Title
(EN) ENERGY STORAGE USING AN REP WITH AN ENGINE
(FR) STOCKAGE D'ÉNERGIE UTILISANT UN REP (REFORMEUR-ÉLECTROLYSEUR-PURIFICATEUR) POURVU D'UN MOTEUR
Abstract
(EN)
An energy storage system includes a power plant configured to generate an exhaust gas comprising carbon dioxide. The energy storage system further includes a first fuel cell configured to operate in reverse as an electrolyzer. The first fuel cell is configured to receive at least a portion of the exhaust gas from the power plant. An anode is configured to receive carbon dioxide via the exhaust gas and methane from a separate feed, and the anode is configured to output a hydrogen-containing gas mixture. The energy storage system further includes a reformer configured to methanate the hydrogen-containing gas mixture to convert substantially all of the carbon monoxide in the hydrogen-containing gas mixture to methane. The energy storage system further includes a second fuel cell operating in reverse as a hydrogen pump, the second fuel cell configured to separate hydrogen from a gas mixture output by the reformer.

Un système de stockage d'énergie comprend un moteur conçu pour générer un gaz d'échappement comprenant du dioxyde de carbone. Le système de stockage d'énergie comprend en outre une première pile à combustible conçue pour fonctionner à l'inverse comme un électrolyseur. La première pile à combustible est conçue pour recevoir au moins une partie des gaz d'échappement du moteur. Une anode est conçue pour recevoir le dioxyde de carbone par le gaz d'échappement et le méthane d'une alimentation séparée, et l'anode est conçue de façon à produire un mélange gazeux contenant de l'hydrogène. Le système de stockage d'énergie comprend également un reformeur pour soumettre à la méthanation le mélange gazeux contenant de l'hydrogène afin de convertir sensiblement la totalité du monoxyde de carbone du mélange gazeux contenant de l'hydrogène en méthane. Le système de stockage d'énergie comprend en outre une seconde pile à combustible fonctionnant à l'inverse comme une pompe à hydrogène, la seconde pile à combustible étant conçue pour séparer l'hydrogène d'un mélange gazeux émis par le reformeur.
