We’re going to need as much carbon neutral energy as possible no matter what. (If only we had somehow invented an extremely plentiful, carbon-neutral energy source in the 1940’s, we might not be in this mess right now….)
Once you get to the hardest marginal cases, I’m not actually sure what the most efficient way of offsetting the carbon emissions of airplanes is. It might actually be more efficient to just capture and sequester enough CO2 to offset the emissions of jet engines than to find a new energy source that works on airplanes.

The remaining carbohydrates in the algae can be turned into ethyl alcohol by yeast, or Acetone/Butanol/Ethanol by the ABE fermentation cycle and the protein can be used for animal consumption, or anaerobic respiration into methane. All of these are suitable fuel sources.
