GS CleanTech’s Carbon Dioxide Bioreactor
Decreasing Emissions while Reducing Dependence on Foreign Oil
Greenhouse gas emissions and energy dependence are two of the United States largest concerns. During 2005 alone, the United States released into the atmosphere over 5 billion metric tons of C02, an increase of over 600 million metric tons since 1994. Carbon dioxide is a well known greenhouse gas that absorbs and traps the infrared radiation that is reflected off the earth’s surface causing surface temperatures to increase.
During 2005, the United States imported and consumed more than 200 billion gallons of oil. As our nation strives to become more energy independent and environmentally proactive, it is imperative that we implement new consumption practices that rely less on foreign oil and more on cleaner, greener sources of homegrown energy. We need to be better about conservation and we need to continue to innovate ways to consume natural resources in smarter, more efficient ways. GS CleanTech is committed to delivering innovative new technologies that help our clients achieve this and to help reduce their carbon footprint.
GS CleanTech’s Objectives:
GS CleanTech’s patented C02 Bioreactor reduces greenhouse gas emissions while creating an additional feedstock for renewable fuel production. If applied at ethanol facilities, it would boost fuel production by more than 15%, and if applied to coal fired power generation, it could produce more than 200 million gallons of renewable fuel annually for every 1,000 MW of electricity produced. Even more significant, however, is the relatively small footprint of the bioreactor. While traditional corn derived ethanol produces up to 450 gallons of fuel per acre, GS CleanTech’s C02 Bioreactor can produce more than 200,000 gallons of fuel per acre. With GS CleanTech’s C02 Bioreactor, our clients can reduce their carbon footprint while turning their exhaust carbon dioxide into a valuable source of clean, homegrown fuels.
GS CleanTech’s C02 Bioreactor is an enclosed structure with the ability to convert a concentrated supply of C02 into oxygen and biomass. The biomass can then be converted into fuel through traditional means.
All plants, including algae, need the following to live and grow: a supply of C02, light, a growth media and water with nutrients. The GS CleanTech C02 Bioreactor provides these resources in a compact, cost-efficient way.
First, concentrated C02 is captured at power plants or other source and piped to the bioreactor. The sunlight is then collected using efficient parabolic mirrors that transfer and filter the light to a series of light pipes. The light pipes channel the light into the bioreactor structure where it is distributed and radiated throughout the structure using light panels. The algae requires as little as 1.5% direct light which means that our collected light can be distributed over a substantial surface area.
Next, a growth media, such as polyester, is inserted between each lighting surface. Water, containing nutrients, continuously cascades down the growth media to facilitate the final required step for optimal growth.
Finally, to harvest the algae, the flow rate of the water over the growth media is increased slightly to gently remove a portion of the algae, allowing a portion of algae to remain and to begin the next growth cycle. The removed algae is then collected and routed for conversion into renewable fuels.
Our technology is also very flexible and can accommodate a variety of algae types. High starch, high oil, or high cellulose algae can be grown in our bioreactor depending on output fuel requirements.
GS CleanTech’s C02 Bioreactor has the ability to reduce our greenhouse gas emissions and to create an entirely new feedstock for cleaner and greener burning fuels. Our bioreactor can substantially reduce the amount of greenhouse gases that are produced from ethanol, power generation other industrial facilities while generating a significant new source of revenue. GS CleanTech’s C02 Bioreactor is profitable for our customer and cleaner for the environment.
Impact on Ethanol Facilities:
About one third of the mass of the corn input into the ethanol production process exits the process at the fermentation stage in the form of carbon dioxide. GS CleanTech’s patented bioreactor technology uses algae to consume these carbon dioxide emissions. The algae use the carbon dioxide in the exhaust, sunlight and water to grow new algae, giving off pure oxygen and water vapor in the process. If properly cultivated, the algae double in mass every 7 to 12 hours and are harvested for conversion into clean fuels as they grow to maturity.
GS CleanTech is currently deploying its first commercial scale pilot bioreactor system and anticipates use of the bioreactor technology at ethanol facilities to further enhance corn to clean fuel conversion efficiencies.
Impact on Coal Gasification
A standard coal gasification facility gasifies and partially oxidizes prepared coal with oxygen and heat into a hydrogen rich synthesis gas, or syngas. The syngas is combusted and converted into electricity in a gas-fired generator. The gasification stage of the process generates carbon dioxide emissions which, in some of the most advanced current practices, is compressed and sequestered underground in saline formations or the like. The carbon capture and sequestration stage of this process increases operating costs by more than 20% as compared to standard coal-fired gasification.
As applied at a coal gasification facility, 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.

Re: Convert CO2 into CASH
Cement industry is a big producer of CO2, which not only comes from combustion of coal being used as fuel but also produced as a by-product of the raw materials i.e., from calcination of limestone, which is 75% of the total raw materials. In this way, a 4000 tpd cement plant produces more than 2000 tpd CO2.
Can you please suggest a solution to use this CO2, which is an integral part of exhaust gases being released to atmosphere through chimney.
Re: Convert CO2 into CASH
Good information about the coal gasification process. I have started my coal gasification process with the help of one company that helped me a lot and i want to share that with you

Re: Convert CO2 into CASH
Well having gone through yours therad which thrrows the light to convert coal gas into fuel by innovative technology , i want to be a more specific with following platforms.
1) As in cement industry where we have massive productiono of coal gas whether this reactor will able to bring an alternate fuels . How ever it has already been enlightened and one can presume the same tech can bring such thing but what will be the actual process.
2) Now if at all i would to have this provision what will be the break even pint from financial aspects considering installation cost, maint cost and additional profitibility by using the same
To my knowledge hardly any cement plant using these tech in emerging market such as india , can you refer me a name of any cement plant using the same.
Awaiting for your reply
Thnx for your generosity.
