I think the 1st pair of articles is more addressed to your skepticism. I recommend them -- they are not merely boosterism. The author provides a thorough rebuttal of the hype around hydrogen for cars & home heating. 'Blue' and 'grey' hydrogen (from fossil fuels with or without carbon capture) are addressed. The upshot is that carbon tax would be necessary to shut 'grey' hydrogen out. After that, initially 'blue' hydrogen would win on cost, but 'green' hydrogen could eventually become cheaper.
