Greentech Media: Growing Algae: Open Pond vs. Closed Bioreactors | Green Light

Good article describing the key players in the industry.

NREL’s Aquatic Species Program concluded that open ponds are the optimal economic design and used open ponds for its experiments and economic models.Algae can be grown in natural or man-made ponds. The advantage is cost: open pond growth requires less capital equipment than other techniques. The disadvantage comes in quality control. Raceway ponds, shaped like horse tracks, for growing algae for human consumption are not yet economical for fuel production while nutraceutical algae can sell for several thousand dollars a ton.Raceway ponds, usually lined with plastic or cement, are about 20 to 35 cm deep to ensure adequate exposure to sunlight. Paddlewheels provide motive force and keep the algae suspended in the water. The ponds are supplied with water and nutrients, and mature algae are continuously removed at one end.NREL’s Aquatic Species Program concluded that open ponds are the optimal economic design and used open ponds for its experiments and economic models. The productivity of raceways is much higher than unmixed algae ponds.

Israelis at the forefront of the green industry | Jerusalem Post

November 1st, 2009 No comments »

On the algae conference in Bangkok this year I met two Israeli scientists with deep knowledge and experience from algae research. No doubt – I think they are among the absolute top-league thought leaders globally. The issue I have with this article, however, is that the Israeli researchers I spoke with were very reluctant to the hype and over-optimistic projections made by industry participants.

TODAY, TEAMS of Israeli cleantech scientists and engineers are inventing the tools necessary to make deserts bloom with energy crops while mitigating the worst of the electric power industry’s greenhouse gas emissions. They are combining their cutting-edge knowledge of biochemistry, water management, desert agriculture and solar power to create this new industry.

We believe that algae farming in the US holds the promise of recycling one-fifth of its electric power industry’s greenhouse gas emissions, slashing its need for imported oil by 2 million barrels a day, and spinning off significant quantities of sustainable feed for growing fish and livestock to support the caloric needs of the world’s 6.5 billion people.

And the opportunities are even greater in China.

Algae is one of the world’s fastest-growing plants, and can thrive without fresh water or fertile land. Unlike many other biofuel feedstocks, it would avoid conflict with food production and rain forest conservation. And, of course, algae eat CO2 in vast quantities.

Solar energy turns two tons of CO2 into one ton of algae. And the industry is learning to stand on its own two feet.

As President Obama spoke at the UN, the experimental vehicle Algaeus rolled into New York City. The Algaeus’s 10-day inaugural trek showcased the ability to use today’s automotive technology – hybrid engines and algae-derived energy – to cross North America on 25 gallons of fuel, getting 148 miles per gallon.

The trip served as the capstone to the “Summer of Algae,” when energy giants Exxon Mobil, Pinnacle West and Dow Chemical each teamed up with corporate, university and government scientists to announce the launch of nearly a billion dollars’ worth of algae farming projects. None of this would have been possible without the toolkit developed by Israeli scientists and entrepreneurs.

RWE plans to generate electricity from algal diesel – Biodiesel Magazine

November 1st, 2009 No comments »

Providing “estimated yield” figures – hey, RWE: Keep us posted when you have real figures!

Armstrong and Tompkins applied their experience in automation and process control to develop what they believe will be a cost-effective photo-bioreactor. Armstrong said their projections show a 12.8 percent return on investment for a 1.6 megawatt (MW) unit, while a larger 5 MW system should provide a return on investment closer to 15 percent. An individual photo-bioreactor panel measures 4 feet wide by 6 feet high by 3 inches thick, with 550 panels contained in one cell and five to six cells covering an acre of land. The process utilizes automated harvesting, reducing the moisture content in a prescreening process to about 20 percent, before being pumped to a final screen and dried further if necessary prior to processing. The estimated yield per acre is between 95 and 125 tons of dried biomass per year, according to Armstrong.

Another over-optimistic article? No details provided but worth checking what the company has to show…

GEORGETOWN, SC (October 22, 2009) – The future of algae energy has come, today. Renewed World Energies, a pioneer in algae-for-biofuel technology, unveiled an operational prototype of its photo-bioreactor at the Algae Biomass Summit in San Diego, CA. The energy company has achieved the technology breakthrough that will forever transform the dream of algae energy into a reality; making algae green the new black gold.

Renewed World Energies has cracked the algae energy code; a feat that competitors have projected is five to ten years away. The Large Scale Photo-Bioreactor System is the first commercially viable, fully automated, closed system microalgae production technology in the world today. The groundbreaking process developed by co-founders Richard Armstrong and Tim Tompkins, grows algae under operator selected conditions and uses existing technology to harvest and extract algae oil from microalgae.

NCBH Prize announced for commercial fuel from algae: $10 million incentive modeled after X-Prize for private space flight.

October 31st, 2009 No comments »

SAN DIEGO, Oct 09, 2009 (North County Times – McClatchy-Tribune Information Services via COMTEX) — NCBH | Quote | Chart | News | PowerRating — Just as the Ansari X Prize jump-started private space flight, a North County venture capital firm has started a competition to produce commercially viable fuel from algae.

The Algae Fuel Prize, offered by Del Mar-based Prize Capital, was announced at this week’s Algae Biomass Summit, a meeting in San Diego of experts in using algae for fuel, food, purifying water and other purposes.

The goal is to offer $10 million, the same amount as the Ansari X Prize, said Lee Stein, Prize Capital’s founder.

Stein said the actual amount may change, because the rules and guidelines for the prize aren’t final. But the main goal is fixed, he said, which is to add a new source of fuel and not to compete with food crops, as with ethanol made from corn.

“We want to work with third-generation biofuels: Land that cannot be used for food,” Stein said. “That was our primary concern.”

* Commercial biofuel from algae still 7 to 10 years off

* Companies look to gene-based methods for perfect strain

* Others focus on system design to grow algae

By Laura Isensee

SAN DIEGO, Oct 8 (Reuters) – Filling your vehicle’s tank with fuel made from algae is still as much as a decade away, as the emerging industry faces a series of hurdles to find an economical way to make the biofuel commercially.

Estimates on a timeline for a commercial product, and profits, vary from two to 10 years or more.

USATODAY.com – Algae like a breath mint for smokestacks

October 31st, 2009 No comments »

Article from 2006. Will be interesting to see what has happened to the companies mentioned – and why….

Overshadowed by a multibillion-dollar push into other “clean-coal” technologies, a handful of tiny companies are racing to create an even cleaner, greener process using the same slimy stuff that thrives in the world’s oceans.Enter Dr. Berzin, a rocket scientist at Massachusetts Institute of Technology. About three years ago, while working on an experiment for growing algae on the International Space Station, he came up with the idea for using it to clean up power-plant exhaust.

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.
