Microalgae could be a profitable source of biodiesel
Date:3/21/2013

s cover large areas of land and need huge amounts of fresh water, and their use implies diverting food products to the energy market.

The possibility of creating energy from hydrocarbons extracted from organisms like marine phytoplankton, the so-called third-generation biodiesel, has several advantages. Firstly, algae offer the same production levels while taking up only between 4 and 7 per cent of the area occupied by crops on land, thanks to their high concentration of energy per cell. Secondly, they do not need fresh water, as sea water is sufficient, which makes them viable even in deserts or arid areas near the coast. Finally, marine algae are not, a priori, sources of food for human consumption, which avoids the ethical problem of monoculture to provide fuel rather than food.
