewable energy sources. Furthermore, a power supply plant (501) is provided for connecting the plant (100) to a grid (500), wherein the power supply plant (501) generates a second energy component in the form of DC power (E2) from the AC voltage of the grid (500). A device (102, 105) is designed for supplying hydrogen (103), wherein a portion of the power demand by said device (102, 105) is covered by the first energy component and another portion is covered by the second energy component. A carbon dioxide feed serves to introduce carbon dioxide (101) and a reaction area (106) is provided for producing a hydrocarbon, preferably methanol (108).

Linvention concerne un procédé et une installation (100) permettant de produire des sources dénergie stockables et mobiles à base de carbone (108) en utilisant du dioxyde de carbone (101) comme source de carbone et en utilisant de lénergie électrique (E1, E2). Linstallation (100) comprend une installation (300, 301 ; 400) destinée à la production dune première part dénergie sous la forme dénergie électrique continue (E1) à partir de sources dénergie renouvelable. En outre, une installation dalimentation en énergie (501) permettant de relier linstallation (100) à un réseau de distribution (500) produit à partir de la tension alternative du réseau de distribution (500) une seconde part dénergie sous la forme dune énergie électrique continue (E2). Un dispositif (102, 105) est configuré pour fournir de lhydrogène (103), une partie de la demande en énergie de ce dispositif (102, 105) étant couverte par la première part dénergie et une autre partie par la seconde part dénergie. Une arrivée de dioxyde de carbone sert à lintroduction du dioxyde de carbone (101) et une zone de réaction (106) permet de produire un hydrocarbure, de préférence du méthanol (108).
