Point 1 must also be taken into account for the evaluation of the delivered gas mixture, since the billing is based on kWh, that is to say on the performance, but shows today's standard gas meters only the volume consumed. Since hydrogen and natural gas differ significantly in their energy content, the delivered power is calculated from the delivered volume and the average hydrogen content of the meter reading period according to point 1.

Abstract

Avec de l'hydrogène comme support d'énergie secondaire, des énergies renouvelables sont stockées en même temps que le gaz naturel et transportées par le réseau de gaz. Les énergies renouvelables sont plus rapidement disponibles sous forme d'hydrogène que sous forme d'électricité, étant donné que l'on ne doit pas construire de nouvelles lignes à haute tension. En outre, des énergies renouvelables peuvent ainsi supporter une charge de base. La présente invention décrit le transfert par exemple du courant éolien ou du courant solaire en hydrogène et son introduction dans du gaz naturel. En même temps que le gaz naturel, l'hydrogène est stocké dans le gisement de gaz naturel et/ou transporté dans le réseau de gaz de naturel au lieu de consommation. En raison des différences physiques et de combustion existant entre l'hydrogène et le gaz naturel, de tels mélanges ne doivent pas être utilisés dans le cas d'un rapport de mélange discontinu, tel qu'il apparaît dans la nature des énergies renouvelables, sans une mesure permanente de la teneur en hydrogène. Ainsi, par exemple la teneur en hydrogène doit être déterminée directement avant la combustion, et le dosage du mélange de gaz, adapté à sa puissance calorifique. Une mesure, qui devient indispensable pratiquement en tout lieu de consommation et qui doit être accompagnée aussi bien au plan technique qu'au plan juridique. Au plan technique du fait que le compteur à gaz mesure non seulement le volume, mais par exemple par la densité également la teneur en hydrogène et au plan juridique parce que la puissance calorifique variable d'un mélange hydrogène/gaz naturel fluctuant doit être prise en compte dans le droit relatif à l'étalonnage. Comme le traitement selon l'invention d'un mélange gazeux fluctuant nécessite donc une préparation minutieuse pour le marché, il peut être avantageux de collecter l'hydrogène quelque temps dans le gisement de gaz naturel, alors que du gaz naturel non encore mélangé est transporté et livré. A cet effet, l'hydrogène est introduit dans le gisement de gaz naturel et, dès que la présence d'hydrogène peut être décelée dans le gaz naturel transporté, celui-ci est séparé du gaz naturel et réacheminé dans le gisement de gaz naturel. Cette variante de procédé convient particulièrement dans le cas où le gaz naturel peut être toujours liquéfié à froid et séparé de l'hydrogène gazeux sous forme de gaz liquide. L'hydrogène est réacheminé dans le gisement et le gaz naturel est transporté et livré sous forme de gaz liquide. L'hydrogène provenant d'énergies renouvelables peut être utilisé ainsi également par refoulement du gaz naturel dans son gisement de façon avantageuse pour l'extraction de gaz naturel. Du fait qu'on sépare alors pendant une période prolongée l'hydrogène du gaz naturel transporté et qu'on le réachemine, on peut augmenter, en fonction de la structure géologique, également la quantité de gaz naturel exploitable (gaz récupérable) d'un gisement. Le gaz naturel qui, pour un volume de gaz identique, présente pratiquement le triple de la puissance calorifique de l'hydrogène, est soumis avec l'hydrogène léger à une "extraction par lavage" du gisement. Indépendamment de la variante de procédé choisie, l'ensemble de la logistique du gaz naturel sera mis à la disposition des énergies renouvelables sous la forme d'hydrogène à la fin du transport de gaz naturel. Les énergies renouvelables remplacent peu à peu le support énergétique qu'est le gaz naturel dans le gisement, le réseau de gaz ou de façon générale lors du transport ou chez le consommateur, afin de suivre ensuite le gaz naturel. Le gaz naturel devient une matière première qui se régénère - les parcs d'éoliennes et les fermes solaires deviennent des champs de gaz.
