The first injection of green hydrogen at the Manosque storage site

On Thursday 13 June, green hydrogen (made in France) was injected into one of the site's salt caverns for the first time. 

170 kilos of hydrogen were injected into a cavern that is currently used for natural gas (Storengy also plans a similar trial in the Ain region).

The injected hydrogen will be swept up by the natural gas, since the hydrogen is injected simultaneously with the natural gas to "carry" the hydrogen into the cavern and homogenise the gases.

There will then be a period of observation to check for no anomalies. 

This will be followed by a destocking phase, during which the mixed gas will be analysed at the outlet to ensure that all the hydrogen has been extracted and that the mixed gas still meets the technical specifications of the GRTgaz transporter.

The preparation of this pilot project has made it possible to raise the awareness of all our teams to the new constraints associated with hydrogen and to mobilise all our skills, from the preparation of the "notification" to the operational phase, including all aspects of technical feasibility, with the Lhyfe team supplying the first 170 kilos of hydrogen.

This hydrogen injection pilot is 50% funded by ADEME, as part of the ZIBAC (Zone Industrielle Bas Carbone) programme, co-managed by Capénergies and PIICTO.

Géométhane is an Economic Interest Grouping owned equally by Storengy France and Géosud (50% of the capital). Géométhane owns its facilities and delegates operation to Storengy. The Géométhane site comprises 7 caverns that have been operating with natural gas since 1993. This storage, which corresponds to the equivalent of two-thirds of Marseille's annual gas consumption, ensures regional security of supply...
