Microalgae-based biofuel can help to meet world energy demand, researchers say

Microalgae-based biofuel can help to meet world energy demand, researchers say | Algae | Scoop.it

Microalgae-based biofuel not only has the potential to quench a sizable chunk of the world's energy demands, say Utah State University researchers. It's a potential game-changer.

 

"That's because microalgae produces much higher yields of fuel-producing biomass than other traditional fuel feedstocks and it doesn't compete with food crops," says USU mechanical engineering graduate student Jeff Moody.

 

With USU colleagues Chris McGinty and Jason Quinn, Moody published findings from an unprecedented worldwide microalgae productivity assessment in the May 26, 2014 Edition of the Proceedings of the National Academy of Sciences. The team's research was supported by the U.S. Department of Energy.

 

Despite its promise as a biofuel source, the USU investigators questioned whether "pond scum" could be a silver bullet-solution to challenges posed by fossil fuel dependence.

 

"Our aim wasn't to debunk existing literature, but to produce a more exhaustive, accurate and realistic assessment of the current global yield of microalgae biomass and lipids," Moody says.

 

With Quinn, assistant professor in USU's Department of Mechanical and Aerospace Engineering, and McGinty, associate director of USU's Remote Sensing/Geographic Information Systems Laboratory in the Department of Wildland Resources, Moody leveraged a large-scale, outdoor microalgae growth model. Using meteorological data from 4,388 global locations, the team determined the current global productivity potential of microalgae.

 

Algae, he says, yields about 2,500 gallons of biofuel per acre per year. In contrast, soybeans yield approximately 48 gallons; corn about 18 gallons.


"In addition, soybeans and corn require arable land that detracts from food production," Quinn says. "Microalgae can be produced in non-arable areas unsuitable for agriculture."

 

The researchers estimate untillable land in Brazil, Canada, China and the U.S. could be used to produce enough algal biofuel to supplement more than 30 percent of those countries' fuel consumption.

Here's a way to produce biofuels that does not compete with food production.

Daniel LaLiberte's curator insight, May 29, 2014 8:52 PM

Land that is not used for food can be used to produce algae-based biofuel to meet a large fraction of the world's energy needs.  But another alternative is vertical farming in urban areas, where we can create as much space as we need.  

Eric Chan Wei Chiang's curator insight, May 30, 2014 2:50 AM

This study highlights the commercial viability of algae biofuels.


The game changing aspect of the technology is that it does not contribute to food insecurity http://sco.lt/5CifIH, a global issue aggravated by climate change http://sco.lt/86HUtl.


However, would we garner enough political will to wrest monopoly from oil and gas companies?

P A L M A R I A P A L M A T A is a cold water algae species that is found in the middle to lower shore in many parts of Europe and the North Atlantic Coasts of America.
CCRES's insight:
CCRES FUCUS was sequentially extracted with water at 22 °C (fraction 1 (F1)) and 60 °C (F2), and with 0.1 M HCl (F3) and 2 M KOH (F4) at 37 °C. Soluble fractions (42.3% yield) were composed of neutral sugars (18.9−48 g/100 g), uronic acids (8.8−52.8 g/100 g), sulfate (2.4−11.5 g/100 g), small amounts of protein (<1−6.1 g/100 g), and nondialyzable polyphenols (0.1−2.7 g/100 g). The main neutral sugars were fucose, glucose, galactose, and xylose. Infrared (IR) spectra of the fractions showed absorption bands at 820−850 and 1225−1250 cm-1 for sulfate. F1, F2, and F4 also exhibited an absorption band at 1425 cm-1, due to uronic acids, and their IR spectra resembled that of alginate. F3 had an IR spectrum similar to that of fucoidan with an average molecular weight of 1.6 × 106 Da, calculated by molecular exclusion high-performance liquid chromatography. The presence of fucose in this polysaccharide was confirmed by 1H NMR spectroscopy. This fraction showed the highest potential to be antioxidant by the ferric reducing antioxidant power (FRAP) assay, followed by the alkali- and water-soluble fractions. Sulfated polysaccharides from edible seaweeds potentially could be used as natural antioxidants by the food industry.

Low Oil Prices Not Killing Algae Biofuel — Yet

Low Oil Prices Not Killing Algae Biofuel — Yet | Algae | Scoop.it
The global petroleum price crash is putting the squeeze on biofuels, but new research projects keep algae biofuel on the path to competitiveness.
CCRES's insight:

The algae biofuel market is still in play even though the global petroleum market shows no real signs of lifting itself out of the doldrums, as two examples from different ends of the Earth illustrate. Over in Australia, researchers have come up with a new, low cost way to raise algae for biofuel, and here in the US the Department of Energy is moving forward with a new grant program to fund commercially viable algae production.

CCRES's insight:

Scientific American tells the story of Bren Smith, owner of Connecticut-based Thimble Island Oyster Company, and director of the organization Greenwave, who started growing kelp and shellfish as a reaction to several crises he faced in his own life: overfishing, climate change, and rampant unemployment in the fishing industry. He was working on the Bering Sea when the cod stocks crashed, and he lost oyster crops to both ocean acidification and two hurricanes. Based in part on the research of Dr. Charles Yarish at the University of Connecticut, Smith’s 3-D ocean farming model uses the entire ocean column to grow as many different foods as possible in as small an area as possible.

Qualitas says drawbacks of open pond algae cultivation easily dealt with | Algae | Scoop.it
Qualitas Health, a supplier of a unique polar-lipid structured algal omega-3 ingredient, is now at full scale production and is participating in what an executive calls “the future of omega-3s.”
CCRES's insight:

We grow the algae in open ponds, so sunlight is the source of energy. It is an agricultural technology, so you are at the mercy of the elements. But there are ways to mitigate that by holding inventories of different intermediates, whether it is the harvested algae or the extracted oil.

CCRES's insight:

Photosynthesis uses light from the sun and carbon dioxide from the air to make chemicals that can be converted into energy-rich biofuels. Plants, however, transform less than five percent of the solar energy they capture into harvestable chemical energy. The New Mexico Consortium and Los Alamos National Laboratory are working on strategies to improve the energy yield in algae and plant systems, resulting in more fuel in our tanks and more food on our plates, without releasing additional carbon into the atmosphere. Dr. Richard Sayre tells the story.
