This video contains some silliness, but does at least demonstrate the possibility.

Hydrogen fuel cells can be expensive and storing power in batteries has various drawbacks.
I could see a Stirling engine / Hydrogen energy system being practical under some circumstances.
Stirling engine / Hydrogen storage system
Re: Stirling engine / Hydrogen storage system
This proposed DIY method of "safe" Hydrogen storage is, apparently do-able but also probably a bit more difficult than it sound in the video from what additional research I've been able to do.
For example, apparently the substance needs to be vacuum dried and then cycled several times before it actually works. That is, the vacuum helps open the pores, then hydrogen gas needs to be forced into it under pressure and released by heating a few times to get the stuff broken in and working well.
I have a kiln, vacuum pump, some cylinders, and just founds some bags of urea at the local garden shop so thought I might give this a try.
I'm adding it to my long to-do list anyway.
