Hydrogen plays part in global warming: study
Rising hydrogen emissions from fossil fuels and industrial leaks extended methane's atmospheric lifetime, adding 0.02C to global warming since 1990, study finds.
- On Wednesday, the Global Carbon Project warned hydrogen emissions rose between 1990 and 2020 and contributed 0.02C to the 1.5C warming since the pre-industrial era, Nature found.
- Evidence points to emissions from fossil fuels, livestock and landfills, plus leaks from industrial hydrogen producers and production methods using natural gas and coal.
- Chemically, the two molecules interact because methane generates hydrogen when it breaks down, and `More hydrogen means fewer detergents in the atmosphere, causing methane to persist longer and, therefore, warm the climate longer,' said Zutao Ouyang.
- Despite enthusiasm for 'green' hydrogen, Stanford University scientist Rob Jackson said, `We need a deeper understanding of the global hydrogen cycle and its links to global warming to support a climate-safe and sustainable hydrogen economy.'
- As hydrogen use grows, the study raises a pressing policy debate as international policy makers and regulators stress scaling renewable-powered electrolysis and cutting leaks by industrial producers.

Hydrogen is regarded as an important component of the energy transition. But also the supposedly climate-neutral energy source indirectly promotes climate warming: it delays the degradation of the greenhouse gas methane in the atmosphere and also influences cloud formation. A study has now quantified the hydrogen emissions and sinks since 1990. Important sources are therefore the decay of methane as well as – clearly [...] The contribution hydro…
