WILL IT BE POSSIBLE SOME TIME IN THE FUTURE TO DRIVE A CAR ON POPLAR POWDER

KOERA BIL PAA POPPELPULVER EN MOEJLIGHET I FRAMTIDEN

Utilisation of solar energy via the biomass from fast growing trees, reeds and turves appears promising. The annual yield of poplar is 4 kg dry matter per M2. 4 kg wood is equivalent to 2 l fuel oil. A growing area of 20000 km2, about 8% of sweden's total area, would replace the entire quantity of imported oil. A powder injection system for central heating boilers and diesel engines is under development. Poplar powder produced 0.2% ash. A powder diesel car would discharge about 4 g ash per 10 km. For the same range, the tank must be four times as large, but the weight is only doubled. Raw materials for biomass are: (1) about 8 M tons dry straw, equivalent to 4 M tons oil, are produced annually. (2) about 10% of oil energy can probably be replaced by reeds. (3) annual energy recoverable from turves is about 10 M tons oil equivalent. (4) poplars can be grown on wetlands. The raw material would be pre-ground to 0.5 mm. Energy needed is 0.01 wh/kg for reeds and 0.05-0.15 wh/kg for poplar. The material can be dried in rotary driers or drying towers. Straw and reeds contain hardly any water, while turves and wood contain 50%. Comminution requires 0.79 kwh/kg energy. (TRRL)
