This is the problem algae farms all run headlong into: sunlight density. The energy output you get from doing anything with the biomass can't exceed the received sunlight energy times the photosynthetic efficiency of your microorganisms. And that efficiency might not be as good as solar cells.
The way this process does an end-run round that with added hydrogen is interesting, though.
- pfdietz 5y agoI think algae farms are actually CO2 limited. Even a corn field, in calm air and bright sunlight, runs out of CO2 in about five minutes. And plants like corn have all those leaves above the ground for lots of mass transfer. (Transfer of turbulence to ground level may be a way wind turbines can increase agricultural yield, I think.)
