ScribeMedia.Org: The Business, Technology and Culture of Digital Media | Initial Test Results Indicate at Least 33,000 gallons of Algae Oil per Acre Possible

This is extremely optimistic, and it will be interesting to see if they are really able to scale this operation with similar productivity. Note to self: Get some more recent information about this company.

If proof is in the pudding, Valcent’s pudding is looking mighty green to me.

Not too long ago, I spoke (video) with Valcent Products Inc. CEO and Principal Scientist Glen Kertz about his company’s Vertigro bioreactor system.

Judging from the first wave of Vertigro test data, the promise of sustainably producing large amounts of biofuels-ready algae oil is becoming more and more of a reality — and a potentially revolutionary reality at that!

From the Valcent/Vorticom press release:

During a 90 day continual production test, algae was being harvested at an average of one gram (dry weight) per liter. This equates to algae bio mass production of 276 tons of algae per acre per year. Achieving the same biomass production rate with an algal species having 50% lipids (oil) content would therefore deliver approximately 33,000 gallons of algae oil per acre per year.

…As a comparative, food crop such as soy bean will typically produce some 48 gallons oil per acre per year and palm will produce approximately 630 gallons oil per acre per year. In addition, the Vertigro Bio Reactor System is a closed loop continuous production system that uses little water and may be built on non arable lands.

The press release goes on to note that the focus of the 90 day test was determining the robustness of the test bed — not pushing the limits on production yields. The official line from Valcent stresses that the test system has not been optimized for maximum yields or the best selection of algae at this time.

Powering Our Automotive Future with–Pond Scum: Scientific American

Costs for algae-based fuel currently range from $10 to $100 per gallon, according to systems engineer Ron Pate at Sandia National Laboratories. “The idea [is] bringing algal oil down to $1 or $2 per gallon at a scale of 50 million gallons [190 million liters] per year.”

High cost is a problem throughout the algal biofuels industry. “It’s energy cost to pump the water,” says Craig Harting, chief operating officer for Vancouver-based Global Green Solutions, which is building 100 bioreactors (large plastic devices used to grow algae) at a pilot plant in El Paso, Tex. “It’s capital cost to build bioreactors. It’s the harvesting and extraction process.”

As a result, most companies say they have yet to determine the consumer price tag for algae-derived oil—or to produce much of the stuff—though Wolfson says Solazyme’s goal is $40 to $80 a barrel—competitive with fossil oil.

Investors doubt algae energy “is going to come down the cost curve”

September 25th, 2009

Jim Matheson, a general partner at Flagship Ventures, said “we just don’t believe the economics.” Although the venture capital firm invests heavily in bio-energy technology, “we just haven’t gotten very comfortable that algae is going to come down the cost curve.”

BP also doesn’t like photosynthetic algae. “We don’t think that [technology] will ever reach the kind of cost or supply that we think people are prepared to pay,” said David Eyton, the head of research and technology at BP. His statement was a direct challenge to a main BP competitor, Exxon-Mobil, which recently announced an investment of $600 million in photosynthetic algae.
