Unleashing the Potential: Geological Hydrogen for Future Energy Needs
Key Ideas
- Underground hydrogen reserves could meet global demand for 200 years, aiding in decarbonization efforts.
- Research by USGS highlights the vast amount of hydrogen trapped in geological formations and natural processes.
- Stimulated interest from businesses and investors could lead to more exploration and potential rewards in the hydrogen sector.
- Further drilling is essential to test ideas and establish a feedback loop between field operations and labs.
A recent report from the US Geological Survey reveals the untapped potential of geological hydrogen reserves to address global energy needs. The research indicates that subsurface hydrogen resources could last for almost two centuries, satisfying the growing demand for hydrogen as a clean energy source. Coauthors Geoffrey S. Ellis and Sarah E. Gelman analyze the mechanisms of hydrogen generation and flow in geological formations, estimating approximately 5.6 trillion metric tons of trapped hydrogen. Additionally, natural processes contribute 15-31 million tons annually. Despite uncertainties, accessing a small fraction of these reserves could meet global hydrogen demand for the next two centuries. The findings have garnered interest from the business community, with potential for high rewards for early investors and companies. Morten Stahl of Natural Hydrogen Ventures emphasizes the need for increased exploration through drilling to validate concepts and establish a feedback system between field operations and research labs.
