Baylor Professor Turning Cow Manure into Fuel-grade Ethanol
You are at: Oilgae Blog.
The project will be designed to turn the manure from the dairy’s 400 cows into pure ethanol that can be blended with gasoline as fuel. Unlike conventional ethanol, it would require no fossil fuels to produce. The distillery would run on methane from a manure digester.
The byproduct of the distillations would include concentrated nitrogen and phosphorus fertilizer, which could be packaged and sold. And carbon dioxide emissions from the process might even be used to grow algae that could be turned into biofuel.
But the main purpose is to develop systems that dairy farmers can buy to turn their herds’ waste into a profitable commodity instead of allowing it to pollute streams, Lehr said.

Biofields turns Algae to Ethanol
You are at: Oilgae Blog.BioFields will produce biofuel from algae on an industrial scale as of 2014 in a plant located in Puerto Libertad, Sonara state.
This large-scale pilot programme will be set up 300 km from the United States, which will be their main client.
According to Sergio Ramirez, director of Corporative Affairs of the company, the plant should be finalised in the second half of 2010.
BioFields owns the rights to use the technology “Direct to Ethanol” in Mexico, developed by the firm Algenol, which permits biofuel production from hybrid green-bluish seaweed, Ramirez explained.
Algae produces ethanol naturally, and the technique applied optimises the process so that it is direct and on an industrial scale.

Garden State Ethanol Plans for Algae to Ethanol Biofuel Plant
You are at: Oilgae Blog.
New Jersey-based Garden State Ethanol has selected a landfill site in Woodbine, Philadelphia, for the location of a $200 million (€142 million) biofuel plant that would use more than 100 bioreactor tanks to convert algae into ethanol and biodiesel oil.
Garden State Ethanol is currently seeking funds for the project. If approved, work on the plant may begin as early as next year.

Algenol Works With Mexican Government for Algae Ethanol Commercialization
You are at: Oilgae Blog.To see the face of the future of alga ethanol, one would only need to look toward Algenol, the sole company that has discovered how to make the alternative fuel. Although macro-algae (seaweed) has been fermented for hundreds of year, Algenol has invented a method of fermenting micro-algae, something no one else has discovered and making them true innovators in their field. Through an agreement with Biofields, Algenol has been working towards producing this viable fuel for the past fifteen years, and has found a way using a non-toxic, abundant algae and salt water -- something producers of biodiesel cannot do.
Grown within bioreactors, Algenol uses the blue green algae--better known to the science world as cyanobacteria--saltwater, sunlight, and essentially yeast to "bubble [ethanol] out of the air. It's a natural distilling process."
"We look for two things: [an alga's] ability to produce energy and to ensure that they aren't toxic," explained Smith for Algenol's move to use cyanobacteria. "We modify the algae to produce ethanol where it traditionally produces biodiesel."
"We have a billion gallon facilities in four stages. It's taken fifteen plus years, and the ultimate goal is to get this extremely independent of the niche market," said Smith. "We are anticipating production by the end of this year. [Our algae ethanol] will be commercial this year, and [we will] hopefully acquire land in [the U.S. in] 2009 and early 2010."

