A groundbreaking map of the United States has illuminated the potential locations of substantial, naturally occurring hydrogen reserves. The map, a first of its kind, showcases areas where hydrogen gas could be present beneath the surface in quantities viable for extraction. The revelation challenges previous assumptions, with the U.S. Geological Survey expressing surprise at the vastness of these reserves. Geologic hydrogen, formed through natural processes, could prove to be a significant clean energy source, projected to contribute up to 30% of future energy needs by 2050. The map, color-coded to denote prospectivity, outlines regions with high potential for substantial hydrogen reserves, notably spanning across multiple states including Michigan, Kentucky, North Dakota, Kansas, Colorado, and Iowa. It highlights 30 U.S. states as having the essential conditions for hydrogen accumulation, indicating a transformative shift in the energy landscape. Moreover, the study estimates a staggering 6.2 trillion tons of buried hydrogen reserves across the globe, with a fraction of this holding the capacity to power the world for two centuries. This pioneering research, culminating in the map's publication, heralds a new era in energy exploration, offering a roadmap to unlock the untapped potential of geologic hydrogen. The implications are profound, signaling a promising future with cleaner energy solutions and a heightened focus on harnessing hydrogen for sustainable energy goals. By pinpointing regions rich in hydrogen reserves, the door is opened for targeted extraction efforts, paving the way for a more sustainable and environmentally conscious energy landscape.
