Are algae currently a commercial crop?
Yes. Algae are grown commercially around the world, primarily for nutritional, feed, and specialty product use. What is required to grow algae? The primary requirements for growing algae are sunlight, water, and carbon dioxide (CO2). Algae also require nutrients and environmental conditions appropriate to the specific algal species. Algae are known to grow in environments as diverse as the arctic and hot springs. Does GreenNRG grow algae using the CO2 in our atmosphere? No. GreenNRGs technology consumes high concentrations of CO2 (between 5-30%) as it is emitted from power, cement and chemical plants before it is absorbed into the atmosphere. Atmospheric CO2, at less than 0.04%, is not concentrated enough to deliver the productivities we are seeking. Does GreenNRG grow algae in open ponds? No. GreenNRG algae farms are enclosed systems resembling greenhouses. They are often called algae-solar bioreactors. What kind of algae does GreenNRG use? GreenNRG selects microalgae based on a numbe
