I mean maybe not even powergen. Store it in the arctic where the population is low, people are unlikely to stumble across it, and then use the latent heat to heat homes or greenhouses or something. Also, I don't think seismically active and things like flooding/hurricanes aren't a thing. If the containers can keep their integrity, why not? If if not enough to fully heat homes/water/whatever, it would at least reduce the need for other sources. Of course this all depends on if the stuff can be stored safely -- and I think that's mostly solved?
