Couldn't you get carbon credits or whatever for this?

  No idea how reliable or good that revenue source is now, or in the long term. I wonder how hard it would be to make such an "algal mat". I would use something like this around here on my little farm/vineyard even as a kind of weed block, alternative to "plastic mulch": rolls of algal-produced fibrous mats, 2" or so thick. Permeable so water and air can get through, but thick and tight enough that weeds get blocked out. Would just degrade or be tilled into soil over time. There's already equipment out there for laying "plastic mulch" but the stuff itself is fairly controversial because even the biodegradable stuff is still a plastic. If one could economically produce such a thing made out of algae, and compete with plastics on cost, that would be pretty damned nifty. That and just some kind of bulk powder that can be soil incorporated as a carbon amendment. Pay farmers to lay the stuff down in huge quantities as a way of improving soil while getting CO2 out of the atmosphere. Even better if a bioreactor and related equipment to make this stuff could be made to operate locally on site.

    For what it's worth, I worked for a company making an algal soil amendment, and we would distribute it as a suspended biomass (green water).
