Mcphy Energy: Mcphy and the Valorem Group Sign a Contract to Supply Equipment as Part of the "Rouen Vallée Hydrogène" Project to Support Energy Transition in Normandy

• McPhy has signed a contract with the VALOREM Group for the supply of a 1 MW McLyzer electrolyzer and a McFilling station 350

• A second contract includes 8-year maintenance of all the equipment

• These contracts are part of the “Rouen Vallée Hydrogène” (RVH2) project, which aims to establish a renewable hydrogen ecosystem within the Greater Rouen Normandy area (“Métropole Rouen Normandie”), by the 1st quarter of 2026

• RVH2 is winner of the Calls for Project launched by the ADEME and the European CEF AFIF program, and is supported by the Normandy Region

• This signing is a key step in the development of the RVH2 project, setting up the production and distribution of renewable hydrogen for mobility and industry on a regional scale

Grenoble, May 13, 2024 – 6:00 pm CEST – McPhy Energy, specialized in low-carbon hydrogen production and distribution equipment (electrolyzers and refueling stations), today announces that it has been selected by the VALOREM Group, a pioneer in green energy in France, and its construction subsidiary VALREA, to support them in the implementation of the “Rouen Vallée Hydrogène” (RVH2) project. McPhy will provide a1 MW electrolyzer and a 350 bar McFilling station to power public transport vehicles in the Greater Rouen area and provide renewable hydrogen to local industrial sites.

Supported by the VALOREM Group and Métropole Rouen Normandie, RVH2 was initiated in 2021 as part of ADEME's "Territorial Hydrogen Ecosystems" (“Ecosystèmes territoriaux hydrogène”, in French) call for projects. It aims at contributing significantly to the implementation of the Rouen metropolitan area's energy roadmap by developing complementary infrastructures.

The project involves setting up a local ecosystem to produce and distribute renewable hydrogen. It includes the installation of an electrolyzer, supplied by McPhy, entirely powered by green electricity produced by VALOREM. The hydrogen produced by the McLyzer electrolyzer will be used to supply a refueling station for a fleet of 14 buses purchased by the local authority, using 350-bar high-flow refueling points. Any excess hydrogen produced on site will be loaded into tube trailers and transferred to meet local industrial sites' needs for renewable hydrogen ("Hydrogen Hub" function). All of the equipment is expected to be commissioned in January 2026.

With the creation of this ecosystem, RVH2 is the 5th "Hydrogen Hub" initiative for which McPhy gets involved, following HyPORT (Toulouse), ZEV (Clermont-Ferrand), R-HYNOCA (Strasbourg) and H2NFC (Belfort).

In the framework of this project, a second contract for maintenance and technical support has been signed for an 8-year term. The service, provided entirely by McPhy, will be executed in collaboration with TSG Group, McPhy's preferred partner for the maintenance of its equipment.

Furthermore, the supply and maintenance of the 350 bar station will be subcontracted to Atawey, as part of McPhy’s proposed sale of its stations business.

Philippe Etur, Deputy Managing Director of VALOREM Group, stated: "We are delighted with this collaboration with McPhy. This is a significant step in the development of the renewable hydrogen ecosystem, in which the VALOREM Group has control over the entire value chain, including building the infrastructure carried out by our construction subsidiary VALREA. By scaling its projects in line with the territories' objectives, VALOREM is promoting joint development with local authorities and industrial firms in order to support ecological transition locally.

Jean-Baptiste Lucas, Chief Executive Officer of McPhy, states: “We are proud that Groupe VALOREM has selected us to execute the RVH2 project. We are convinced that hydrogen is key to the energy transition in urban areas. RVH2 is the 5th “hub” for which McPhy is bringing its know-how.”
