H2CORK - Produção de Hidrogénio por via termoquímica solar usando Ecocerâmicas obtidas a partir de cortiça


Sustainable alternatives to fossil fuels, such as H2, are urgently needed, and must be produced using renewable energy to be truly sustainable. Concentrated solar energy (a focused beam of sunlight) can be used to produce electricity, split water or create synthetic fuels without CO2 emissions. H2 production via direct solar TCFP should be more efficient than electrolysis using solar electricity, and so is an innovative solution to H2 production. What is required is a suitable material for a TCFP catalyst. It is known that CeO2-based materials can be used to split water and produce H2 for TCFP, via a redox cycle that requires heating up to 1400 ºC. What is required is further development and optimization of such materials in order to improve efficiency, redox reaction rates and heat resistance through the cycles, to lower the operating temperatures needed, and to enhance their microstructure/surface area. Any materials solutions should also be based on renewable/ sustainable resources and methods. H2CORK will develop novel CeO2-based ecoceramics, exploiting the regular, highly porous microstructure of sustainable cork templates, for the innovative renewable production of hydrogen via direct solar thermochemical fuel production (TCFP).
