The increasing production of electricity from renewable energy sources has been accompanied by growing interest in technologies allowing the storage of energy. One of the means allowing its storage is the Power-to-Gas technology thanks to which the excess power may be converted into another energy carrier such as hydrogen. One possibility is to blend the resulting hydrogen with natural gas and inject it into the natural gas grid. The paper discusses both the effect that hydrogen blend has on the performance of gas pipelines, and the main thermodynamic events occurring while the mixture of hydrogen and natural gas is transported.
