The process cannot be carbon negative unless you sequester the algae somehow. All the carbon the algae captures while growing will be released when they decompose.

Hmm could be that the way is co2->algea->hydrocarbon->H2 and carbon as a byproduct.

Still I dont think its Carbon negativ because they rather make hydrocarbons out of it and the production uses energy plus. Only wanted to state the possibility of Carbon negativ as real.

It works out carbon negative because pieces of algae fall down to the ocean floor and remain there, as a side effect of algae cultivation. It's a significant number.
