Honestly not really. Insolation energy is not that high, and photosynthesis tops out at around 10% under best conditions, and that's energy out the end of photosystem (solar cells are pushing 30% and perovskite might go to 40 or 50%), so doesn't take into account inefficiency in your sugar (much less hydrocarbon) conversio. The care and feeding of algae is annoying, they grow really slowly so contamination is a constant problem, and they self-shade, so the suface area to volume of growth conditions must be high. And a high surface area means awful evap problems... The list goes on

None of those things change the fact that you're growing your own diesel, which is really cool
