Hydrogen beneath our feet
As a clean energy source, hydrogen has shown to have a lot of potential. But when generated using fossil fuels, hydrogen production can have a large environmental impact—even if the energy source itself doesn’t generate emissions. So, what if we can get readily available hydrogen from the ground instead? Brad Hager, a professor of earth, atmospheric, and planetary sciences at MIT, explores the potential of geologic hydrogen, looks at some of the possible pitfalls, and asks what it might take ...
