Just listened to a BBC pod
Grey, Blue and Green Hydrogen.
At the moment we overwhelming have Grey Hydrogen. Methane extracted from under the Earth, Methane used to make electricity. Methane used as a feedstock to extract Hydrogen, releasing Carbon dioxide into the atmosphere.
The question seemed to be, would boiling a kettle of water at home, by using Blue Hydrogen be any less detrimental to the atmosphere than just using Methane to boil the water.
The answer was: It was less damaging to the atmosphere, to burn Methane at home to boil a kettle of water, than either using Methane to make electricity, then using electricity to boil water at home, or using Methane to produce Hydrogen, then burning Hydrogen at home to boil a kettle of water.
The scientist claimed under all options it was better just to use Methane.
Perhaps he will tell our government?
