Dans le cas où une pénurie d'hydrogène se produit lorsque le volume d'alimentation en hydrogène est fourni à la pluralité de bases de demande, l'unité de calcul de la valeur d'évaluation calcule la valeur d'évaluation en plus en se basant sur le volume équivalent de dioxyde de carbone au niveau de chacune des bases de demande correspondant à la quantité utilisée d'énergie de remplacement par rapport à un volume de pénurie d'hydrogène.
