The development of natural hydrogen (also referred to as geological hydrogen or white hydrogen) has attracted growing scientific and industrial interest as a potentially substantial and sustainable energy resource due to its clean combustion profile and natural occurrence in geological systems. Hydrogen is progressively recognized as a critical energy vector during the transition to sustainable energy frameworks. As an environmentally benign energy vector, H2 possesses the capacity to substantially diminish greenhouse gas emissions when utilized as a fuel. Its classification into three distinct categories, green, blue, and white, reflects diverse production methodologies, each characterized by unique processes and environmental footprints.
