Natural hydrogen, also known as geologic or white hydrogen, is garnering global interest as a game-changer in the shift towards sustainable energy sources. Unlike manufactured hydrogen, which is typically derived from fossil fuels or renewables, natural hydrogen occurs naturally in the Earth's crust, offering prospects for a sustainable energy revolution. Various geological processes such as serpentinisation, radiolysis, and organic decomposition contribute to the formation of natural hydrogen. Notable discoveries like the borehole in Bourakébougou, Mali, and major reserves in regions like Lorraine and Moselle in France have highlighted the vast potential of natural hydrogen resources globally. In countries like Australia, the USA, and Spain, hydrogen seeps have been documented, showcasing the widespread presence of this clean energy source. India, with its geological structures including ultramafic rocks, ophiolite belts, and sedimentary basins, stands out as a high-potential zone for natural hydrogen. If even a small percentage of global geological hydrogen is recoverable, it could significantly surpass known natural gas reserves and potentially meet global hydrogen demand for centuries. Moreover, the production cost of natural hydrogen is estimated to be lower than that of green or grey hydrogen, making it an attractive option for energy production. The industry is experiencing a surge in interest, with the number of companies exploring natural hydrogen increasing from 10 to 40 in just three years. This global 'hydrogen rush' signifies a shift towards cleaner and more efficient energy alternatives. With its immense potential and cost efficiency, natural hydrogen could play a crucial role in shaping the future of renewable energy and meeting the world's growing energy needs.
