GreenShift's CO2 Bioreactor
GreenShift's patented CO2 Bioreactor reduces greenhouse gas emissions while
creating an additional feedstock for renewable fuel production.
Patented process uses algae to consume greenhouse gas emissions from
fossil-fueled combustion processes such as power plants. The algae use the
available carbon dioxide in the exhaust and water to grow new algae, giving
off pure oxygen and water vapor in the process. Light from concentrated
solar panels is conducted into the algae chambers via fiber optic cables.
The organisms also absorb nitrogen oxide and sulfur dioxide. Once the algae
grow to maturity, they fall to the bottom of the bioreactor and are
harvested for conversion into ethanol and biodiesel fuels.
GreenShift's CO2 Bioreactor is an enclosed structure with the ability to
convert a concentrated supply of CO2 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 CO2, light, a growth media and water with nutrients. The GreenShift CO2
Bioreactor provides these resources in a compact, cost-efficient way.
First, concentrated CO2 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.
