Comment on Engineering Breakthrough Opens Door to Cheap Hydrogen Power

• kersploosh@sh.itjust.works ⁨1⁩ ⁨month⁩ ago

  There are two practical ways to make hydrogen:

  1. Split water molecules via electrolysis. This is thermally inefficient and not cost-effective at scale.

  2. 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.

  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.
