Will Micro-Algae Become a Disruptive Technology?

Just as corn and peanuts stunned the world decades ago with their then-newly discovered multi-beneficial uses and applications, Texas AgriLife Research scientists in Corpus Christi think microalgae holds even more promise.

...There are an estimated 200,000 to 800,000 species of microalgae, microscopic algae that thrive in freshwater and marine systems, Fernandez said.


Of all those species, only 35,000 species have been described, he said. _SD

Carlos Fernandez Texas AgriLife Research LabMicro-algae can be prolific sources of biomass and lipids -- both of which are prime feedstocks for biofuels production. But algae are already grown and used profitably for a wide range of commercial products(Wikipedia). The research described below involves both basic and applied research for micro-algae.

"We're only starting to scratch the surface of discovering the natural secrets of microalgae and their many potential uses and benefits," he said. "But already it's obvious that farmers will one day soon be growing microalgae on marginal land that won't compete with fertile farmland. They won't even compete for fresh water to grow."

To understand how best to grow it, Fernandez constructed a microalgae physiology laboratory to study how it's affected by temperature, salinity, nutrients, light levels and carbon dioxide.

"We have four bioreactors in which we grow microalgae to determine the basic physiological responses that affect its growth," he said. "We will then integrate these responses into a simulator model, a tool we can use in the management of larger, outdoor systems."

In this study, different strains of microalgae will be evaluated for their capacity to produce large amounts of lipids, or fats, that can then be converted to produce and refine diesel and other biofuels, Fernandez said.

"Along with that, after extracting the lipids from the biomass of microalgae, there is a residue that we are going to analyze for its quality for use as feed for animals, including fish, shrimp or cattle."

Eventually, studies will evaluate the possibility of using the residue as a soil fertilizer.

"There are lots of other potential uses for the residue, but for now our focus is on feed and fertilizer," he said. _SD

If algae are grown in bioreactors, they will likely be oriented vertically -- which will act as an "area multiplier." In other words, far more algae can be grown "per acre" using vertical bioreactors than using horizontal ponds and raceways. The challenge for bioreactors involves using cheap materials which are durable and efficient.

Ponds and raceways can be built on non-productive lands, using brackish, salt, or waste water -- so as not to interfere with either food supplies or potable water supplies. In fact, algae can even purify wastewater to make it drinkable.

Algae can be prolific producers of fuels, foods (for humans), feeds (for animals), fertiliser for soils, cosmetics, chemical feedstocks, nutrient supplements, and many more products and precursors only now being discovered.

It is true that at this point in time, micro-algae cannot produce a biofuel which is price competitive with petro-fuels. But it would be wrong to make future predictions based upon current technologies. Companies which find early profitable niche uses for micro-algae are apt to expand into ever newer, larger, more recently profitable niches over time.

A list of international companies attempting to produce fuels from algae (Wikipedia). The list is not complete by any means.

The world is not what you think it is, because the world is constantly changing -- mostly out of your line of sight. The organisations and persons responsible for keeping you informed about the state of the changing world are generally incompetent boobs, crooks, and cronies -- tunnel-vision locked onto their own agendas and corrupt commitments. You are nothing but pawns on the board to these people: your professors, your government officials, your talking head anchors and pseudo-intellectual journalists and pundits.

Yes, micro-algae can become a disruptive technology, once the infrastructure of growth, production, distribution, and end-use is built.

But the most disruptive "technology" of all is the independent human mind that is ambitious, ever-searching, and willing to work opportunistically toward high-value goals as they come into view.

Algae are Optimistic about the Future

Abstract from study

NewScientist
While human academics and analysts are all too quick to write off algae as serious contenders in the energy race, the algae themselves are completely optimistic about their own futures. Perhaps the algae know something that we do not know? Well, for one thing, algae is already a big business. For another, algae has a lot of potential for productive yield -- and is just getting started.

ALGAE are being put to work performing a unique double duty: cleaning up sewage waste while simultaneously producing biofuel.

All algae feast on phosphates and nitrogen-containing compounds, converting them to lipids. Some of these oils can be converted to biofuel, but only a few algal species produce lipids of the right type and quantity to be easily converted to fuel. In theory, though, algae are a perfect renewable fuel source. The main obstacle is that brewing the right nutrient mix can be prohibitively expensive.

Now, in work for a master's thesis, Eric Lannan, a mechanical engineer at Rochester Institute of Technology (RIT) in New York and colleagues have identified three types of microalgae - Scenedesmus, Chlorella and Chlamydomonas - that efficiently convert nutrients to fuel on a diet of municipal waste water, while happily living in its harsh, salty environment. In a lab test, it took just three days for the algae to gobble up 99 per cent of the ammonia, 88 per cent of the nitrate and 99 per cent of the phosphates in a broth resembling that from a domestic sewage treatment plant, turning themselves into rich sources of fuel even as they purified the water.

