Question: What are some disadvantages to third generation biofuels?

Answer: In order to produce biofuels from algae sources the mixture must be made uniform and the current industrial methods of doing this are to agitate the mixture sort of like a blender. Unfortunately this inhibits the growth of the algae and so production is essentially limited or slowed by the very act of creating the biofuel. This disadvantage makes yields less than they would otherwise be and is a significant hurdle towards bringing third generation biofuels to market.

Another disadvantage of third generation biofuels is that extraction of the algal oil is difficult and costly. More methods are being developed all the time though and it’s looking like this won’t be a disadvantage for much longer.
