Synthetic Natural Gas (SNG for short) refers to a gas mixture similar to natural gas with methane as its main component, which has been produced by synthesis. SNG synthesis is a possible way to store large amounts of electrical energy as chemical energy, even over long periods of time. The starting materials for SNG synthesis are hydrogen and carbon monoxide or carbon dioxide (synthesis gas). The plant consists of the synthesis gas mixing section, a gas preheater, a cascade of up to three reactor stacks and connected online analysis of the product gas. Between the reactors, the reaction heat can be dissipated via heat exchangers. Due to the variable character of the plant, different synthesis gas compositions, reactor configurations and waste heat utilisation concepts can be tested and data can be determined, e.g. for modelling. It is possible to couple the plant with an electrolyser and thus to investigate power-to-gas concepts in their entirety.
