Green-hydrogen projects — Fos-sur-Mer

The Fos-sur-Mer industrial basin concentrates the largest French green-hydrogen projects: hydrogen-reduced iron production, green ammonia for export, electrolysis coupled with the historical petrochemicals of the Berre lagoon, future import terminals. Each file combines Seveso ICPE constraints, neighbour acoustics, environmental impact studies and ESG certification for investors. NORMAXIS covers these aspects through ARKEMEP + ARKENOR + IRICE cross-sell.

Context

Fos — Mediterranean green-hydrogen hub

The Fos-sur-Mer port-industrial basin concentrates the ideal conditions for green-hydrogen megaprojects: available industrial land, port access for green-ammonia import/export, HV electrical network for electrolysers, existing industrial ecosystem (refineries, steel, petrochemicals) ready to consume. Several flagship projects worth several billion euros are under development or authorisation — hydrogen-reduced iron production, green ammonia for export, electrolysis coupled with petrochemicals, import terminals.

Each project requires a full ICPE file (sections 4715 hydrogen + 1416 flammable gas, often Seveso), a hazard study (EDD), an environmental impact study, a neighbour-acoustic study (existing residential exposure zones around sites), and increasingly an opposable ESG certification for investors (EIB, climate funds, banks).

Our practice

Three subsidiaries on the critical aspects

ARKEMEP

Acoustics & engineering

  • • Predictive noise-impact study for the ICPE file
  • • 3D mapping of emissions from electrolysers, compressors, blowers
  • • Acoustic treatment (enclosures, screens, technical rooms)
  • • Acceptance measurements and periodic checks

ARKENOR

Seveso ICPE file

  • • Environmental impact study (R.122-2)
  • • Biodiversity component, ERC sequence, CNPN file if protected species
  • • Natura 2000 incidence study (Fos coastal sites)
  • • Coordination with EDD and industrial-risk consultancies

IRICE

Opposable ESG and certification

  • • Effinature biodiversity certification of the operation, issued by IRICE
  • • Opposable ESG indicators for EIB, climate funds, green bonds
  • • DREAL-opposable acoustic measurements coordinated with an ISO/IEC 17025 testing laboratory partner
