Research status and prospects for algae biodiesel: a review

With the aggravation of energy crisis and environmental pollution worldwide,biodiesel fuel has received more and more attention in recent years.At present,biodiesel is mainly derived from oil crops and animal fats,it can not meet environmental and economic sustainability.Lots of studies have shown algae are the most promising source for biodiesel production,so algae-based biodiesel has become more attractive.Because of its environmental benefits,algae-based biodiesel is considered as the most potential fuel alternative.As technologies for biodiesel production are sophisticated and costy,biodiesel production from algae is limited.This paper reviews the current status of microalgae used for biodiesel production,including its advantages and production process.Furthermore,production challenges and future perspectives for algae-based biodiesel production are also discussed.
