The global energy system is undergoing a significant transformation, driven by the need to reduce greenhouse gas emissions and transition toward renewable energy sources such as wind and solar power. One of the key challenges in this transition is the intermittency of renewable energy, which requires large-scale, long-term energy storage solutions that has become a critical requirement for balancing energy production and demand. \\ Hydrogen is increasingly recognized as a truly key energy vector (for storing renewable energy) in the transition to a low-carbon economy by many domain experts and some of the major Energy companies. However, large-scale storage remains a significant challenge due to hydrogen's low energy density and its physical and chemical properties.
