The H2-REnWast project will install an electrolyser at the IPT campus. In order to explore the potential of producing Green Hydrogen, the electrolyser will be integrated with the IPT solar farm (photovoltaic - PV), hydrogen storage and a small fuel cell for re-electrification. For this purpose, in addition to using energy from renewable sources (Green H2), in order to make the process even "Greener", and so as to maximise relevance, wastewater will be used in the hydrogen production process. Thus, the treatment of wastewater is necessary to achieve high hydrogen purity and efficiency of process. The plant will be operated in multiple emulated configurations (energy storage, microgrid, fuel production). Hydrogen is increasingly seen as a very important energy vector, both at European and national level. IPT is part of a working group created by the CIMT to turn the Médio Tejo into a “Hydrogen Region”.
