We are sharing another step in the energy transition

The incorporation of H₂ into natural gas networks is a key strategy for the decarbonization of the energy sector, although it presents significant technical challenges, particularly in terms of mixture homogenization, operational control, and infrastructure integrity.

Within this context, the H2NG project – Hydrogen and Natural Gas Mixing and Injection Station, developed by STREAM, PRF, the University of Coimbra, and ADAI, enabled the development of a complete and integrated solution for the pre-mixing and injection of hydrogen into gas networks. This solution allows for non-intrusive hydrogen injection, mitigating infrastructure fragilization phenomena (hydrogen embrittlement) and ensuring rapid homogenization of the gas mixture after injection.

The public session presenting the project results, held on April 28, featured Nuno Martinho and Pedro Silva as speakers and demonstrated to a wide audience the operation of the pilot station, the solution’s performance under dynamic conditions, as well as its robustness and ability to ensure a homogeneous, safe, and controlled H₂/NG mixture under different operating conditions.

The H2NG project therefore represents a relevant contribution to the evolution of energy infrastructures, reinforcing the technical feasibility of incorporating hydrogen as a decarbonization vector in the gas sector.

This partnership has led to the approval of two joint international patents — PRF and STREAM — and has culminated in the development of a technology that will be launched on the market in the coming days.

The H2NG project was co-financed by Centro 2030, Portugal 2030, and the European Union.
