In the context of the current energy transition, the search for clean and sustainable energy sources is essential to transform the energy system into a more efficient and circular one. In this regard, hydrogen (H2) emerges as a key alternative due to its high energy density and carbon dioxide (CO2)-free production. However, H2 storage faces significant technological challenges in terms of safety, cost and utility. At the same time, urgent strategies are needed to mitigate the CO2 emissions that are constantly generated by different sectors. Adsorption has emerged as one of the most promising technologies for this purpose, using adsorbent materials where gas molecules can be stored safely within their pores or weakly on the surface. However, the greatest challenge in this area is the development of materials that allow for the efficient storage of these gases while minimising the environmental impact of their synthesis routes. In this context, this proposal aims to develop porous materials, such as nanostructured carbons (NC), Metal Organic Frameworks (MOFs) structures, and hybrid materials. For this purpose, emerging techniques such as mechanochemistry will be used, using agro-industrial waste from the Extremadura region and plastic waste, such as polyethylene terephthalate (PET) bottles, as raw materials. In addition, materials will be functionalised to increase their H2 and CO2 adsorption capacity by using natural sources of minerals. It is expected to obtain materials with high specific surface area and high microporous volume which are expected to adsorb high amounts of H₂ and CO₂, providing a feasible, sustainable and technological solution to the problems associated with the storage of these gases.
