A new group of scientists just started the Hydrogen Science Coalition to bring evidence based arguments to the hydrogen discussion. It's a great resource to help fight the hydrogen lobbying going on around the world. Many O&G companies are pushing for hydrogen because it would allow them to keep operating their businesses, but much of it is a delay tactic and completely disregards the continued GHG emissions that would then come with it. Their 4 key recommendations:
1)The only zero emissions hydrogen is green hydrogen
2)Hydrogen shouldn’t delay existing electrification solutions
3)We need to decarbonise grey hydrogen first
4) Blending hydrogen into the gas grid is a waste
