Algen voor Energie

Oppervlakte van IJsselmeer voldoende om olie te maken voor alle auto’s in Nederland.

12/28/06 - Pond Scum for energy
Pond scum, or algae, a plant that for decades has been prized as a possible commodity crop based on its unparalleled ability to photosynthesize solar energy into plant biomass for food. Unlike most plants, algae shares characteristics of bacteria, and its photosynthetic machinery operates much faster in converting inorganic substances into organic matter. And while plants require a lot of fuel to sow and harvest and additional fertilizer and fresh water to nourish, algae can be continuously harvested from closed water-based bioreactors that require little additional replenishment other than inorganic fuel supplied in the form of waste gas. “Right now we’re using soybean oil, because canola is more expensive,” Dommermuth adds. “Soybeans can give you 50 to 60 gallons of oil an acre compared to 75 to 125 gallons for canola, but algae is almost limitless because it grows so fast, so potentially you could get 10,000 gallons per acre.”

Algen kunnen 45,000 liter olie per 4.000 m2 leveren (10.000 gallons olie per acre).
Met 5 miljoen auto’s in Nederland die gemiddeld 20.000 km/jaar rijden en 1 : 10 rijden (1 l / 10 km) is voor alle brandstof van alle auto’s in Nederland zo’n 100.000 ha voldoende. Ofwel een oppervlakte ongeveer zo groot als 3% van de landoppervlakte van Nederland, of ter grootte van het IJsselmeer of 40% van Flevoland.
