Methanation Of Co 2 Storage Of Renewable Energy In A Gas Distribution System

This article presents one auspicious consequence of the frequent research project entitled ?Storage of electric energy from renewable sources in the natural gas grid-water electrolysis and synthesis of gas components?. The project was funded by BMBF and imaginary at countrified viable concepts for the storage of surplus electrical energy from wind and solar power plants. The assumption free in this article suggests the conversion of CO2-containing gases now methane in a rushed reactor using hydrogen bent via electrolysis. The bent gas can be upgraded to artificial natural gas (SNG) and fed now the powerful German natural gas grid. This assumption benefits from the gigantic storage capacity of the German gas grid and does not normal any extensions of the principal gas or power grid. The reaction heat free of charge by the exothermic methanation reaction leads to a stage strengthen of the gas in the final bed facilitator of the reactor. The conversion of carbon dioxide is partial in unity to the chemical compare which depends fervently on stage and persuade. For greatest carbon dioxide conversion, it is matter-of-fact to break the methanation now particular stages extra cooling sections in between. This article focuses on the methanation process and its pack off onto an commercial scale evaluating the different plant capacities and feedstock mixtures used. The methanation takes repair in a staged final bed reactor. This staged reactor assumption is an inside development based on know-how from the sulfuric in focus production technology.
