Odyssey's Plan to Sequester CO2 Using Algae

A company called Odyssey Oil & Energy Inc. is now keen on the development of green technology, focusing on carbon sequestration and renewable energy. ALG Western Oil (Pty) Ltd, a subsidiary of Odyssey, is currently operating in a joint venture with Xstrata Alloys, a subsidiary of Xstrata Plc, the world's largest producer of ferrochrome in a project at one of Xstrata's Ferro-chrome smelters near Rustenburg in South Africa. They plan to capture and sequestrate the carbon dioxide emissions to get carbon credits.

Currently, all the carbon monoxide from the ferrochrome smelters is flared to carbon dioxide and released into the atmosphere. In their current pilot plant, they are cultivating a selected algae strain in photo bio-reactors, utilizing the carbon dioxide (CO2) flue gas coming from the exhausts of the generators, (with the aid of sunlight and some nutrients, through the process of photosynthesis) to sequester the environmentally harmful CO2 emissions and produce high value compounds such as vegetable oil, animal feed, etc., The next stage of the project will be on a commercial scale.

Latest Researches on Botryococcus braunii

Botryococcus is a genus of green algae. Botryococcus braunii species has gained lots of interest among the scientific community and biofuel industries due to its ability to synthesize and accumulate huge amount of lipids. Many researches had demonstrated that the biodiesel produced using the oil extracted from these microalgae is identical to diesel fuel. I have summarized some of the latest algae biofuel researches using Botryococcus braunii.

Researchers at Tsukuba University, Japan, have studied the oil yield of algae using Botryococcus algae. They have found that Botryococcus can produce fuel that is almost identical to diesel. They have achieved a production target of 1,000 metric tons per hectare a year in a laboratory experiment. They have planned to reproduce that outcome at a 1.5 billion-yen ($16 million) open-air pilot project starting in September, 2010.

Korean researchers have done a project on "selection of microalgae for lipid production under high levels carbon dioxide" using Botryococcus braunii, Chlorella vulgaris, and Scenedesmus sp. The results of the project suggested that Scenedesmus sp. is appropriate for mitigating CO2, due to its high biomass productivity and C-fixation ability, whereas B. braunii is appropriate for producing biodiesel, due to its high lipid content and oleic acid proportion (nearly 55%).

University of Bologna, Italy, had proposed a new procedure to extract hydrocarbons from dried and water-suspended samples of the microalga Botryococcus braunii by using switchable-polarity solvents (SPS) based on 1,8-diazabicyclo-[5.4.0]-undec-7-ene (DBU) and an alcohol. The high affinity of the non-ionic form of DBU/alcohol SPS towards non-polar compounds was exploited to extract hydrocarbons from algae, while the ionic character of the DBU-alkyl carbonate form, obtained by the addition of CO2, was used to recover hydrocarbons from the SPS. DBU/alcohol exhibited the highest yields of extracted hydrocarbons from both freeze-dried and liquid algal samples (16% and 8.2% respectively against 7.8% and 5.6% with n-hexane).

Pressure-Cooking Algae into Better Biofuel

Researchers at the University of Michigan are examining a method to pressure-cook algae at 300 degrees for 30 minutes, and thereby break down oils, proteins and carbohydrates into a crude bio-oil, which can be converted into fuel.

The high temperature and pressure allow the algae to react with the water and break down to release the native oil. Apart from oil, the proteins and carbohydrates also decompose and increase the fuel yield.

The hydrothermal process has two advantages over the large-scale algae-to-oil conversion techniques:
1.The method can be used to extract bio-oil from algae which contain less oil content.
2.It eliminates the drying process

The project was funded with $2 million from the National Science Foundation under the American Recovery and Reinvestment Act, and is aimed at producing acceptable fuel yields from low-oil content algae strains, as well as eliminating the need for water extraction in algal fuel production.

Genetically Engineered Algae for Biodiesel Production

Researchers at the Purdue School of Chemical Engineering along with Iowa State University got a federal fund recently to create genetically engineered algae that would produce environment- friendly biodiesel.The researchers are growing algae in a ?bioreactor' to study specific pathways that would lead to lipid storage. Accumulated lipids will be turned into biodiesel later.

The researchers planned to create a flux map (a method to study Steady-state metabolic flux analysis (MFA)) that would reveal the speed of reactions along many ?metabolic pathways' inside the algae. The researchers will also be developing algae that thrive in higher temperatures which natural algae cannot tolerate, for decontamination purposes. In addition, studies on ?carbon assimilation' which will lead to lipid storage will be conducted.

Stanford Researchers Produce Electricity from Green Algae

On April 13, Stanford University, California announced that its scientists have generated electricity from green algae in an environmentally friendly process.The study was conducted by WonHyoung Ryu in the lab of Professor Fritz Prinz. The researchers hope that one day this clean method of producing energy could replace the burning of fossil fuels.