Advantages of Heterotropic Algae for Biofuels
You are at: Oilgae Blog.The following was a comment provided at one of the blog posts on ethanol I read recently. While I'm no expert on the heterotrophic processes, the arguments here really sound interesting;
"
The Advantages of Heterotrophic Algae Grown at Corn Ethanol Refineries
Solazyme and Solix use two distinctly different methods to produce algae. Solix grows photo-autotrophic algae in the light. Solazyme grows heterotrophic algae in the dark.
Heterotrophic algae does not require sunlight, but the tradeoff is you have to feed it some kind of sugar. Initially, that sounds inefficient. Why expend the cost of sugar, when you can grow algae in sunlight for free. Look a little deeper, and here are the advantages of growing heterotrophic algae in the dark: (1) By growing algae in the dark, the process is simplified. Otherwise, you have to get the algae exposed to the light, or get the light to the algae. That takes up solar surface area, which translates into large land masses. (2) Because the algae can be grown in the dark in tanks, it can be grown anywhere, with a minimum footprint. (3) Heterotrophic algae, grown in nutrient rich water, becomes many times more concentrated, at a hyper fast growth rate.
HETEROTROPHIC algae grows in the dark, and multiplies rapidly when fed sugars or local biomass cellulose converted to sugars. Beside Solazyme, this technology is also being developed by East Kentucky University and General Atomics, working together. They are leveraging local biomass sugars by feeding it to heterotrophic algae grown in vats. Researchers claim that heterotrophic algae can reach densities in the dark that are 1,000 times higher than strains of photo-autotrophic algae that must be grown in the light.
Heterotrophic algae can be grown in the dark in tanks, using very little land. Tanks can be stacked a hundred feet underground, or stack them a hundred feet high above ground. Stack them in a high rise. Grow it in gray water in your basement, on your roof, under your backyard, or under a parking lot, using no additional land. Grow it on a barge.
Take local sugars derived from biomass, corn or sweet sorghum, or food and paper waste, or sewage, or what have you. And leverage the sugars to multiply the algae many times. That is going to be your massive source of feedstock for ethanol, biodiesel, feed, fertilizer, or for whatever you want to make.
Corn ethanol refineries have readily available waste heat, CO2 waste, nutrient rich waste water effluent, and corn sugars. This is a perfect match for growing heterotrophic algae. Why take corn sugar and feed it to algae? Because you multiply the feedstock many times in a short period of time, onsite. It’s conceivable that you could combine a tablespoon full of live algae with a pound of corn sugar, and bubble CO2 waste through a medium of nutrient rich waste water effluent, keep it warm with waste heat, and get a return of 20 pounds of algae or more within 48 hours.
Take all the corn sugar that is now going straight to 10 billion gallons ethanol, and instead, feed it to heterotrophic algae in tanks. At only 20X, that would yield upwards of 200 billion gallons of ethanol per year in the U. S. alone.
Out of tens of thousands of strains of algae, thirty two types of heterotrophic algae have been identified thus far. Some are high in starch. Some are high in oil. Some are high in proteins. Depending on what you want to produce, you would select your strain accordingly. And after your primary product has been taken from the feedstock, you would also make value added products from the remaining materials. Grow a high starch variety of algae ideal for ethanol production. Grow a variety of algae ideal for oil production, or high protein feed production, or fertilizer production. Since corn ethanol plants already produce distillers grains and supply the livestock industry, they would now have a second high protein feed product to market alongside.
We now have 172 corn ethanol refineries, which form a viable framework for a much bigger biofuel and feed industry yet to come.
"
Well, I guess I have one big question for those who think heterotrophic growth method is great. Whatever be the X (10X, 20X) whatever, if the algae are growing to derive most of their energy from sugar (non-photosynthetic sources), you will need almost as much sugar or more as the energy generated ultimately from ethanol (if the only energy sources are sugar, nutrients, CO2 and some warmth). The following sentence sounds too good to be true: "It’s conceivable that you could combine a tablespoon full of live algae with a pound of corn sugar, and bubble CO2 waste through a medium of nutrient rich waste water effluent, keep it warm with waste heat, and get a return of 20 pounds of algae or more within 48 hours." How does it produce 20X mass from just less than 2X of sugar + initial amount algae? Are the rest 18+ pounds derived from CO2 and nutrients? In that case, we are going to need a lot of nutrients and CO2, and both have costs attached.
I need to dig deeper into the economics of heterotrophic growth, but the comment has surely tickled my interest. I doubt the numbers are as good as those presented at the comments, but let me first do more research on this.

Ethanol from Blue-Green Algae - via Acetobacter xylinum genes
You are at: Oilgae Blog.Numerous alternative means of manufacturing ethanol have cropped up recently, such as this method devised by scientists from The University of Texas at Austin. This new method entails the use of a microbe, more particularly a photosynthetic cyanobacterium which is more popularly known as blue-green algae. This cyanobacterium can produce cellulose which could be turned into ethanol, as well as sucrose and glucose which could directly be converted to ethanol too. The cyanobacteria are able to produce cellulose through the implanted genes from vinegar bacterium, Acetobacter xylinum, which is a non-photosynthetic cellulose producer.

