The partners of the GRHYD project have inaugurated France’s first Power-to-Gas demonstrator.

Located in Cappelle-la-Grande (Nord Department), the GRHYD (Gestion des Réseaux par l’injection d’Hydrogène pour Décarboner les énergies [grid management through the injection of hydrogen (H2) for energy decarbonisation]) project launched in 2014. It tests the injection of H2 into the region’s natural gas distribution grid to meet residents’ needs in terms of heating, domestic hot water and cooking.

This innovative initiative is earmarked for reducing greenhouse gas emissions by 20% by 2020, as wished by the French government. GRHYD is a tangible illustration of the Hydrogen Plan, which the government launched on 1st June, 2018.

The GRHYD project has a key role in the strategy of the Hauts-de-France region’s third industrial evolution, under the coordination of ENGIE, represented by its ENGIE Lab CRIGEN research centre linked up with 10 other partners: AREVA H2Gen, CEA, CETIAT, Dunkirk Urban Community, ENGIE Ineo, GNVERT, GRDF, INERIS, McPhy, and STDE.

The demonstrator also receives the support of the French state as part of the Future Investments Programme run by ADEME (French Environment and Energy Management Agency), and accredited by the Tenerrdis competitive industry cluster.

Its inauguration marks the start of the demonstration with the injection of the first H2 molecules into the local natural gas grid, at a level of 6% to begin with (and up to a maximum of 20%), for supplying the 100 households and the health centre’s boiler in the “Petit Village” district of Cappelle-la-Grande. The aim of this two-year phase is to validate the technical and economic relevance of converting electricity into a new gas via a combination of H2 and natural gas.

McPhy’s Chairman and CEO Pascal Mauberger commented, “Lighting or heating our homes, our companies, moving people and merchandises, producing the goods and services necessary to our daily comfort - energy shapes the world we live in.”

“For more than ten years, McPhy helps transform energy, by accelerating the widespread adoption of clean energy thanks to the H2 vector. Whether it is for decarbonizing the energy mix, for industrial use or for the transportation sector: H2 has shown itself to be an efficient, reliable and competitive solution to succeed in energy transition.”

“We are proud to provide our expertise in the H2 solid-state storage to the GRHYD project, hence contributing – alongside our partners – to the success of this unique initiative, which is opening up the future of Power-to-Gas in France.”
