In one modelled scenario, hydrogen plumes could interact with methane in the air to add 0.4 degrees Celsius to global warming. Minimising leaks should be a policy priority, the study found. Hydrogen leaks twice as bad for climate as previously believed

Why it matters
Leaked hydrogen fuel is 11 times more powerful than carbon dioxide in causing global warming, according to a study released by the United Kingdom government.
That’s more than twice the figure given in previous estimates, which do not fully account for how the lightest gas on Earth interacts with other greenhouse gases in the atmosphere, the report said.
The warning comes amid high interest globally in hydrogen to replace fossil fuels in power plants, transport and industrial systems. Hydrogen produced with renewable energy is widely seen as a low-carbon fuel. While expensive today, costs are expected to drop with better technology later this decade.
