Hydrogen is a strong indirect greenhouse gas.
The climate impact of hydrogen is about 34 times higher than CO2 when measured over a 20-year period. Looking at the impact over 100 years, the global warming potential reduces to between eight and 13 times.
Hydrogen causes this by stabilising methane in the atmosphere and creating tropospheric ozone and stratospheric water vapour.

We shouldn't be having methane in the atmosphere in the first place. Sure, if you produce the hydrogen from natural gas then you have a problem because that stuff comes with plenty of methane which won't suddenly stop leaking.
Ha. So we are banning farmers from owning livestock
Also if you inject hydrogen into the existing natural gas pipeline.
The point here is that hydrogen leaks are very much an issue. Your previous statement was false.
Noone here is planning to inject hydrogen into existing pipelines. If anything, synthesising methane during the transition so that consumers only have to switch their burners once, from nat gas to hydrogen, and not first to nat gas + more hydrogen and then to pure hydrogen. Gotta switch whole municipalities at once doesn't make sense to duplicate the last-mile gas pipes. If, and that's not even clear yet, hydrogen pipes will even be a thing for private consumers.
Ok. Not you. But lots of people elsewhere in this thread.
Agree. Burning hydrogen has to be done carefully to avoid NOx and other side effects.
Agreed.
Industrial green hydrogen is a necessity to remove fossil fuels. Residential hydrogen I am very sceptical about. Even 100% clean fuel cells burn too hot for domestic heating.
