Algae could work rather better than most biofuel alternatives 'cause they will sustain quite a bit of industrial abuse, meaning you can dump fertilizer and not worry too much about “exhausting” basins. Downside is that the yield of energy out of a volume of grown algae is simply very low compared to pretty much every other plant form (algae containing very little energy reserves).

OTOH, hydrogen has the benefit of being able to produce relatively large volumes from small facilities, and also of having a very high energy yield from a small volume to begin with. So the logistics are easy: just grab a standard off the shelf (nuclear powered) generator, and wire it up. Downside is high yield to the point that roofs may be blasted from buildings given even a relatively small leak.
