These articles are always missing the important numbers:
What is the conversion factor between electricity->hydrogen->electricity?
How much does storing hydrogen cost per kwh?
What is the density of that storage? Per kg or m^2?
What is the leakage rate for that storage? (hydrogen is tiny so tends to leak out of containers)
How much does a the hydrogen producer cost per KW? The hydrogen consumer?

- midasuni 4y agoabout 75% but potentially could increase to over 90% [0] Doesn’t feel too bad to me, especially how cheap renewables are. [0] https://newatlas.com/energy/hysata-efficient-hydrogen-electrolysis/ https://newatlas.com/energy/hysata-efficient-hydrogen-electr...
- miketery 4y ago> hydrogen is tiny so tends to leak out of containers I'm not a materials person, so please point out the error the following thought experiment. Use a cylindrical vessel with an opening at the bottom. Fill with hydrogen, then fill with a liquid that is heavier than hydrogen (so it sits at the bottom), then plug it. Hopefully the heavier liquid is less "leaky". Would this work?
