Did you know? Algae are expected to yield 200 times the oil than most other field crops

Biodiesel‘s has physical properties very similar to conventional diesel (source: Alternative Fuels Data Center, Department of Energy, Govt of USA)

Kinematic Viscosity Specs & Standards

Specifications: (viscosities in mm²/s)

Europe Petrodiesel: 2.0–4.5

Europe Biodiesel : 3.5–5.0

US specification of viscosity for low-sulfur No.2 diesel fuel: 1.9-4.1 mm²/s (this is the fuel that is biodiesel is most often compared to)

US Specification for No. 1 diesel fuel is 1.3–2.4 mm²/s.

Most alkyl esters of vegetable oils have kinematic viscosities less than 5.0 mm²/s.
