Earth may contain vast overlooked stores of hydrogen gas. If some of it is feasible to recover, this natural hydrogen could provide a source of clean-burning fuel that might accelerate the transition away from fossil fuels and last for centuries.
Geologists have known for decades that millions of tonnes of hydrogen gas generated by natural geological processes seeps out of the ground every year, but it wasn’t seen as a viable source of energy.
Most geologists assumed the tiny hydrogen molecules wouldn’t stay …
