How is the hydrogen made?

𝒎𝒂𝒏𝒊𝒆𝒍@sopuli.xyz · 7 个月前

I thought it’s made through electrolysis

You can, but it is totally inefficient

You get about 30% of the energy out that you put in

So it’s more like a really bad battery

But with all the disadvantages of having to handle gas!

Yup! It has really good gravimetric energy density, but really bad charging efficiency.

Not THAT bad, really, it potentially has a much better mileage-to-weight ratio and sidesteps the issue of lithium recycling and politics

Great to gravametric energy density, okay volumetric energy density, great availability, terrible charging efficiency, and complicated handling and storing mechanisms. Lots of tradeoffs.
