The global objective of decarbonization aims to achieve a sustainable energy future by 2050, combatting issues caused by fossil fuels and emissions like SOx, NOx, and CO2. The urgency to shift from gas and oil towards alternatives like hydrogen for greater energy independence is emphasized. Hydrogen, as an energy carrier, is poised to play a vital role in decarbonizing all economic sectors, aligning with the EU's 2021 Sustainable Growth Strategy. By 2050, hydrogen is projected to account for 14% of the energy mix, overcoming technological hurdles and facilitating large-scale deployment. Hydrogen's versatility through Power-to-X routes allows integration of renewable energies, aiding in system flexibility and decarbonization. Hydrogen's benefits include zero CO2 emissions, high energy density, low activation energy, non-toxicity, and high safety levels. The production of hydrogen varies from non-renewable fossil resources to renewable sources like solar, wind, and biomass, to nuclear energy. Each source impacts the classification of hydrogen colors, from gray to turquoise for fossil resources, green for renewables, and purple for nuclear energy. Effective hydrogen storage, essential for its economy-wide adoption, presents challenges due to its nature and varying storage requirements based on the intended use. Stable storage systems are crucial for decentralized electricity generation and industrial applications.
