Yep.
Batteries aren't great for super-cold areas. Pure hydrogen, my understanding is that it's pretty much impossible to make a 'leak free' tank. So for things like backup power generation there is an additional challenge. More thinking about need to top off than risks, I'm not qualified to speak to whether such a tank would be a risk.

- fsh 5y agoI don't think that leakage is a serious issue in high-pressure hydrogen storage. The tanks used in hydrogen fuel cell vehicles have leakage rates of a few mL/minute [1]. The first generation Toyota Mirai has a storage capacity of 85000 standard liters of hydrogen. It would take tens of years to leak out a significant fraction of that.
