Is Algae Biodiesel the Next Big Fuel?

This month algae as a fuel source made the news several times. Last week, Sapphire Energy announced it received $100 million to help reach its goal of making commercial amounts of algae fuel in three to five years. Investors included Bill Gates investment company, Cascade Investment, LLC. In June Sapphire received $50 million from investors.

At the beginning of the month, Arizona State University (ASU) announced its partnership with Heliae Development, LLC and Science Foundation Arizona (SFAz) to develop a kerosene-based jet fuel derived from algae. Last year ASU researched using algae as jet fuel, in conjunction with UOP, a Honeywell company.

Seven days later Solazyme Inc. announced it produced the first algae-derived jet fuel. To date, the company is the only one that has produced fuels that passed specification testing.

In January Solazyme introduced the world’s first cars to run on algae biodiesel at the Sundance Film Festival during the premiere of the documentary Field’s of Fuel. Watch Solazyme’s video about the making of algae biodiesel:

“Five years ago, we could not find a single venture capital firm that had ever heard of the concept of a biofuel,”� Harrison Dillon, president and chief technology officer of Solazyme, told PBS' NewsHour last spring.

Times have changed, and now venture capitalists are banking on algae biodiesel as the next big fuel. The claims made by Green Chip Stocks (GCS) about algae are a good example. In a report, GCS claims that algae biodiesel could “supply all U.S. diesel power using a mere 0.2 percent of the nation’s land.”�

“Venture capital in energy has reached a critical mass,”� said Daniel Yergin, energy historian and consultant. “Enough is happening so that significant things will come out of this. With the same intent to do in energy what they did in biotech, they bring not only money and discipline, but they are results-oriented.”�

"Algae have the potential to produce a huge amount of oil," said Kathe Andrews-Cramer, the technical lead researcher for biofuels and bioenergy programs at Sandia National Laboratories, in Albuquerque, NM. "We could replace certainly all of our diesel fuel with algal-derived oils, and possibly replace a lot more than that."

“If the U.S. put 15 million acres of desert into algae production, we could produce enough volume of liquid fuels to get us off the Middle East oil addiction and give Iowa back to the songbirds,”� said B. Gregory Mitchell, algae research biologist at the University of California, San Diego.

The fastest growing plant in the world, algae does not require farm land or potable water. Since algae absorb carbon dioxide as they grow, algae fuel is considered to be ”�carbon neutral.’ A non-food source, algae is a better fuel source than food-based ethanol. According to Qiang Hu, an ASU researcher, “There is no inherent conflict of using food crop plants for fuel rather than for food.”�

In the 1970s the Carter administration began what was then called the Solar Energy Research Institute, and then consolidated all energy research under the Department of Energy. The Aquatic Species Program began in 1978 to research the production of biodiesel from algae. The Clinton administration discontinued the program in 1996, and two years later the DOE compiled their research into a report.

According to the DOE’s report, during the program’s 18 years, “tremendous advances were made in the science of manipulating the metabolism of algae and the engineering of microalgae algae production systems.”�

I think algae is the way to go. We already have plenty of warm water sources from power plants and factories. It is just a matter of setting up the oil factory and getting the right algae to grow.

I am studying different aspects of this process for a few of my classes right now and I am hoping to retrofit two open pond sites to grow algea for fuel..this winter i will be experimenting with aquariums

Cool, sounds like an interesting project. Goodluck with it.:thumb:

Saw a show on History channel I think a month or so ago and they were talking about a new type of seaweed that developed and was growing uncontrollable. Seems scientists were worried that it would kill everything in the ocean. They said it grew very fast also. Too bad we couldn't harness this stuff for fuel.

you could, theoretically, harvest it and burn it in biomass power plants.....we have one in our area that is trying desperately to get off the ground and they will burn wood chips, and recycled (clean) building materials

the problem is not growing ......... its efficiently giting the oil out of the algae
oil pressing olny gits 30-50%
solvents extraction git 90+% of the oil (unfortunate is the best option so far) but can be pricey and toxic to work with
super critical fluid extraction ... pricey and technical. generally good for lab work
ultrasonic extraction.. pricey equipment and technical
there are 2-3 more methods but its just for lab testing

i have been keeping my eye out for a good pressing method but still nothing has come up
which sucks because i have 34 acres that is prime for some algae ponds

i agree that algae diesel is worth researching and investing in for the fucher

hey 4wheeler.....after extracting the oil, what happens to the algae? is it basically just dead biomass that helps feed the rest of the crop or what? also what type of solvents are we talking about? i can get the algae and the solvents and the lab from the college to run these experiments..

wow 34 acres...thats a lot of algea.......i have a couple small 20ftx20ft agricultural ponds that are spring and run-off fed...is there an ideal ratio of algea mass/oil volume that you know of?

the remainder algae cells after extraction end up as mulch ( could be used to burn) there is some ideas out that to take it and ferment it and git ethanol from it but i haven't read to much in to it

the most popular solvent is Hexane (SP?) throw you algae in it and you basically distill the solvent off and the remander is the oil and algae cells separate and you have your oil

the 34 acres is the remainders of the familys avacoto ranch

yes if the tress were still alive and producing fruit i would be harvesting them for the oil ;)

There is another group that had developed a bacteria that is producing biod. now too.

http://technology.newscientist.com/article/dn10116-gm-bacteria-churn-out-microdiesel-fuel.html

kind of an older article. Saw on either Discovery or Science Channel that there is a company in the Western US that is doing this. They are saying that the bacteria are putting out a biodiesel that is pure enough to use with little or no additives or refining. They can use pretty much any bio mass to feed the little buggers too. Might be a good use for the seaweed.
