A new study shows Earth may hold an untapped energy source — trillions of tons of hydrogen gas buried deep beneath the surface.
Best of all? It could power the world for centuries on end.
According to research led by Geoffrey Ellis of the U.S. Geological Survey, these hidden reserves could provide enough energy to reduce global reliance on fossil fuels for 1,000 years.
Formed naturally through geochemical processes, this geologic hydrogen is estimated to total around 6.2 trillion tons (5.6 trillion metric tons), with significant potential to serve as a low-carbon energy resource.
While hydrogen reserves have already been identified in places like Albania and Mali, researchers believe similar deposits exist worldwide. However, much of this hydrogen is likely buried too deep or located offshore, making large-scale extraction a challenge. Even so, the study, published in Science Advances, suggests that tapping into just 2% of the estimated reserves could meet the world’s hydrogen needs for 200 years, helping achieve net-zero carbon goals.
The energy contained in these reserves exceeds that of all proven natural gas deposits, highlighting the potential of hydrogen as a clean alternative. However, experts like Prof. Bill McGuire of University College London warn that developing the infrastructure to extract hydrogen at scale would require a massive global effort. Despite these challenges, the study underscores the need for further research into geologic hydrogen, which could play a critical role in the transition to sustainable energy

Should read massive amounts of money. Again we need to spend huge amounts of money that will eventually be passed on to the end user.
The case for nuclear energy just keeps getting better.
