Algae doesn’t capture it for long.

Not true, it depends on how it's contained. Drying algae and removing the water will stop it from decomposing. Think of seaweed used for sushi except ground up into a very dense powder. Algae will decompose if left hydrated in the sun though.

Where you getting the energy to capture and dry algae that results in a total positive capture?
