GS CleanTech Releases Process Demonstration of CO2 Bioreactor Technology

(Sept. 6, 2006)

Excerpts:

1. GS CleanTech Corporation announced its release of a process demonstration of GS CleanTech's patented carbon dioxide bioreactor technology.
2. GS CleanTech's CO2 Bioreactor efficiently converts a concentrated supply of CO2 into oxygen and biomass. The biomass output of the bioreactor can be harvested and converted into ethanol, biodiesel and/or biomass-derived synthetic fuels through an enzymatic process or, preferably, gasification followed by catalytic conversion into liquid fuels.
3. The oxygen output of the bioreactor has value for on-site power generation and gasification processes
4. A standard coal gasification facility converts coal into a hydrogen rich synthesis gas (syngas), which is combusted and converted into electricity in a gas-fired generator. The gasification process generates carbon dioxide (CO2) emissions which are usually compressed and sequestered underground. The carbon capture and sequestration stage of this process increases operating costs by more than 20% as compared to standard coal-fired gasification.
5. GS CleanTech's bioreactor consumes exhaust carbon dioxide and has the potential to offset the substantial operating and capital costs associated with conventional oxygen production while producing a valuable biomass co-product that can be used to enhance the plant's power output and/or add new revenues arising from the production and sale of biomass-derived fuels.
6. Impact on Ethanol Facilities - Ethanol production facilities consume corn and about one third of the mass exits at the fermentation stage in the form of carbon dioxide. GS CleanTech's bioreactor can be applied in ethanol plants as well.
7. GS CleanTech is currently deploying its first commercial scale pilot bioreactor system for ethanol facilities.
8. About GS CleanTech - provides applied engineering and technology transfer services based on clean technologies and process innovations for cost-effectiveness recyclability / re-usability.

Personalities mentioned: David Winsness, GS CleanTech's president and chief operating officer.

The process demonstration, as well additional technical and other information on GS CleanTech's CO2 Bioreactor technology, is available online at www.gs-cleantech.com.
