Third generation micro algae feedstock cultivation and fuel production have sustainable and economic benefits due to their microscopic nature. Each process in the production of micro algae biodiesel such as cultivation, harvesting and extraction can be optimized to negate the factors affecting production. Optimized micro algae biodiesel blends can be utilized to obtain ideal engine maps by calibrating engine parameters at stationary or dynamic engine tests. Numerous studies are available on micro algae based biodiesel production and its application in IC engines. Even though few consolidated articles are available on the effects of using micro algae biodiesel in IC engines, little to no article is available clubbing the production and optimization aspects of micro algae biodiesel with engine testing. To address this issue, this article intends to consolidate studies which have utilized different reactors for cultivating diverse micro algae species with multiple growth mediums. Furthermore, this combination also includes different biomass preprocessing and extraction techniques in producing micro algae biodiesel. Also, the implementation of micro algae biodiesel in IC engines and its output characteristics for different micro algae biodiesels have been highlighted and analyzed. To understand the current commercial status of micro algae biodiesel, a techno-economic analysis has been drawn. Studies revealed that closed type reactors are effective for continuous cultivation due to the constant regulation and availability of optimized growth factors. Furthermore, the techno-economic assessment revealed that the maintenance costs involved in the production should be lowered by 2–3 times the original to make micro algae biodiesel commercially available. © 2020 Elsevier Ltd
