Seaweeds have low to no lignins, depending on the species, simplifying fermentation, but galactose production, during fermentation has been a significant problem... www.biofueldaily.com/reports/Seaweed_As_Biofuel_Metabolic_Engineering_Makes_It_A_Viable_Option_999.htmlSeaweed As Biofuel? Metabolic Engineering Makes It A Viable Option According to Jin, galactose is one of the most abundant sugars in marine biomass so its enhanced fermentation will be industrially useful for seaweed biofuel producers. by Staff Writers Urbana IL (SPX) Dec 16, 2010 Is red seaweed a viable future biofuel? Now that a University of Illinois metabolic engineer has developed a strain of yeast that can make short work of fermenting galactose, the answer is an unequivocal yes.

Potential synergy would be ferment for alcohol, use the remainder as feedstock for a digester, making Methane and fertilizer.

If you want to use it as a fertilizer, aren't you restricted only to salt-water plants, because of the salt in the seaweed?

Salt content varies widely, by type. Some seaweeds are very high in Sodium, others fairly low. In an oceanic setting, Halophytic plants will do better than non-halophytes, but each plant differs in how it deals with excess salt, too.
Some Mangroves perspire excess salt through their leaves, and some will actually form salt crystals on the undersides of their leaves. When the wind blows, or rain reaches them, this salt is knocked back into the water below, returning the salt to the environment.
I used to collect Hickory Bark, and boil it, for a natural seasoned-salt.

Salt is not forever. Sodium and chlorine can be separated. NaCl is not the only salt in sea water either. Salts are fairly stable chemical bonds, but can be catalyzed into reactions with other elements through biological or other chemical reactions.

Somewhere in the past decade I saw a patent for a water purifier that separated the Na and Cl ions ... or something like that.
It used an ultra-low voltage (battery, basically) and was a super-slick scheme. But I've forgotten all the details and can't find it now. 😟
