Hydrogen is known to the general public for its energy power. It is considered, as electricity, as one of the energy carriers of the future. Water electrolysis, still too little used to produce hydrogen, is an advantageous process because it has the particularity of using electrical energy that can be produced by New and Renewable Energies. However, this process is still too expensive compared to natural gas mainly because of the cost of equipment. The aim of the ECO-H2 project is to develop an electrolyser for domestic uses by responding to specific technical and economic constraints such as low environmental impact, personal safety assurance, compactness, energy efficiency and the reduction of CAPEX. This project is supported by 6TMIC, in collaboration with the Laboratory of Chemical Engineering (INPT). Using a patented process involving the production of hydrogen by catalysis of weak acids, the main scientific objective of the Eco-H2 project will be to develop new electrode materials and a new gas separator. The work will be carried out at the laboratory level and a pilot prototype capable of producing 30 L/h. The target markets are the production of hydrogen for measuring devices in scientific laboratories. This type of technology will eventually be adapted to the Power to Gas market.
