Tenerrdis: energy to spare to facilitate the development of hydrogen

Posted on November 16, 2022, 6:30 am

Born at the same time as regional hydrogen pioneers in the mid-2000s, Tenerrdis has supported the development of the sector since its inception. In Grenoble, in Isère, the Energy Transition Competitiveness Cluster saw cutting-edge technologies at the origin of McPhy, Sylfen, Atawey, Genvia, now industry leaders, emerge from the CEA-Liten laboratory.

From R&D to production, Tennerdis was there to help them obtain public and European funding, tap bankers, act as an intermediary with local authorities or open the doors of GRTgaz, Engie and Air Liquide.

Today, the structure supports new nuggets, Isère Inocel, in Saint-Egrève, in fuel cells, and industrialists who want to decarbonize their processes, such as the Vicat cement plant, in Montalieu-Vercieu (Isère). He called Hynamics, an EDF subsidiary that produces low-carbon hydrogen, to the Hynovi project. This also includes a CO2 capture component.

Promote the emergence of solutions

The Tennerdis “enabler” does not fund anything, but promotes the emergence of solutions, from innovation to implementation in the field. This is starting to show in mobility with Hympulsion charging stations, an innovative public-private partnership between the Auvergne-Rhône-Alpes region, Engie and Michelin.

The program includes three electrolysers for production, 20 stations for distribution and subsidies to companies for the purchase of 1,200 professional vehicles, with funding from Ademe and the European Union.

From very early on, it was necessary to bring elected representatives, hydrogen producers, transporters and terminal operators to the table.

“Far upstream, it was necessary to bring elected officials, hydrogen producers, transporters, terminal operators… A long-term job to prepare the infrastructures of tomorrow”, explains Séverine Jouanneau Si Larbi, General Delegate of Tenerrdis. Another success: the underground storage project in the Hypster salt cavities, with Storengy (an Engie subsidiary). The cluster is also a co-label of this private initiative.

The “collective dynamic” continues through a dozen projects. The renewable energies cluster has 80 members who are directly or indirectly related to hydrogen (a total of 300), from start-ups to large groups. Without forgetting SMEs, which are increasingly present in the sector.

Like SteelHy, in Sassenage, in Isère, manufacturer of pressure vessels and pipes integrated with distributors. This creation by ACS Steel, a family-owned boiler, benefited from all the support of the cluster, “research, networking, visibility, connection with hydrogen players”, details Séverine Jouanneau Si Larbi. The same goes for Ugitech, the Savoyard subsidiary of Swiss Steel, which plans to produce components for electrolyser batteries.

Complementarity of renewable energies

“There is room for everyone because the entire sector still needs to be built”, encourages the General Delegate. “At Tenerrdis, we are not opposed to technology: we are committed to the complementarity of renewable energies. “We need photovoltaic plants to produce green hydrogen. “We adapt the combinations to the territory: needs and uses are not the same in the city, in the Arve valley or in rural areas”, he adds.

The Roselend project, in Beaufortain, – associating EDF and the powidiana start-up around the Société d’Economie Alpestre de Savoie – takes into account the specificities of livestock farming and the ecological imperative of this bucolic plateau to be preserved. He is testing a mobile hydrogen-powered generator to replace diesel-powered milkers, which generate noise, smoke and odors. The demonstrator cost 100,000 euros. Eventually, the gas will be green, produced by hydroelectricity at Roselend Dam.

The mountain is an important issue in Auvergne-Rhône-Alpes: Tennerdis is proud to have joined its first European hydrogen program a few weeks ago, as an active member of the Amethyste consortium, focused on decarbonising tourism in the Alpine arc.

Train future specialists

Another upcoming project: the 1 km long hydro pipeline announced in mid-October by Compagnie Nationale du Rhône, GRTgaz and Storengy in the Chemical Valley, between the Pierre-Bénite dam, production site, and the new cell plant Symbio fuel station in Saint-Fons. The region supports the initiative and would like to see the small pipeline connected to a large pipeline, a project under study, between Germany and the port of Marseille.

But none of that will happen without the skill link. Tennerdis therefore promotes training. It has supported the creation of new specialized teaching modules Htwo at the University of Grenoble, and labeled France Relance.
