The development of storage systems that could manage the fluctuations of the energy production from intermittent renewable sources (solar and wind) is a fundamental element of the energy transition. In particular, with the electrification of the different industrial sectors, research on Power-to-x technologies is growing extensively. Thus, electrolysers, which can be employed to balance the overproduction of electricity from renewables by exploiting them for the production of green hydrogen and chemicals (like light olefins), are being largely studied and commercialised. The importance of light olefins in today’s world, can be highlighted by their extensive use in chemical industry, where they represent the most important platform molecules for the crafting of different products such as: polymers, solvents, detergents, fuels and additives.
