Oops, looks like the blue hydrogen producers need to be way more green, and they're sorta stuck in a corner.
At the COP26 environmental summit, a study released says that hydrogen production from natural gas produces a whole host of deadly emissions, like methane.
What's more, the carbon capture process employed doesn't even help much.

It’s hailed as the clean energy of the future. But hydrogen produces ‘substantial’ emissions, study shows

“Hydrogen made from natural gas leads to more fugitive emissions — methane that is leaked into the environment during the extraction and processing of natural gas — compared to just burning natural gas directly,” said Fiona Beck, from the Australian National University, who co-authored the peer-reviewed paper. “Including [carbon capture and storage] in the process actually increases fugitive emissions further, as more natural gas is needed to fuel the process.”
