coli bacteria, which can feed on the sugars found in brown seaweed and transform the sugars into ethanol. And ethanol production requires that consumption of sugar. To make biofuel, sugar must be fed to bacteria, which transform the sugar to ethanol.

Edible seaweed, also called sea vegetables, are aquatic plants known as algae (either red algae, green algae, or brown algae) that grow in the ocean. Seaweed contains amino acids called glutamates which have a salty, rich, savory taste known as umami.

Most dried seaweed must be soaked before eating. Nori is a notable exception. Soak dried seaweed in a large bowl of warm water until it is tender. Most seaweed will only take a few minutes to become tender and dulse becomes tender so quickly that you only need to run it under warm water.

Seaweed is highly SUITABLE for biofuel. Between 85 and 90% of seaweed is water, which means seaweed is very suitable for biofuel-making methods like anaerobic digestion to make biogas and fermentation to make ethanol. In addition, seaweed doesn’t need fresh water or fertilising.

Like all living things, seaweed needs to stay hydrated to survive. As non-vascular plants, seaweeds lack the true leaves, stems, roots and internal vascular systems most other plants use to take in water, so they absorb it through the surface of their leaf and stem-like structures.

Seaweed is an increasingly popular ingredient in cuisines all over the world. It’s the best dietary source of iodine, which helps support your thyroid gland. It also contains other vitamins and minerals, such as vitamin K, B vitamins, zinc and iron, along with antioxidants that help protect your cells from damage.

Brown macroalgae as the 3rd generation biomass is now being considered as a renewable biomass for production of biofuels and bio-chemicals (John et al. Brown macroalgae as the 3rd generation biomass is now being considered as a renewable biomass for production of biofuels and bio-chemicals (John et al.

Once the algae are harvested, the lipids, or oils, are extracted from the walls of the algae cells. There are a few different ways to extract the oil from algae. At this point, carbon dioxide is mixed with the algae. When they’re combined, the carbon dioxide turns the algae completely into oil.

The production cost is high because of the energy required to circulate gases and other materials inside the photo bioreactors where the algae grow. It also takes energy to dry out the biomass, and Solix uses far less water than other companies (see Cutting the Cost of Making Algae by 90%).

Algae biofuel is unsustainable and/or non-economically viable. For at-scale algae or other biofuel potentials that depend on finite critical resources, there really isn’t any foreseeable potential.

Algae production consumes more energy, has higher greenhouse gas emissions and uses more water than other biofuel sources, like corn, switch grass and canola, Clarens and his colleagues found by using a statistical model to compare growth data of algae with conventional crops.