"People had looked at algae to clean waste water, others to make biodiesel," Lannan says. "We're putting those ideas together." _NewScientist

The idea to use waste feedstocks for boosting algal production is not especially new, but it still needs to be demonstrated on a large scale. And the demonstration must show that the resulting algae can be used to produce valuable products to make the entire process self-sustaining and profitable.

Besides using wastewater, the use of high CO2 effluent from power plants and cement factories etc. would provide the carbon boost for rapid growth, which algae crave.

Algae do not need too much sunlight -- in fact too much sunlight can reduce yields for valuable algal products. Solazyme, for example, grows its algae in the dark by feeding them sugars from biomass for fuel. They claim an 80% lipid yield, which is quite high.

Artificially inflated prices for crude oil are driving a multitude of approaches to the production of alternative liquid fuels. Fuel from algae is but one of many alternative approaches to liquid fuels, and algal researchers are taking dozens of divergent approaches to create algal fuels. Other microbial fuels approaches appear equally promising at this time.

A lot of money is going into the effort to create microbial fuels and fuels from biomass. But the key discoveries will not necessarily come from the best-financed research labs. Time will tell.

Those who think "biofuel" means only maize ethanol, are going to be very surprised when they discover what is really happening.

Some Product Claims Go Beyond Whimsical

GreenTechMedia
Some of algal biofuels company BARD's claims are too whimsical to put in a headline or title. But in an atmosphere of mainstream doubt regarding the short to intermediate-term viability of algal fuels, these claims are too cute to ignore. Keep in mind these claims are for yields, not for profitability:

"Biofuel Advance Research and Development, LLC (BARD) has entered into an agreement with The Green Institute Inc. to construct and operate a commercial scale algae system pilot facility located in the Commonwealth of Pennsylvania. The planned facility will produce algae biomass to be used to produce biodiesel, and other commercial products. The pilot facility is estimated to produce 20,000,000 gallons of algae oil / biodiesel per acre per annum (!) [emphasis added]. Initially, the pilot facility will produce 43,070 gallons of algae oil / biodiesel per annum using 6 modules of photo-bioreactors covering 84 square feet." _Greentechmedia

Got that? The claim is for roughly 43,000 gallons of oil from 84 square feet over one year. Since there are roughly 43,000 square feet in an acre, they claim that they would have produced over 20,000,000 gallons of oil per year had they expanded their lab facility to 1 acre size.

Here is what an algae guru from NASA and other algae experts say about the claims:

According to John Benemann [an algae expert], with 'normal' systems we can expect at the very most 5,000 gal/acre/yr from open ponds. This either means that BARD is doing something very revolutionary or they are not telling us that their yield of 9+ million gal/acre will take them 1,886 years to produce! We have a real problem with light unless of course we use artificial light and then we have an energy problem or a photonic materials cost problem... These guys may have discovered a miracle organism, but I suspect they are selling snake oil rather than making algae oil.

...According to Bob Walsh, the CEO of Aurora Biofuels: "While it is hard to comment on another company's technology when you are not under the hood, I can say we believe the absolute theoretical maximum is 10,000 gal/acre/year. The white paper GreenFuel Technologies: A Case Study for Industrial Photosynthetic Energy Capture by Dr. Krassen Dimitrov, PhD, March 2007 goes through the calculations.

"We also believe engineering systems [photo bioreactors and their ilk] will not deliver huge increases in productivity. Engineering has to drive out the typical costs of algae production but cannot double production. Our most recent scientific progress, which decreased photo inhibition increased our capability from the 2,000 gal/acre/year level to consistently producing above 4,000 gal/acre/year. Our scientific team believes 6,000 gal/acre/year is an achievable target." _GTM

Clearly BARD is doing a great deal of extrapolation, and is likely supplementing its module's sunlight with artificial light, in addition to feeding its algae some very expensive algal food. Yield is irrelevant if the process is not economically viable.

But there are ways to fudge the yield. Imagine a tall rotating cylindrical building, with a 120 ft radius and a height of 4,000 feet. The algae are grown on panels (or bags, etc) on the cylinder's outer surface. Given an oil yield of 5,000 gal / acre / year on the cylinder's surface -- but with the building's footprint occupying roughly 1 acre of land -- an algal facility could theoretically produce about 20,000,000 gallons of oil per "acre" per year, using only sunlight for photons.

Perhaps this is what BARD has in mind? They will have to find a cheap way of rotating the building to provide uniform sunlight for all the pannels. Of course their are other ways of sharing the sunlight -- rotate only the outer surface, or slide the panels around in any number of elaborate patterns . . . Or if BARD locates the building on a hill surrounded with mirrors that bathed the panels with sunlight, they might get away with a smaller building. You can probably think of a novel approach yourself if you give it some thought. But keep it between yourself and your investors, for now.

It all depends upon what BARD's investors or government sponsors are willing to go for. The numbers provided are certainly impressive -- large enough to throw your blog host into a whimsical mood at the very least. So whimsical that I hesitate to pour that scotch and water, savouring the natural whimsy instead.

