A recent study published in Science Advances sheds light on the potential of vast underground reserves of natural hydrogen as a sustainable energy source. These reserves, estimated to be around 6.2 trillion tons, exceed global oil quantities by 26 times. Despite the immense potential, challenges in accessing these reserves due to their depth and location exist. However, even harnessing a small fraction of these reserves could power the world for 200 years and aid in achieving carbon neutrality. Natural hydrogen, formed through geological processes, stands as an environmentally friendly alternative to traditional fossil fuels, as it is self-generated and naturally stored. Researchers are actively working to refine geological criteria to effectively locate and extract these reserves, aiming to transform the global energy landscape. While uncertainties remain regarding quantities and accessibility, the study's findings indicate a promising outlook for a sustainable energy future driven by natural hydrogen. Continued research and advancements in this field are expected to provide further insights and possibilities by 2024.
