Seaweeds contain a high volume of sugar which can be converted into Ethanol. So far the best sources for Ethanol production are corn and sugarcane, however theses sources are problematic as the production requires farm land. The demand for Ethanol is rising as new engines are manufactured to run on up to a gas mix of up to 85 percent Ethanol. This result in more farm land required to produce corn and sugar cane, not only in the US but in other countries as well. EPG Fuels has thoroughly examined various species of seaweed and forund that it is possible to extract up to 60 gallons of Ethanol per son of dry seaweed
The advantages of using seaweed for Ethanol production is that the cultivation of seaweed does not require farmland. EPG Fuels has successfully cultivated seaweed on in enclosed water cultures for prolonged periods of time. The growth rate has been high and on a average of 50 grams dry seaweed per meter square. These numbers translate to 445 pounds of dry seaweed per acre per day. In comparison corn grows at a rate of 25 pounds per day.
With the development of new and multiple purpose enzymes it is possible to extract more Ethanol from algae that it was just a few year ago. At EPG Fuels we are aware of extraction of up to 80 gallons per dry ton of algae. Besides material for both food and energy the algae contains valuable material for the medicine industry.
