The MONTCEAU project intends to study and develop the manufacture of a graphite disc with 312 “net shape” chambers using SPS (Spark Plasma Sintering) fast sintering technology with a view to implanting it in the Hydrogen 2.0 device, an innovative technology developed and patented to produce hydrogen from salt water in an industrial (large volume) and economical manner (productivity, low tool wear, no machining recovery, low energy costs). The project is intended to produce a scale 1 demonstrator (passing a TRL from 4 to 7) through the support of the expertise of the ICB laboratory (Centre Excalibure), and then to consider a start-up through an industrialisation study conducted by SINTERMAT (passing a TRL from 7 to 9). The Hydrogen 2.0 modules manufactured by the company NATUREGIE will offer an innovative supply of decentralised hydrogen production, excluding network infrastructure, truly clean and efficient, and thus make hydrogen a leading role in the energy mix.
