I think it is tricky to contain, being so small, that storage is a big part of why it’s too expensive.
Comment on Engineering Breakthrough Opens Door to Cheap Hydrogen Power

The cost of hydrogen is not the fuel cells but that hydrogen is made from oil.

Huh? I thought Hydrogen was usually produced from splitting O2 and H1 from water?

There are two practical ways to make hydrogen:
Split water molecules via electrolysis. This is thermally inefficient and not cost-effective at scale.
Strip hydrogen atoms off of hydrocarbon molecules, usually natural gas. It’s much cheaper. Unfortunately, the leftover carbon atoms leave the process as CO2. AFAIK all commercially available hydrogen is made this way.

Damn, thanks for the info, I always assumed it was just splitting water

There is a multitude of ways to make hydrogen and only 1% of production is low emission.

Well shit Today I learned, thanks!

It takes a ton of energy to split water into it’s components, that typically comes from fossil energy

Most of it, yes.
But there is no requirement to do it that way.
