New Biofuel Process to make Ethanol Involves Algae and Carbon Dioxide
DOW
The Dow Chemical Company recently announced today that it plans to work with Algenol Biofuels, Inc. to build and operate a pilot-scale algae-based integrated biorefinery that will convert CO2 into ethanol. The facility is planned to be located at Dow’s Freeport, Texas site.
Algenol’s technology uses CO2, salt water, sunlight and non-arable land to produce ethanol. This process certainly looks more promising and makes more sense as far as a method of capturing carbon dioxide than that of sequesturing it in empty oil wells and geological formations. It does not reduce the amount of atmospheric CO2 as it will be again released when the ethanol is oxidized in combustion. However as compared to gasoline or diesel production it does not release CO2 that is contained in a fossil fuel from millions of years ago.
Dow, National Renewable Energy Laboratory (NREL), the Georgia Institute of Technology (Georgia Tech) and Membrane Technology & Research, Inc. are contributing science, expertise, and technology to the project. Their combined expertise offers new and innovative technology, with the opportunity for creating a breakthrough process for ethanol production.
Andrew N. Liveris, Dow chairman and chief executive officer had this to say;
This project and the innovative technology involved offers great promise in the battle to help slow, stop and reverse the growth of greenhouse gas emissions. We are very excited to be part of this ground-breaking alternative energy project, which is a good example of Dow’s holistic approach to CO2 capture and storage by adding value through chemistry.
Algenol submitted its formal request last week to obtain a grant from the U.S. Department of Energy for financial support to successfully conduct the pilot. Upon approval of the grant, Dow and the other collaborators will work with Algenol to demonstrate the technology at a level to sufficiently prove that it can be implemented on a commercial scale.
In addition to leasing the land for the pilot-scale facility, Dow plans to develop the advanced materials and specialty films for the photobioreactor system. In addition, Dow will also provide the technology and expertise related to water treatment solutions and will provide Algenol with access to a CO2 sourcefor the biorefinery from a nearby Dow manufacturing facility. The CO2 will be supplied to the algae in thephotobioreactors and will serve as the carbon source for the ethanol produced. The result is a CO2 capture process which converts industrially derived CO2 into more sustainable fuels and chemicals.
In line with Dow’s sustainability efforts, the project exemplifies the Company’s commitment to providing solutions that improve energy efficiency, promote renewable energy and advance the environmental performance of its existing energy sources.
According to Rich Wells, Dow vice president, Energy & Climate Change and Alternative Feedstocks,
This is yet another way that Dow is helping to solve world energy challenges with our expertise in sustainable chemistry that is good for the world, and good for business.

About Algenol
Algenol today possesses the most advanced third generation biofuel technology in the United States.Algenolmakes low cost ethanol directly from CO2 and seawater using hybrid algae in sealed, clear plastic photobioreactors through its unique, patented Direct to Ethanol™ technology – all powered by the sun. Algenol’s research and development efforts have culminated in a process that produces over 6,000 gallons of ethanol per acre per year, compared to corn at 400. Algenol’s process achieves an energy balance of more than 5 to 1 and a life cycle carbon footprint that is merely 20 percent of petroleum (an 80 percent reduction from petroleum).
