"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, online Early 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.
"Our results were much more conservative than those found in the current literature," Quinn says. "Even so, the
numbers are impressive."
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.
"That's an impressive percentage from renewable energy," Moody says. "Our findings will help to justify the
investment in technology development and infrastructure to make algal biofuel a viable fuel source."

tommo
3 / 5 (2) 19 hours ago Have worked on using algae to purify wastewater with the intended consequence of gaining the
biodiesel for years now, the priority is recycling the water and algae clean water really well so
make that possible rather cheaply compared to using chemicals. The need is the time it takes is
about 2.5-days so requires photo-bioreactors to grow 24x7 and insulated to work in the Arctic in
winter for towns there, ponds don't work. Since these can be small and stacked they take up less
land footprint and better conservation of heat, everything is piped in.
It's a good idea, Phoenix, AZ, produces 10-million gal/day in effluent, that's 20,750-tons daily in
algae nutrients and worth about 3-million gal/day in biodiesel and you get the 10M gal/day of
water back.
This estimate uses Spirogyra, very common species and only 11% oil ... so conservative on
production output, easy to grow. There are many ways now to harvest and process the algae for the oil, refining & tweaking that for use in vehicles.

Hemp is a much more practical biofuel. It outproduces pretty much everything else and produces both biofuel
mass as well as pure oil. It has been shown to be able to replace pretty much all plastics and building materials.
Hempcrete is carbon negative and gets harder and more solid over time. We already have the technology for a
hemp based biofuels industry and the only thing stopping us is Big Oil, Big Pharma, and the DEA.

Biofuels are one of the tri-ad of a renewable zero carbon energy system; Biofuels. wind and solar. Of the
biofuels, I see the Algae engineering as on of the most promising of the sources of for replacements to oil
chemistry. There are already promising replacements for Jet Fuel from Algae. Similarly, big equipment that runs exclusively on diesel could be carbon neutral just by using Algae. If America's total supply of diesel was derived
from Algae, a large portion of CO2 production would be neutralized.
Algea farming is an excellent idea, one whose time has come.

We haven't beaten nature at it's own game during the thousands of years of domesticating plants and animals.
Most of the organisms we have created fail miserably when released into the wild, or quickly revert back to their
original forms. Nature has had millions of years to try countless combinations, and you believe we can somehow
better that?

It's like with all the biofuel (and, indeed, all renewable sources of energy)... we need to stop thinking in overly
simplistic terms of "there's one singular source that will solve all our problems".
It's going to be a mix for the foreseeable future and it's going to require a bit of finesse to integrate that mix into a working whole. But it's not like we lack the brainpower (or the economic ability) to do it in a relatively short
time.
So anyone who argues that technologies (like the one presented in the article) aren't good enough to supply all
our needs is missing something fundamental in their thought process.
