I just saw this reportabout green algae in Brittany.
It suddenly makes me think that there would be only to collect them, wash, compress, dry to make an additional fuel.
A bit like advertising paper briquettes. Except that there are tons available, easily.
Of course, that does not solve the problem of excess nitrates, as paper briquettes do not solve the problem of excess ads in mailboxes. But at least it would save a few horses ... by avoiding using another energy.
What do you think?
Auxiliary energy by green algae in Brittany?

Direct fuel I do not know (PCI? Density? Then it stinks no?) But source of biomass for biofuel or biogas it seems interesting to me ... see quite simply (it is already the case) fertilizers in direct spreading. ..

all biomass contains energy: the problem is that when it contains too much water it is worth nothing as fuel: to dry it it will require more energy than it can produce
the worst part is that if it wants to ferment no matter how it will be destroyed before making a fuel
the solution may be in anaerobic digestion: rather than trying to dry the wet biomass, let it ferment and make methane
it does not only make H2S but especially CO2: if it were in tanks without oxygen it would mainly make methane with a little H2S too, but this is not a problem: the lake gas also contained H2S : it was a wealth: we made tons of sulfur

Green algae in Brittany
The green algae picked up as they arrive on the beach is not a problem. Once put in bulk blocks by the municipal services the fermentation without air occurs with production of sulfur gas and other.
A company (OLMIX of Pledran 22) has a project to methanize green algae but with the financial crisis difficult to find finances.
Methanization of biomass, whatever its origin, is underway and developing.
And if the pig producers and the cities methanize 100% of organic matter the problem of nitrates and green algae solved. But once again treat the cause and not the blame

of course avoid polishing and leaving the sea clean would be best
but since the damage is done, it is necessary to spend to clean up, rather than spending to pile up anywhere and polish a little more, these green algae could participate in the feeding of a methanizer also used for something else

What about solar drying? I think it is still the drying most used by humanity in 2009!

drying consumes energy: if this energy is solar it looks better, but it is not free and easy so far: especially for something that has more desire to rot than to dry: if drying is not fast enough it won't do any good
the advantage of anaerobic digestion is that you can immediately swing everything in a large tank and you just have to wait for the gas
in addition if it makes H2S is that it contains sulfur, which will pollute by burning
with methanization it is possible to purify the gas to remove the sulfur and not burn it: the sulfur is an additional benefit for a good gas plant

I have already tried to simply dry certain waste in the sun: the problem is that it only dries in summer and that it is in winters that solid fuel is needed for heating
dried waste is very difficult to store properly for the winter
the advantage of metanization is to recover with the minimum of work: it makes gas having all kind of use even in summer
huge methanizers can even do seasonal storage: lower the temperature in summer to slow the methanization and make less gas therefore accumulate organic matter
increase the temperature in winter to make more gas and use what has accumulated in summer