The technology behind this invention involves trapping the algal cells with very thin gold needles--on the order of nanometer thickness (one-millionth of a millimeter). The cell membranes of the algae simply close around the gold needles. The algae produces electricity via photosynthesis, and the gold needles transmits the electricity to an external device that records the electricity.

Though the electricity generation from algae seems interesting, there is a long way to go before algae can replace fossil fuels. The research hasn?t satisfied the expectation for algae as an effective replacement for fossil fuels. The algae produced a miniscule amount of electricity--one picoampere per cell per hour. To put that in perspective, you would need a trillion cells in an hour just to produce the energy equivalent to one double-A battery. Therefore, the scientists need to generate more electricity in less time. Furthermore, the algae died shortly after the experiment, so scientists need to figure out how to generate electricity continuously without killing the algae.

Note: You can read the formal scientific paper in the March issue of Nano Letters.

Report Says, Algal Biofuels May Not Cut Carbon Emissions

Algae- based biofuel production and carbon capture are the hot-topics of research all over the world. On the other hand, a new study published in American Chemical Society journal, Environmental Science and Technology, suggests that the overall CO2 emissions to produce biofuel from algae may be worse than those from first and second generation biofuel feedstocks such as corn, canola (rape-seed) or switch grass.The report says though the algae-based biofuel production is advantageous than the above mentioned land-based crops when we grow algae in wastewater or near powerplants, algal fuels could cause an overall increase in carbon emissions when we grow them in freshwater(using additional nutrients and compressed CO2 source).

On closer inspection, the report is in fact very positive about growing algae. Read positively, the data are only in opposition to making fuel from algae if nitrogen and phosphorus nutrients are added in their mineral forms, and if the CO2 has to be injected into the system (transported as a compressed gas) as made mainly by the process of steam reforming methane, along with most of the world's available hydrogen:

(Overall) CH4 2H2O --> CO2 4H2.

That H2 is used to make nitrogen (ammonium sulphate and nitrate) fertilizer by reacting it with N2 via the Haber Bosch process to make ammonia (NH3), and so there is in a way a symbiosis between the production of CO2 and NH3. The phosphorus would likely come from mining "rock phosphate", which requires energy too.

The US Algal Biomass Organisation has claimed that the study contained "faulty assumptions" and was based on "grossly outdated data". Even if there remains some dispute over the exact figures used, what the study does highlight is the importance of developing an integrated paradigm of production and recycling for algal fuel production.

Green Algae + Human Waste = Green Power

An algae-based wastewater treatment project is planned to be started in May, at Laguna wastewater treatment plant in the city of Santa Rosa, California.The pilot plant relies on native algae and marsh plants to purify sewage and produce methane.The methane gas will run a generator that charges a fleet of four electric maintenance vehicles.

The project is co-ordinated by Sonoma State University biologists. They have constructed six algae ponds at Laguna to clean a small portion of the wastewater stream, meeting state standards for nitrates and phosphates.Laguna serves a population of 250,000 people, and it would require more than 100 acres of algae ponds to purify the entire waste stream of nitrates.The current project measures only 800 square feet. Treddinick, the project development manager for the city's Utilities Department, plans to scale up the project to an acre.

Michael Cohen, the Sonoma State biologist who oversees the algae operation said they planned to extract oil from the algae, though they are aware of the fact that extracting oil from algae is a tough process. This is because of the variation in oil content of algae species and difficulty in extracting oil due the tough cellwalls of algae.

"We knew going in that we were going to be fighting a losing battle, but we thought we would see if we could make it work", said Hare, who is Cohen?s student at Sonoma State.

Continuous Ethanol Production Using Closed Photobioreactors

Here is a description of a patent from USPTO Patent Application 20100068801,"Closed photobioreactor system for continued daily in situ production of ethanol from genetically enhanced photosynthetic organisms with means for separation and removal of ethanol".

The aim of the invention is to provide a large volume photobioreactor for the continuous cultivation of genetically enhanced cyanobacteria or algae for the production of ethanol and other biofuels. The photobioreactor allows the in situ separation of ethanol from culture media. This is achieved by evaporation and subsequent condensation using sunlight.


The closed photobioreactor contains a chamber which comprises a headspace - an upper part of the chamber which comprises a translucent region to allow sunlight. The lower part of the chamber comprises an aqueous growth medium comprising a culture of genetically enhanced organisms.Specific strains are selected from the group of algae and cyanobacteria and the selected srtrains enter the growth medium and produce ethanol on a continued, daily basis.The ethanol in the growth medium evaporates into the headspace, condenses on the inner surface of the upper part of the chamber. Finally, the etahnol is collected in a collection trough and released through outlets.

The major advantage of the invention is the removal of ethanol from the culture comprising genetically enhanced cyanobacteria or algae, wherein the ethanol is removed from the culture without additional external energy.
