Hydrogen Reserves Could Power Earth for 170,000 Years

Scientists report the Earth’s available hydrogen reserves could theoretically meet global energy needs for at least 170,000 years—if extracted and utilized efficiently. Hydrogen produces water when burned, making it an appealing alternative to fossil fuels. However, harnessing these massive reserves requires substantial technological investment and infrastructure. Researchers point out that significant hurdles, from cost-effective extraction methods to safe transport, still stand in the way. Yet the sheer scope of hydrogen’s potential sparks optimism for a net-zero future.
