The main objective is to investigate the optimal integration of renewable electricity generation with the natural gas grid by injecting hydrogen generated by the PEM electrolyzer developed within the ‘GreenH2Pipes’ project into the natural gas network.

To this end, the technical feasibility of direct hydrogen injection into the natural gas grid will be studied, with the aim of achieving decarbonization goals. This could also be an efficient option for hydrogen storage and transport.

To this end, the following specific objectives are proposed:

• Investigation using computational fluid dynamics (CFD) of the fluid dynamic behavior under different hydrogen injection conditions in the natural gas network.
• Investigation of the mechanical behavior of materials in the Spanish natural gas transport infrastructure after exposure to natural gas and hydrogen mixtures.
• Development of procedures for hydrogen sampling and impurity analysis associated with hydrogen injection into the natural gas network.

Investigation of the separation of natural gas and hydrogen mixtures transported through the gas infrastructure. Investigation using Bayesian machine scientists of the optimal integration of hydrogen generated from renewable sources into the gas network.
