Exxon Enters Biofuels Field by Looking at Algae

DonnaWilliamson-AP Behemoth oil giant Exxon Mobile has announced that it will invest $600 million in producing liquid fuel from algae. It will spend $300 million on in-house research and partner with Synthetic Genomics, a biotechnology company founded by J. Craig Venter, the man who mapped the human genome.

Long known for its poor environmental practices and denial of climate change, Exxon’s entry into the field of biofuels will be welcomed by some and viewed skeptically by others. For a company that made $45.22 billion last year, a $600 million investment could be seen as more of a PR investment than a scientific commitment.

Algae has become a popular choice for biofuels due to its high energy potential. Exxon thinks it can produce more than 2,000 gallons of fuel per acre of production each year. Compare this with corn ethanol, which yields only 250 gallons per acre a year and has significantly lower energy potential than the lipids produced by algae.

Furthermore, algae can be grown on land or brackish water that does not compete with food crops (perhaps even in salt water). Venter said he also believes that algae can be engineered to consume huge amounts of carbon dioxide when it's grown, offsetting carbon emissions from power plants.

For its part, Exxon warns that any large-scale commercial algae fuel plants are five to 10 years away, with numerous obstacles still to overcome.

It’s one thing to produce small amounts of fuel from algae, but this is not the scientists’ task. Rather, they must figure out a way to produce synthetic fuel that's cheaper than gasoline and can put some sort of dent in the 9 million barrels of gasoline the U.S. market consumes every day and the 138 billion gallons it eats each year.

"Venter said he also believes that algae can be engineered to consume huge amounts of carbon dioxide when it's grown, offsetting carbon emissions from power plants."


Yes, the algae will absorb CO2, perhaps that which comes from power plants, however as soon as that algae biodegrades (or it's byproduct, ethanol, is burned), the CO2 is released into the atmosphere. Therefore there is no offsetting of carbon emissions at all, just a delay.

The offsetting that this technology creates has nothing to do with power plants. By using the ethanol that is produced by the algae we don't use oil in its place, thereby eliminating those carbon emissions.


What's the cost in water usage to grow the algae?


Dan you are full of crap. Algae does not produce alcohol, it produces biodiesel fuel. You know nothing about carbon offsets, so spare us your misleading posts.


In case you didn't know, ethanol is alcohol. Algae produce lipids.

The entry of the Exxon in the bio fuel sector is a very sign for the sector as well the company . The investors of the Exxon should be proud of these investments. I also recommend the writers and blogger to visit the website http://investmentsinenergy.com because this energy site has plenty of info on bio fuels and other clean energy, that would enrich your knowledge regarding the clean energy sector
