mainly because it is difficult to distribute and store Untrue. Energy losses in hydrogen storage and transmission are significant (11%) but much smaller than the losses at the electrolysis step (24%) and the redox step (46%).

Hydrogen is largely produced via steam reformation, making it a natural gas powered battery that's shittier than electricity in almost every way.

  That's my point. Hydrogen would still be terrible even without storage and moving problems.

  This is about green hydrogen ( https://en.wikipedia.org/wiki/Green_hydrogen https://en.wikipedia.org/wiki/Green_hydrogen )

This is at best not very pertinent, for many reasons. 1/ Losses vary according to the way the hydrogen is produced then used, and there are multiples paths. Overview: https://assets.siemens-energy.com/siemens/assets/api/uuid:5342163d-2333-4c8d-ae85-2a0e8d45db56/white-paper-efficiency-en.pdf https://assets.siemens-energy.com/siemens/assets/api/uuid:53... Moreover there are ways enabling a very high yield, for example high-temperature electrolysis (some recent gas turbines can be fed with a gas-hydrogen mix, up to 100% hydrogen) 2/ This is about green hydrogen ( https://en.wikipedia.org/wiki/Green_hydrogen https://en.wikipedia.org/wiki/Green_hydrogen ), therefore the electrolysis step is done thanks to electricity over-produced by renewable sources (without burning any combustible no producing any waste). Consequently the total cost of those losses are very low, as not using this overproduced electricity would lead to lose 100% of it.
