Harvesting Algae for Biofuels

Algae are the fastest-growing plants in the world. Like other plants, they use photosynthesis to harness sunlight and carbon dioxide, creating high-value compounds in the process. Energy is stored inside the cell as lipids and carbohydrates, and can be converted into fuels such as biodiesel and ethanol. Proteins produced by algae make them valuable ingredients for animal feed.

GreenFuel uses a portfolio of technologies to profitably recycle CO2 from smokestack, fermentation, and geothermal gases via naturally occurring species of algae. Algae can be converted to transportation fuels and feed ingredients or recycled back to a combustion source as biomass for power generation. Industrial facilities need no internal modifications to host a GreenFuel algae farm. In addition, the system does not require fertile land or potable water.

A GreenFuel installation requires no retooling of existing facilities. Ongoing site operations are not interrupted, and the host facility is not exposed to hazardous materials or other risks.

A single pass through the GreenFuel system significantly reduces carbon dioxide in the waste gas. Using the sun as a source of energy, algae convert the CO2 into valuable compounds. Growing up to 30 times faster than other terrestrial plants, algae are regularly harvested for conversion into biofuels, feed, or can be recycled back to the host facility. Recycling algae in a closed system reduces the need for fossil fuels.