Discovering Our Abysmal Ignorance of Life in the Sea

MontereyBayAquariumResearchInst
An entirely new species of "algae" has been discovered living in both saltwater and freshwater environments. The discovery may be much larger than the researchers dared to dream -- and reveals a deep human ignorance of what is actually happening in the world's oceans.

A team of biologists has discovered an entirely new group of algae living in a wide variety of marine and freshwater environments. This group of algae, which the researchers dubbed "rappemonads," have DNA that is distinctly different from that of other known algae. In fact, humans and mushrooms are more closely related to each other than rappemonads are to some other common algae (such as green algae). Based on their DNA analysis, the researchers believe that they have discovered not just a new species or genus, but a potentially large and novel group of microorganisms.

...When asked why these apparently widespread algae had not been detected sooner, Sudek speculates that it may in part be due to their size. “They are too small to be noticed by people who study bigger algae such as diatoms, yet they may be filtered out by researchers who study the really small algae, known as picoplankton.”

Sudek says, “The rappemonads are just one of many microbes that we know nothing about—this makes it an exciting field in which to work.” _MBARI

Humans are not even close to getting an accurate species count for either land or sea.

Human science is ignorant about a lot of things in the natural world. It is safe to say that there are more things that science does not know about the world, than things it does know. Science is ignorant, for example, of how microbes are able to survive in so many extreme environments. Science understands very little so far about genetics and epigenetics. Science does not even understand why plants are shifting their areas of growth downhill, when IPCC climate scientists have been declaring categorically that a warming Earth would force plants to retreat uphill.

We are living in a much stranger and more wonderful world than science so far can understand. How much better it would be for us to separate science from politics, so that we could understand these mysteries more clearly.

Peak Oil: Meet 10,000 Gal/Acre Algal Diesel Made at $1.25/gal

Cost of the firm’s [Photon8] algal based diesel fuel is said to be $1.25/gal which permits retail pricing at or below petroleum diesel without subsidies.

Photon8 has demonstrated photobioreactor production rate equal to 1.5 gal/square meter/yr and is on its way to an expected rate of 22,000 gal per 2.5 acre/yr then to best economic units of 5 acres. It believes further development may bring it close to 10,000 gal/acre/yr as a basis for planning large production systems, according to Brad Bartilson, President & CEO, Photon, Inc, Brownsville, TX. _Ai-Online_via_BiofuelsDigest

Photon8 is a new Texas algal fuels startup, based on technology developed at UT Brownsville. The company utilises "genetically enhanced" algae, and intends to produce a "drop-in" diesel fuel which requires no blending with petro-diesel. Photon 8 claims a number of unique technologies with patents pending.

Brad Bartilson is the president and CEO of Photon8 and seems to at least talk a very good game.

Brad Bartilson, Photon8’s president and CEO, says the Traveling Wave Tube technology boosts algae growth by 500 percent, representing a major advance in the profitable conversion of algae to biofuel — "profitable" being the key word...

...He invented his own patent-pending "photo-bio reactor" in order to slash production costs. Now, Traveling Wave Tube promises to cut costs further by dispensing with limits normally imposed on algae-to-biofuel production during "degassing" and the addition of carbon to the algae. In a nutshell, algae "broth" is exposed to sunlight in order to produce oily "lipids" — the more the better. The lipids are harvested for biodiesel production.

...Photon8 has discovered how to coax more lipids out of individual algae cells through genetic manipulation...Photon8’s team has figured out a short cut, Bartilson says.

"If you’re in production what you care about is how much oil (the cells) produce a day." he says. "Now we have confirmation that these cells are producing lipids at twice the rate of a wild cell."

Despite the breakthroughs, Bartilson finds himself struggling against a perception in the algae-biofuel industry that some problems are insurmountable — including the ones Photon8 claims to have surmounted.

"It’s so frustrating for me," he says. "I feel like were fighting town hall to some extent. Those that came out first are now being looked at as the ‘forefathers.’ The mantra from these folks is nobody has solved the confounding issues — (they say) we don’t have algae that can produce at the rate we need, and second there is no growth system that can have profitability. We have those, so we have to make believers." _BrownsvilleHerald

One of the UTB professors who has been involved in the underlying academic research is Tamara Pease. Dr. Pease appears to have an eye on some critical issues involved in the production of photosynthetic organisms to fuels -- both on an immediate time scale and on a geologic time scale.

Something tells me that Dr. Pease would be reluctant to make the same claims about Photon8's "mutant algae" that Mr. Bartilson is making. It is much easier to talk about breakthroughs and "10,000 gallons an acre production" than it is to actually produce an algal based diesel-equivalent that is cost-competitive with petro-diesel.

All the same, if Photon8 can bring their fuel to market within the next 10 years, Al Fin energy analysts will be quite impressed.

More algal energy news: OriginOil is focusing more narrowly on its algae extraction process -- moving toward a continuous separation process called "Live Extraction" which preserves the viability of the algae cells after "milking", for further lipids production.
OriginOil is a a better established company than Photon8, but in a wide-open field such as algal fuels -- still in its infancy -- it is far too early to predict ultimate winners and losers.
