The US Geological Survey (USGS) has unveiled a groundbreaking map revealing potential geologic hydrogen reserves in the United States, challenging conventional beliefs about the availability of this clean energy source. For years, experts doubted the existence of significant naturally occurring hydrogen reserves for energy purposes. However, the new map released by the USGS suggests otherwise. The study authors estimate that the untapped hydrogen reserves in the US could provide enough carbon-free fuel for the world for 200 years, emphasizing the potential of this energy source. They project that hydrogen could account for up to 30% of future energy supply in certain sectors, with global demand expected to increase substantially by 2050. The map categorizes different states based on their likelihood of containing usable hydrogen, with areas like Kansas, Iowa, Minnesota, Michigan, and certain regions along the Eastern Seaboard identified as potential resources. The USGS researchers developed a new methodology to assess hydrogen accumulation conditions and discovered promising regions for clean energy extraction. While this map represents a significant milestone, further investigations are necessary to fully understand the extraction potential of geologic hydrogen in the US. The discovery opens up possibilities for sustainable energy sources, offering a glimpse into the potential future of energy supply and emphasizing the importance of transitioning to clean and renewable energy sources for a greener planet.
