The current needs for decarbonization have placed hydrogen and hydrogen-enriched fuels as an efficient solution for the transition to a clean, low-carbon energy system. Nonetheless, reducing the emissions and the carbon dependency to the levels of the EU targets brings new challenges to the energy-intensive industrial processes like steel manufacturing or power generation. The development of power-to-X (P2X) technologies can be used to produce hydrogen from renewable electricity referred as “green hydrogen” and supply the fuel demands of such processes reducing the carbon-foot print and the fossil...