Algae Biodiesel vs. Cellulosic Ethanol - an interesting comparison
You are at: Oilgae Blog.Here are some comparisons:
(1) Algae can be converted into ethanol or diesel, depending on the process.
(2) Cellulose feedstock, generally speaking, has a much larger geographic footprint than proposed algae designs.
(3) Both algae and ethanol can be grown utilizing waste streams.
(4) Cellulosic feedstock for ethanol is available now. Algae feedstock is not clearly ready.
(5) For both of these very promising feedstocks, algae and cellulose, we are going to wait a few more years before we’ll hopefully get a clear indication as to whether or not they truly emerge as major sources of transportation fuel.
This report does not consider converting algae to ethanol, from what I understand but rather does a direct comparison between different feedstocks for ethanol and for biodiesel (algae). However, it is an interesting article.

Algenol hires Schlicht, Denman; to build Mexico facility
You are at: Oilgae Blog.Florida-based Algenol Biofuels Inc. announced Sept. 15 the appointment of two new employees. Greg Schlicht has been named senior vice president of business development and general counsel, while Dax Denman will serve as senior program manger.
Founded in 2006, Algenol has developed a technology using algae to produce ethanol. The technology, trademarked as Direct to Ethanol, produces industrial-scale low cost ethanol using algae, sunlight, carbon dioxide and seawater. Each algae cell used in the process is like a tiny ethanol factory. Sugar is produced through photosynthesis and immediately converted into ethanol. The algae grow in 500 gallon sealed containers. Ethanol produced by the algae evaporates into the head space of the container and is then collected and purified.

Algenol Enters The Algae Biofuel Race With Process Economics Advantage
You are at: Oilgae Blog.The USA-based firm Algenol has struck a deal with Mexico-based BioFields to grow and process algae in a manner that cost effectively produces ethanol - directly from the culture. This is quite different from the usual algal biofuel processes that use algae to produce biological oil which, after extraction from the algal cells, is used as feedstock for liquid fuel production: often biodiesel. If, as claimed by Algenol, ethanol can be extracted directly from the algal culture media, we suppose that the process may be drastically less capital and energy intensive than competitive algal biofuel processes. No need to pull out biomass, squeeze it dry on a belt press, and extract the oils in still a third processing step.
"Algenol plans to make 100 million gallons of ethanol, about the average annual capacity of one traditional US distillery, in Mexico's Sonoran Desert by the end of the 2009. By the end of 2012, it plans to increase that to 1 billion gallons -- more than 10 percent of current ethanol capacity in the United States, the world's top ethanol producer."

BOSTON - State leaders are preparing to announce a major effort to lure biofuel companies, focusing on incentives for the production of non-corn-based ethanol.
Expected to be announced soon, the proposal seeks to encourage biofuel investment by stimulating demand. Officials are hoping the plan can reap environmental benefits while nurturing an industry that capitalizes on in-state natural resources.
Gov. Deval Patrick said last week that the plan will pursue cellulosic ethanol, a non-corn-based biofuel, using resources the state can rely on, including cranberries, algae and switchgrass.

Don't Bet on Corn for Energy Independence

May 09, 2007
This interesting article from Concord Monitor says why the world should say no to corn-based ethanol, and should instead look at ethanol from feedstock such as switchgrass, algae and cellulose.
Listen to some of the very-credible arguments.
One-fifth of America's corn crop is now fed not to people or livestock but to the ethanol factories springing up all over the Midwest.
Corn production is at a 63-year high, but prices keep rising. That's driving up the cost of meat, poultry and most other supermarket items. But those are the little problems with corn-based ethanol...there are much bigger problems.
America's bumper corn crop has been a big factor in feeding the world's poor. So have American surpluses in wheat and other grains. More corn for ethanol means more expensive grain for the poor, and is causing many other economic turbulences around the world.
Corn requires lots of nitrogen-heavy fertilizer. Corn needs a lot of water. So do the plants that turn it into ethanol - a half-million gallons per day or more. The water table is dropping in some ethanol-producing regions, and erosion and fertilizer runoff are increasing...
If every bit of corn now grown in the United States were converted to ethanol, it would meet only 12 percent of the nation's fuel needs for transportation alone...
Conclusion? Ethanol will have to be made not from crops like corn, or even soybeans or sugar cane, which reduce C02 emissions even more compared to oil. To be an alternative, ethanol will have to come from waste wood, weeds like switch-grass or perhaps even pond algae.
You would agree with the conclusion, wouldn't you?

