Vallée Sud Hydrogène

SPIE played an instrumental role in designing and installing two renewable hydrogen production and distribution stations in Hauts-de-Seine (France).

To help meet France’s growing demand for clean public transport, SPIE equipped two production and distribution stations in the Hauts-de-Seine cities of Châtenay-Malabry and Châtillon. For customer Vallée Sud Hydrogène, SPIE provided the stations’ turnkey electrical, automation and instrumentation systems. The Châtenay-Malabry site consists of an electrolysis hydrogen production station that produces hydrogen, which can be compressed and stored at several pressure levels (from 500 to 1,000 bar). The Châtillon site, equipped with a storage and distribution area, obtains its hydrogen supply from the Châtenay-Malabry site. The stations help Vallée Sud Hydrogène to power 30 buses managed by Île-de-France Mobilités and 27 household waste collection vehicles. With a production and distribution capacity of up to two tonnes of hydrogen per day, the stations make a significant contribution to decarbonising transport in the region.
