"This paper examines the greenhouse gas, costs and energy balance on a life-cycle basis for algae grown in salt-water ponds and used to produce biodiesel and electricity. Under the conditions described and the data assumed, it is shown that it is possible to produce substantial greenhouse gas and energy balance advantage over fossil diesel. However, when scaled up to large commercial production levels, the costs may exceed those for fossil diesel. The economic viability is highly dependent upon algae with high oil yields capable of high production year-round, which has yet to be demonstrated on a commercial scale."
