When scientists analyzed air samples trapped in drilled cores of Antarctica's ice, they found atmospheric hydrogen had increased 70 percent over the course of the 20th century.
Even as recent air pollution laws have sought to curb fossil fuel emissions, hydrogen emissions have continued to surge with no signs of slowing down. And there's a chance that leakage is to blame.
No one has directly measured how much hydrogen leaks from these processes, but initial estimates suggest it could be significant.
They can't be sure this is where the hydrogen is coming from – hydrogen emissions from coal combustion are also seriously understudied – but the authors argue it's worth investigating more.
Especially since green hydrogen processes, which split hydrogen from water to create carbon-free power, could also result in substantial leakage if they are one day scaled up, as some climate scientists and environmentalists hope they will be.
If hydrogen one day leaks from industrialized hydrogen gas plants,
experts are troubled it could increase the lifetime of methane in our atmosphere, a greenhouse gas 20 times more potent than carbon dioxide.