Land of algae, milk and biofuel!
You are at: Oilgae Blog. See the complete list of Oilgae Blog articles.Land of algae, milk and biofuel!
Ed Taylor, Tribune, May 13, 2007
Milk and biofuel is an odd combination, but a Phoenix, Arizona-based company is planning to produce both. When fully built, the ag-industrial complex planned by the XL Dairy Group will produce 100 million gallons of ethanol, 25 million to 30 million gallons of biodiesel fuel and 21 million gallons of milk a year.
The concept is to use waste produced by the dairy cows to make energy that would be used to turn corn into ethanol and biodiesel, said Dennis Corderman, chief executive and chairman of XL Dairy Group. Byproducts of the ethanol and biodiesel production will be cycled back to produce energy for the biorefinery and to provide feed for the dairy cows.
The difference between this project and other ethanol plants is that this project will use waste streams from the dairy to produce its own energy - to provide the electrical and heat and steam energy for the entire facility. The operation will have an energy efficiency ratio of 10-to-1, where conventional ethanol plants have an energy efficiency ratio of about 1.2-to-1, he said.
So where does algae play a role in the scheme of things?
After the second phase goes into action, instead of corn, the company will use algae as the feedstock to produce both ethanol and biodiesel. XL plans to grow algae on 2,400 acres of adjacent state land, using manure water, carbon dioxide produced as a byproduct of the ethanol process and sunlight.
The company will propagate algae in a patent-pending system of horizontally mounted clear tubes.

Bio-diesel: Engineered algae the way to go
News from Malaysia, KA Cheah, Feb 5, 07
Excerpts:
1. There are plans for Tenaga Nasional Berhad (TNB) and all the independent power producers (IPPs) in Malaysia to grow engineered algae as feedstock in bio-reactors at their power stations to produce bio-diesel and also bio-ethanol.
2. The tapping of engineered algae to produce bio-diesel and bio-ethanol has the best potential of great success because algae is very oily (it has about a 50% oil composition), it is the fastest growing organism and it becomes very dense enough to be harvested three times a day.
3. The absorption of carbon dioxide (CO2) to grow algae and then produce bio-diesel has also benefitted the environment in terms of reducing greenhouse gases causing global warming. This translates into green credit points for Malaysia as well. While Malaysian bio-diesel using palm-oil as feedstock is fine it could become obsolete and non-competitive when more efficient feedstock such as algae are used for mass production of biodiesel and ethanol.

Ethanol from Wine - Wired report
Excerpts
1. An Italian company wishes to make ethanol-based fuel from wine.
2. Grape skins, like all plant matter, contain carbohydrates that can be broken down into sugar and fermented. And enough ethyl alcohol can be distilled from the skins to make a decent source of biofuel or gas additive.
3. The ethanol fuel made from wines is currently sold throughout Europe - but almost none of it in Italy, because of some confusing Italian regulations.
4. Few Italians want to imagine their sacred Sangiovese or Montepulciano grape going into something as unromantic as alternative fuel!
5. In a move known as "crisis distillation," the European Union last year tried to stem the plummeting price of European wine by allowing most member states to sell surplus wine to distilleries at reduced prices, and these were converted to ethanol!
6. European ethanol market is expected to triple in 2006.

Algae to Ethanol?
You are at: Oilgae Blog; see also: Oilgae - Oil & Biodiesel from Algae Home PageSome weeks ago there was an article on Veridium Inc. patent pending technology and an algae that contains up to 94% starch; the rest is possibly cellulose?
One member at the Oil from Algae Yahoogroup is wondering why all of us have focused on algae to (bio)diesel technology and not algae to ethanol technology...
To quote him further: "The two are not mutually exclusive. After all, the alcohol that goes into biodiesel has to come from somewhere"
He further says: "I can see many advantages to make ethanol from algae instead of diesel:
1.The lipid (oil) content in algae (best strains I have seen from different sources max. 70%) is less than starch+cellulose+ sugars(nearly 100%) content
2.Algae should be dried (a lot of energy) to extract oil but needs no treatment for ethanol fermentation
3.Extracting the oil from algae is complicated
4.CO2 from ethanol fermenting can be used as algae feedstock
5.The energy from fermenting and distilling can be used to heat algaeponds (photobioreactors) in cold climate."
Certainly food for thought!
