Algae is a personal favorite of ours here at green.mnp, as you can see here, here and here, and some of you may have seen in the October issue of National Geographic. Well, here is another exciting algae harvesting technology we came across by Valcent Products Inc. They call the technology Vertigro, and I will let their CEO Glen Kertz explain the rest (double click his face to watch the video):
Data received from Valcent’s continuously operating test bed facility demonstrates that yields up to 4,000 barrels oil per acre, per year, at an estimated cost of $20 per barrel are achievable on a commercial scale. As a comparison, typically corn will yield up to one-half a barrel of oil per acre per year at considerably higher cost; palm oil, with highest yield of conventional sources, delivers approximately fifteen barrels of oil per acre per year. After a demonstration pilot plant is in operation, several production units that may total 1,000 acres may be built which would have the potential of producing approximately 4,000,000 barrels of oil per year, with significant carbon dioxide green credits and other commercial products. At that rate of production, Vertigro will sequester approximately 2,700,000 tons C02 per year which will be sold as a green credit within the emerging green credit system within the USA and within the Kyoto Protocols.
Interestingly, Valcent has also applied the concept of the Vertigro technology to growing herbs and veggies. They call it the High Desity Vertical Growth System:
